Hot Mechanical Seals Rotation Axis
Hxseals Industry Co.,Limited | Updated: Jun 06, 2017

Mechanical seal refers to the prevention of fluid leakage caused by at least one pair of end faces perpendicular to the axis of rotation which are retained and slid under the action of the fluid pressure and the resilient force (or magnetic force) of the compensating mechanism and the auxiliary seal Device. The elastic loading mechanism with the auxiliary seal is the metal seal of the mechanical seal we call the metal bellows seal. In the light seal, there are rubber bellows for auxiliary sealing, rubber corrugated tube elasticity is limited, generally need to supplement the spring to meet the loading elastic. "Mechanical seal" is often referred to as "machine seal".

Mechanical seal is a rotary shaft seal device. Such as centrifugal pumps, centrifuges, reactors and compressors. As the drive shaft runs through the inside and outside of the device, there is a circumferential gap between the shaft and the device, and the media in the device leaks out through the gap. If the pressure in the equipment is lower than atmospheric pressure, the air leaks into the equipment. A shaft seal that prevents leakage. Many types of shaft seals, because the mechanical seal with less leakage and long life, etc., so the world's mechanical seal is the most important shaft seal in these devices. The mechanical seal, also known as the face seal, is defined in the relevant national standard: "The end faces of at least one pair of perpendicular to the axis of rotation remain in place with the action of the fluid pressure and the resilient (or magnetic) of the compensating mechanism and the auxiliary seal A device that prevents fluid leakage from moving relative to each other.
