QDX type (aluminum shell) single-phase submersible electric pumps are widely used in rural underground pumping, farmland irrigation, garden irrigation and domestic water. It can also be used to pump industrial stagnant water and aquaculture water.

 

QDX, QX series submersible pumps are single-phase or three-phase motor-under-type pump structures. Double mechanical seals are used between the pump and the motor. The motor is equipped with a protection device that can cut off the power supply in abnormal conditions such as excessive temperature and overload in the machine. , Protect the motor.

 

The water pump is located at the lower part of the electric pump and has a centrifugal impeller and volute structure; a double-end mechanical seal is used between the water pump and the motor, and each fixed stop adopts an "O"-shaped oil-resistant rubber sealing ring as a static seal.

 

QDX type (aluminum shell) single-phase submersible electric pump service conditions:

 

1. The working medium is non-corrosive clean water, the volume of sand content in the medium is not more than 0.10%, and the particle size is not more than 0.20mm.

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

3. The electric pump should be used within the range of use near the rated head.

4. The electric pump should be completely immersed in water. The diving depth should not exceed 3m, and the depth should not exceed 5m. The electric pump should be more than 0.5m from the bottom of the water, but it should not fall into the mud.

5. The power frequency is 50HZ, the single-phase voltage is 220V, and the voltage fluctuation range is 0.9-1.1 times the rated value.
