The quality inspection process of the mechanical seal manufacturer The mechanical seal is a sealing device composed of two sealing elements (static ring and dynamic ring) perpendicular to the shaft, smooth and straight surfaces that fit each other and rotate relative to each other. The pressure of sealing medium is used to generate appropriate pressing force on the contact surface (end face) of rotating rotating rotating ring and stationary ring, so that the two end faces can be closely combined and a layer is maintained between the end faces

The mistake of mechanical seal manufacturer's installation steps is not true. Excessive 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. One is to intensify the wear between the seal ring and the shaft sleeve, causing premature leakage; Second, it's a big move
