The easiest way to detect the cause of seal leakage
Oct 03, 2021
It is very simple to use the simplest method to detect the leakage of seals. First of all, we have to know the seals well, and how much can you know about the selection of seals. If you know your seal products well, I think you have become professional. Stop talking nonsense, let's get to the point. Let's talk about the installation of the seal first, and then talk about the problems encountered in the selection of the seal.
1. Installation problems
Incorrect installation direction of the seal causes leakage.
During installation, foreign matter or dust in the pipeline enters the sealed cavity and causes leakage.
Poor assembly causes damage to the seals and leaks.
Scratches on the surface of the seal cause leakage.
The piston rod is not concentric, and the eccentric load causes leakage.
2. the selection of seals
The pressure is too high and the hardness of the seal is too small to be squeezed out of the metal groove.
The sealing material and the medium are compatible, and the seals is softened or dissolved.
The seal is used in conditions where the temperature is too high, and the seal material is carbonized.
The low temperature causes the sealing material to harden and shrink and cause leakage.
The use of the line speed is too high, causing the seal to heat up, dry grinding, carbonization, then leakage.
Poor lubrication in operating conditions causes seals to wear and leak.
The cavity in use is exposed to vibrations causing leakage.
Leakage caused by seal wear caused by dust.
The hardness of the seal is too high to completely fill the metal groove to cause leakage.
The size of the seal does not match the metal groove causing leakage.
Use seals that have been stored for a long time and are aged to cause leakage.
