Sealing element

The function of the seal is to seal the gap between the joint surfaces, isolate or cut off the leakage channel, increase the resistance in the leakage channel, or add a small power element in the channel to cause pressure on the leakage, partially offset or completely balance with the pressure difference causing the leakage, so as to prevent the leakage.

According to different purposes, the seals are roughly classified as follows:

1. Classification by function: it is divided into shaft seal, hole seal, dust seal, guide ring, fixed seal and rotary seal;

2. Classification by material: rubber, polyurethane, engineering plastics, etc.

keep in storage:

1. The storage room temperature of the seal is below 30 ℃, to avoid high temperature aging of the seal;

2. The seal must be stored in the sealed package to avoid contact with the moisture or dust in the air;

3. The seal must be kept away from the strong light to prevent the seal from being eroded by ozone in the air or aging in advance.

All kinds of seals have different performance factors, such as temperature, medium, wear, pressure and so on. Common seal Name: seal ring, packing, mechanical seal, oil seal, water seal, gas seal, sealing pad, sealant, soft packing, etc.
