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(jì)顯示正常，但高壓時(shí)沒(méi)有輸出功率。，檢查L(zhǎng)1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(jìn)行一級(jí)后向檢查，但應(yīng)該注意，由于L1后的信號(hào)分為兩個(gè)通道，一個(gè)信號(hào)異常不會(huì)影響另一個(gè)通道的工作。如果信號(hào)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(dòng)后，調(diào)整按鈕擰緊，輸出電流仍在小于2A的低端，但超聲波振動(dòng)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(qū)動(dòng)信號(hào)，這表明B6二次電源兩端的電壓是不對(duì)稱的，可以從后面一步一步地找出信號(hào)電壓或故障，另一種可能是后一級(jí)放大器有一個(gè)不工作，這可以通過(guò)測(cè)量機(jī)器工作一段時(shí)間后出口的溫度和溫度來(lái)確定。第三種現(xiàn)象較少，但并非不可能。G7和G8的陽(yáng)極電壓可能偏低，整流后的電壓較低，但熔斷器本身不會(huì)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(zāi)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(dòng)后，將調(diào)整按鈕擰緊，輸出電流低，超聲波振動(dòng)板或槽不工作。檢查發(fā)現(xiàn)所有BX7-9保險(xiǎn)絲，消除了其他故障，保險(xiǎn)絲機(jī)恢復(fù)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(huì)立即斷開，有時(shí)BX7-9會(huì)熔斷。它表明，高壓電路具有嚴(yán)重的短路，而G7和G8的相應(yīng)高壓部件的每個(gè)部件的絕緣電阻都可以用振動(dòng)計(jì)來(lái)檢查。研究發(fā)現(xiàn)，如果電阻值較低，則去除電容，并逐個(gè)進(jìn)行檢查，特別是硅堆和電子管。如果現(xiàn)場(chǎng)測(cè)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(cè)試發(fā)現(xiàn)短路及時(shí)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(jī)，正常輸出電流，正常頻率，凈帶換能器，一半產(chǎn)品不能清洗干凈。這一故障，特別是新更換超聲波振動(dòng)板后，新?lián)Q能器的安裝位置有可能不正確，應(yīng)調(diào)整上變頻器，使產(chǎn)品上端約2≤3cm，下能換熱器可靠近網(wǎng)帶，適當(dāng)調(diào)整上下?lián)Q能器的位置，相對(duì)錯(cuò)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(guān)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(yán)重短路，高壓保險(xiǎn)燒毀，這種故障可以用2500直流電千兆赫茲計(jì)進(jìn)行測(cè)試，各元件對(duì)外殼的電阻可以單獨(dú)測(cè)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(jí)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(diào)壓器和電壓表測(cè)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?gòu)?20 V左右交流電壓調(diào)整穩(wěn)壓電壓，無(wú)論三相結(jié)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.
