Usually check and repair from the following three aspects:
1. First check the power socket, plug, power cord for oxygen-free fall-off, breakage, if not, plug in the power test machine.
2. When the motor is energized and does not rotate, and the wheel can be rotated by hand, it can be concluded that one of the two starting capacitors of the machine has a capacity failure. In this case, only new products are generally exchanged.
3. In another case, the power is not rotated, and the external force can be rotated but a weak current is emitted in the motor, which is caused by a slight leakage of the starting capacitor. If the current is too loud, the motor will not start at all, and it is determined that the starting capacitor is short-circuited (the motor coil is short-circuited and needs professional repair). In the absence of professional equipment, the capacitor (4UF/400V) can be removed first, and the two leads are respectively inserted into the zero and fire line jacks of the mains to charge the capacitor, and then the two leads are short-circuited and discharged. If the discharge spark can be emitted at this time and there is a loud "beep" sound, the capacitor can be used; if the spark and the sound are weak, the capacity of the capacitor has dropped, and it is necessary to replace it or add a small capacitor. If the capacitor of the universal crusher has been damaged, the method cannot be used, and it must be replaced with a new product of the same specification.
The above points are all relatively easy to check and maintain. Under the premise of ensuring the normal operation of the equipment, we can solve it ourselves.
Self-maintenance inspection of universal crusher
In the daily use of equipment such as universal crusher, coarse crusher, and micro-grinder, some small problems can generally be checked and maintained by themselves, and manufacturers are not required to save time and improve production efficiency.
