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
超聲波清洗機(jī)發(fā)生器上蓋打開(kāi)，分別連接換能器的正負(fù)極，確定超聲波換能器的頻率，通常超聲波換能器的頻率有20KHz、25 KHz、28 KHz、40 KHz、68 KHz等等。先用頻率計(jì)連接，確定超聲波的頻率是否一致，然后把功率電位器調(diào)節(jié)大，觀(guān)察電流是否達(dá)到核定的電流。

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.
如果開(kāi)啟后沒(méi)有達(dá)到所需要的電流，那么把超聲波發(fā)生器輸出電感螺桿松開(kāi)，擰動(dòng)電感看電流是否增大，一般的話(huà)，如有增大，那么可以提升電流增大點(diǎn)，如沒(méi)有增大而是變小，則把電感的墊片抽掉點(diǎn)看是否電流有變大。如有變大看是不是電流的大點(diǎn)調(diào)到電流的大點(diǎn)，如還是沒(méi)有達(dá)到所需要的電流，把頻率變動(dòng)一下，（換能器頻率一般調(diào)節(jié)范圍正常為正負(fù)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).
把頻率調(diào)大或調(diào)小看一下頻率變高電流變大還是頻率低電流變大。如是頻率變大電流變大，擇把頻率調(diào)節(jié)下，再提下電感看電流是否有增大，或把輸出變壓器的檔位升下檔。（如升下檔以超過(guò)清洗槽所需要的電流，則把頻率降低，好是與振子的頻率越接近越好）如已經(jīng)達(dá)到清洗槽的電流，提下電感看是否有增大（如變?。?，或抽掉一點(diǎn)墊片是否變大（如變小）。都是變小則是以調(diào)到發(fā)生器與超聲波換能器的諧正點(diǎn)和佳狀態(tài)。
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.
