Beneficial effect of the present invention is mainly manifested in: fast, the recyclable pressurized gas of aeration speed, cost are low.
Description of drawings
The schematic diagram of the quick high-pressure gas charging system that but Fig. 1 is energy to be reclaimed.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
With reference to Fig. 1, but the quick high-pressure gas charging system that a kind of energy reclaims, comprise accumulator 22, described quick high-pressure gas charging system also comprises fuel tank 1, singly go out rod oil cylinder 10 and gas-liquid cylinder 13, the oil outlet of described fuel tank 1 is by oil hydraulic pump 4, one-way valve 5 is connected with three position four-way directional control valve 7, the return opening of described fuel tank 1 is connected with three position four-way directional control valve 7 by relief valve 6, described three position four-way directional control valve 7 is communicated with the 8 described rodless cavities that singly go out rod oil cylinder 10 by the plug-in mounting one-way valve, the described the other end that singly goes out the piston rod of rod oil cylinder 10 is installed in an end of connecting rod, described connecting rod and piston rod are arranged vertically, the other end of described connecting rod is installed the loading pouring weight 12 that moves to rodless cavity in order to drive piston, the described rod chamber that singly goes out rod oil cylinder 10 is communicated with the liquid container of described gas-liquid cylinder 13, the air inlet/outlet of the air chamber of described gas-liquid cylinder 13 is by safety valve 20, pressure relay 21 is connected with described accumulator 22, air inlet/outlet while and the Aspirating valves 14 of the air chamber of described gas-liquid cylinder 13, pneumatic shuttle valve 16 is connected connection with air-strainer.
Further, the described rod chamber that singly goes out rod oil cylinder 10 is connected with bi-bit bi-pass selector valve 9, and described bi-bit bi-pass selector valve 9 is connected with described three position four-way directional control valve 7.
Further, describedly singly go out the internal diameter of rod oil cylinder 10 greater than the internal diameter of described gas-liquid cylinder 13.
Described pneumatic shuttle valve 16 is connected with the first manual ball valve 17 that is used for the recovery residual pressure.
Oil hydraulic pump 4 is driven by motor 3, and approach switch 11 is installed on the described connecting rod, and the second manual ball valve 18, the 3rd manual ball valve 19 are installed on the pipeline between the air inlet/outlet of the air chamber of described gas-liquid cylinder 13 and the safety valve 20; The 4th manual ball valve 23 is installed in the outlet of described accumulator 22.
In the present embodiment, during system works, selector valve 7 right electromagnet get electric, the right position of selector valve, pressure oil enters the cavity of resorption that singly goes out rod oil cylinder 10, its epicoele oil pressure is entered the cavity of resorption of gas-liquid cylinder 13, the air of pressurized gas fluid cylinder 13 epicoeles, when gas pressure surpassed the inflation pressure of safety valve 20, the pressurized gas of gas-liquid cylinder 13 epicoeles was pressed in the accumulator 22.Then, selector valve 7 right electromagnet dead electricity, the selector valve meta, oil hydraulic pump 4 off-loads, plug-in mounting one-way valve 8 is opened, under the Action of Gravity Field that loads pouring weight, the hydraulic oil that singly goes out the cavity of resorption of rod oil cylinder 10 is got back to fuel tank, simultaneously, the hydraulic oil of gas-liquid cylinder 13 cavity of resorptions enters into the epicoele that singly goes out rod oil cylinder 10, and gas-liquid cylinder is by air filter 15, pneumatic shuttle valve 16 and Aspirating valves 14 epicoele with atmosphere inhaling air fluid cylinder 13, when the piston rod of oil cylinder 10 is return when putting in place, approach switch 11 sends signal, selector valve 7 right electromagnet is got electric, begins next accumulation of energy process.After certain high-voltage pulse water cannon emission, the cavity of resorption of transmission cylinder still has higher residual pressure, and the pressurized gas of transmission cylinder cavity of resorption enter the epicoele of gas-liquid cylinder 13 through manual ball valve 17, shuttle valve 16 and Aspirating valves 14, and promote quick oil return, thereby realizes that energy reclaims.Through behind the gas replenishment process to accumulator 22 repeatedly, when reaching the setting pressure of pressure relay 21, selector valve 7 dead electricity, the pump off-load, thermal energy storage process finishes.After the long-term work, owing to can not arrive topmost when leaking the piston gas-pressing cause gas-liquid cylinder 13, open bi-bit bi-pass selector valve 9 and carry out repairing.In addition, when the internal diameter of oil hydraulic cylinder 10 during greater than gas-liquid cylinder 13 internal diameter, pressurization is arranged, can make the pressure in the accumulator 22 be higher than oil supply pressure.
