How to install a horizontal multistage centrifugal pump
Installation precautions for horizontal multistage centrifugal pumps:
1. The weight of the pipeline should not be borne on the pump during installation, otherwise the pump will be easily damaged;
2. The anchor bolts must be tightened during installation, and the pump should be checked every certain period of time to prevent it from loosening, so as to avoid severe vibration when the pump is started and affect the performance of the pump;
3. Before installing the pump, carefully check whether there are hard objects (such as rocks, iron sand, etc.) in the pump flow path that affect the operation of the pump to avoid damage to the flow components during the operation of the pump;
4. For easy maintenance and safe use, install a regulating valve on the inlet and outlet pipelines of the pump and a pressure gauge near the inlet and outlet of the pump. For high-lift pumps, to prevent water hammer, it should be installed before the outlet gate valve. A non-return valve to deal with accidents caused by power loss such as sudden power failure, so as to ensure that the pump runs under the best conditions and prolong the service life of the pump;
5. When the pump is used for suction, it should be equipped with a bottom valve, and the inlet pipeline should not have too many bends, and there should be no water or air leakage, so as not to affect the suction performance of the pump;
6. In order to prevent impurities from entering the pump and blocking the flow path to affect performance, a filter should be installed in front of the pump inlet;
7. Rotate the rotor parts of the water pump before installing the pipeline. There should be no friction or jamming. Otherwise, the pump should be disassembled to check the cause. The above content is organized based on the problems encountered by the students in actual work for reference. If you have any problems, please communicate and correct them in time.
