Repair and maintenance work of the crusher machine

Mechanical equipment has a life span, but this life span is also affected by a large number of human factors. The crusher machine is also the same for the environment. Whether in the daily work, we must pay attention to timely maintenance. Good maintenance, now there are more and more crusher models on the market, but the basic principles are the same, and the faults are basically the same, which will analyze the faults that are easy to occur in the daily life of the crusher machine.

The faults and solutions that the crusher machine is prone to in daily life are as follows:

  • 1. The main bearing temperature is too high. It may be that the grease is insufficient, then you need to add the right amount of grease; if the grease is contaminated, you need to replace the grease after cleaning the bearing; if the bearing is damaged, you need to replace the bearing.
  • 2. The discharge size is too large. It may be that the broken teeth are excessively worn, then the broken teeth need to be replaced or surfacing; if the teeth are worn or detached, they are replaced.
  • 3. The vibration of the crusher machine is increased. It may be that the bearing is damaged and replaced; the gear coupling is damaged and replaced;

  • 4. Reduced processing power or insufficient power. If the hydraulic coupler leaks, then the quantitative No. 22 turbine oil or No. 6 hydraulic transmission oil is added. If the coupler is broken, it needs to be replaced. If the feed is not uniform, adjust the feed.
  • 5. Can not be automatically reversed. If the sensor is not properly installed or damaged, adjust or replace the sensor; if the sensor leads or wiring are loose, turn on the lead or tighten the wiring.
  • 6. The sensor protection system is out of order. If the proximity switch is damaged or the wiring inside the electric control cabinet is loose, then you need to replace the add-in switch or connect the line according to the wiring diagram.

In order to keep the crusher machine in good working condition, reduce the failure rate, improve work efficiency and prolong the service life, we need to do the daily maintenance work of the crusher.Pay attention to the lubrication maintenance and bearing maintenance of the crusher equipment. The crusher machine "strikes".
