There are many pulverizers on the market. It can cut the feed vines, high stalks, and smash red sorghum and corn. It is a common machine in rural areas. With the extension of the use time, the following faults often occur: the work is weak when crushing; it does not start; it is not energized. Under normal circumstances, you can repair it yourself.
First check the power socket, plug, power cord for aerobic fall-off, breakage, if not, you can plug in the power test machine, when the motor is energized and does not rotate, when you turn the wheel and turn it by hand, you can conclude that One of the two starting capacitors of the machine has a capacity failure. In this case, only new products are generally exchanged. In another case, the power is not rotated, and an external force can be applied to rotate 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. This method cannot be used if the capacitor has been damaged and short-circuited, and must be replaced with a new product of the same specification.
There is another type of rod grinding high-speed pulverizer. The general quality of this pulverizer is not easy to damage, and the daily maintenance is more important. The following is the maintenance focus of this type of pulverizer. Check that the lubrication of the bearing is good. Check that all fasteners are tight. Check that the drive belt is installed correctly and in good condition. If the belt is damaged, it should be replaced in time. When there is oil on the belt or the sheave, clean it with a clean rag. Check if the guard is good. If the guard is found to be unsafe, it should be removed in time. Check for any material or other debris in the damaged cavity. If it should be cleaned at times. Check if the hydraulic overhead machine head or the top threaded rod is retracted and adjust the gasket to be installed correctly and tightly.
The pulverizer is a kind of agricultural machinery which is more commonly used. The fan on the pulverizer is in the working process. Because the rotation speed is very high, the working environment is bad, the sealing is not strict, the sand causes serious wear on the wind opportunity, and the impeller body and the hub rivet The head falls off and fatigue cracks appear at the rivet holes. How to repair the fan has become a thorny problem. The slightest maintenance method can not only achieve the purpose of repair, but also make the fan completely scrapped.
