　　In fact, the multi-cylinder hydraulic cone crusher means that there are multiple hydraulic cylinders distributed around the circumference of the frame. This structure can realize the connection of the upper and lower frames during the crushing process, as well as the retreat protection of unbreakable objects and the cavity cleaning function of sudden shutdown. The hydraulic cylinder for cleaning the crushing cavity has a long stroke and has nothing to do with the wear of the lining plate, which can reduce the workload of cleaning and can quickly clear the cavity, thereby shortening the downtime. Compared with the single-cylinder hydraulic cone crusher, it is not necessary to dismantle the upper and lower The connecting bolts of the frame can be easily adjusted to the upper frame, which is labor-saving and convenient.

　　Cone crusher is one of the widely used crushing equipment, and the maintenance of cone crusher is also a concern of users. Regular maintenance can detect problems in advance, prevent problems before they occur, and at the same time help prolong the service life of cone crushers. Discuss the oil leakage problem of cone crusher.

　　One of the reasons for the oil leakage of the cone crusher is the failure of the sealing device. During production, 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. . Because these parts will be worn out and deformed after long-term use, lose the elasticity required for sealing, and the sealing device will fail, which will lead to the problem of equipment oil leakage.

　　One of the reasons for oil leakage of cone crusher is improper working pressure. Oil leaks can also be caused by oil not draining quickly from the equipment, especi y when the oil temperature is low. Therefore, in 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 the cone crusher. Oil spill.

　　One of the reasons for the oil leakage of the cone crusher is the blockage of the oil return pipeline. The lubricating oil enters the lower part of the main shaft from the oil inlet pipe and is rubbed by the lubricating friction disc. If the working pressure of the lubrication system of the cone crusher is improper, the oil will be ejected from the shaft gap, causing the lubricating oil to leak down along the outer circumference of the sealing cylinder.

　　One of the reasons for oil leakage of cone crusher is unreasonable component clearance. If the gap between the inner w of the oil pool of the main engine base and the oil retaining ring plate of the counterweight is too sm , 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 push of air pressure, the oil seal will continuously overflow from the dust ring along the inner w of the main frame.
