Problems solved by technology

In the production system, our quality department checks the appearance or the report provided by the manufacturer for the inspection of the air compressor. It cannot detect the key performance by itself. This method has certain product quality control risks and cannot be guaranteed by actual data. The rationality of the product, the cause of subsequent problems cannot be found, and our rights cannot be guaranteed; in addition, the poor operation of the air compressor on the system will damage other components, such as the stack. In terms of inspection efficiency, the quality department needs to be able to quickly To determine its eligibility is not to study, so it is very important to design an air compressor equipment suitable for incoming material inspection

Abstract

The invention discloses a hydrogen fuel cell air compressor detection device, and relates to the technical field of hydrogen fuel cell air compressor detection. The upper-layer air compressor installation and auxiliary part structure is arranged on the top layer of the overall rack and used for detection, the lower-layer cooling structure is arranged on the bottom layer of the overall rack and used for cooling, and the upper computer system is arranged on the side face of the overall rack and used for control. The upper-layer air compressor installation and auxiliary part structure comprises an air compressor to be tested and a galvanic pile simulator which are fixed on the integral rack through a clamp, an air inlet of the air compressor to be tested is connected with a flow meter, the other end of the flow meter is connected with an air filter through a first rubber pipe, an air outlet of the air compressor to be tested is connected with an intercooler through a first rubber pipe, and the intercooler is connected with the galvanic pile simulator through a second rubber pipe. An air outlet of the intercooler is connected with a humidifier through a first rubber pipe, and a humid air outlet of the humidifier is connected to the air inlet end of the galvanic pile simulator through a first rubber pipe. According to the invention, the inspection efficiency is relatively high while the inspection requirement is met.

Description

technical field [0001] The invention relates to the technical field of hydrogen fuel cell air compressor detection, in particular to a hydrogen fuel cell air compressor detection device. Background technique [0002] If the fuel cell stack is the "big heart" of the fuel cell power system, then the air compressor is the powerful "lung". The high-performance output of the fuel cell system requires a strong "heart-lung function"; The air compressor is the most core key component in China except for the fuel cell stack. Although the design method of the fuel cell air compressor is similar to that of the traditional internal combustion engine supercharger, there is a big difference between the two in the use environment, working range and requirements. Air compressors for fuel cells need to meet the characteristics of oil-free, low noise, low cost, miniaturization, wide working range, and fast dynamic response. To some extent, air compressors for fuel cells represent the highest...
