Preparatory Work Before Mechanical Seal Start

1. Comprehensively check the mechanical seal, whether the attachments and pipeline installation are complete, and whether they meet the technical requirements.

2. Before starting the mechanical seal, perform a static pressure test to check whether the mechanical seal is leaking. If there are too many leaks, find out the cause and try to eliminate it. If it is still invalid, it should be disassembled, checked and reinstalled. Generally, the static pressure test pressure is 2~3 kg/cm².

3. Rotate the pump to the crank to check whether it is brisk and even. If the crank is difficult or does not move, check whether the assembly size is wrong and whether the installation is reasonable.
