agricultural irrigation pump introduction and classification

agricultural irrigation pump is a submersible motor as the driving force, the motor and the pump assembled into one into the underwater operation of the water lifting machinery, there are small submersible pumps, sewage submersible pumps, submersible pumps and submersible screw pump And so on several types. agricultural irrigation pump is small and lightweight, cheap, easy to operate, in rural production and life plays an important role. With the development of rural economy, submersible pump products are widely used in farmland irrigation, sewage removal and extraction of well water reference and so on.

agricultural irrigation pump type

1, axial flow pump, mixed flow pump, diagonal pump and screw pump
There are many types of agricultural irrigation pump, in some large irrigation and drainage stations are mostly use axial flow pump, mixed flow pump, diagonal pump and screw pump. Their common characteristics are large flow, low head, simple structure, easy to install and use. They are mainly used in large area watershed irrigated farmland and flood control floods. Axial and diagonal pump The impeller on the impeller can be divided into two kinds of fixed and adjustable, so change the installation angle of the blade can change the working conditions of the pump. Axial pump due to changes in the angle can cause changes in the head, but the magnitude is not, the flow is a big change. Oblique flow pump can change the angle can cause the head and the flow has the big change.

2, water pump, water hammer pump and self-priming pump (medium water and mud two)

A water pump and a water hammer pump are a pump that does not require mechanical power. They are using a certain gap and flow of small streams of water as the driving force. Mostly in the mountains of small pieces of land irrigation, irrigation or drip irrigation. This pump as long as the dam after the repair canal, a certain drop of water into the pump which can be high to the water. Self-priming pump works is: before the pump starts in the pump casing filled with water (or pump itself with water). After the start of the high-speed rotation of the impeller so that the impeller channel flow of water to the volute, then the entrance to form a vacuum, so that the water back door open, the suction pipe into the pump air, and impeller channel to the outer edge. Self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, smooth operation, easy maintenance, high efficiency, long life and strong self-priming ability. Pipeline do not need to install the end of the valve, just before the work to ensure that the pump can be stored within the quantitative solution can be. Different liquids can use different materials from the suction pump.

agricultural irrigation pump category

In the province of rural areas, deep well pumping, pond irrigation and drainage, land irrigation is often used in QJ deep well submersible pumps, QS large diameter flow cast iron pumps, etc., in environmental protection, sewage treatment, excavation of small rivers, dig pond fish , The use of sewage pump, mud pump, sand pump, no plug pump and other pumps. These pumps can transport sewage, both the discharge of sludge water, but also the river water to mention the established emissions, easy to use and convenient, so more popular with rural users
