Well submersible pump is composed of well submersible three-phase or single-phase (asynchronous) motor and well submersible pump, which is submersible pump used to pump groundwater or water to high or long distance. The overall structure of the well submersible electric pump is very different from that of the ordinary land asynchronous motor.
According to the use of submersible pump submersible pump can be divided into the following seven categories.
(1) well submersible pump by well submersible three-phase or single-phase (asynchronous) motor and well submersible pump, submersible pump submersible into the underground water work, used to pump groundwater or to high or long-distance water. The overall structure of the well submersible electric pump is very different from that of the ordinary land asynchronous motor. Since the outer diameter size of a submersible well pump is strictly limited by the diameter of the well in which it is installed, both the motor and the pump are slim. The increase of the power of the motor with the same frame number used in the same well diameter or the increase of the head of the submersible pump under a certain flow rate depends only on the increase of the height of the submersible motor and the series of the submersible pump. When the power of the well submersible motor is very large and the head of the submersible pump is very high, the well submersible pump is thin and long. According to GB/T 2816 "Submersible Pumps for Wells" and GB/T 2818 "Submersible Asynchronous Motors for Wells", the power of submersible pumps for wells is o.37 ~ 220kW, the flow rate is 2~500 ni3/h, the lift is 9~598m, and the synchronous speed is 1500r/min or 3000r/min. The current production of products are mainly single-phase or three-phase, water-filled, oil-filled and shielded pump-type structure of well submersible pumps, there are also a small number of single-phase dry pump-type structure of well submersible pumps.
(2) water type submersible pump is suitable for shallow water irrigation and drainage, submersible pump for conveying water. Its power is 0. 12~15 kW or more, the flow rate is 1.5~250 m3/h, and the head is 3~130m. At present, there are mainly QY type oil-filled three-phase upper pump submersible pump, Q type dry three-phase upper pump submersible pump, OS type water-filled three-phase upper pump submersible pump, ox type dry three-phase lower pump submersible pump, QDX type dry single-phase lower pump submersible pump and QYDX type oil-filled lower pump submersible pump.
(3) sewage sewage submersible pump is suitable for conveying sewage containing dirt, solid particles, such as single-phase or three-phase submersible pump. Its power is 0. 25 ~ 1400kW, flow rate is 3~43350 m3/h. At present, the production of ow type and WQ type sewage submersible pump, etc., with single-phase or three-phase pump type dry structure submersible pump, can also be used oil-filled or water-filled structure of submersible pump.
(4) mine explosion-proof submersible pump is suitable for conveying sewage containing dirt, coal powder, sediment and other solid particles with submersible pump. Its structure is mainly dry or water-filled, flameproof, can be used in coal mine underground containing explosive gas environment. Its power is 0.55 ~ 250kW, flow rate is 3~1000 n13/h, and head is 5~200m or higher. The mine submersible sewage electric pump mainly adopts the lower pump structure, and there are also products with oil-filled upper pump structure.
(5) Axial flow submersible pump is suitable for irrigation and drainage, urban water supply, sewer drainage, especially suitable for flood control and waterlogging of pumping stations along rivers, lakes and rivers with large water level fluctuations. It is a traditional axial flow pump motor unit. Updated products. Its structure is mainly divided into two types: bulb type and flow type. The dry submersible motor with bulb type structure is placed above the axial submersible pump. In the tubular structure, the axial submersible pump and the water-filled submersible motor are combined into one. The power of the axial submersible pump is 4 ~ 280kW, the flow rate is 200~11000 m3h, and the lift is 1.6~10.35 m.
(6) mine, well with high pressure submersible pump is mainly suitable for mine drainage and well pumping, can also be used for urban water supply or river water, its outer diameter size by the well diameter limit, generally more slender, its structure is mainly water-filled pump type, vertical installation and use. Power 280-2400kW or greater, voltage is generally 6000V.
(7) large submersible pump is mainly suitable for rivers, lakes or urban water supply, pumping station water supply, flood control and drainage, the structure is mainly water-filled pump type, the outer diameter size is not limited, vertical installation and use. It can also be made into a horizontal structure according to the requirements of use. Voltage 6000V or 380V, power over several hundred kilowatts

Submersible pump installation and use of technical matters needing attention
Water Because the submersible pump unit is charged to dive into the water, the sealing and insulation performance of the motor must be reliable, and the installation and use technology must be strict. A little improper will cause problems, light will aggravate the wear of parts, heavy will burn the motor can not work. Therefore, the installation and use of submersible pump units must comply with the following technical points.

Submersible pump: pressurized water pump for domestic water supply
The self-filling and water absorption of the domestic water supply pump does not require the pump to be located below the lowest water level of the storage tank. The self-filling suction pump cannot be started at the lowest water level of the storage tank. Therefore, the storage tank should set a pump-starting water level according to the self-filling requirements of the pump. When the water level is above the pump-starting water level, the pump is allowed to start. When the water level is below the pump-starting water level, the pump is not allowed to start. However, the pump already in operation should continue to run and stop automatically when the pump reaches the minimum water level of the storage tank (as long as long as long as required, it can continue to operate even below the minimum water level). Therefore, the pump top discharge hole of the horizontal centrifugal pump and the first stage (section) pump body of the suction end of the vertical multistage centrifugal pump can be placed below the lowest design water level elevation.

How to effectively reduce the energy consumption of water pump
The internal surface of the water pump and the inner surface of the pressure water chamber (also known as the volute) are rusted and uneven. Surface corrosion bump will reduce the pump water volume by 7%-8%; Only steel brush and iron sandpaper or grinding wheel need to be polished smoothly during maintenance, which can reduce the fuel consumption or power consumption by 9%-14% during work.
