3615 results about "Working fluid" patented technology

For fluid power, a working fluid is a gas or liquid that primarily transfers force, motion, or mechanical energy. In hydraulics, water or hydraulic fluid transfers force between hydraulic components such as hydraulic pumps, hydraulic cylinders, and hydraulic motors that are assembled into hydraulic machinery, hydraulic drive systems, etc. In pneumatics, air or another gas transfers force between pneumatic components such as compressors, vacuum pumps, pneumatic cylinders, and pneumatic motors. In pneumatic systems, the working gas also stores energy because it is compressible. (Gases also heat up as they are compressed and cool as they expand; this incidental heat pump is rarely exploited.) (Some gases also condense into liquids as they are compressed and boil as they expand.)

Reactor for catalytically oxidizing wastewater through ozone and application method thereof

The invention discloses a reactor for catalytically oxidizing wastewater through ozone and an application method thereof. The reactor comprises a reaction chamber, a water inlet, a water outlet, a gasoutlet and a circulating water outlet, wherein a separation plate in the reaction chamber is used for separating the lower part of the reaction chamber into a jet flow reaction chamber and a tower type reaction chamber; the jet flow reaction chamber is internally provided with a first catalysis bed layer and an ejector; the circulating water outlet is connected with a working fluid inlet of the ejector; the gas outlet is connected with a sucked liquid inlet of the ejector through a gas circulating pipe; the water inlet is arranged at the bottom of the jet flow reaction chamber; the tower typereaction chamber is internally provided with a tower plate and a second catalysis bed layer; the water outlet is arranged at the bottom of the tower type reaction chamber; a gas inlet is communicatedwith the lower side of the tower plate and the gas circulating pipe; the gas circulating pipe is connected with a tail gas outlet. The reactor has the advantages of high mass transfer efficiency, rapid reaction speed, high ozone utilization rate, high COD (Chemical Oxygen Demand) removal rate and the like.

Method and apparatus for converting thermal energy to mechanical energy

A method and apparatus for converting thermal energy to mechanical energy which can use a wide range of fuels and perform with a high efficiency. Operating on a little utilized thermodynamic cycle of isentropic compression, isothermal expansion, isentropic expansion and finally constant pressure cooling and contraction. The external heat engine utilizes a heat exchanger carrying heat from the external energy source to the working parts of the engine. Pistons and cylinders are activated by appropriate means to adiabatically compress the working fluid, for example ambient air, to transfer the entire mass of the air through the heat exchanger to accomplish isothermal expansion followed by adiabatic expansion and, finally, exhaust the air to ambient to allow for constant pressure cooling and contraction. Valve pistons in conjunction with the cylinders form valves that allow for the exchange of working fluid with ambient. Energy is added to the engine during isothermal expansion, whereby the energy of compression is added by a flywheel or other appropriate energy storage means, said flywheel stores energy recovered during adiabatic expansion. The thermodynamic cycle described and the engine embodiments disclosed, when run in reverse, perform as a heat pump or refrigeration device.
