What are the applications of deep well pumps？

A deep well pump is a water lifting device that is directly connected to a motor and a water pump to submerge into the water. It is suitable for extracting groundwater from deep wells, and can also be used for water lifting projects such as rivers, reservoirs, and canals: mainly used for irrigation of farmland and water for humans and animals in plateau and mountainous areas. It can be used for water supply and drainage in cities, factories, railways, mines and construction sites. Since the deep well pump is operated by the motor and the water pump body directly submerged in the water, its safety and reliability will directly affect the use and work efficiency of the deep well pump. Therefore, the deep well pump with high safety and reliability has become the first choice.

In underground water source heat pump air conditioning systems, often the water supply of one deep well pump can meet the water demand of two or more heat pump units. However, in actual operation, it was found that the heat pump unit was operating at partial load most of the time, while the deep well pump had been operating at full load, which resulted in a substantial increase in electricity and water costs.

Frequency conversion speed regulation technology is widely used in water pumps and fans in air conditioning systems due to its significant energy-saving effects and reliable control methods, and its technology is relatively mature, but it is rarely seen in the application of deep well pump water supply in underground water source heat pump air conditioning systems. , But it is quite necessary. A pilot survey of groundwater source heat pump applications in Shenyang found that in groundwater source heat pump air conditioning systems, when the heat pump capacity is not large, the water supply of a deep well pump can meet the water requirements of two or more heat pump units. In actual operation, it is found that the heat pump unit is running at part load most of the time, while 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 potential for energy saving.
