Abstract

The invention discloses a pneumatic motor for a submerged pump. The pneumatic motor comprises an air cylinder and a rotor shaft in the air cylinder, wherein an upper end cover and a lower end cover are respectively arranged at the two ends of the air cylinder; the two ends of the rotor shaft are respectively assembled in a bearing in the upper end cover and a bearing in the lower end cover; the side wall of the air cylinder is provided with a forward rotary air inlet, a backward rotary air inlet and exhausting openings; and the exhausting openings is divided into a first exhausting opening set, a second exhausting opening set and a third exhausting opening set. In the manner, the pneumatic motor for the submerged pump disclosed by the invention has a good exhausting effect, and the use performance of the pneumatic motor is improved.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to an air motor for a submersible pump. Background technique [0002] Air motors are widely used in mining industry, paper industry, petrochemical machinery, ship machinery and other fields. An air motor is a device that converts the pressure energy of compressed air into rotational mechanical energy. Its function is equivalent to that of an electric motor or a hydraulic motor, that is, the output torque is used to rotate the drive mechanism. [0003] Vane-type air motors are the most common type of air motors. Existing vane-type air motors do not have a good exhaust effect, which affects the performance of the air motors. Contents of the invention [0004] The technical problem mainly solved by the present invention is to provide an air motor for a submersible pump, which has better exhaust effect and improves the performance of the air motor. [0005] In order to solve the abo...
