The movement of the cone crusher is driven by the eccentric sleeve driven by the bevel gear, and the clearance of the moving parts is generally large. During ore crushing, the equipment is prone to swing, Once the swing occurs, the movement track of the seal will change, and the sealing state will be damaged, resulting in leakage. There are some defects in the rubber seal of the cone crusher. Therefore, we use mechanical seal instead of rubber seal, and the use effect is good. This paper mainly introduces the advantages of mechanical seal of cone crusher.
On the sealing surface of the pebble crusher, there is a certain elastic preload attached to the friction, so that the sealing surface is under a certain pressure, and the friction surface of the sealing surface is always kept in good contact. Due to the vibration of the pebble cone crusher during operation, it can prevent the seal from deviating from its position and effectively avoid the leakage of lubricating oil.
The three-dimensional sealing surface of cone crusher only contacts in one direction, which solves the leakage defect caused by seal deformation. When the main body rotates around the eccentric sleeve, if the bearing clearance is too large, the swing amplitude will be too large, resulting in deformation of the seal and leakage. The friction auxiliary material of mechanical seal is made of oil powder in metallurgical process.
There are many small holes in this material, from which lubricating oil can seep. It has a certain lubricating effect on part of the surface and can improve the service life of the seal. The mechanical seal of the cone crusher is made of metal material, which is not deformed by external force. The sealing element is only pressed and worn in one direction, and there is no stress and deformation in the other direction, thereby improving the reliability of the seal and extending the service life of the sealing element.
