Embodiment Construction

[0032] Hereinafter, specific embodiments of the present application will be described in detail with reference to the accompanying drawings. According to these detailed descriptions, those skilled in the art can clearly understand the present application and can implement the present application. Without departing from the principle of the present application, the features in different embodiments can be combined to obtain new implementations, or some features in certain embodiments can be replaced to obtain other preferred implementations.

[0033] The ionic liquid compressor was first proposed by Linde and successfully developed in cooperation with Daimler Chrysler AG, the world's third largest automobile manufacturer. For example, in a 5-stage ion compressor developed by Linde, the piston moves up and down hydraulically, and there is an ionic liquid on the top of the piston. The ionic liquid is not combined with the gas, and it acts as a liquid piston with hydrogen through t...

Abstract

The invention belongs to the technical field of compressors, and particularly relates to a swinging reversing two-stage pressurization zero-clearance type ionic liquid compressor. Ionic liquid compressors use ionic liquid instead of metal pistons to generate high pressure under isothermal condition, however, an existing ionic liquid compressor uses 5-stage compression, and is complex in structure,difficult to machine and high in cost, so that the construction and development of a hydrogen refueling station are limited. The swinging reversing two-stage pressurization zero-clearance type ionicliquid compressor comprises a hydraulic mechanism and a gas pressurization mechanism which are mutually connected; the gas pressurization mechanism comprises a hydraulic swinging assembly, the hydraulic swinging assembly is connected with a first-stage gas pressurization assembly, and the hydraulic swinging assembly is connected with a second-stage gas pressurization assembly; and the hydraulic swinging assembly is connected with the hydraulic mechanism through a reversing assembly. According to the compressor, the structure is simple, machining is convenient, the control precision is high, the energy consumption is low, the clearance volume is zero, the universality is strong, hydrogen is not polluted and the cost is low.

Description

technical field [0001] The application belongs to the technical field of compressors, in particular to a swing reversing two-stage supercharged zero-gap ionic liquid compressor. Background technique [0002] Hydrogen is known as the clean energy with the most potential for development in this century because it only produces water and has abundant sources. Fuel cell vehicles powered by hydrogen have the advantages of environmental protection, high efficiency, zero pollution, and zero emissions. more and more attention. Therefore, as a guarantee for the hydrogen energy supply of fuel cell vehicles, the construction of hydrogen refueling stations is particularly important. However, for now, the number of hydrogen refueling stations is still difficult to form a gas supply network, and its supply capacity has become one of the bottlenecks in the promotion of fuel cell vehicles. [0003] The hydrogen refueling station is similar to the existing relatively mature compressed natu...
