频率计的低电压为0.01KHZ,开机后没有输出功率。由于频率计的异常显示,可以确定G1没有开始振动,W1调整后无效。经检测和观察,调节电容C1和C2存在接触现象,电容片接触点可以分离,故障可以。
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,频率计显示正常,但高压时没有输出功率。,检查L1上的电压是否正常,以确定发生何种程度的故障,如果正常,则进行一级后向检查,但应该注意,由于L1后的信号分为两个通道,一个信号异常不会影响另一个通道的工作。如果信号在某一水平消失,则集中在电源和耦合变压器上。
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.
启动后,调整按钮拧紧,输出电流仍在小于2A的低端,但超声波振动板或槽有工作声。造成输出电流低的原因有很多,一是只有一种方式驱动信号,这表明B6二次电源两端的电压是不对称的,可以从后面一步一步地找出信号电压或故障,另一种可能是后一级放大器有一个不工作,这可以通过测量机器工作一段时间后出口的温度和温度来确定。第三种现象较少,但并非不可能。G7和G8的阳极电压可能偏低,整流后的电压较低,但熔断器本身不会熔断,以免造成更大的故障。四整流硅叠层板的输出电压低于G7和G-8电源的输出电压,这是由于四整流硅叠层板的阻尼和火灾以及BX8的熔断造成的。
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.
启动后,将调整按钮拧紧,输出电流低,超声波振动板或槽不工作。检查发现所有BX7-9保险丝,了其他故障,保险丝机恢复正常。
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,高压一旦接通,高压接触器会立即断开,有时BX7-9会熔断。它表明,高压电路具有严重的短路,而G7和G8的相应高压部件的每个部件的绝缘电阻都可以用振动计来检查。研究发现,如果电阻值较低,则去除电容,并逐个进行检查,特别是硅堆和电子管。如果现场测试,少要断开管,注意。
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,输出电流很大,但换能器不工作。这种情况可能是由于换能器短路引起的损坏,这需要检查换能器和匹配电感,测试发现短路及时更换。
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.
开机,正常输出电流,正常频率,净带换能器,一半产品不能清洗干净。这一故障,特别是新更换超声波振动板后,新换能器的安装位置有可能不正确,应调整上变频器,使产品上端约2≤3cm,下能换热器可靠近网带,适当调整上下换能器的位置,相对错开,避免超声波相互抵消。
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.
开关后烧毁高压硅堆这种失败的可能性大致有三种
There are three kinds of failure possibilities of burning high-voltage silicon stack after switching
高压电路严重短路,高压保险烧毁,这种故障可以用2500直流电千兆赫兹计进行测试,各元件对外壳的电阻可以单独测试,可以找出损坏的元件。
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.
三相升压变压器初级阶段存在短路现象,二次电压增加较大,该工具采用单相调压器和电压表测量高压,断开变压器一次和二次电压,连接电压表,注意绝缘,再从220 V左右交流电压调整稳压电压,无论三相结果是否一致。
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.
输出变压器损坏,检查故障输出变压器,并更换。
If the output transformer is damaged, check the faulty output transformer and replace it.
