Multi-stage pump performance characteristics:
1: Multi-stage pump is mainly used for mine drainage, city and factory water supply.
2: Compared with reciprocating pumps such as piston pumps and diaphragm pumps, it can also pump larger flow rates.
3: The multi-stage centrifugal pump has high efficiency, can meet the needs of high lift and high flow conditions, and has been widely used in petrochemical, chemical, electric power, construction, fire protection and other industries.
4: Due to its particularity, compared with single-stage centrifugal pumps, multi-stage centrifugal pumps have different and higher technical requirements in terms of design, use, maintenance and repair.
Working principle of multistage pump:
1: Compared with single-stage pumps, multi-stage centrifugal pumps have the difference that multi-stage pumps have more than two impellers, which can absorb water and pressurize water in stages in multiple stages, thus lifting water to a high position The number of pump impeller stages can be increased or decreased according to need.
2: There are two types of multistage centrifugal pumps, vertical and horizontal
3: The pump shaft of the multistage centrifugal pump is equipped with two impellers connected in series
4: Compared with the general single-stage centrifugal pump, the multi-stage pump can also achieve a higher head.
