Analysis of Oil Leakage of Cone Crusher

Reasons for oil leakage of cone crusher
1. Sealing equipment failure: In production, pay attention to check the O-ring seal between the transmission shaft frame and the main frame, the nylon seal ring between the oil collector and the oil slinger, and the O between the oil slinger and the drive shaft. The wear condition of the ring-shaped seal ring, because these parts will be worn and deformed after long-term use, and lose the elasticity required for effective sealing, and the failure of the sealing device will cause the problem of oil leakage.

2. The oil return pipeline is blocked: The oil leakage may also be caused by the oil not being quickly discharged from the equipment, especially when the oil temperature is low. Therefore, during production, pay attention to check whether there is accumulation in the main oil discharge hose or pipeline Loot, check whether there is loot in the long hole of the drive shaft frame under the drive shaft, otherwise the accumulation of loot will hinder the movement of oil, and then cause the cone crusher to leak oil.

3. The oil return hole of the bowl-shaped bush is too small: If the oil return hole of the bowl-shaped bush of the cone crusher is too small, the lubricating oil will leak out and the oil return is small, which cannot guarantee the *lubrication of the large and small bevel gears. In this case, the bowl-shaped bushing oil return hole should be appropriately enlarged to ensure the amount of oil return, and fundamentally solve the problem of oil leakage of the bowl-shaped bushing of the cone crusher and poor lubrication of the bevel gear.

4. Improper working pressure: Lubricating oil enters the lower part of the main shaft from the oil inlet pipe and conflicts with the lubrication conflict disc. If the working pressure of the lubrication system of the cone crusher is improper, the oil will be ejected from the axial gap, causing the lubricating oil to follow the outer circle of the sealing cylinder. Leak down.

5. Unreasonable space for components: If the space between the inner wall of the oil sump of the main engine seat and the oil baffle plate of the counterweight is too small, the lubricating oil thrown between them will be easily affected by tension during the working process of the cone crusher. Form an oil seal. The oil seal will continuously overflow from the dust ring along the inner wall of the main base under the air pressure.

How to prevent oil leakage of cone crusher
1. Ensure *equipment sealing: The quality of the sealing structure planning is related to the function of the seal and the life of the sealing ring. The sealing function of the O-ring seal depends on the correctness of the equipment groove size. The sealing ring equipment groove is too deep, and the sealing ring shrinkage is not enough to achieve a sealing effect. Therefore, the sealing structure should be planned and processed reasonably to ensure the sealing * of the sealing equipment; the correct equipment sealing ring can ensure the *sealing of the equipment. Do not use angular tools and equipment to avoid scratching the sealing ring and avoid stretching it to a deformed position. The lubricating oil can be changed to the seal ring to facilitate the equipment.

2. Inspection during production: regularly check whether the filter is blocked or damaged, and replace the already kinked oil drain line to ensure the smoothness of the oil return line. At the same time, pay attention to cleaning the ventilation hood beside the drive shaft frame of the cone crusher, and use compressed air to purge the long core hole connected to the ventilation hood on the drive shaft frame; check the space between the inner wall of the oil sump of the main base and the oil baffle on the counterweight body Is it reasonable to avoid the lubricating oil splashing between each other to form an oil seal, and then cause the cone crusher to leak oil.

3. S* lubricating oil temperature rise: The lubricating oil temperature rises simply reduces the viscosity of the oil, accelerates the aging of the sealing element, and then causes severe oil leakage. Therefore, we should prevent the lubricating oil temperature from rising. The heat dissipation area of ​​the fuel tank can be added to improve the heat dissipation of the fuel tank. If necessary, a cooler can be added to lower the lubricating oil temperature.
