Fluid power machine

Abstract

The invention provides a fluid power machine, belonging to power equipment. The fluid power machine comprises a water inlet and a water outlet and is characteristic in that the fluid power machine comprises a water tank, a main shaft and a piston board; the fixed water tank and the main shaft rotating at high speed can form a water cylinder, the piston board rotates around the main shaft and simultaneously enters into the main shaft or goes out of the main shaft; after the finishment that the high-pressure flow pushes the piston board to do work, the piston board gradually enters the main shaft to keep away from a core wall and then goes out of the main shaft to complete the next working cycle. The fluid power machine has the advantages that high-pressure flow can enable the propeller of the traditional water turbine to generate a rotating force and a very big useless axial thrust simultaneously, thus losing a large amount of energy; while the fluid power machine can not generate axial thrust during working, and the discharged water flow is stable and slow, so the energy of high-pressure flow can be sufficiently converted into kinetic energy.

Description

1. Technical field [0001] The fluid power machine of the present invention belongs to power equipment. 2. Background technology [0002] The energy conversion efficiency of the water turbines used in hydropower stations is very low. While the high-pressure water flow causes the propellers of the hydro turbines to generate rotational force, it also causes the propellers to generate a large useless axial thrust, and a lot of energy is lost. In addition, the water flow discharged from the turbine will generate a large eddy current, and the flow rate is too fast, which are all manifestations of energy loss. 3. Contents of the invention [0003] In view of the defects in the above-mentioned technologies, I have designed a fluid power machine, which greatly improves the energy conversion efficiency. [0004] The technical scheme that the present invention takes is as follows: [0005] This fluid power machine comprises water inlet, discharge port, is characterized in that: ...
