A sliding vane expansion machine

Abstract

The invention provides a sliding vane type expansion working machine. The working machine comprises a shell, a revolving shaft, clamping slots, a spring, a sliding slice, an air inlet pipe and an exhaust pipe, wherein the shell is of an oval structure, the length of a short shaft of the shell is equal to that of the diameter of the revolving shaft, and the same circumference of the external surface of the revolving shaft is provided with a plurality of clamping slots; the clamping slots are symmetrically distributed, one end of the spring is fixedly connected with the bottoms of the clamping slots, and the other end of the spring is connected with one end of the sliding slice; the other end of the sliding slice is contacted with the inner surface of the shell, the interior of the shell is divided into an upper working cavity and a lower working cavity by virtue of the revolving shaft, and the air inlet pipe and the exhaust pipe are respectively communicated with the two sides of the working cavity. The sliding vane type expansion working machine has the advantages that an expansion machine with a fixed volumetric ratio is high in expansion isentropic efficiency, the homocentric design of the revolving shaft and the shell has the advantages of slight vibration, low side pressure, small friction and volume, capability of rapidly operating and the like, the whole machine structure is high in reliability and low in manufacturing cost, and the working effects such as high-temperature gas resistance and high isentropic expansion efficiency are realized.

Description

technical field [0001] The invention belongs to the field of expansion work machines, and in particular relates to a sliding vane expansion work machine. Background technique [0002] The expander is a machine that uses the principle of outputting mechanical work to reduce the temperature of the gas when the compressed gas is expanded and depressurized to obtain energy. [0003] The expansion work machine mainly uses the turbine to perform expansion work. This structure mainly has the advantages of simple structure and large power output. However, this structure also has disadvantages such as unbearable high temperature and low isentropic expansion efficiency. Technical personnel need further research and development to be more efficient. A new type of expansion power machine that can withstand high temperatures and meet actual production needs. Contents of the invention [0004] The problem to be solved by the invention is to provide a sliding vane type expansion power m...
