FQW Series Pneumatic Submersible Pump

This model is versatile and well-suited for application in any underground mine with the presence of gas or coal dust, specifically in dangerous and explosive working conditions. Its primary function is to pump water containing powdered coal and sediment particles. Not only is it safe and reliable, but it also plays a crucial role in enhancing air quality at the worksite.

1.Low noise, kept within 40 decibels, can be dived, and there is no noise in diving; 

2.Small air consumption and high efficiency. 

3.Small size, light weight, compact structure and portability. 

4.The whole pump is made of cast steel, with a longer service life and few wearing parts, which is easy to maintain.

The mining pneumatic submersible pump comprises three main components: the pump body, air motor, and flow parts.

1.Pump Body: The pump body is divided into upper and lower cavities, and a seal ring separates  

the gas and water in the middle. A spring seal is employed, utilizing steam and water pressure to drive high-pressure steam and water into the upper and lower seals, causing them to expand. This mechanism enhances the sealing effect.

2.Air Motor: The air motor is composed of a rotor, turbine, upper and lower cylinders, bearings,  

etc. 2. Compressed air serves as the driving force, pushing the turbine to rotate and drive the rotor at high speed.

3.Flow Parts: The flow parts include the water turbine, pump cover, suction inlet, and pump       

seat. The water turbine is mounted on the rotor shaft in the lower cavity of the shell. Compressed air enters through the inlet, and the rotor's rotation drives the water turbine. This action pumps water into the vortex street of the shell under centrifugal force, and the water is discharged through a pipe.
