At present, under the requirements of production safety and environmental protection of mechanical seals, the use of mechanical seals for pumps has become more extensive, and the industrial and enterprises' dynamic equipment are mechanically sealed to ensure the static cover. leakage. Industrial pumps and chemical pumps have a wide variety of mechanical seals, and the models are different, but there are five points of the problem of leakage:
1 The seal between the bushing and the shaft;
2 Seal between the ring and the bushing;
3.Seal between the static ring;
4 seals of the static ring and the static ring;
5 sealing end caps and pump bodies.
In general, the leakage between the shaft sleeve, the leakage end cap and the pump body is relatively easy to discover and solve, but it is necessary to observe, especially when the mechanical seals is a liquefied gas or high pressure, toxic and harmful gas. It is relatively difficult. The remaining leaks are difficult to disclaimer and judging. On the basis of long-term management, maintenance practice, the symptoms of leakage can be observed and analyzed, and the correct conclusions can be obtained to properly use and repair.
