As the key equipment on the crushing production line, the cone crusher has a relatively long application time. In addition, it is very easy to encounter some common faults, such as unstable high-speed operation, which makes customers have to shut down for maintenance. So how did it happen?

1. Unbalanced oil supply
If the speed ratio of the cone crusher equipment achieves high-speed rotation without load, if the speed ratio is increased again, the centripetal force of the regulator fly piece will be too large, and it will get rid of the tension resistance of the variable speed spring, and the oil supply tooth The lever moves to the direction of reducing oil, and the position of the oil supply rod is very different from the position of the oil supply rack in the low gear. Therefore, if the fuel supply is uneven and the deviation is too large, it will affect the reliability of operation.

2. The time of oil cut is inconsistent
If the cone crusher equipment achieves the fuel s* speed ratio, the diesel pump should automatic y cut off the fuel. However, if the quality of the plunger pump and the oil delivery pump is uneven, or the fuel cutoff is not due to the different damage, it is very It is possible that some cylinders have been supplied with oil, and some cylinders have a sm amount of oil supply or the oil is cut off slowly. This is due to unstable transportation.

3. Poor actual operation
If the cone crusher equipment is running at high speed, if it fails to operate properly, such as the feeding equipment suddenly increases feeding, or the characteristics of the raw materials given change, the equipment is not adjusted back. As a result, the equipment appears fast and sometimes slow, and the equipment is unstable at high speed. The cone crusher equipment should be shut down immediately for inspection.
