Mine pneumatic submersible pump Technical characteristics:

Mine pneumatic submersible pump compact structure, moving, installation, maintenance is convenient. Pump body vortex street with high efficiency and energy saving hydraulic model, special impeller design. The water pump sewage discharge ability is strong, large flow, high lift, etc

Mine pneumatic submersible pump structure:

Pump body, gas motor and Over current.

Mine pneumatic submersible pump principle

1 Pump body parts: consists of two cavity, with sealing ring to separate gas and water in the middle. With spring seal, seal ring and use of gas and water pressure, the high pressure gas and water respectively into the upper and lower two sealing ring lining, make them up, enhance the sealing effect.

2 Mazda parts: by the rotor, turbines, bearings, etc.

3 The overcurrent parts: by the water wheel, volute, pump cover, pump seat , etc. Wheel is installed on the vortex shell lumen rotor shaft, compressed air from the air inlet into the rotor drive wheel, the water in the turbine under the action of centrifugal force, the pressure into the volute out the water snails were, the discharge outlet pipe.

Mine pneumatic submersible pump Working environment:

1. Have gas and coal dust in the air

2. Working pressure is 0.4-0.7MPA

3. The PH of water in 4-10

4. Density of water is not more than 1.1 * 103 kg/m3

5. Working environment temperature (5 ~ 40)°C
