超声波发生器发出的高频振荡信号，通过换能器转换成高频机械振荡而传播到介质－－清洗溶剂中，超声波在清洗液中疏密相间的向前辐射，使液体流动而产生数以万计的直径为50-500μm 的微小气泡，存在于液体中的微小气泡在声场的作用下振动。这些气泡在超声波纵向传播的负压区形成、生长，而在正压区，当声压达到一定值时，气泡迅速增大，然后突然闭合。并在气泡闭合时产生冲击波，在其周围产生上千个大气压，破坏不溶性污物而使他们分散于清洗液中，当团体粒子被油污裹着而黏附在清洗件表面时，油被乳化，固体粒子及脱离，从而达到清洗件净化的目的
The high-frequency oscillation signal sent out by the ultrasonic generator is converted into high-frequency mechanical oscillation through the transducer and propagated to the medium cleaning solvent. The forward radiation of ultrasonic in the cleaning solution makes the liquid flow and generates tens of thousands of 50-500 diameters μ M, the tiny bubbles in liquid vibrate under the action of sound field. These bubbles form and grow in the negative pressure area of ultrasonic longitudinal propagation, while in the positive pressure area, when the sound pressure reaches a certain value, the bubbles rapidly increase and then suddenly close. The shock wave will be generated when the bubble is closed, and thousands of atmospheres will be generated around it to destroy the insoluble dirt and make them disperse in the cleaning solution. When the group particles are wrapped in oil stains and adhere to the surface of the cleaning part, the oil will be emulsified, and the solid particles will be separated, so as to achieve the purpose of cleaning the parts
超声波清洗机发生器上盖打开，分别连接换能器的正负极，确定超声波换能器的频率，通常超声波换能器的频率有20KHz、25 KHz、28 KHz、40 KHz、68 KHz等等。先用频率计连接，确定超声波的频率是否一致，然后把功率电位器调节大，观察电流是否达到核定的电流。

The upper cover of the ultrasonic cleaner generator is opened, and the positive and negative poles of the transducer are respectively connected to determine the frequency of the ultrasonic transducer. Generally, the frequency of the ultrasonic transducer is 20KHz, 25 KHz, 28 KHz, 40 KHz, 68 KHz, etc. First connect with a frequency meter to determine whether the ultrasonic frequency is consistent, then adjust the power potentiometer to the maximum and observe whether the current reaches the approved current.
如果开启后没有达到所需要的电流，那么把超声波发生器输出电感螺杆松开，拧动电感看电流是否增大，一般的话，如有增大，那么可以提升电流增大点，如没有增大而是变小，则把电感的垫片抽掉点看是否电流有变大。如有变大看是不是电流的大点调到电流的大点，如还是没有达到所需要的电流，把频率变动一下，（换能器频率一般调节范围正常为正负1KHz）。
If the required current is not reached after opening, loosen the screw of the output inductance of the ultrasonic generator, twist the inductance to see if the current increases. Generally, if it increases, the current increase point can be raised. If it does not increase but decreases, remove the gasket of the inductance to see if the current increases. If there is any increase, it is necessary to adjust the maximum current point to the maximum current point. If the required current is still not reached, change the frequency (the frequency of the transducer is normally adjusted within the range of plus or minus 1KHz).
把频率调大或调小看一下频率变高电流变大还是频率低电流变大。如是频率变大电流变大，择把频率调节下，再提下电感看电流是否有增大，或把输出变压器的档位升下档。（如升下档以超过清洗槽所需要的电流，则把频率降低，好是与振子的频率越接近越好）如已经达到清洗槽的电流，提下电感看是否有增大（如变小），或抽掉一点垫片是否变大（如变小）。都是变小则是以调到发生器与超声波换能器的谐正点和佳状态。
Turn the frequency up or down to see whether the frequency becomes higher, the current becomes greater, or the frequency becomes lower, the current becomes greater. If the frequency increases and the current increases, adjust the frequency and then lift the inductance to see if the current increases, or move the output transformer up to the next gear. (If the current required by the cleaning tank is exceeded by shifting up and down, reduce the frequency, preferably as close as possible to the frequency of the vibrator.) If the current of the cleaning tank has been reached, lift the inductance to see if it increases (if it decreases), or remove a little gasket to see if it increases (if it decreases). If it is smaller, it will be adjusted to the harmonic point and optimal state of the generator and ultrasonic transducer.
