Prime mover, acting method and hydraulic turbine set

Abstract

The invention belongs to prime movers, and particularly relates to a prime mover, an acting method and a hydraulic turbine set. The prime mover comprises an evaporator, a machine body and an energy body, wherein the energy body is arranged in the machine body in a sliding mode, a cavity is formed between the bottom of the energy body and the inner wall of the machine body, a telescopic inner container is arranged in the cavity, and the evaporator communicates with the inner container. The evaporator continuously absorbs heat to evaporate a liquid working medium to push the energy body to moveupwards to do work till the upper limit stroke is reached, and when the environment temperature meets the liquefaction temperature, the energy body moves downwards due to the dead weight to compress agaseous working medium to complete liquefaction. The evaporator is arranged to evaporate the liquid working medium, the volume expands to push the energy body to move upwards to do work, and mechanical energy is output; and when the environment temperature meets the set value of the liquefaction stroke, the gaseous working medium is compressed through the dead weight of the energy body to performthe liquefaction stroke, the inner container is arranged, on the premise that the energy body and the machine body do not need to be sealed in a sliding mode, the sealing performance is greatly improved, the manufacturing difficulty and cost are reduced, and positive economic value is achieved.

Description

technical field [0001] The invention belongs to a prime mover, and in particular relates to a prime mover, a work method and a water turbine unit. Background technique [0002] Prime mover refers to all machinery that uses energy to generate motive force. It is the main source of power required in the fields of modern production and life. [0003] At present, in the equipment that converts air heat energy into mechanical energy, the working fluid with low evaporation temperature is generally used to absorb heat and expand to do work. However, this kind of evaporation from liquid to gas requires special mechanical equipment to complete, and the gaseous working fluid returns to liquid. It also requires Use other equipment to compress the gaseous working medium or increase the exhaust pressure to complete it. This method will reduce the working pressure difference and reduce the work. For example, the gaseous working medium is compressed into a liquid state by a compression ma...

Problems solved by technology

In this invention, it is necessary to depressurize through the expansion mechanism 15 and evaporate through the first evaporator 16. After the evaporation occurs and expands to perform work on the rotary vane power machine 17, it is then compressed back to the first condenser 13 through the generating state working fluid compressor 12. Circulation, in the circulation path of doing work, the evaporation and liquefaction of the refrigerant requires the expansion mechanism and the generating gas working medium compressor 12 respectively, which increases the cost and consumes a large amount of kinetic energy or electric energy, resulting in a waste of energy and cannot generate economic benefits. At the same time, with the design of this kind of circulation pipeline, the refrigerant flow path is long, and part of the energy will be lost on the way, which will also cause energy loss
