Vacuum degree is the important operation condition of chemical equipments. PTFE and alloy steel are two main seal methods of glass reactor manufacturers. Due to the advanced seal texture, this kind of reactor has a higher accuracy than other reactors on the market.
Mechanical seal mean the at least one pair of end face which is perpendicular to spin axis keep pasting with each other and prevent the fluid leakage. This kind of seal should act under the function of fluid pressure and compensating unit elasticity and the coordination of auxiliary seal. Among the light seal, some seal equipment uses rubber bellows as the auxiliary seal. Due to the limited elasticity of rubber, this kind of seal should be accompanied by spring to satisfy the load elasticity.
Mechanical seal is a kind of shaft seal equipment which is rotating machinery. It is always used on centrifugal pump, centrifugal machine, reactor and compressor. The transmission shaft run through the equipment so there will be a peripheral clearance between the axle and equipment. The medium in the equipment will leak through the clearance. If the internal pressure of equipment is lower than barometric pressure, air will leak into the equipment. So the shaft seal equipment is needed to prevent the leakage.
Due to the less leakage rate and long lifetime, mechanical seal become the leading method of shaft seal. In order to provide a stable operation, long lifetime and low leakage, the proper installation is very important. The first thing of installation is the affirmation of components. Before installing the mechanical seal on the machine, users should make sure the components are on deck. Bishop and flat spade are forbidden to use in the installation or disassembling of mechanical seal in order to avoid the damage of seal elements.
Mechanical seal is the mechanical component which has high accuracy. The installation process should strictly obey the standards of ministry of chemical industry.
