What should I do if the cone crusher leaks oil?

Cone crusher is one of the most widely used crushing equipment. The maintenance of cone crusher is also a problem that users are more concerned about. Regular maintenance can detect problems in advance and prevent problems before they occur. At the same time, it is beneficial to prolong the service life of cone crushers. In the failure of cone crusher, oil leakage is sometimes encountered. What are the reasons for this situation?

Reasons for oil leakage of cone crusher:

Failure of the sealing device

During production, it is necessary to pay attention to check the wear of the O-ring between the transmission shaft frame and the main frame, the nylon sealing ring between the oil collector and the oil slinger, and the O-ring between the oil slinger and the drive shaft. . After long-term use, these parts are subject to wear and deformation, lose the elasticity required for effective sealing, the sealing device will fail, and the equipment will leak oil.

Second, the oil return pipeline is blocked

The lubricating oil enters the lower part of the main shaft from the oil inlet pipe and rubs through the lubricating friction disc. If the working pressure of the lubrication system of the cone crusher is not suitable, the oil will be ejected from the shaft gap, resulting in the lubricating oil along the outer circle of the sealing cylinder. leak down.

Improper work pressure

The oil cannot be discharged from the equipment in time, especially when the oil temperature is low. Therefore, during production, attention should be paid to check whether there is dirt accumulated in the main oil discharge hose or pipeline, and check whether there is dirt in the long hole of the drive shaft frame under the drive shaft. Otherwise, the accumulation of dirt will hinder the flow of oil, resulting in a conical Crusher is leaking oil.

Fourth, the component clearance is unreasonable

If the gap between the inner wall of the oil pool of the main engine base and the oil retaining ring plate of the counterweight is too small, then during the working process of the cone crusher, the lubricating oil thrown between them will easily form an oil seal under the action of tension. Under the pressure of air pressure, the oil seal will continuously overflow from the dust ring along the inner wall of the main engine seat.
