Agriculture cannot leave water, also cannot leave pump so, different area has different choice, the agricultural use pump that can choose basically has 3 kinds of big: mixed flow pump, centrifugal pump, with diving pump.
Agricultural mixed-flow pump
Mixed flow pump flow and head between centrifugal pump and axial flow pump. Small in size, light in weight, high in efficiency and wide in efficiency, simple in structure, convenient in use and easy in maintenance. Transport medium is water or similar to water, suitable for field irrigation and industrial water supply and drainage.
Mixed flow pump is a kind of pump between centrifugal pump and axial-flow pump. It has high water yield but low head.The most common type is HW hybrid pump, which can be powered by motor or diesel engine.
We can also develop various mixed flow pumps (such as vertical, mechanical seal, special materials, etc.) according to the requirements of users. Users can also change the speed of the pump within a certain range according to the specific requirements.
Agricultural centrifugal pump
The centrifugal pump works by centrifugal motion of water by rotating the impeller.There are many models to choose from, and the range of flow and head is also large. It is the most widely used pump in agriculture.Low lift centrifugal pumps can be selected in plain areas, moderate lift can be selected in hilly areas, and higher elevation can be used in multi-stage centrifugal pumps.Users should choose according to local conditions, water sources and lifting height.Common types are: IS type centrifugal pump, ISW horizontal centrifugal pump,B type centrifugal pump,BA type centrifugal pump, S/SH type double suction centrifugal pump, D/DG type multistage centrifugal pump.
Agricultural diving pump
The submersible pump is suitable for pumping water from deep Wells: it is mainly used for irrigation in farmland and plateau mountainous areas, and is mainly used in plain areas where surface water is scarce in north China.Common models are: the QJ submersible pump for Wells.
1. Submersible pump motor and pump integrated, submerged operation, safe and reliable.
2. No special requirements for well pipe and riser pipe (i.e. steel pipe well, ash pipe well, soil well, etc.);Under pressure permit, steel pipe, rubber pipe, plastic pipe and so on can be used as riser pipe.
3. Easy installation, use and maintenance, small floor space and no need of pump room.
4. Simple structure and save raw materials.
5. Whether the operating conditions of submersible electric pumps are appropriate and properly managed is directly related to the service life.
After determining the type of agricultural pump, consideration should be given to its economic performance, especially attention should be paid to the selection of pump head and flow and supporting power.It must be noted that the head (total head) indicated on the pump signage is different from the outlet (actual head) when used, which is due to a certain amount of resistance loss when water flows through the pipe and near the pipe.Therefore, the actual head is generally 10% to 20% lower than the total head, and the water yield is correspondingly reduced.Therefore, in actual use, only 80% ~ 90% of the head and flow can be estimated according to the signage. The power of the supporting power of the pump can be selected according to the power indicated on the signage. In order to make the pump start up quickly and operate safely, the power of the power machine can be slightly higher than the power required by the pump, which is generally about 10% higher.If the power is available, the pump can be purchased according to the power of the power machine.Our company specializes in the production of diesel for irrigation, welcome to purchase.
