Machine seal problem
Thread Content
After replacing the new machine seal and running it for about 2 hours, it became like this. This is true for two consecutive times. (The original machine has been running for about 6 months with no problems). The on-site operation said there was no problem with the operation, and the outlet pressure was about 5 kg (head 50).
Are the original seal and the new seal made by the same manufacturer and model? Determine how the seat deformation occurs. Is there any problem installing concentric.
For this type of mechanical seal, the quality of products on the market varies greatly. Especially in the selection of PTFE materials
WB2 has an external mechanical seal, so you are not buying an original accessory, right?
1. Pump evacuation； 2. The compression amount is not adjusted properly. ； It is recommended that technicians from the mechanical seal manufacturer be invited to the site for joint analysis. Only by seeking truth from facts can the real cause be analyzed.
The value of this mechanical seal is very low. The cost is about a hundred yuan. One set of mechanical seals is not enough for the fare: lol It may be difficult to call the mechanical seal manufacturer. . .
This is the first time I have seen such a mechanical seal. Simply say, don’t follow me.
There may be problems with the design and production. The elasticity may be too high, and the material of the PTFE bellows may be too thin in certain places during design and production, causing the bellows to tear! This structure has no transmission pins and relies entirely on PTFE bellows to transmit torque!
Check temperature, force and material
If you can't find the original ones of the same quality, you can also solve this problem by choosing ones with a larger outer diameter of the moving components.
