Abstract

The invention discloses a pneumatic pump for dredging a water sump and a working method of the pneumatic pump, and belongs to the technical field of dredging equipment. The pneumatic pump comprises amain pump body, a pneumatic motor and a coupler, wherein the pneumatic motor is fixedly mounted at the top of the main pump body through a flange, an output shaft of the pneumatic motor is connected with a main shaft of the main pump body through the coupler, and impellers used for stirring, centrifuging and outputting fluid are mounted at the tail end of the main shaft. According to the technicalscheme, the pneumatic pump can be used under the relatively complicated working conditions of the water sump, and cannot be limited by using above or below water.

Description

technical field

[0001] The invention relates to the technical field of desilting equipment, in particular to a pneumatic pump for desilting a water tank and a working method thereof. Background technique

[0002] At present, the dredging pumps commonly used in coal mine underground water tanks are mainly vertical or horizontal slurry pumps for pumping sludge. They are driven by ordinary explosion-proof motors, do not have waterproof function, and cannot be used in diving. The pumps used to extract the clean water from the tank are mainly submersible pumps or centrifugal pumps. Submersible pumps can only be used underwater and cannot be used on the water surface, while centrifugal pumps are not waterproof and cannot be used in diving. Therefore, at present, the dredging pump used in the dredging of the water tank has many limit value conditions, which is prone to failure, burning of the motor and other problems, and cannot serve the dredging of the coal mine tank well.
