Mechanical seal refers to a device composed of at least one pair of end faces perpendicular to the rotation axis, under the action of fluid pressure and the elastic force (or magnetic force) of the compensation organization, and with the cooperation of the auxiliary seal, to maintain sticking and relative sliding to prevent fluid leakage. Tell everyone about the leakage of mechanical seal

The effect conflict pairs of the fundamental components of the mechanical seal manufacturer shall ensure a tight fit and form a sealing surface to avoid medium leakage. This requires that the pump mechanical seal should have outstanding wear resistance; The moving ring can move axially to actively compensate for the wear of the sealing surface, making it fit the stationary ring well; Static ring has floating and buffering effect. 2) Elastic elements (tension spring, bellows, barrier, etc.)

The operating pressure of the seal should be the pressure of the sealing medium in the seal chamber. Since the medium pressure in the seal chamber and the mechanical seals are not equal to the operating pressure of the pump, and sometimes the operating pressure of the seal is higher, equal to or lower than the operating pressure of the pump, the operating pressure of the seal should be determined according to the detailed pump structure and conditions. For example,

Misuse of mechanical seal manufacturer's installation steps 1. The greater the spring compression, the better the sealing effect is. In fact, too much spring compression can lead to rapid wear and instant burning of friction pairs; Excessive compression makes the spring lose the ability to adjust the end face of the moving ring, leading to seal failure. 2. The tighter the dynamic ring seal diagram is, the better. In fact, too tight the dynamic ring seal is harmful and useless. First, intensify the seal ring and shaft sleeve
