Abstract

The invention relates to a piston type expander with adjustable expansion ratio, which comprises a casing and a cylinder head arranged at one end of the casing. The inside of the casing rotates coaxially and is provided with a rotating cylinder close to the cylinder head. A number of piston holes are evenly arranged on the rotating cylinder around the circumference in the axial direction, and a freely movable piston is arranged in the piston hole, and a steam inlet that can be connected with any piston hole in turn is arranged on the cylinder head. Pipe and exhaust pipe, one end of the rotating cylinder is centrally set through the cylinder head with a rotating cylinder shaft, and the inside of the casing is also provided with an adjustable swash plate that can move axially, and the adjustable tilt The inclined surface at one end of the disk is in contact with the inclined surface of the piston sliding shoe at one end of the piston, and the other end of the adjustable swash plate is provided with an adjustment mechanism that drives the adjustable swash plate to move axially. The present invention adjusts the distance between the piston and the cylinder head through the linkage mechanism, thereby adjusting the volume of the steam inlet and achieving the effect of adjusting the expansion ratio of the expander.

Description

technical field [0001] The invention relates to the field of expanders, in particular to a piston expander with adjustable expansion ratio. Background technique [0002] The expander is a machine that utilizes the expansion of gas with a certain pressure to output mechanical work. It is mainly used for the recovery of low-grade energy. The externally output mechanical work of the expander can drive a generator to generate electricity, and can also directly drive mechanical equipment. The expander and the compressor are named according to different conditions of use or functions. The condition of use of the compressor is driven by power, and its function is to compress low-pressure gas into high-pressure gas; the condition of use of the expander is to pass in high-pressure gas , get low-pressure gas from the outlet, and push the rotor to rotate, its function is to output power outward. [0003] Expanders are generally divided into two types according to the operating mode: o...
