Introduction to Irrigation Pumps

Introduction to Irrigation Pumps

Irrigation pumps are the "heart" of agricultural irrigation systems. Their core function is to draw water from water sources (such as rivers, lakes, reservoirs, and wells) and transport it to the farmland that needs irrigation.

I. Main Functions

Raising Water Level: Lifting water from a lower elevation to a higher one.

Increasing Water Pressure: Providing sufficient pressure for the water flow to pass through the pipeline system and ultimately flow evenly from sprinklers or drippers.

II. Common Types

Based on different operating principles and water sources, common pumps include:

Centrifugal Pumps: The most common type. Utilizes the centrifugal force generated by the high-speed rotation of the impeller to throw water out. Simple in structure, suitable for applications with large flow rates and moderate head (lifting height), such as drawing water from rivers or ponds.

Submersible Pumps: The motor and pump are integrated, operating completely submerged in water. Suitable for drawing water from deep wells and other deep water sources.

Turbine Pumps (Deep Well Pumps): Suitable for deeper wells, using multiple impellers connected in series to achieve very high heads.

Self-priming pumps: These pumps have a self-priming function, eliminating the need to fill them with water before starting. They are easy to use and commonly used for temporary or mobile irrigation.

III. Simple Summary: You can think of it as a device that forces water to flow. It solves the problem of water not being able to reach crop roots on its own, making it a key piece of equipment for achieving efficient and automated agricultural irrigation, directly impacting crop yield and quality.
