Common types of agricultural pumps are centrifugal pumps, axial pumps, mixed flow pumps, well pumps, submersible pumps, water pumps and so on.
In agricultural production, should be based on different regions of the production conditions, the choice of different performance of irrigation and drainage machinery.
In the plain area, the river network of water is abundant, broad fields, autumn and winter drought, summer rain, often heavy rain, storms, farmland waterlogging, requiring rapid drainage. These areas due to low-lying, lift head is not high, but the farmland irrigation or drainage of the water volume is quite large, should be used "low head, high flow" performance characteristics of the axial flow pump.
In the mountainous area, due to small plots, lift head is high, and the flow is not, should use the performance characteristics of "high-lift, small flow" of the centrifugal pump. In view of some mountainous mountain steep stream, has a wealth of water resources, can promote the use of water turbine, in order to solve the highlands, hillock irrigation.
In the hilly areas, the hills are not high, plots are not large, suitable for use pump performance, the flow rate than the axial pump is small, but also larger than the centrifugal pump flow; head smaller than the centrifugal pump, Flow pump head high mixed-flow pump.
In the northern region, due to the small surface water, groundwater to be developed to irrigate farmland, it is widely used deep well pump, shallow well pump, submersible pump.
Therefore, the choice of irrigation machinery must be adapted to local conditions.
