BQF series of wind-driven submersible pump 
 BQF pneumatic submersible pumps have BQF-Ⅰ, BQF-Ⅱ, BQF-Ⅳ three models. Such wind-driven submersible pump in accordance with domestic mining the actual needs of the construction site, to learn foreign advanced products of the strengths of the same type, using a range of advanced technology, it is small, light weight, novel structure, convenient operation, easy installation, maintenance and mobile and so on. For mine development, construction of wells roadway or Shaft place different environmental conditions such as drainage work. The pump used in the power part of the vane motor, with automatic centrifugal governor structure, to ensure operation at the rated speed range. Is a high efficiency, high head mine wells, building water wells in the ideal tool.

 Structural features: BQF series pneumatic submersible pumps by our company experts, Engineering analysis, weaknesses, for research, while maintaining the original product based on the shape of the structure size, were a major breakthrough improvements. 
 A redesigned air motor parameters, greatly improving the air motor shaft power. 
 Second, for noise reduction within the muffler shell structure is designed to adjust the intake position, so that the exhaust air collision within the shell, cross-dry 
 After expansion into the external interference with independent intellectual property muffler, a radical improvement in the underground construction of the real working conditions. 
 Third, the leaf air motor strength, thickness re-calculated according to the latest check at home and abroad to improve the strength of the blade bending distortion; 
 And leaves was special treatment, so that leaves wear and durability, the abrasion leaves other manufacturers of wind pumps several times, reducing the dimension 
 Repair replacement blades, the number of cylinders, greatly improving the user units of the economic benefits. 
 Fourth, in the vortex interior configuration of new composite impeller (the leaf is applying for utility model patents), to further improve the head. 
 BQF series of wind-driven submersible pump will be full of new vitality, a new generation series of drainage equipment.
