In many cases, when the equipment is disassembled and assembled, the liquid ring vacuum pump follows the steps, sometimes it can not guarantee the smooth operation of the equipment, because there are few specifications and essentials to restrict the operation. During disassembly and reassembly, the following precautions should be taken:

1. Before the liquid ring vacuum pump is dismantled, the clearance of each part of the rotor is measured and recorded.

2. Avoid hammering as much as possible. The parts removed should not be bruised and kept properly.

3. Record in detail the reasons for replacement of parts and components that need to be replaced and their usage.

4. Before reassembling the water ring vacuum pump, the parts should be cleaned and the burrs repaired.

5. The "106" silicone rubber coating is used for the static sealing surface without gaskets or sealing rings. Vacuum coke grease should be applied to clean and sealed rubber seals. Sealing rings on relief valves of vacuum pumps with relief valves and flat surfaces shall not be coated with Renke grease.

6. Adjust the clearance of each part of the rotor according to the clearance list.

7. Leakage operation should be checked after all the liquid ring vacuum pumps are installed.

8. Trial operation and necessary performance test should be carried out after reinstallation. It can not be installed and used until it is normal.
