Pumps are available in a wide variety of applications and in a wide range of applications in the national economy. In agriculture, water pumps are mainly used for irrigation and drainage in farmland. They can be irrigated by drought, can be drained when they encounter floods, improve their ability to overcome floods and droughts, ensure high yield and stable yield of crops, and promote agricultural and sideline production.

Common types of agricultural water pumps include centrifugal pumps, axial flow pumps, mixed flow pumps, well pumps, submersible pumps, and water wheel pumps.

In agricultural production, different performances of irrigation and drainage machinery should be selected according to the requirements of production conditions in different regions.

In the northern region, due to the lack of surface water, groundwater must be developed to water the farmland. Therefore, deep well pumps, shallow well pumps, submersible pumps, etc. are widely used. Therefore, it is necessary to select the irrigation and drainage machinery according to local conditions.

In plain areas, such as the Pearl River Delta region of our province, the river network has sufficient water resources, vast fields, dry autumn and winter, and heavy rain in summer. It often encounters heavy rain, heavy rain, and waterlogging on farmland, requiring rapid drainage. Due to the low terrain and low lift in these areas, the amount of water delivered by farmland irrigation or drainage is quite large, and axial flow pumps with “low lift and large flow” performance characteristics should be adopted.

In the mountainous area of ​​northern Guangdong, due to the small size of the field, the lifting water head is higher, and the flow rate is not large, it is better to use a centrifugal pump with performance characteristics of “high lift and small flow”. In view of the steep flow of mountainous mountains and abundant water resources, the water pump can be promoted to solve the irrigation of highlands and hills.

In the hilly area near Guangzhou, the hills are not high, the plot is not very large, and the performance of the pump is suitable. The flow rate is smaller than that of the axial flow pump, but it is larger than the centrifugal pump flow; the lift is smaller than the centrifugal pump, and A mixed flow pump with a higher lift than the axial flow pump.
