What place is relatively easy to leak mechanical seals?

The use of mechanical seals is not foolproof, it is also prone to all kinds of leaks, then appear leaks are what place? The following is to understand the detail. 1. Move. Static sealing ring, 2. Between the shaft sleeve and shaft seal, 3. Ring and the shaft sleeve, sealing between 4. Seal between the sealing cover and pump body. 5. For static ring and static ring sealing between, in general. Shaft sleeve between shaft overhang. Leakage between the sealing cover and pump body is easier to find and solve. But need to be watched carefully. Especially when working medium for liquefied gas or high pressure. When toxic or harmful gases. Relatively difficult. The rest of the leak intuitively is difficult to discern and judge. Must be in the long-term management. Based on the practice of maintenance. The leakage symptoms were observed. Analysis. Assessments. To draw correct conclusions. Looked at the above content, believe everybody already knows the part of the mechanical seal leakage easily.
