In order to ensure stable operation, long life and low leakage performance of the mechanical seal, it is very important to install it correctly on the machine. Things to be aware of when installing:
1. Confirmation of parts
When installing the mechanical seal on the machine, it should be well compared with the general assembly drawing before installation to confirm whether the parts are ready. In this case, pay attention to the abnormal phenomenon such as sealing and rubbing the sealing surface and sealing ring. Also, pay attention to the shaft or sleeve surface, flange and other parts that are in contact with the packing, sealing ring (O-ring), etc., if there is any abnormality, it must be replaced or repaired before use.
When actually installing, do not bring more than necessary parts to the site. If the parts are left after installation, there will be missing parts during installation. If the parts are insufficient, it means unnecessary parts are assembled. The parts are on, which also plays a role in self-test during installation.
(Some people think that a good assembler does not need drawings and other marks. This is wrong. Then he is just a skilled worker and not a good repairman.)
2, the installation location
The installation method varies with the type of mechanical seal and the type of machine. I won't go into details here.
