Description

Zipper head wheel axle sealing device

Technical Field

The utility model relates to the technical field of zipper head wheels, in particular to a zipper head wheel shaft seal device.

Background

The mechanical seal is a device for preventing fluid leakage, which is formed by at least one pair of end faces perpendicular to the rotation axis and keeping fit and relatively sliding under the action of fluid pressure and the elastic force of a compensation mechanism and the cooperation of an auxiliary seal, and the elastic loading mechanism and the auxiliary seal are mechanical seals of a metal corrugated pipe, which is called as a metal corrugated pipe seal. In light seals, rubber bellows are also used as auxiliary seals, the rubber bellows has limited elasticity, and a spring is generally required to be assisted to meet the loading elasticity. The mechanical seal is a shaft seal device of a rotary machine. Such as centrifugal pumps, centrifuges, etc. Since the drive shaft extends through the device and is thus located inside and outside the device, there is a circumferential gap between the shaft and the device through which the medium in the device leaks outwards, and if the pressure in the device is below atmospheric pressure, air leaks into the device, so that a shaft seal means for preventing leakage is necessary. Shaft seals are of many kinds, and mechanical seals are the most important shaft sealing means in these devices in the world because of their advantages such as small leakage and long life.
