The basic definition and composition of Mechanical Seal

    With mechanical seal (mechanical seal) is defined by at least one pair of end faces perpendicular to the rotational axis of the fluid pressure and the compensation mechanism in the stretch (or magnetic) and the secondary seal under the action of the combination with the paste to maintain the relative sliding constituted to prevent fluid leakage of the device. Elastic Load institutions and secondary seal is metallic bellows mechanical seal we call metal bellows seal. In light seals, rubber bellows also used as an auxiliary seal, rubber bellows stretch limited, generally need to be supplemented to meet the load spring stretch. "Mechanical seal" that is often referred to as "mechanical seal"

Mechanical Seals for FGD

   Basic definitions
   Rotating mechanical seal is a mechanical seal device. Such as centrifugal pumps, centrifuges, reactors and compressors and other equipment. Through the shaft and outside the device, so that the shaft and a circumferential gap exists between the device, the device of the media leak out through the gap, if the pressure is below atmospheric pressure within the device, the internal leakage of air into the device, so there must be a seal means to prevent leakage.
   Many different types of shaft seal, due to the mechanical seal has less leakage and long life, etc., so the mechanical seal is the world's most important in these devices shaft sealing manner. Mechanical seals known seal, the national standard is defined as: "by at least one axis of rotation perpendicular to the end face of the fluid pressure and the compensation mechanism in the stretch (or magnetic) the role of the secondary seal is maintained with the combined paste constituted by the relative sliding of the device to prevent fluid leakage. "
