Problems solved by technology

Mine pneumatic (pneumatic) pumps have a remarkable feature. Due to the portability of the pump, a pump is often used in many occasions, the operating conditions are extremely complex, and the actual operating conditions often change, including compressed air pipelines. The pressure and flow change; and there is no flow regulating valve in the water discharge pipeline, which only means that the mining air pump is operating under the condition of large flow, but most of the actual head cannot meet the user's requirements. At present, it can only solve the work of the working face. Site Drainage Requirements

Abstract

The invention discloses a bi-energy pneumatic submersible pump for a mine. A motor seal chamber is formed between a motor and a variable speed transmission device. An output end seal chamber is formed between a water pump and the variable speed transmission device. A variable speed seal chamber is formed between a motor seal chamber and the output end seal chamber. The output shaft of the motor is the input shaft of the variable speed transmission device. The output shaft of the variable speed transmission device is the power shaft of the water pump. By the above method, the bi-energy pneumatic submersible pump for the mine is strong in adaptability. Therefore, the bi-energy pneumatic submersible pump for the mine can be designed by matching a speed reducer and a speeder between two categories of pneumatic motors and the water pump, so that requirements of high flow and high-lift dewatering pump are thoroughly resolved under poor working conditions of an environment, a flammable and explosive environment and a moist environment. The bi-energy pneumatic submersible pump for the mine has the advantages of being large in bi-energy driving torque, high in anti-impact properties and mechanical efficiency, and flexible to start. Further, according to the bi-energy pneumatic submersible pump for the mine, water draining can be achieved when the bi-energy pneumatic submersible pump starts under low pressure, water pump performance curve is flat, and operation under requirements of high flow and high lift can be achieved.

Description

technical field [0001] The invention relates to the field of pneumatic water pumps, in particular to a dual-power mine-used pneumatic submersible pump. Background technique [0002] The standard efficiency of vane pneumatic submersible pumps used in coal mines is only 29%~48%. Mine pneumatic (pneumatic) pumps have a remarkable feature. Due to the portability of the pump, a pump is often used in many occasions, the operating conditions are extremely complex, and the actual operating conditions often change, including compressed air pipelines. The pressure and flow change; and there is no flow regulating valve in the water discharge pipeline, which only means that the mining air pump is operating under the condition of large flow, but most of the actual head cannot meet the user's requirements. At present, it can only solve the work of the working face. Site drainage needs. Contents of the invention [0003] The technical problem mainly solved by the present invention is t...
