seal leakage influence

It is important to choose the right seal and sealing material. Therefore, in order to better prevent seal leakage and avoid repeated problems, NingBo CL Sealing Co., Ltd. tells you the four major influences and details of the seal leakage.

*First aspect: installation issues

1. The seal is installed in the wrong direction;
2. Poor assembly process, resulting in damage to the seals;
3. Sealing pipes to accumulate foreign matter (dust);
4. There are scratches on the surface of the sealing rod;
5. The concentricity is not correct, causing an offset;
6. The processing is not proper and the paint enters the seal.

*Second aspect: sealing selection problem

1. Deformation, deterioration and simplification of the seal material caused by high temperature conditions;
2. The seal material appears in the media incompatible condition, causing the expansion reaction;
3. After the air is mixed into the equipment, the adiabatic compression causes the seal to burn;
4. The amount of pressure during the work process is too high, and biting occurs in the gap;
5. The seal is subjected to external shock during operation, causing leakage;
6. Lubrication is not in place to form seal wear and wear;
7. The low temperature condition causes the seal material to harden and shrink;
8. At low pressure and low speed, the parts of the equipment are not moving smoothly.
9. Leakage caused by rust in the seal groove.

*Third aspect: seal assembly design problem

1. The support ring is not properly selected and the cylinder is damaged;
2. The friction pair clearance is not suitable;
3. Thread chamfering is not appropriate;
4. The sliding surface is rough, wear seals and parts;
5. Poor stiffness and movement;
6. Leakage of the piston and piston rod plating holes;
7. Poor lubrication causes wear and tear, bite the cylinder and piston rod.

* Fourth aspect: custody issues
1. The transportation process deteriorates due to high temperature for a long time;
2. Strong sunlight ozone, radiation causes deterioration of sealing materials;
3. Lack of proper preservation methods to deform the seal specifications;
4. The sealing member is stored for too long, and the sealing material is prone to deterioration.
