In the presence of be adjacent to the inner surface of cylinder body 1, liquid flows to low pressure flow-out hole 10 and discharged, i.e., left chamber 11 can realize the pressure of fluid
The kinetic energy of rotor 5 and slide plate 6 can be converted into；On right side, gas enters right chamber room 8 from low pressure flow-in hole 9, and rotor 5, which rotates, to be driven
Slide plate 6 moves, and slide plate 6 promotes fluid to flow in the right chamber room 8, with the change of cavity volume, working chamber sectional area first increases and then decreases,
The breathing process and compression process of corresponding gas, pressure increases gas after compression, from the row of high pressure flow-out hole 4 after gas boosting
Go out, i.e., right chamber room 8 can realize that the kinetic energy of rotor 5 and slide plate 6 is converted into the pressure energy of fluid.Generally speaking, energy path for transformation
For：The pressure energy of pressure energy-rotor 5 of highly pressurised liquid and kinetic energy-low-pressure gas of slide plate 6, pass through the different phase stream stock
Between hydraulic recovery equipment, realize highly pressurised liquid supercharging low-pressure gas process, realize the recycling of fluid overbottom pressure.
In summary, the hydraulic recovery equipment between different phase stream stock disclosed by the invention, including cylinder body, rotor, slide plate,
The rotor is arranged on inner chamber of cylinder block room, forms left and right working chamber respectively in both sides, is provided with some conduits on rotor, in conduit
