Welded corrugated pipe type work doing unit of heat engine

Abstract

The invention relates to the technical field of heat engine devices, in particular to a welded corrugated pipe type work doing unit of a heat engine. The welded corrugated pipe type work doing unit of the heat engine comprises a heater, a welded corrugated pipe, a cooling device, a rack, a hinged support and a transmission mechanism. The rack is formed by welding a square steel plate to supporting legs. The welded corrugated pipe is composed of a hollow metal pipe, a top end plate and a bottom end plate. The upper end of the hollow metal pipe is connected with the top end plate, and the lower end of the hollow metal pipe is connected with the bottom end plate. The bottom end plate is installed on the top of the square steel plate. The cooling device is installed at the bottom of the square steel plate. The heater is installed around the outer pipe wall of the hollow metal pipe. The top end plate is connected with the transmission mechanism through the hinged support. A gas medium is fed into an inner cavity of the hollow metal pipe. According to the welded corrugated pipe type work doing unit of the heat engine, because the non-frictional type welded corrugated pipe is used for replacing an air cylinder and piston structure, the problems of seal, lubrication, friction resistance and the like between an air cylinder and a piston are solved, and the machining difficulty and the production cost are lowered.

Description

technical field [0001] The invention relates to the technical field of heat engine equipment, in particular to a welded bellows heat engine work unit. Background technique [0002] The current heat engines are mainly divided into internal combustion engines and external combustion engines. No matter what kind of heat engine it is, the cylinder and piston are the key work units in the whole system; factors such as material selection, processing and machining accuracy of the cylinder and piston directly affect the system. Sealing, lubrication, medium leakage and energy consumption, etc., and these factors directly determine the working efficiency and service life of the heat engine; the processing difficulty of the cylinder and piston is relatively high, resulting in increased production costs. Contents of the invention [0003] In order to overcome the technical deficiencies of the existing heat engine work unit, the present invention provides a welded bellows type heat eng...
