Mechanical seal (mechanical seal) by means of at least one of the lower end surface perpendicular to the axis of rotation under fluid pressure and spring force compensation mechanism (or magnetic), and the auxiliary sealing action with combined sliding and holding paste constituted prevent fluid leakage devices. Elastic Load institutions and secondary seal is metallic bellows mechanical seal we called metal bellows seal. In light seal, as well as the use of rubber bellows secondary seal, the rubber bellows stretch limited, usually need to be supplemented to meet the load spring stretch. "Mechanical seal" that is often referred to as "mechanical seal."
The basic definition of the mechanical seal:
Mechanical seal is a seal device rotating machinery. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Due to the presence of the drive shaft through a gap between the inner and outer circumference of the device, so that the shaft and equipment, device media leak out through the gap, if the device is lower than atmospheric pressure, the air is leaking into the device, so there must be a seal means to prevent leakage. Many types of seal, leakage due to mechanical seal has less and long life, etc., so in today's world of mechanical seals in these devices is the main shaft sealing method. Mechanical seal called seal, in the relevant national standards are defined as: "by at least a pair of vertical kept under fluid pressure and compensation institutions elastic (or magnetic) and the role of co-ordination in the end face of the secondary seal affixed to the axis of rotation merger means for fluid leakage preventing relative sliding constructed.
