Yagma of medical physics. Ultrasonic poisoceramic reversal Model with sub-winding
A sealed ultrasonic converter is used for transmitting in rare cases the middle of ultrasonic rings to place a sealed housing with a diaphragm, which is partly on the surface of the housing, in the middle of which is loosened and secured to the diaphragm 'Isoelectric vibrators, electrodes, which are electrically connected to high P'ezoelectric vibrating high-frequency electrical voltages from an ultrasonic frequency generator.
Vikorist is used to awaken in rare cases ultrasonic cavitation, which ensures the intensification of the cleaning processes of parts from clogging. Stand near ultrasonic cleaning baths with a volume of over 50 liters.

in U.Z. baths
The device of the ultrasonic sealing device is shown schematically in Fig. 1.
The generator is connected to 220 volts 50 Hz and changes the voltage frequency to 25,000 Hz (25 kHz) or 35 kHz. carefully in accordance with the design of the enclosed re-creator.
The high-frequency voltage is supplied through a cable into a sealed converter housing, made of stainless steel, in the middle of which there are mounted pyroelectric power generators connected in parallel.
Fig.2 Device of a piezoelectric viprominuvac
The piezoelectric viprominyuvach is the main unit of the ultrasonic transducer. The device of this viprominyuvach is shown in Fig. 2.
The viprominuvach contains two p'iesoelectric plates (p'esoelements), spread between two metal plates: rolled steel on the back side and aluminum on the front.
The piezoelements are tightened together with the linings using the central bolt. A high-frequency voltage is supplied to the central electrode, located between the electrical elements.
The piezoelectric power generator converts electrical energy into high-frequency mechanical vibrations, which are transmitted to the diaphragm of the internal converter, whereby the vibrations are transmitted to the surrounding area.
The number of p'ezoelectric generators in a pre-wired ultrasonic converter can range from 4 to 11 or more.
The piezoelectric vibrators are secured to the diaphragm using an adhesive backing.

The hidden appearance of the ultrasonic sealed transducer from the partially creased back cover of the readings in Fig. 3. It can be seen that the piezoelectric viper-prominences are arranged in a number of rows, two in each row.
Ultrasonic cleaners can be used either in ultrasonic cleaning baths specially designed for them, or in regular baths, which are also available at the washing station. The strength of these devices is that they can be easily installed in various parts of the bathtub.
In addition to ultrasonic transformers, which are carefully attached to the cleansing bath from the bottom or side, the sealed transformers can be replaced with a strand of several strands.
The generator for the vitalization of wire transformers with high-frequency voltage can be deployed in an ultrasonic bath at a distance of up to 6 meters.
Methods for installing wall re-creators near an ultrasonic cleaning bath
Wall-mounted transformers can be placed near bathtubs to cleanse the interior in a variety of ways:
- the placement of the bathtub is redesigned;
- hung on the bathtub wall;
- remount the fixtures on the bath station.
Fig. 4 Placement of the redesign in the ultrasonic bath
The first two ways are not to open the openings at the bathtub station.
The different types of fastening of the sealed valve in the bathtub for ultrasonic cleaning are shown in Fig. 4.
When placing the valve on the bottom of the bath, adjust the height of the ball above the diaphragm of the valve.
The trace should be bent until the height of the ball is a multiple of half the height of the ultrasonic rocks, which are transmitted to the migrating department by a re-creator.
As a result of the collapse of the vibrations of ultrasonic vibrations in the water-surface cordon, a zone of standing waves (a reverberation zone) is created. When reverberating ultrasonic tubes, ultrasonic cleaning of the material is effective.
As a butt, the optimal height of the ball for a particular sealed rework is important.
Apparently, the speed of sound near water becomes 1485 m/s. Over the past few years of ultrasonic vibrations, ancient particles have been produced at the same speed as the frequency of sound.
It is acceptable that we can set the frequency of the diaphragm to 25,000 Hz (25 kHz). The height of the hvil in this form will be 0.0594 m. Half of the dovzhina of the hvil will be 0.0297 m or 2.97 cm. The optimal height of the rudina in this form above the surface of the engraving is 2.97 cm x n Is not a positive number .
Fig.5 Standing spines in an ultrasonic bath
For example, for n = 40, the optimal height of the edge of the flange above the surface of the engraved border becomes 2.97 x 40 = 118.8 cm. It is more clearly illustrated in Fig. 5.
The placement of internal ultrasonic transformers on the walls of the cleaning bath is recommended in cases where the depth is greater than the minimum width or depth. In this case, the transformers can be placed either on one station of the bath or on the adjacent walls.
The video shows the placement of sealed transformers on the side walls of the bathtub and the robot of sealed ultrasonic transformers located on the bottom of the bathtub.

Vibration of the optimal frequency for digital transformation
At the RIDINIL Ultrasvukovikh colivan Viniki, the nickname, the corner of Kavitatsiyu, the pid for the roseman of the dullness of the ribi -kitatsyinhin at the phase of the sound of the sound of the bivili і is away from the phasi of the wasnnie.
Fig.6 Frequency influx to ultrasound cavitation
The behavior of cavitation emptyings when changing the cavitation frequency is shown in the graph in Fig. 6.
The ordinate axis on the left side shows the amount of energy that is seen when a single cavitation drain is closed (cavitation energy), and the ordinate axis on the right shows the number of cavitation voids per unit volume. and.
As can be seen from the graph, with an increase in the frequency of ultrasonic vibrations, the number of cavitation empties in the area increases, and the energy of cavitation changes.
With a decrease in the frequency of ultrasonic vibrations, the amount of cavitation emptyings near the center changes, and the cavitation energy increases.
When the skin frequency of ultrasonic vibrations of solid cavitation energy is empty, which is seen when it is slammed to the number of bulbs in the same area, the value of the constant approximately equal energy transferred to the One single ultrasonic re-creation.
A detailed description of the frequency infusion of ultrasonic vibrations into the volume of empty cavitation can be found on the website
For practice, it is important that the number of cavitation voids be much larger, in order for the cavitation energy to be generated to be sufficient for the formation of congestion. In this way, to clean the parts that are contaminated with the surface (fats, oils) the traces should be mixed with a frequency of 35-40 kHz and to clean the parts that are contaminated with the surface (polishing pastes, varnish and polymer no spitting) trace set the circuits at a low frequency of 20-25 kHz.

Fig. 7 Ultrasonic bath with switches of different frequencies
The most optimal solutions are the creation of such minds, if the number of cavitation voids would be great and in which case the energy of cavitation would also be great.
These washes are carried out in an ultrasonic cleansing bath with lined transformers placed on its walls, as shown in Fig. 7. Another option for expanding the patterned transformations can be found by moving the cursor to that little one.
In this case, there are two switches with different frequencies of 25 and 35 kHz. Converting with a frequency of 35 kHz ensures the creation of a large number of cavitation empties, and converting with a frequency of 25 kHz increases the energy of cavitation. empty
Optimal strength of sealing agents for cleansing baths
With a given number of necessary cleaning agents, the requirement comes from the fact that the maximum effectiveness of ultrasonic cleansing is achieved with an ultrasonic pressure of 10...30 W per 1 liter of bath volume.
So, for example, for a bathtub with a volume of 50 liters, two redesigned models PP25.8 are sufficient (see table below).
For large-scale ultrasonic cleansing baths, for example, over 250 liters, satisfactory results are achieved with an ultrasonic pressure of 4.5 watts per 1 liter of bath volume. For example, for a bathtub with a volume of 1000 liters, 11 reversible models PP25.8 are sufficient
Currently, there are a lot of designs of ultrasonic sealing machines on the ham market.
The table shows the technical characteristics of ultrasonic converters of the TOV TNC Technosonic company (Moscow).
This article does not cover all aspects of the design and operation of ultrasonic transducers. However, the material may be of interest to farmers, who are first faced with specific tasks in choosing the optimal option for an ultrasonic bath for purifying germs.
Ultrasound is a spring acoustic wave that cannot be sensed by humans, the frequency of which exceeds 20 kHz. Low-frequency (20...100 kHz), mid-frequency (0.1...10 MHz) and high-frequency (over 10 MHz) ultrasonic vibrations are commonly used. Regardless of the number of megahertz, ultrasonic waves should not be confused with radio waves and radio frequencies. These are absolutely different speeches!
Due to its physical nature, ultrasound is in no way different from the original sensitive sound. The frequency between sound and ultrasonic vibrations is intelligible, and is determined by the subjective powers of human hearing. To top it all off, high-frequency vibrations are well received by creatures (both domestic and domestic), and bats and dolphins are respectful in life.
Ultrasound always expands well in fluids and solids. For example, ultrasonic waves fade away in water about 1000 times less than in wind. The stars highlight the main areas of their stasis: hydrolocation, control of viruses that do not destroy, “sound suppression,” molecular and quantum acoustics.
To generate ultrasonic waves, use the following types of ultrasonic transducers:
Piezoceramic (piezo);
Electrostatic;
Electromagnetic (electromagnetic).
For the remaining option, use primary high-frequency sound generators (in the slang, “squeakers”), which can provide sufficient CCD to generate signals in the near-ultrasonic range of 20…40 kHz.
P'zoceramic ultrasonic vibrators (Table 2.10) are produced, as a rule, in pairs with suitable frequency receivers. Typical parameters of the “ultrasonic tandem”: resonance frequency 37...45 kHz, sound pressure level at a distance of 30 cm - 95...105 dB(A), operating voltage 12...60 V, capacity 1000...3000 pF , output transmitting impedance, input receiving impedance 10 ... 30 kom.
Table 2.10. Parameters of ultrasonic viprominuvacs
It is recommended to apply not unipolar, but opposite-polar pulses to the plates of ultrasonic piezo emitters. At pauses, form a voltage of reverse polarity. This ensures an accelerated discharge of the equivalent capacity of the compressor and the increased speed of the liquid code.
Rice. 2.53, a...l is provided with diagrams for connecting ultrasonic vibrators to MK. To form multipolar pulses, transistor bridges and separate transformers are widely used.

Ultrasound viprominyuvach is a generator of ultrasonic pressing pressure. Apparently, humans cannot sense the ultrasonic frequency, but the body does. In other words, the ultrasonic frequency is perceived by the human ear, but the small part of the brain that represents hearing cannot be deciphered by the sound. Those who deal with everyday audio systems are guilty of knowing that high frequency is no longer acceptable to our hearing, but if you raise the frequency to a high level (ultrasound range), then the sound is heard, but it really doesn’t matter. The brain will try unsuccessfully to dissipate the sound, which will result in headaches, boredom, vomiting, confusion, etc.
Ultrasonic frequency has long been stagnant in various fields of science and technology. With the help of ultrasound, you can weld metal, carry out a lot of other things. Ultrasound is actively used to remove rodents from rural technology, the fragments of the body of many animals are combined until they are amalgamated with something similar to the ultrasonic range. There are also data about the treatment of comas with the help of ultrasonic generators; there are many companies producing such electronic repellents. And we encourage you to independently assemble the following device according to the following diagram:
Let's take a look at the design to achieve simple ultrasonic harmonics with high tension. The D4049 chip acts as an ultrasonic frequency signal generator and contains 6 logical inverters.
The microcircuit can be replaced with a domestic analogue K561LN2. The 22k regulator is needed to adjust the frequency, and it can be reduced to a specific range by replacing the 100k resistor with 22k, and replacing the 1.5nF capacitor with 2.2-3.3nF. Signals from the microcircuits are fed to the output stage, which is generated by 4 medium-voltage bipolar transistors. The choice of transistors is not critical; the main thing is to select complementary pairs that are as close as possible to the parameters.
As a matter of fact, you can literally use HF heads with a pressure of 5 watts. From the domestic interior, heads of types 5GDV-6, 10GDV-4, 10GDV-6 can be installed. Such HF heads can be found in the acoustic systems of the SRSR.
There was no need to formalize everything in the building. To ensure directness of the ultrasonic signal, it is necessary to use a metal reflector.
It is important to relate to ultrasonic technology, devices for intensifying technological processes in rare media, and can be found in the mechanical, electronic, pharmaceutical industries, baths and atomic energy. An ultrasonic poisoceramic transformer includes a housing with a vibrating membrane installed at the cut-off opening, which is known as one of the following: It has the functions of an extinguishing damper, which allows the body to work in aggressive media in Vikonan. z titanium. And when several viprominuvachs are installed in the housing, it is important to select one quarter of the entire ultrasonic oscillator. Proposition of wines is based on the design of the converter, promotes the effectiveness of ultrasonic chisels when working in aggressive media and ensures reliable sealing of the body against leakage in the middle, which is sounded. 4 salary f-li, 4 il.

Wines are applied to ultrasonic technology, and to devices for intensifying technological processes in rare media: cleaning of parts, extraction, etching, leakage, and can detect stagnation in machine-generating electricity, chemical, electronic, pharmaceutical industry, industrial and nuclear energy.
We use a whole series of ultrasonic piezoelectric transformers, in which the sealing elements of their internal structure are formed by the new infusion of rare Vikon fluid in the form of fluoroplastic or humic reinforcements. There is a special part of the fire: when they are installed in heavy-duty resin converters, the stench will react under the influence of ultrasound, as a result of which a leakage will occur through the middle of the body and will therefore come out of order. (Div. Patent for corisna model of the Russian Federation No. 66700, B06B 1/06 “Ultrasonic p'ezoceramic re-creator”, published on November 10, 2005, as well as the Russian Federation patent for vinahide No. 20090013, H04R 17/00 “Appliance 09.10.19.” 97 R.)
In this manner, all similar transformations are subject to stagnation.
This is also a standard ultrasonic device for sounding the area near the bathtub, which includes a plastic plate, a membrane and an element for securing the device to the bathtub. To ensure proper sealing of the internal empty part of the valve while leaking through the middle, a gullet ring is installed at the groove of the body. To heat a large area, the sound of the pool of the bathtub is one row. However, in this case there is no problem of sealing, as debris may get into the inner empty housing due to wear of the pressure ring and weakening of the threaded connection. (Div. RF patent for vinahid No. 2009720, B06B 1/06 “Ultrasonic high-frequency converter for sounding the body in the bathtub”, published 03/30/1994)
There is also an ultrasonic ceramic-ceramic converter for sounding the core, which places a vibrating lining, a plastic bag, a reinforcing pin, a flange, a ring reinforcement, a nut, a pin for fastening to the bath, and acoustically releases membranes at the ledge there is a damper. In this case, the flange and the ledge of the membrane are tightly tied together to each other. Additional sealing is achieved by a gum or fluoroplastic ring, which is attracted to the bottom of the bath by moving the nut along the pin.
Damping from the appearance of permanent cracks is provided by a plastic ring. (Div. Author's certificate of the SRSR No. 1622025, B06B 1/06 “ultrasonic poezokeramic converter for sounding the sound”, published 01/23/1991)
The main disadvantage of this design is the foldability of the assembly of the transformer to the bottom of the bath, since the thickened humic or fluoroplastic ring does not ensure reliable long-term sealing of the transformer from the bottom , which is voiced by him, especially in times of aggressive acids or meadows.
You can also see an ultrasonic poisoceramic transformer with a viprominuvach, inserted from the outer side of the bottom of the container with a fastening element that looks like a welded seam and a threaded connection. (Certificate for the RF model No. 35250, IPC B06B 1/06, published 01/10/2004) Danish ultrasonic poisoceramic converter of vicors in the device for cleansing the area, which includes the capacity, to the bottom of any on the other side of the attachments. In this case, the element for fastening the fittings in the form of a bushing with internal grooves is rigidly fixed to the bottom of the container using welding, and the security of external grooves is possible Screw it into the sleeve until it stops at the bottom of the container. In this device, which is attached to a chair, the problem of sealing is mainly due to the way the seals are secured to the bottom of the container from the outside side. However, in this case, the intensity of ultrasonic vibrations cannot be lost, so that the remaining ones are transmitted, firstly, through the wall of the container, and in another way, an end gap is created at the threaded joint, so Beware of frequent wastage of effort and prominence Therefore, it is practically impossible to perfectly fit the surface of the bottom of the container and the end of the container.
Therefore, it is necessary to simplify the design by turning off the threaded connection. The specification of the proposed input is based on the shortcomings of analogues and the prototype, and to ensure re-sealing of the leakage medium, which is sounded, and to achieve the maximum possible intensity of I work in my country.
The task is to sound the very middle, which is located in the tank for processing viruses with one-hour neutralization of the waste membrane of the ultrasonic converter.
The technical result that lies in the simplified design of the device with an immediate increase in the intensity of ultrasonic vibrations in the area is achieved in the same way as one of the following types of installations in the drainage hole. the minimum membrane or the membrane bottom of the body with the possibility of direct contact of the body with a sound line when it comes to the body, connected to a material with low acoustic support (titanium), hermetically connected to the body with a welded seam, which provides an additional function of a damper for extinguishing the damage of the vibrating membrane. To ensure a smooth connection with a welded seam to the body of a viprominuvach vykonaniya of T-like shape with a head in the form of a bead, which overlaps the opening of the membrane bottom along the entire perimeter by an amount of 2-5 mm, ensuring a uniform zone 'Ednanny from one and the same metal and the smut, titanium has a low acoustic support, which minimizes the cost of tension of ultrasonic chisels in the smut The name that is in contact with the environment that is voiced.
Ultrasonic poisoceramic transformation is new, but in the information sections, the totality of the corresponding symbols displayed in the output formula, including additional points, has not been identified.
Reproduction of ultrasonic ceramic ceramic re-creation as a technical solution is the winemaker's rhubarb. On the other hand, in industry, especially in heat exchange systems, it is often necessary to remove from the surface of parts the mechanisms of persistent salt deposits and various scales, in which the breakdown of aggressive media in the form of acids and meadows occurs. To remove such defects, it is necessary to apply a more intense ultrasonic treatment, at the same time, the ultrasonic treatment is required to create a compact shape and firmly remove the influx of aggressive substances. Proposition of an ultrasonic poisoceramic transformer demonstrates these benefits. The high thickness of the spreading of the viprominuvach on the membrane of the converter body, the low acoustic resistance to titanium and the direct distribution of the working surface of the viprominuvach’s hydraulic fluid into the sound environment allow to ensure the The maximum physical strength possible for the combination of the intensity of ultrasonic vibrations and the maximum possible intensity of cavitation infusion.
The technical solution is not obvious, the fragments of the welded seam, formed by the material described, are not only stuck as an element for fastening the hydraulic valve to the valve body, but also the function of the extinguisher damper іння згілнях kolivan. Thus, two functions: fastening and extinguishing of gaskets are combined in one sign, which led to the simplification of ultrasonic processing and at the same time to an increase in the intensity of ultrasonic vibration.
The constructive validity and associated functions were not identified in the information, scientific and technical literature and patent materials, which indicates the non-obviousness and originality of the proposed ultrasonic printer a wonderful re-creator. This significance, in our opinion, cannot be transferred to the method of primary engineering design.
The preparation and testing of the last samples showed their feasibility and confirmed the achievement of the technical result assigned in the description of the output, which corresponds to the criterion of “industrial consistency”.
The housing of the re-forming of the sealed frame can be sealed as a sealed option, but it can also be installed in the working tank.
The figure is illustrated with armchairs, where figure 1 shows the body of an ultrasonic poisoceramic switch with a spacer (viewed from the side), figure 2 shows a viper membrane with viper membranes, arranged in one row, figure 3 shows a vipro This membrane with viprominuvach, placement in two rows, in Fig. 4 there is a hidden appearance of the converter for closed containers with a different appearance in the section. An ultrasonic poisoceramic converter replaces the housing 1 with a viscous membrane 2 with a continuous opening 3, in which installations, using one poisoceramic viprominuvator 4, which includes sound transmission One coil 5 of T-like shape with a collar 6 and a flattened surface 7, reinforcing stud 9 and steel nut 10. Sound-proof coil 5 of the flexible membrane 4, tightly inserted into the hole 3 of the bottom or of the flexible membrane 2 (Fig. 4), connected behind an additional shoulder 6 of the flexible membrane or the bottom of the container with a sealed seam. 7 hvilevoda 5 is in contact with the middle, which is sounded directly, which increases the intensity of ultrasonic vibrations. The welded seam is formed using argon-arc welding at a core of inert gases. To ensure a safe welded joint between the viprominuvach 4 and the viprominuing membrane 2 at the bottom of the container and reliable operation of the seam as a damper for the joint joints, the diameter of the beads must be greater than the diameter of the vipromine vacha d 2 by 4-10 mm, tobto. bead 6 should overlap opening 3 along the entire perimeter by at least 2 mm, and the external diameter of seam d3 should be larger than the diameter of bead 6 by 10-12 mm or equal to 5-6 mm in width. The thickness of the bead 6 is between 0.8-1.0 mm and the traditional thickness of the wall of the body 1. All dimensions are selected experimentally and the possibility of maximum transmission of ultrasonic vibrations into the core is determined, so that ovens to effectively remove deposits or scale deposits from wet surfaces.
To ensure maximum conductivity to ultrasound and the ability of the robot to transform in aggressive traces, its body is made of titanium, it is permissible to be made from stainless steel, to protect the intensity of the ultrasonic sound Due to this, the high acoustic support of stainless steel will be lower. Further, considering that the titanium braid has less acoustic support, the lower steel nut 10, which acts as a damper, the amplitude of the hammering on the vibrating surface 7 will be greater, then. Vipromine 4 operates in unilateral viprom mode, increasing the flow of acoustic energy into the area that is sounded.
With large dimensions of the container or the flexible membrane of the converter 2 on their surface, a number of converters 4 can be installed in one (Fig. 2) or a number of rows (Fig. 3). To supply electrical energy to the plastic elements of the transfer package 8, connector 12. To secure the body 1 of the switch behind the processing place for installing the cutter 13.
The ultrasonic ceramic particle converter works immediately.
When the generator supplies (not shown in the figure) electric pulses of ultrasonic frequency (20-25 kHz) through fitting 13 to the package of p'iesoelements 8, in them, under the p'ezoelectric effect, the transformation of electrical energy into energy and mechanical vibrations, such as through sound-conducting The vibrating surface 7 should be placed directly in the center, which will sound like cavitation. During the process of cavitation, there is active mixing of the sour liquid and the microbubbles in it, for which there is an increase in the adhesion forces of the pad and scales that are visible.
Viprominuvach 4 for creating a strong and uniform ultrasonic field must be expanded to a large extent, it is important that the distance between them is chosen equal to one quarter of the same time, then. /4.
All the improved design features of the reconstituted converter, as well as the intensity of the ultrasonic vibrations that are developing, are 2.4-2.7 W/cm 2 at maximum CCD, allowing for the adhesion strength of such technologically fragile devices Some of them are covered with salts or scale.
Proposals for the transformation of implementations in ultrasonic baths and the design of a sealed ultrasonic posoe-ceramic transformation device, as prepared, tested in accordance with the technical result specified in the description of the output, then. It has been confirmed that they are efficient, simple to prepare, and ensure reliable sealing of the body against leakage of the medium that is heard, and high intensity of ultrasonic vibrations.

If you look at the modifications on the resistor capacitors, they can reach a maximum of 55 Ohms.
Model with sub-winding
High-pressure generators (ultrasonic) with a sub-winding continue to vibrate with booster for the rest of the time. Such devices are actively being re-created. These types of devices work with double capacitors. The windings are twisted with a wide stitch. The clips have a diameter of 1.3 cm. The conductivity of the clips is not less than 5 microns. The frequency of the devices lies with many officials. We first check the diameter of the haircut. It is also important to note that the expanders can be used with or without pads.
Do-it-yourself viprominuvacs on the basis of a vibrator
You can make an ultrasonic vibration generator with your own hands. We prepare a neodymium magnet first. The stand is approximately 4.5 cm wide. The outline can only be installed after the haircut. It is also necessary to note that the magnet is fixed to the pad and closed with a ring.
The terminals for the device are of the conductor type. The conductivity during discharge may become close to 6 microns. Zagalny rhubarb support for viprominyuvachs of this type is traditionally more than 55 ohms. Vikorist capacitors are of different types. The middle-of-the-road fighters are selected from a small group. To install the elements, you have to quickly twist the upper part of the rod onto the swimmer. It is important not to cross the terminals.
Attachments for echo sounders
Viprominuvach (ultrasonic) for echo sounders may have poor conductivity. The diameter of the haircut in the standard model is 2.4 cm. The rings are usually of a vikorist type that is tight. Current models come with conical stands. They have a small vagina, and stench can develop in the brains of congested hair. The solenoids are made of different diameters. An insulator is screwed onto the lower part of the devices. You can purchase a premium price for the echo sounder yourself. The capacitor is therefore of the dual-channel type. If you look at the device with a cutoff of 2.2 cm, then the ground level support becomes 45 Ohm.
Modifications for radars
Viprominuvach (ultrasonic) for river radars vibrate from terminals of different conductivity. The greatest demand is for modifications with adapters and sensitivity at around 12 mV. Each device contains compact single-channel capacitors. Conductivity when set becomes 2 microns. Magnets on the frames are installed in different diameters.
Most models come with low stands. Also note that the devices are visible at high frequencies. There is a danger of bad conductivity, but in this season there is a lot of haircut. At the upper part of the winding, dry rings are installed. To increase the conductivity of the transmitter, seal the terminals with a sensitivity of 15 mV.
Models of low corrugated support
The ultrasonic viprominuvac for low-grade orthopedic surgeons now appears to be compact in size. The windings are set to 0.2 div. Magnets are installed on stands and linings. The clamps are fixed at the upper part of the device. The standard modification includes three capacitors.
It is recommended to set the heating support to a little more than 30 ohms. The capacitors of some models are of the dual-channel type. Its conductivity becomes approximately 2 microns. There are also modifications with large-diameter haircuts. The stench of vicorists is at the echo sounders. Most of the products are prepared specifically for redesigners. The clamping rings are sealed with rubber or plastic. The average diameter of the haircut in the modification is 22 cm.
Attaching a high pine support
Modifications of this type are for use, for example. Zagalny rhubarb stench conductivity reaches 4 microns. Most devices operate using contact terminals. Also note that the device is sensitive to 15 mV. The capacitors for the modification are chosen to be of the three-channel type. There are also resistor models. The stinks of the earthy rhubarb support starts at 55 ohms. The magnets on the pressure ultrasonic vibration generator are installed using the neodymium type. The average diameter of the part is 4.5 cm. The stands can be combined with pads or dry melts.
Models with unijunction capacitors
The devices of this building will ensure a conductivity of at least 5 microns. The stench is due to high sensitivity. Ultrasonic vibrators are installed with a diameter of 2 cm. The windings are formed only with rings and rubber. The lower part of the devices will have dipole terminals. When necessary, set the support to 5 Ohms. Capacitors can be installed via expansion joints. To extend low frequencies, use adapters.
If necessary, a modification to two capacitors can be made. For which terminals are installed with a conductivity of 2.2 microns. The haircut is selected to have a small diameter. It is also necessary to note that you will need a short stand made of aluminum alloy. Electrical tape is used as insulation for terminals. There are two rings attached to the upper part of the viprominyuvach. The capacitors are mounted without a center through a dipole switch. The support is not to be overestimated by 35 ohms. Sensitivity depends on the conductivity of the terminals.
