The low voltage of the frequency meter is 0.01khz, and there is no output power after startup. Due to the abnormal display of the frequency meter, it can be determined that G1 does not start vibration and W1 is invalid after adjustment. Through detection and observation, the regulating capacitors C1 and C2 are in contact, the contact points of the capacitor can be separated, and the fault can be eliminated.

接通后，頻率計顯示正常，但高壓時沒有輸出功率。，檢查L1上的電壓是否正常，以確定發(fā)生何種程度的故障，如果正常，則進行一級后向檢查，但應該注意，由于L1后的信號分為兩個通道，一個信號異常不會影響另一個通道的工作。如果信號在某一水平消失，則集中在電源和耦合變壓器上。

After switching on, the frequency meter displays normally, but there is no output power at high voltage. First, check whether the voltage on L1 is normal to determine the degree of fault. If it is normal, conduct a level-1 backward check. However, it should be noted that since the signal after L1 is divided into two channels, one signal abnormality will not affect the operation of the other channel. If the signal disappears at a certain level, it is concentrated on the power supply and coupling transformer.

啟動后，調整按鈕擰緊，輸出電流仍在小于2A的低端，但超聲波振動板或槽有工作聲。造成輸出電流低的原因有很多，一是只有一種方式驅動信號，這表明B6二次電源兩端的電壓是不對稱的，可以從后面一步一步地找出信號電壓或故障，另一種可能是后一級放大器有一個不工作，這可以通過測量機器工作一段時間后出口的溫度和溫度來確定。第三種現(xiàn)象較少，但并非不可能。G7和G8的陽極電壓可能偏低，整流后的電壓較低，但熔斷器本身不會熔斷，以免造成更大的故障。四整流硅疊層板的輸出電壓低于G7和G-8電源的輸出電壓，這是由于四整流硅疊層板的阻尼和火災以及BX8的熔斷造成的。

After starting, the adjusting button is tightened, and the output current is still at the low end less than 2A, but the ultrasonic vibration board or groove has working sound. There are many reasons for the low output current. One is that there is only one way to drive the signal, which indicates that the voltage at both ends of B6 secondary power supply is asymmetric, and the signal voltage or fault can be found step by step from the back. Another possibility is that one of the last stage amplifiers does not work, which can be determined by measuring the outlet temperature and temperature after the machine works for a period of time. The third phenomenon is less, but not impossible. The anode voltage of G7 and G8 may be low, and the voltage after rectification is low, but the fuse itself will not fuse, so as not to cause greater failure. The output voltage of four rectifier silicon laminate is lower than that of G7 and G-8 power supply, which is caused by the damping and fire of four rectifier silicon laminate and the fusing of bx8.

啟動后，將調整按鈕擰緊，輸出電流低，超聲波振動板或槽不工作。檢查發(fā)現(xiàn)所有BX7-9保險絲，消除了其他故障，保險絲機恢復正常。

After startup, tighten the adjustment button, the output current is low, and the ultrasonic vibrating plate or groove does not work. All bx7-9 fuses were found, other faults were eliminated, and the fuse machine returned to normal.

故障是，高壓一旦接通，高壓接觸器就會立即斷開，有時BX7-9會熔斷。它表明，高壓電路具有嚴重的短路，而G7和G8的相應高壓部件的每個部件的絕緣電阻都可以用振動計來檢查。研究發(fā)現(xiàn)，如果電阻值較低，則去除電容，并逐個進行檢查，特別是硅堆和電子管。如果現(xiàn)場測試，至少要斷開管，注意安全。

The fault is that once the high voltage is connected, the high voltage contactor will be disconnected immediately, and sometimes bx7-9 will fuse. It shows that the high-voltage circuit has a serious short circuit, and the insulation resistance of each component of the corresponding high-voltage components of G7 and G8 can be checked with a vibrometer. It is found that if the resistance value is low, first remove the capacitance and check it one by one, especially the silicon stack and electron tube. In case of field test, at least disconnect the pipe and pay attention to safety.

接通后，輸出電流很大，但換能器不工作。這種情況可能是由于換能器短路引起的損壞，這就需要檢查換能器和匹配電感，測試發(fā)現(xiàn)短路及時更換。

After switching on, the output current is large, but the transducer does not work. This situation may be due to the damage caused by the short circuit of the transducer, so it is necessary to check the transducer and matching inductance, and replace it in time if the short circuit is found in the test.

開機，正常輸出電流，正常頻率，凈帶換能器，一半產品不能清洗干凈。這一故障，特別是新更換超聲波振動板后，新?lián)Q能器的安裝位置有可能不正確，應調整上變頻器，使產品上端約2≤3cm，下能換熱器可靠近網帶，適當調整上下?lián)Q能器的位置，相對錯開，避免超聲波相互抵消。

Start up, normal output current, normal frequency, clean belt transducer, half of the products can not be cleaned. This fault, especially after the replacement of the ultrasonic vibrating plate, the installation position of the new transducer may be incorrect. Adjust the up converter so that the upper end of the product is about 2 ≤ 3cm, and the lower energy heat exchanger can be close to the mesh belt. Properly adjust the position of the upper and lower transducers and stagger them to avoid mutual cancellation of ultrasonic waves.

開關后燒毀高壓硅堆這種失敗的可能性大致有三種

There are three kinds of failure possibilities of burning high-voltage silicon stack after switching

高壓電路嚴重短路，高壓保險燒毀，這種故障可以用2500直流電千兆赫茲計進行測試，各元件對外殼的電阻可以單獨測試，可以找出損壞的元件。

The high-voltage circuit is seriously short circuited and the high-voltage fuse is burned. This fault can be tested with 2500 DC gigahertz meter. The resistance of each element to the shell can be tested separately to find out the damaged element.

三相升壓變壓器初級階段存在短路現(xiàn)象，二次電壓增加較大，該工具采用單相調壓器和電壓表測量高壓，斷開變壓器一次和二次電壓，連接電壓表，注意絕緣，再從220 V左右交流電壓調整穩(wěn)壓電壓，無論三相結果是否一致。

There is a short circuit phenomenon in the primary stage of the three-phase step-up transformer, and the secondary voltage increases greatly. The tool uses a single-phase voltage regulator and voltmeter to measure the high voltage, disconnect the primary and secondary voltage of the transformer, connect the voltmeter, pay attention to insulation, and then adjust the regulated voltage from the AC voltage of about 220 V, regardless of whether the three-phase results are consistent or not.

輸出變壓器損壞，檢查故障輸出變壓器，并更換。

If the output transformer is damaged, check the faulty output transformer and replace it.
