Leakage is one of the common faults that occur in mechanical equipment. There are two main reasons for leakage: firstly, due to the results of mechanical processing, there are inevitably various defects and shape and size deviations on the surface of mechanical products, so gaps will inevitably occur at the joints of mechanical parts; The second is that there is a pressure difference on both sides of the seal, and the working medium leaks through the gap.
Reducing or eliminating gaps is the main way to prevent leakage. 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 small power components in the channel to cause pressure on the leakage, partially offset or completely balance with the pressure difference that causes the leakage, in order to prevent leakage.
The following is an introduction to end face seals, namely mechanical seals.
End face sealing "refers to the sealing element being pressed against another plane on the end face to seal.
Mechanical seal refers to a device that prevents fluid leakage by at least one pair of end faces perpendicular to the rotation axis, under the action of fluid pressure and compensation mechanism elasticity (or magnetic force), as well as the coordination of auxiliary seals to maintain adhesion and relative sliding. The elastic loading mechanism and auxiliary seal are mechanical seals of metal corrugated pipes, which we call metal corrugated pipe seals.
In lightweight sealing, rubber corrugated pipes are also used as auxiliary seals. Rubber corrugated pipes have limited elasticity and generally require springs to meet the loading elasticity. Mechanical seals are commonly referred to as "mechanical seals".
According to the requirements of different conditions, we can provide sealing configurations such as single end sealing, double end sealing, container sealing, lip sealing, packing sealing, special sealing, etc. made of different materials such as hard alloy, silicon carbide, graphite, etc; And according to the specific situation, configure flushing systems such as 52, 53A, 53B, 54, and 74 for users, strictly implement standards such as API682, ensure stable operation, reliable sealing, long service life, reduce operating and maintenance costs, and meet user needs.
