Star-type high-low pressure power machine and work-doing method of star-type high-low pressure power machine

Abstract

The invention relates to a star-type high-low pressure power machine which comprises a heat collector, a heat preservation pipe, a gasification reactor, an atomizer, air cylinders, a piston, a piston ring, an automatic air exhaust valve, a radiator, a liquid storage tank, a pressure valve, a connecting rod, a crank shaft, a heat preservation layer, a rotating shaft and a machine shell. The five air cylinders are arranged on the machine shell and surround the crank shaft in a star-type mode, the piston is connected to the crank shaft through the connecting rod, the air cylinders include the three low-pressure air cylinders and the two high-pressure air cylinders, two low-pressure air cylinders are arranged in parallel, and the third low-pressure air cylinder is arranged between the two high-pressure air cylinders. The star-type structure of the star-type high-low pressure power machine is large in rigidity, light in weight, good in reliability, maintainability and survivability, large in power growth potential and high in rotating speed, displacement and power can be improved by increasing the diameters of the air cylinders, working media are recycled, pollution is avoided, the heat energy conversion efficiency is 65%-98%, conventional energy consumption can be replaced, the economic benefit is high, energy conservation and environmental protection are achieved, and noise is low.

Description

technical field [0001] The invention belongs to the field of high and low pressure power machines, especially a power machine that converts heat energy such as solar energy, geothermal heat, high-temperature gas generated by combustible combustion, internal combustion engine heat or tail gas, and high-temperature gas discharged from factories into kinetic energy. Background technique [0002] Traditional power equipment includes steam engine, internal combustion engine and external combustion engine. [0003] Steam engine: Inseparable from the boiler, the whole device is bulky and bulky; the pressure and temperature of the fresh steam cannot be too high, the exhaust pressure cannot be too low, and the thermal efficiency is difficult to improve; it is a reciprocating machine, and the inertia limits the increase of the speed; The working process is discontinuous, and the flow of steam is limited, which limits the improvement of power. [0004] Internal combustion engine: comp...
