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
