The utility model discloses the theory of reality of compressor as follows:
the chemical reaction of the fuel cell has strict requirements on parameters such as temperature, humidity, pressure and flow of air, and the common industrial compressor cannot meet the working requirements of the fuel cell. Therefore, a compressor having superior performance and a good matching with the fuel cell system is very important for the fuel cell system. The basic requirements of the air compressor special for the fuel cell engine are oil-free, high efficiency, miniaturization, low cost, low noise, small flow area of a surge line, good dynamic response capability and the like.
A turbine compressor belongs to a centrifugal compressor. The principle of pressurization is that energy is transferred to air through a high-speed impeller to enable the gas to obtain a very high speed, and then a diffuser pipe is used for reducing the flow rate of the gas and increasing the pressure of the gas. The efficiency of the compressor can reach more than 75%, and meanwhile, the compressor can provide equivalent flow rate in a small volume under the support of a high-speed motor.
When the air passes through the first turbine, the air is pressurized for the first time under the driving of the high-speed motor, flows to the second turbine through the outside of the air compressor, and is pressurized for the second time, and the process of gas pressurization is totally performed twice. Meanwhile, the motor shaft is a hollow shaft, so that the rotating speed of the motor can be effectively increased and the vibration can be reduced compared with a solid motor shaft.
The above description is only for the specific embodiments of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the scope of the present invention.
