Submersible pumps are important equipment for deep well water extraction. When in use, the whole unit dives into the water to work, extracting groundwater to the surface, which is used for domestic water, mine rescue, industrial cooling, farmland irrigation, seawater lifting, shipload regulation, and can also be used for fountain landscapes. The development and use of water pumps are combined with scientific and technological progress, and there are many types of water pumps. Submersible pumps can be divided into well submersible pumps, working surface submersible pumps, submersible sewage pumps, sand discharge submersible pumps, mining vertical pumps, etc.

Submersible pump classification:

Well submersible pump

The clear water submersible pump is a multi-stage pump, which is mainly used to lift water from machine wells, earth wells or reservoirs in the clay layer, and is suitable for irrigation in factories, mines, or farmland. In 1928, the American company Byron Jakson 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".

Working surface submersible pump

The working surface submersible pump is a small submersible pump (single-stage pump), which is widely used in many places due to its easy installation and convenient use. 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 also began mass production. China began to produce "working surface submersible pumps" in 1958, and developed into "QY submersible pumps (oil-filled)" in the 1960s, "QS submersible pumps (water-filled)" in the 1970s, and "QY submersible pumps (water-filled)" in the 1980s. QX and DQX submersible pumps (dry)”. 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 fields because of their outstanding advantages such as simplifying pump structure and saving investment in pump station construction.

Submersible sewage pump

The submersible sewage pump is mainly used to transport industrial wastewater and urban domestic sewage, and 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. In 1956, the Swedish Flygt (Sterbery-Flygt) developed the first "submersible sewage pump", which reduced the cost of sewage stations by about half. China introduced and produced "submersible sewage pumps" from Germany in the late 1980s, mainly including WQ, QW, AS series products. (According to statistics, about 1995, the annual domestic output of "submersible sewage pumps" was about 50,000 units.)

Sand removal submersible pump

China's first "sand removal submersible pump" was developed by Professor Wang Qingwu in 1989. The KGQ12-50 type sand removal submersible pump was developed in 1989. After years of development, the product now produced is the fourth generation of sand removal submersible pump - mine use the vertical pump. The submersible sand pump is specially designed for the drainage environment rich in sediment in the water and 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 water, such as mines, engineering excavation, rescue and disaster relief, environmental protection, and sand removal. Drainage in the environment rich in sediment, life is 5 to 10 times that of the submersible sewage pump and the clean water submersible pump.

Mine vertical pump

Mine vertical pump, the fourth-generation new sediment discharge submersible pump, is an integrated product of vertical pump and submersible pump. It can be used as both a submersible pump and a vertical pump. It inherits the advantages of submersible pumps and vertical pumps, and has exceeded With the concept of submersible pumps, it is a veritable "amphibious pump". According to the development of submersible pumps, mining vertical pumps belong to the evolutionary products of submersible pumps that "go out of water and land onshore".
