What is the mechanical seal chamber of a pump related to?
Thread Content
For the pump on site, is the internal or external leakage of the mechanical seal caused by high temperature deformation of the seal? Is there a specific reason for the cooling water issue with our mechanical seal?
For double-end face mechanical seals, you need to ensure that the material used is suitable and that the design is reasonable On-site operating conditions.
Check whether the cooling water is flowing properly, as well as the degree of scaling in the cooling chamber of the mechanical seal; high temperatures can cause damage to the mechanical seal!
It is related to factors such as improper assembly of the mechanical seal, particles in the medium, high medium temperature, interruption of cooling water for the mechanical seal, and long operating time of the air pump.
Medium temperature, interruption of cooling water supply~~~ High temperature causes deformation of the mechanical seal, leading to particles that enter the contact surface between the rotating and stationary rings, thereby affecting the sealing performance. In air pumps, all mechanical energy is converted into internal energy, which results in high temperature and deformation; improper assembly as well as misalignment can also cause issues Unbalanced forces. Is this understanding correct? ?
Improper assembly refers to the spring being either too tight or too loose, an offset between the moving ring and the stationary ring, as well as the end surfaces not being dried properly during assembly.
The mechanical seal has five sealing points; be sure to fill it and remove all gas before starting the pump! Supply cooling water and buffer before starting the pump!
There are too many various reasons for seal leakage; it is necessary to base the analysis on an understanding of the original information and the equipment, as well as on the symptoms of leakage observed on site. It’s similar to going to the hospital for treatment. This is just my personal understanding; if there are any mistakes, I hope fellow netizens will kindly point them out.
Check whether there is scaling or blockage in the machine seal box, and whether the cooling water flow is unobstructed
If there is a leak, remove it and check to determine where the problem lies; analyze the root cause of the mechanical seal failure. There are several common reasons for seal leakage, but it is necessary to analyze each specific case individually in order to come up with appropriate solutions.
