The working principle of pump mechanical seal

The pump mechanical seal is mainly composed of three parts. One is the base, which must be installed on the pump body. It can be made of many materials. The other is the sliding ring, which is generally circular and rectangular in cross section. It is combined with other seals. The latter is mounted on the pump shaft, which is generally made of carbon and other materials with good wear resistance and sealing properties. The third is to have a pressure-generating compression device, which can be a spring or other means.

After the sliding ring is installed on the pump shaft, it rotates integrally with the pump shaft. The attachment part is in static contact with good sealing performance. The sliding ring is tightly pressed on the base by the pressure of the pressing device, that is to say The sliding ring rotates on the base to form a dynamic seal. Because carbonaceous materials such as graphite and pencil shavings have small molecules, are dense and have better sealing properties, and have the function of increasing lubricity, they can be realized during the rotation process. Completely sealed. However, it should be noted that during processing, the processing accuracy should be higher, and attention should be paid to the position and angle during installation. At the same time, remember not to touch the sliding contact surface with your hands when installing the mechanical seal. Even if it is an invisible fingerprint, it may be Affect the final performance.　　230.html,
