Troubleshooting of motor failure of household crusher

troubleshooting of motor failure of household crusher adjust the toothed rod to zero division method:

1. Existing problems: there are many forage crushers on the market now, which can not only cut forage vines and tall stalks, but also crush sweet potato and corn. It is a commonly used household crusher in rural areas. With the extension of service time, the general household crusher is prone to the phenomenon that the household crusher does not start and the motor does not rotate, resulting in the inability of the crusher to work

2. Inspection method: if the proximity switch is directly loosened and the metal is not triggered, then the machine can be started to adjust the moving crossbeam. If this kind of phenomenon occurs, it can avoid the deficiencies in the spraying and electroplating process. First, we can check whether the power socket, plug and power line have oxygen, fall off and fracture. If not, we can plug in the power supply to test the machine. When the motor of the home grinder is powered on and does not rotate, and the wheel can rotate by gently pulling the wheel with your hand, It can be concluded that one of the two starting capacitors of the machine is caused by capacity failure. In this case, only new products are generally available. Another situation is that the motor does not rotate after the household crusher is powered on, and it can rotate when an external force is applied, but a weak current sound is emitted in the motor, which is caused by slight leakage of starting capacitor. If the current is too loud, the motor cannot be started at all. It is concluded that it is caused by the short circuit of the starting capacitor (the short circuit of the motor coil needs professional repair)

3. Troubleshooting: in the absence of professional instruments, remove the capacitor (4uf/400v), insert the two leads into the zero and live wire jacks of the mains power respectively to charge the capacitor, and then remove the two leads to short-circuit discharge. If discharge sparks can be emitted and there is a loud "snap" sound at this time, it indicates that the capacitor can be used; If there is a competition between spark and sound materials for cars - which kind of brake pad material has strong sound and weak sound, it indicates that the capacity of the capacitor has decreased, and it is necessary to replace it with a new one or add a small capacitor. If the capacitor is damaged and short circuited, this method cannot be used, and it must be replaced with new products of the same specification
