Analysis of the cause of failure of the cone crusher seal

Since the cone crusher is aimed at stone, due to its operating principle, many dusts are inevitably generated during operation. Therefore, a corresponding sealing device must be provided. However, sometimes the seal failure will occur. What are the reasons for the failure of the cone crusher?

Cause of damage to the seal

1, the seal is seriously worn

When the gap of the cone crusher becomes smaller, the seal is crushed and deformed and severely worn. Or when replacing some wear parts, since the replacement period of the seal is different from the wear cycle of the friction parts, the newness and the degree of the two are different, so that the sealing pressing force of the rubber sealing ring is increased, and the local deformation is lifted to cause the sealing member. damage.

2, seal aging

The rubber seal is affected by the oil quality, temperature and time factor in use, and the selection of the material for manufacturing the seal ring is improper, and the aging phenomenon is prone to occur, so that the seal ring body loses its elasticity and the sealing state changes, thereby causing the device seal to fail.

Seal deformation

1. Force deformation

When the crushing wall of the cone crusher and the crushing wall break the ore, the strong crushing force causes the body to tilt or vibrate, and the sealing member is easily deformed away from the original motion track, so that the original sealing state is changed, resulting in failure of the device seal.

2, improper installation.

When the conical crusher is installed, repaired, or replaced with a seal, the seal is partially deformed due to improper installation, resulting in failure of the equipment seal.

3, poor lubrication

Friction parts tend to have metal particles and the dust ore mixed people, as well as long-term in a high temperature environment, the lubricating oil degradation, improving the fluidity deteriorates, the resistance the seal caused by local deformation.

The above is the reason for the failure of the cone crusher seal. Users should pay attention to these small details in daily operation and reduce the failure time of the cone crusher seal.

Round Pipe High-speed Cutting Machine

Technical advantages:
1. High speed cutting of round pipe: wide processing range, diameter, 1.5G acceleration, labor saving and high efficiency.
2. Maximization ofutilization rate:tailing>40mm,one pipe can be cut into 5 lengths, and the head and tail are separated automatically
3. Customization ofleft/rightmodels: save space and turnover area, and one person can watch multiple machines
4. Independent Pipe cuttinqsystem:user-friendly and easy to operate, and remote upgrade and fault diagnosis
5. Fast loading/refuelling speed: after more than 10 years of optimization and sedimentation, the refuelling, loading and feeding are stable and efficient

6. Slag extraction component(optional):automatically remove the iron slag on the inner wall during cutting, and the inner wall is smooth and clean.

7. A6: Special for heavy-duty pipes: high-speed blanking, high rigidity, customized bed aind material rack, dura stable and high precision.

8. Excellent processing performance: it adopts high rigidity thickened bed, with bus pipe cutting system and bus motor which has faster processing speed and higher precision
