The hydraulic cone crusher, as the name suggests, adopts a hydraulic protection system. The hydraulic cylinder is located at the lowest part of the equipment. It is used to support the weight of the cone crusher and at the same time bear the force of crushing the ore. Therefore, the system oil pressure is constantly changing, sometimes There will be hydraulic oil leakage problems, let's see below which reasons may cause oil leakage.

1. The oil pressure of the system is constantly changing, and these changes all produce forces acting on the hydraulic steel pipes, flanges and bolts. The long-term change of external force causes the bolts between the hydraulic cylinder flange and the steel pipe flange to loosen, causing separation and leakage of hydraulic oil.

2. The steel pipe and the flange are connected together by welding, and the force generated by the change of oil pressure will also cause the welding place to be continuously impacted and break.

3. During the operation, the ore continuously collided with the hydraulic steel pipe due to the *er impact force, which caused the steel pipe to be damaged and oil leakage occurred.
Through analysis, we know that the main cause of oil leakage is that steel pipes, flanges and bolts receive force and are damaged. Therefore, it can be solved by increasing the strength of steel pipes and flanges and extending the service life of bolts.
