Power apparatus with temperature difference as energy

Abstract

The invention relates to a temperature differential energy power plant which forms pressure source by temperature changes of working substances and generates pressure difference. The power plant solves the disadvantages that channel accuracy of a convection cell is higher and processing difficulty is increased in the prior art. The power plant comprises a rotating shaft arranged on a support, the rotating shaft is provided with a fluid channel by a spoke, working cavities are arranged in the fluid channel, unidirectional opening devices are arranged among the working cavities, and the fluid channel is internally preassembled with pressure balancing liquid; an inlet manifold and an exhaust manifold are arranged on the spoke between the rotating shaft and the fluid channel, and the parts connecting with the fluid channel are respectively provided with a control solenoid valve; one end of the rotating shaft is connected with a steam generator by an air inlet pipe, and the other end of the rotating shaft is connected with a condenser by an exhaust pipe. Check valves are used to separate the working cavities and pressure differences is generated at the check valves, which causes the structure of the plant to be simple, and can realize good sealing effect among the working cavities, thus being capable of reducing the processing accuracy of the fluid channel.

Description

technical field [0001] The invention relates to a fluid engine, in particular to a temperature difference energy power device which forms a pressure source through the change of temperature difference of working medium and generates pressure difference. Background technique [0002] Commonly used fluid engines are sliding vane hydraulic motors, gear hydraulic motors, etc. The sliding vane hydraulic motor is mainly composed of a volute, a sliding vane, a rotor, a rotating shaft, and an end cover. The fluid flows in from the inlet of the sliding vane hydraulic motor. , because there is a pressure difference between the front and back of the slide vane, driven by the pressure difference, the slide vane transmits the pressure to the rotor, so that the rotor and the rotating shaft rotate, and the fluid flows out from the outlet of the slide vane hydraulic motor, so the fluid The pressure potential energy is converted into the total mechanical energy output by the rotation of the ...
