Embodiment Construction
[0012] The following embodiments illustrate the present invention more clearly and completely in conjunction with the accompanying drawings.
[0013] figure 1 A decompression energy recovery system for an air motor is shown. This system, which can recover the high-pressure air decompression energy of the air motor, works in the following way: the high-pressure gas flows out from the air storage tank 1 through the nozzle 2 and becomes high-speed flowing low-pressure gas and enters the expander 3 to do work on it, and the energy passes through the transmission 9 Passed to the compressor 8. After doing work, the gas enters the heat exchanger 4 from the outlet to exchange heat with the external environment, and enters the surge tank 5 after the temperature rises to the ambient temperature.
[0014] The fresh air enters the compressor 8 to be compressed after being filtered by the filter 7 to increase the air pressure and the air temperature, and then directly enters the surge ta...

A pressure reduction energy recovery system for a pneumatic motor differs from a currently-used throttling pressure reduction type or positive-displacementpressure reduction system and is a system capable of recovering energy released when the pressure of high-pressure gas is reduced to operation pressure. The pressure reduction energy recovery system with the structural type is simple in structure. An electric control system can open or close a solenoid valve to control flow of compressed gas and pressure of operation gas in a pressure stabilizing tank according to needs of the pneumatic motor. Timely adjustment can be carried out along with gradual reduction of continuous output pressure of the compressed gas so that pressure reduction energy can be recovered almost in the whole process, energy output and mechanical efficiency of the system are improved, and stable inlet pressure of the pneumatic motor can be ensured simultaneously. Therefore, the pressure reduction energy recovery system solves the problem of energy loss in pressure reduction of the high-pressure gas, is favorable for popularization and application, and has wide market prospects.
Description
technical field [0001] The invention relates to a decompression energy recovery system for an air motor, which is different from the currently used throttling decompression or volumetric decompression systems, and is a kind of energy recovery system that can recover high-pressure gas released when it is decompressed to the working pressure. energy system. Background technique [0002] Due to the problem of energy density, the gas storage pressure of the current air motor is relatively high, usually around 15.0-30.0, and the actual working gas pressure is usually not more than 1.0MPa or even lower, so we need a decompression system to reduce the gas pressure. pressure to facilitate its work. At present, the most widely used decompression system on air motors is the throttling decompression system, and the volumetric decompression system is a new decompression system that has just been proposed recently. Both systems are applied to the air motor, which makes the gas in the g...
