QD type multi-stage submersible electric pump features submersible electric pump applications

Description :

　　The QD type multi-stage submersible electric pump consists of three parts: water pump, seal, and electric motor. The water pump is located at the upper part of the electric pump and has a multi-stage centrifugal impeller with radial guide vane structure. The electric motor is located at the lower part of the electric pump and has a single-phase or three-phase asynchronous motor structure; Double end mechanical seals are used between the water pump and the electric motor, and "O" - shaped oil resistant rubber seals are used for static sealing at each fixed stop seal. The QD type multi-stage submersible electric pump adopts a multi-stage impeller structure, with high head and wide applicability. It is an essential water supply and drainage tool for agricultural irrigation, garden sprinkler irrigation, underground water lifting, water tower delivery, urban construction, industrial and mining enterprises, and other occasions.

　　Working conditions of QD type multi-stage submersible electric pump

　　QD type multi-stage submersible electric pump can work continuously and normally under the following usage conditions:

　　1. The working medium is non corrosive clean water, with a sand content of no more than 0.1% by volume and a particle size of no more than 0.2mm.

　　2. The temperature of the medium should not exceed 40 ℃, and the pH value of the medium should be between 6.5-8.5.

　　3. Electric pumps should be used within the range of their rated head. And fully immersed in water for use, with a diving depth of no more than 5m

　　4. The power frequency is 50Hz, the voltage is 220V for single-phase and 380V for three-phase, and the voltage fluctuation range is 0.9-1.1 times the rated value.
