Spring Mechanical Shaft Seal for Pump

The mechanical seal is defined by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or force) the role of the device and auxiliary seal with maintaining relative sliding postmerger and constitutes to prevent fluid leakage. Elastic loading mechanism and auxiliary seal is the mechanical seal of metal corrugated pipe. In the light seal, as well as the use of rubber bellows as an auxiliary seal, rubber bellows elastic limited, generally need to be used to meet the spring loaded with elastic
 
Mechanical seal is the seal device for rotary machines. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Due to the drive shaft through the inside and outside of the equipment, so there is a gap between the shaft and the peripheral equipment, equipment in the media leak out through the gap, if the device internal pressure below atmospheric pressure, air leakage to the equipment, so there must be a package of the shaft to prevent leakage. Many kinds of seal, mechanical seal has advantages because of less leakage and long life, so the mechanical seal is sealed in the main shaft of the equipment. The mechanical seal is also called  seal, in the relevant national standard is defined as: "by at least a pair of end faces perpendicular to the axis of rotation of the fluid pressure and the elasticity of compensation organizations (or magnetic) device and the role of the coordination of auxiliary seals to keep up with the relative sliding to prevent fluid leakage."
