Wind-power-valley-powered pneumatic spring energy storage and circulation type water pumping system

Abstract

The invention provides a pneumatic spring energy storage and circulation type pump and a wind-power-valley-powered pneumatic spring energy storage and circulation type water pumping system, belonging to the technical field of submersible pumps. The pneumatic spring energy storage and circulation type pump comprises pneumatic spring pumps, driven by compressed air, of at least two cascaded stages, wherein the pneumatic spring pump of a first stage is connected with a compressed air source, and the compressed air discharged from the pneumatic spring pump of a former stage is used for driving the pneumatic spring pump of a next stage. The pneumatic spring energy storage and circulation type pump provided by the invention is simple in structure and can cyclically use the input compressed air, so that the pneumatic spring energy storage and circulation type pump is efficient, energy-saving, lasting and durable; meanwhile, a pump body has an automatic water absorbing function, so that the pneumatic spring energy storage and circulation type pump can be applied to places needing water pumping instead of the traditional submersible pumps and centrifugal pumps.

Description

technical field [0001] The invention relates to a pneumatic spring energy storage circulation type pump and a wind force valley electric spring energy storage circulation type pump water system, belonging to the technical field of submersible pumps. Background technique [0002] Traditional submersible pumps and centrifugal pumps use the motor to rotate to drive the impeller to generate centrifugal force to pump water up, which is inefficient and easy to break. Therefore, it is stipulated in the industry that submersible pumps need to be maintained and overhauled for about 2000 hours, which is labor-intensive. Especially in some environments that require explosion protection, or in petrochemical applications, they are subject to certain restrictions. [0003] In order to overcome the above technical problems, the inventor provided the State Intellectual Property Office with an invention patent application titled "A Airbag Type High Pressure Water Pumping Device and Its Manu...

AI Technical Summary

Problems solved by technology

[0004] First: the design of the pump body is single, and it cannot do work in a cycle, resulting in a waste of gas energy;

[0005] Second: The designed pump body has no self-priming function, and it depends on the pressure of the water itself to passively enter the water;

[0006] Third: In terms of control, flow switches and pneumatic reversing valves are used to control the process, which is complicated and inflexible;

[0007] Fourth: There is no design to use the low-valley electricity at night to store compressed air to supply the pneumatic pump to do work, and it cannot pump water when there is no wind
