Energy transfer actuator of suspension piston

Abstract

The invention discloses an energy transfer actuator of a suspension piston. The energy transfer actuator of the suspension piston comprises a cavity piston 6, a cylinder sleeve 61, an upper cylinder cover 65 and a lower cylinder cover 67, wherein an exchangeable adjusting ring 62 is arranged between an upper piston plane 661 and a lower piston plane 662 of the cavity piston 6, and the cylinder sleeve 61, the upper cylinder cover 65 and the lower cylinder cover 67 tightly fix the cavity piston 6 after wrapping the cavity piston 6. The action of the adjusting 62 is adjusting the specific gravity of the overall space of the cavity piston 6 between the specific gravity of work liquid medium and the specific gravity of waste high-pressure liquid; the structure has the advantages that a piston rod is not needed for supporting; and the cavity piston 6 can suspend between two-phase liquid, and any seal friction resistance power consumption and hidden trouble of maintenance are removed. An inner contact 63 is arranged at the inner wall of the upper cylinder cover 65, and the inner contact is connected with an external signal wire 64 led from the outer side of the upper cylinder cover 65. The action of the inner contact 63 is that a control valve switches more directly and quickly.

Description

technical field [0001] The invention belongs to the field of energy transmission equipment, and in particular relates to a suspended piston energy transmission actuator related to energy recovery equipment in a reverse osmosis seawater desalination system. Background technique [0002] Energy transfer is ubiquitous in chemical engineering, especially in the exchange of pressure in liquids. In chemical production, some waste liquids often have quite high pressure before being discharged, which will cause a lot of waste if not utilized. Energy can be obtained from the waste high-pressure fluid as a pre-pressurization of the working liquid medium, thereby saving a lot of energy costs and achieving the purpose of energy saving and emission reduction. With the advancement of science and technology, the population is increasing day by day, and people's desire to develop into the ocean is becoming stronger and stronger. Seawater desalination treatment is becoming more and more pop...

Problems solved by technology

The disadvantage is that the working liquid medium is in direct contact with the waste high-pressure liquid, which can only be limited to the occasion where the working liquid medium is the same as the waste high-pressure liquid, and there is a large flow and small diameter energy transfer, and the pipeline consumes a lot of energy; and for large pipes The energy transfer of the diameter structure, the mixing surface is difficult to control, the efficiency is low obviously, the transfer quality drops sharply, and the actual efficiency is often lower than 85%.

Generally, multiple small diameter and long pipes are connected in parallel, which appears to be a huge system, complicated project investment and difficult to manage and coordinate
