FQW50-25/Wmine pneumatic submersible pump

Introduction of FQW50-25/W mine pneumatic submersible pump

Fqw50-25 /W mine pneumatic submersible pump is suitable for drainage work in places with gas and coal dust explosion hazards, and can be widely used in any operation surface of coal mine, conveying underground water containing coal powder and sediment particles, which is safe and reliable to use and can effectively improve the air quality on site.

Technical features of FQW50-25/W mine pneumatic submersible pump

Fqw50-25 /W mine pneumatic submersible pump structure compact, easy to move, assemble and disassemble, maintenance. The pump body vortex USES the high efficiency energy saving hydraulic model, the impeller special design. The pump has the advantages of strong discharge capacity, large flow and high lift.

Fqw50-25 /W mine pneumatic submersible pump is mainly composed of pump body, air motor and overcurrent, etc.

1, pump body part: divided into the upper and lower two Chambers, the middle with a seal ring will be separated from the air, water. The sealing ring adopts spring sealing, and USES the pressure of air and water to make the high-pressure air and water enter the inner wall of the upper and lower sealing rings respectively to make the inner wall rise and enhance the sealing effect.

2. Pneumatic motor: composed of rotor, turbine, bearing, etc. The rotor is driven by compressed air and impinged by a turbine to work at high speed.

3. Overcurrent part: composed of water wheel, pump cover, suction, pump seat, etc. The water wheel is mounted on the shaft of the rotor in the lower chamber of the housing, and the compressed air is sent from the inlet. The rotor drives the water wheel. Under the action of centrifugal force, the water in the water wheel is pressed into the water vortex passage of the housing and discharged along the outlet pipe.
