As a general machine for conveying water, the working principle of the water pump is that the motor drives the impeller to rotate at a high speed through the pump shaft, performs work on the liquid, converts the mechanical energy into liquid energy, and transports the liquid to the destination.

In 1689, the French physicist Paben created a centrifugal pump test model. With the advent of the electric motor, the centrifugal pump has been widely developed; by 1928, the first submersible electric pump came out. The submersible pump is an electromechanical integrated device with a compact structure. When working, the submersible pump can be started only by putting it into the water. The installation is simple and the movement is convenient. Because of its simple structure, small size and convenient use, it has developed rapidly. The development and use of water pumps are combined with scientific and technological progress.

After nearly a hundred years of development, submersible pumps can be roughly divided into clean water submersible pumps, submersible sewage pumps, and sand drainage submersible pumps.

Clearwater submersible pump - well submersible pump

In 1928, the American company Byron Jackson first developed a submersible electric pump. In the 1930s, Germany, the United Kingdom, the United States, Japan and other countries began to produce "deep well submersible pumps".

In the 1960s, my country began to produce "NQ-type agricultural deep-well submersible pump", and then gradually improved it to the present "JQ-type deep-well submersible pump".

Well, submersible pumps are multi-stage pumps, mainly used to lift water from machine wells, earth wells or reservoirs in clay layers, and are suitable for irrigation in factories, mines or farmland.

Clear water submersible pump - working submersible pump

In 1948, the Swedish Flygt (Sterbery-Flygt) first developed the "working surface submersible pump". In the 1960s, the United States, Britain, Germany, Japan, the Soviet Union and other countries started mass production one after another. It was not until 1958 that my country began to produce "working surface submersible pumps", which developed into "QY submersible pumps" in the 1960s, "QS submersible pumps" in the 1970s, and "QX and DQX submersible pumps" in the 1980s.

In the late 1980s, "working surface submersible pumps" developed rapidly, and gradually became larger and more diversified. Large and medium-sized submersible pumps have been widely used in municipal, industrial and mining, and farmland irrigation because of their outstanding advantages such as simplifying the pump structure and saving investment in pump station construction.

Submersible sewage pump

In 1956, Flygt of Sweden developed the "submersible sewage pump" for the first time, which reduced the cost of sewage stations by about half. my country introduced and produced "submersible sewage pumps" from Germany in the late 1980s, mainly including WQ, QW and AS series products.

The submersible sewage pump is mainly used to transport industrial wastewater and urban domestic sewage. Its biggest advantage is that it can discharge impurities such as pulp and long fibers. (Therefore, it is also called a "non-clogging sewage submersible pump"). Widely used in urban sewage treatment plants, rainwater pools, pumping stations, flood control and irrigation and so on.

Sand removal submersible pump

In 1989, Professor Wang Qingwu developed the first "sand removal submersible pump" - a KGQ12-50 type sand removal submersible pump. The sand removal submersible pump is specially designed for the drainage environment rich in sediment in the water, and it is a new product that fills the international gap. . It has the characteristics of high lift and wear resistance, and is suitable for drainage in environments with a large number of sediments in the water, such as mines, engineering excavation, rescue and disaster relief, environmental protection and sand removal. In an environment rich in sediment, the service life is 5 to 8 times that of the submersible sewage pump and the clean water submersible pump.

Mine vertical pump

Mine vertical pump belongs to the fourth generation of new sediment discharge submersible pumps. It is an integrated product of vertical pumps and submersible pumps. It can be used as a submersible pump or vertical pump. It inherits the advantages of submersible pump and vertical pump, which have exceeded With the concept of a submersible pump, it is a veritable "amphibious pump".
