Horizontal multi-stage centrifugal pump is a type of centrifugal pump, there are vertical and horizontal points. Generally used in floor water supply and circulating water, this kind of pump has no suction head, so it can only be installed on the pipe.
The common problem of horizontal multi-stage centrifugal pump is that when the horizontal multi-stage centrifugal pump is selected, the outlet pressure of horizontal multi-stage centrifugal pump can not meet the requirements of use
Analysis of low outlet pressure of horizontal multistage centrifugal pump
1. The reverse phenomenon of horizontal multistage centrifugal pump appears, which is contrary to the design concept; The pump should be stopped immediately and the direction should be adjusted in time.
2. The cavitation phenomenon of horizontal multistage centrifugal pump may be caused by the low suction pressure.
3. The viscosity of the medium is very large, which does not meet the requirements of the horizontal multi-stage centrifugal pump. The medium is not within the allowable range, so the amount of the pump can not meet the requirements of the user.
4. The common reason is that after the pump has been used for a period of time, the impeller of the rotor part inside the pump is excessively worn, so the pump should be overhauled or the impeller should be replaced. Regular maintenance of the pump, can effectively improve the performance of the pump, can also greatly extend the service life of the pump.
Horizontal multi-stage centrifugal pump outlet pressure can not meet the requirements of use, should consider all aspects of the factors for all aspects of inspection.
