There are many types of water supply pump mechanical seals and different models, but there are five main leakage points:

(L) Seal between shaft sleeves and shafts;

(2) Seal between the dynamic ring and the shaft sleeve;

(3) Move and static ring seal;

(4) Seal between the static ring and the static ring;

(5) Seal between the sealing end cover and the pump body.

Generally speaking, the leakage between the shaft, the sealing end cover and the pump body of the shaft sleeve are more easily discovered and solved, but it is necessary to observe carefully, especially when the working medium is liquefied gases or high -pressure, toxic and harmful gases, it is relatively difficult. some.
