In order to ensure that the centrifugal pump can be used normally for a long time, it needs to be overhauled on a regular basis, so as to detect and deal with the failure of the equipment in time. However, it needs to be disassembled and washed in the process of its maintenance operation, and a problem in the disassembly and washing operation will cause loss of some parts in the equipment, so you need to be extra careful when performing the disassembly and washing operation, such as:
1. Disassembly, assembly and cleaning of mechanical centrifugal pumps should be carried out in a clean room. When disassembling and washing, you should pay attention to the original assembly position, square and combination tightness of each component, and make a record at the same time to avoid incorrect assembly.
2. When taking out the rotary vane and rotor of the pump, you must pay attention to the rotary vane by hand. The reason is that the rotary vane has a large inertia due to the spring force. If it is accidentally released, it will easily fly out and damage the edge or surface of the rotary vane and cannot continue. use.
3. The dismantled parts should be separated and handled properly to avoid being injured or lost.
4. When assembling the centrifugal pump, apply a small amount of pump oil to the surface of the rotating part for lubrication. Pay attention to clean, and it is strictly forbidden for iron filings, mud sand and dust to fall into the pump. The installed pump should rotate easily, without unevenness and blockage.
5. After the centrifugal pump is assembled, add pump oil from the oil filling hole to the oil mark line.
6. Before starting the equipment, inject a small amount of pump oil into the suction port to make the pump fully lubricated. (The reassembled pump should be tested for several hours to see if it meets the requirements for use).
