1.Working principle

The working principle of circulating pump for high flow sprinkler irrigation system is similar to that of general centrifugal pump or mixed flow pump. When the pump starts, the motor drives the impeller to rotate, thus generating negative pressure in the pump body and sucking the water from the water source into the pump body. As the impeller rotates, the water is thrown out and generates a certain pressure, and then transported to the sprinkler irrigation system through the pipeline. In the sprinkler irrigation system, the water is evenly sprayed onto the farmland or other irrigated areas.

2.Main Features

• Large flow rate: the main feature of the circulating pump of large flow rate sprinkler irrigation system is the large flow rate, which can meet the irrigation demand of large farmland. The flow rate is usually more than hundreds of cubic meters per hour, depending on the model and specifications of the pump.

• High performance: Recirculation pumps are usually designed for high performance to increase irrigation efficiency and reduce energy consumption.

• Corrosion resistance: Since sprinkler systems typically use fresh water or irrigation water with small amounts of impurities, recirculation pumps need to have good corrosion resistance to ensure long-term stable operation.

• Easy to maintain: high-flow sprinkler irrigation system circulating pump structure design is usually relatively simple, easy to maintain and overhaul.

3. Selection considerations

• Flow demand: according to the irrigation area and the design requirements of the sprinkler system to determine the required flow range.

• Lift requirements: according to the height difference between the water source and the irrigation area, to determine the required range of head.

• Pump type: according to the specific application scenarios and needs, select the appropriate type of pump, such as centrifugal pumps, mixed flow pumps. For high flow sprinkler irrigation system, mixed flow pump may be a good choice, because it combines the advantages of centrifugal pump and axial flow pump, with large flow rate and moderate head.

• Material selection: According to the nature of the irrigation water and the working environment, choose the appropriate pump body and impeller material. For irrigation water containing corrosive substances, the material with better corrosion resistance should be selected.

• Brand and quality: choose well-known brands and high-quality products to ensure reliable pump performance and quality.

4.Application Scenario

High-flow sprinkler irrigation system circulating pumps are widely used in farmland irrigation, orchard irrigation, landscaping and other fields. Especially in occasions where large area irrigation is required, such as large farms, orchards, etc., high flow sprinkler irrigation system circulating pump can provide stable water flow to meet the irrigation demand.
