Deep well pump is a kind of pumping equipment specially designed for extracting groundwater from deep wells. It is usually composed of key components such as motor, pump body, transmission shaft, water pipe and sealing device. The working principle of deep well pump is based on the action of centrifugal force. When the motor is started, the transmission shaft drives the impeller in the pump body to rotate at high speed, and the liquid is thrown out and transported to the ground under the action of centrifugal force.
The main components of deep well pump are motor, pump body, transmission shaft, water pipe and sealing device. The motor provides power, the pump body is responsible for pumping water, the transmission shaft connects the motor and the pump, the water pipe transports water from the bottom of the well to the ground, and the sealing device prevents water from entering the motor part1. The working principle of deep well pump is to generate centrifugal force through the high-speed rotation of the impeller, suck the liquid into the pump body and discharge it after pressurization.
Types and models
There are many types of deep well pumps, including long-axis deep well pumps and deep well submersible pumps. The long-axis deep well pump is usually a vertical single-suction multi-stage centrifugal pump, which is suitable for extracting groundwater from deep wells; while the deep well submersible pump has the advantages of simple structure, high efficiency, low noise, safe and reliable operation, and is suitable for various occasions such as farmland irrigation and urban water supply. 34.
Application fields
Deep well pumps are widely used in agricultural irrigation, industrial water supply, urban water supply, mine drainage and other fields. Its large flow and high head make it particularly suitable for extracting groundwater from deep wells, and it is not limited by the liquid level concentration. 13. In addition, deep well submersible pumps are also suitable for extracting water from rivers, reservoirs and other water sources, and are widely used in farmland irrigation, urban water supply, industrial water use, etc. 4.
