Introduction:

Mine pneumatic submersible pump is developed by our company can be a new product, this product USES coaxial rotor and the pump body connection of mechanical products, the vertical structure, the pump.

FQW series pump is suitable for the dangerous sites containing gas and coal-dust explosion drainage operation, can be widely used in the coal mine for any operation to deliver a pulverized coal, the sediment particles of groundwater, the use of safe, reliable, and effectively improve the air quality.

 

 

 

 

 

Product structure & working principle

Mine pneumatic submersible pump:Pump body, gas motor and Over current.

 

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.

 

 

Working environment:

 

1. Have gas and coal dust in the air
