Small knowledge of sealing:

Leakage is one of the common failures of mechanical equipment. There are two main reasons for the leakage:

(1) As a result of mechanical processing, there must be various defects and shape and size deviations on the surface of mechanical products, so gaps will inevitably occur at the joints of mechanical parts;

(2) There is a pressure difference on both sides of the seal, and the working medium will leak through the gap.

Reducing or eliminating gaps is the main way to prevent leaks. The function of sealing is to seal the gap between the joint surfaces, isolate or cut off the leakage channel, increase the resistance in the leakage channel, or add a small working element in the channel to cause pressure on the leakage, and partially offset the pressure difference causing the leakage. Or fully balanced to stop leaks.
