What is the working principle of deep well pump？

Deep well pump is a water-lifting device that works by directly connecting the motor and the pump to submerge into the water. It can be used for water supply and drainage in cities, factories, railways, mines, and construction sites. Since the deep well pump is directly submerged into the water by the motor and the pump body, its safety and reliability will directly affect the use and efficiency of the deep well pump. Therefore, the deep well pump with high safety and reliability has also become the first choice .

In a groundwater source heat pump air-conditioning system, a deep well pump can often supply enough water for two or more heat pump units. However, in actual operation, it was found that the heat pump unit was running at part load most of the time, and the deep well pump was always running at full load, resulting in a large increase in electricity and water charges.

Frequency conversion speed regulation technology is widely used in air-conditioning systems for water pumps and fans due to its significant energy-saving effects and reliable control methods, and its technology is relatively mature., But it is quite necessary. A pilot survey of groundwater source heat pump applications in Shenyang found that in a groundwater source heat pump air conditioning system, when the heat pump capacity is not large, the water supply of a deep well pump can meet the water demand of two or more heat pump units. In actual operation, it was found that the heat pump unit runs part-load most of the time, and the deep well pump has been running at full load, resulting in a large increase in electricity and water charges. Therefore, the application of deep well pump variable frequency speed regulation water supply technology in groundwater source heat pump system has great energy saving potential.
