A water pump is a device used to transport liquids, gases, or liquid-solid mixtures. In the field of agricultural irrigation, water pumps are usually used to extract water from a water source (such as a well, river, lake, or reservoir) and transport it to farmland for irrigation. Pumping water machine mechanically pump water or other liquids from one place to another, providing a continuous supply of water to ensure that crops get enough water during the growing season.
There are many types of water pumps, including centrifugal pumps, plunger pumps, and plunger pumps, each type of pumping water machine has its specific uses and advantages. In agricultural irrigation, centrifugal pumps are common because they can transport water over longer distances and have high efficiency and adaptability.
The operating principle of a pumping water machine is basically to use mechanical energy to suck water in and transport it through a pipeline to where it is needed. This mechanical equipment plays an important role in modern agriculture, helping farmers manage water resources more effectively, increase crop yields, and achieve sustainable development of agricultural production.
1. The basic principle of water pump in agricultural irrigation
1.1 Working principles of different types of water pumps
① Centrifugal pump:
Working principle: The centrifugal pump generates centrifugal force by rotating the impeller, draws the liquid in from the inlet and discharges it through the pump body.
Features: Suitable for conveying clean water and slightly polluted liquids, with high efficiency and large flow.
② Plunger pump:
Working principle: The plunger pump generates pressure by the up and down movement of the plunger in the cylinder, pushing the liquid out of the pump body.
Features: Suitable for high pressure and small flow occasions, with stable output pressure and precise flow control.
③ Screw pump:
Working principle: The screw pump sucks the liquid from the inlet and compresses it to the outlet through the rotation of the screw.
Features: Suitable for conveying high-viscosity liquids and solid-liquid mixtures, with stable flow and conveying capacity.
