The working principle and application of mechanical seal

　2016-12-05　　

Mechanical sealing technology has a history of many years. According to different working principles, mechanical sealing technology can be divided into static sealing and dynamic sealing.

The static seal of the mechanical seal refers to the seal between the joint surfaces of two relatively static parts; the dynamic seal of the mechanical seal refers to the sealing technology between the joint surfaces of two relatively moving parts.

Mechanical seal, as a kind of rotating shaft dynamic seal, is an important part to prevent leakage, save energy, and control environmental pollution in the produced mechanical equipment. In the past ten years, mechanical seal technology has developed greatly and has been widely used in the fields of electric power, shipbuilding, aerospace, and petrochemical industry. According to statistics from the petrochemical industry, 80% to 90% of centrifugal pumps use mechanical seals. In industrially developed countries, in the sealing devices of rotating machinery, the amount of mechanical seals accounts for more than 90% of all seals in use. At present, mechanical seal has become the most important form of dynamic seal in fluid sealing technology.　　180.html,
