      Product details:
      Mechanical seal for container type, single face, spring, built-in bearings, balance type mechanical seal, suitable for all kinds of weak corrosive medium, often used in the lateral mixing condition, selection of hard to hard to match with friction pair group rinse mouth, can also be used in mud and other conditions.
      Mechanical seal is to point to by at least a pair of end face perpendicular to the rotation axis in fluid pressure and compensating unit elasticity (or magnetic force) under the action of and with the cooperation of the auxiliary seal up keep post merger relative sliding and prevent fluid leak device. The elastic loading mechanism and the auxiliary seal are the mechanical seals of the gold property lines. We are called the metal bellows seal. In light seal, the rubber bellows are used as auxiliary seals, and the rubber corrugated pipe is limited in elasticity. It is usually required to support the loading spring with a spring.
      Mechanical seal is a rotary mechanical shaft sealing device. Such as centrifugal pump, centrifuge, reactor and compressor. Due to the drive shaft through both inside and outside the equipment, in this way, a circumferential clearance between shaft and equipment, equipment of medium leak out through the gap, if the device internal pressure is below atmospheric pressure, leakage in the air to the equipment, so there must be one to prevent leakage of the shaft sealing device. There are many kinds of shaft seals, because mechanical seal has the advantages of little leakage and long life, so mechanical seal is the most important shaft seal in the world today.
