Crusher repair and maintenance work

Machinery and equipment have a life span, but this life span is also affected by a large number of human factors, for the environment also has some influence, the crusher is the same, both in the daily work process, we should pay attention to timely maintenance, good maintenance, now the market crusher models more and more, but the basic principle is the same, the failure is basically the same, now the crusher Now the crusher is prone to failure in daily life to analyze.

Crusher in daily life prone to failures and solutions are as follows:

1. The main bearing temperature is too high. May be insufficient grease, then you need to add the right amount of grease; grease pollution, then you need to clean the bearing and replace the grease; bearing damage, then you need to replace the bearing.

2. The discharge size is too large. May be excessive wear of crushing teeth, then need to replace the crushing teeth or overlay welding; side teeth wear or fall off, on replacement.

3. Crusher vibration increased. It may be bearing damage, to replace; gear coupling damage, to replace.

4. The processing capacity is reduced or the power is insufficient. Hydraulic coupling leakage, then supplement the quantitative No. 22 turbine oil or No. 6 hydraulic transmission oil, if the coupling is bad, it needs to be replaced with a new one; uneven feeding, then adjust the feeding.

5. Can not automatically reverse the rotation. Sensor installation is incorrect or damaged, adjust or replace the sensor; sensor lead or junction is loose, then connect the lead or tighten the junction.

6. Sensor protection system malfunction. The proximity switch is damaged or the wiring in the electronic control cabinet is loose, then you need to replace the add-in switch or connect the wire according to the wiring diagram.

In order to keep the crusher in good working condition, reduce the incidence of failure, improve the efficiency and prolong the service life, we must do a good job in the daily maintenance of the crusher, and must pay attention to the lubrication maintenance and bearing maintenance of the crusher equipment to prevent crusher failure.
