Pneumatic motor submersible pump

Abstract

The invention belongs to the field of water pumps and provides a pneumatic motor submersible pump. The power of the water pump is supplied by a pneumatic motor (2); and an air inlet (1) and an air outlet (3) are arranged on the pneumatic motor (2). The pneumatic motor submersible pump is characterized in that a power output shaft (4) of the pneumatic motor (2) is directly connected with a power input shaft (6) of a speed increasing box (7) by a shaft coupler (5) so as to enable the rotating speed of the pneumatic motor (2) to be increased by the speed-increasing box (7) and the pneumatic motor (2) is connected with the impeller (10) of the water pump (12) by a high-speed rotating shaft (8); the water enters a duct of the impeller (10) by the water inlet (9); during the high-speed running process, the water can be eccentrically discharged out of the duct of the impeller (10), is gathered to a water outlet duct (11), and is finally discharged out of the water outlet (13). The pneumatic motor submersible pump has the obvious characteristics that the volume is small, the weight is light, the compressed air is utilized sufficiently, the pump lift of the water can be greatly improved, and the like.

Description

technical field [0001] The invention belongs to the field of water pumps, and specifically designs an air motor submersible pump using compressed air as a power source. Background technique [0002] Traditional submersible pumps use electricity as the power source, but they cannot be used in places without power supply. The windmill invented as early as in the Netherlands can lift water, but it needs to be close to the water source. Invented ball float valve pumps in recent years have a very low utilization rate of compressed air. Contents of the invention [0003] In order to overcome the above shortcomings, an air motor submersible pump is invented, which makes full use of compressed air to push the motor to do work. [0004] The technical solution adopted by the present invention to solve the technical problem is: the power of the water pump is supplied by the air motor (2), and the air motor (2) is provided with an air inlet (1) and an air outlet (3), which is charact...

AI Technical Summary

Problems solved by technology

[0002] Traditional submersible pumps use electricity as the power source, but they cannot be used where there is no power supply. The windmill invented in the Netherlands to lift water needs to be close to the water source. Where there is a water source, there are recesses and places where the wind is weak.

In recent years, the floating ball valve pump has been invented, and its compressed air utilization rate is very low.
