Cone crusher is one of our common crushing equipment. We found that oil leakage may occur during the use of cone crusher. In this case, it is recommended that users do not panic. The key is to find the root cause and find the right remedy. Now let's explain the main causes of oil leakage of cone crusher. It is necessary for us to repair the problem of oil leakage or take precautions in this regard only when we understand these reasons. We should observe this during the maintenance of the machine at ordinary times to avoid problems, so as to achieve safer production and operation.

1、 What are the reasons for oil leakage of cone crusher?

1. Sealing equipment failure

During production, pay attention to check the wear of the O-ring between the transmission shaft frame and the main frame, the nylon seal ring between the oil collector and the oil slinger, and the O-ring between the oil slinger and the transmission shaft. After long-term use, some parts will be worn and deformed, lose the elasticity required for effective sealing, and the sealing device will fail, resulting in oil leakage.

2. Oil return pipe blocked

One reason why oil leakage cannot be eliminated is that the oil cannot be quickly discharged from the equipment, which will occur at low temperature. Therefore, during production, pay attention to check whether there is dirt in the main oil discharge hose or pipeline, and whether there is dirt in the long hole of the transmission shaft frame under the transmission shaft, otherwise the accumulation of dirt will hinder the flow of oil, resulting in oil leakage of the cone crusher.

3. The oil return hole of bowl tile is too small

If the oil return hole of the bowl shaped tile of the cone crusher is too small, the lubricating oil will leak out and the oil return volume is small, which can not guarantee the excellent lubrication of the large and small bevel gears. In this case, it is necessary to properly increase the oil return hole of the bowl shaped tile to ensure the oil return volume, and fundamentally solve the problems of oil leakage of the bowl shaped tile of the cone crusher and poor lubrication of the bevel gear.

4. Improper operating pressure

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 circle of the sealing cylinder.

5. Unreasonable component clearance

If the clearance 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, the lubricating oil thrown between them is easy to form an oil seal under the action of tension during the operation of the cone crusher. Driven by the air pressure, the oil seal will continuously overflow from the dust ring along the inner wall of the main engine base.

2、 How to prevent oil leakage of cone crusher?

1. Ensure excellent equipment sealing

The quality of sealing structure planning is related to the function of sealing and the life of sealing ring. The sealing function of O-ring depends on the correctness of equipment groove dimension. The groove of the sealing ring equipment is too deep, and the tightening amount of the sealing ring is impossible, so the sealing structure should be reasonably planned and processed to ensure the excellent sealing performance of the sealing equipment; Correct equipment sealing ring to ensure excellent equipment sealing. Do not use anything with edges and corners to equip the sealing ring, so as to avoid scratching the sealing ring and stretching it to the deformed position. The sealing ring can be properly lubricated for the equipment.

2. Inspection in production

Punctually check whether the filter is blocked or damaged, replace the kinked oil discharge pipeline, and ensure the smoothness of the oil return pipeline. At the same time, pay attention to cleaning the ventilation hood around the drive shaft frame of the cone crusher, and purge the long core hole on the drive shaft frame that is connected to the wind hood with compressed air; Check whether the space between the inner wall of the oil pool of the main engine base and the oil retaining ring on the counterweight body is reasonable, so as to avoid splashing the lubricating oil between them to form an oil seal, which will lead to oil leakage of the cone crusher.

3. Prevent lube oil temperature rise

The temperature rise of the lubricating oil will reduce the viscosity of the oil, accelerate the aging of the sealing elements, and then cause severe oil leakage. Therefore, we should prevent the lubricating oil temperature from rising. We can increase the heat dissipation area of the oil tank to improve the heat dissipation effect of the oil tank. If necessary, we can increase the cooling capacity below the cooler to reduce the lubricating oil temperature.
