Hot water submersible pumps are usually equipped with stainless steel jackets

Submersible pump manufacturers submersible pumps are assembled into units, or the submersible motor shaft extension end directly installs pump components to form a pump-integrated product, and sneak into the underground water or work in rivers, rivers, lakes, ocean water and other places. The utility model has the advantages of small volume, light weight, no need for water diversion before starting, no restriction of suction stroke, no need to set up a pump room, convenient installation and use, reliable performance, high efficiency, low price and investment saving. Widely used in water extraction from underground or rivers, lakes, agricultural irrigation and drainage, urban water supply, industrial and mining enterprises water supply and drainage.

Urban and rural building drainage, residential water, urban or industrial pollution sewage treatment, hotel and hotel sewage, textile, printing and dyeing, paper, chemical and other industries slurry transportation, farm water and sewage, manure treatment, mines, drainage, sewage It can be used in various places such as water transportation and salt water, brine transportation, etc. It can also be used for offshore oil production platform to extract seawater for flushing, cooling and fire extinguishing, for power supply, boosting, ship water supply, pipeline pressurization and seabed mineral collection. Special Occasion.

In order to determine the direction of rotation of the rotor, before the pump is finally installed, it should be lifted and joged. The direction of rotation is correct according to the following conditions. Otherwise, the position of any two of the three-phase lines on the controller should be exchanged to change the direction of rotation. Looking down from the top of the pump, the rotor rotates clockwise; from the bottom up (ie, the direction of the suction port), the vane is turned counterclockwise. If several pumps are connected to the same controller, they should be checked separately.

The power supply unit should be safe, reliable and normal. The power supply voltage and frequency should be in accordance with the regulations (voltage is 380V±5%, frequency is 50Hz±1%), and the instantaneous voltage difference should not exceed 10%. If the power supply is far away from the water pump, the cross-sectional area of the cable should be thicker, and the joint should be as small as possible. Otherwise, the voltage will drop too much, and the cable joint should be sealed and waterproofed to prevent leakage.

The submersible pump motor needs to be submerged by the whole machine. The submersible pump is mainly cooled by water. If the motor leaks out of the water and there is no water to cool the motor, the temperature will rise sharply and it will easily lead to the burning of the motor. If the liquid to be delivered is hot water below 80 degrees, hot water submersible pump must be used. The hot water submersible pump is usually cooled with stainless steel jacket and cooled by external cooling water. If it is used, it must be cooled by external tap water. If it is not connected to tap water cooling. The motor will definitely burn the motor because the medium temperature is too high to cool the motor.
