Description of drawings
Fig. 1 is the supercharging device structural representation of emulsion valve integration test testing table.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail
As shown in Figure 1, this supercharging device of the utility model is made up of hydraulic booster pumping plant and pressurizing cylinder 13, the hydraulic booster pumping plant is installed on the right support of integration test testing table main liquid box, be made up of fuel tank 1, vacuum switch 3, oil pump 4, actuating motor 5, retaining valve 6, filter-press 8, tensimeter 11, solenoid directional control valve 12, pressure switch 10, safety valve 9, proportional dump valve 7, hydraulic pressure air strainer 2, oil suction filtrator 16, the inlet port that oil suction filtrator 16 is positioned at fuel tank 1 and oil pump 4 links to each other; Be used to protect oil pump 4 to be without prejudice.Vacuum switch 3 is in normally open and links to each other with oil suction filtrator 16 delivery outlets; When oil suction filtrator 16 took place to stop up, vacuum switch 3 was reported to the police, and prompting operation person is renew cartridge more.Oil pump 4 exits link to each other with retaining valve 6; Be used to prevent that the fluid refluence from damaging oil pump 4.Retaining valve 6 links to each other with filter-press 8; Filter-press 8 links to each other with solenoid directional control valve 12 by tensimeter 11; Actuating motor 5 drives oil pump 4 rotations, makes the right-hand member of solenoid valve 12 charged, oil pump 4 sucks hydraulic oil in fuel tank 2, and, carrying out high-pressure filteration through filter-press 8 becoming high-voltage oil liquid from fuel tank 1 interior next low pressure fluid supercharging, the pressure index after the filtration is presented on the tensimeter 11.Tensimeter 11 is connected with proportional dump valve, and high-voltage oil liquid carries out pressure regulation through proportional dump valve 7, makes the requirement of the output pressure applicable system of high-voltage oil liquid, and the Comparative Examples voltage-regulating system provides ratio pressure regulation power.It provides supercharging power can for pressurizing cylinder 13.
Above-mentioned pressurizing cylinder 13 is by being installed on the integration test testing table main liquid box fore-stock, by charged piston 17, O-ring seal 18, retaining valve 14, retaining valve 15 are formed, wherein, O-ring seal 18 is divided into oil pocket and emulsification sap cavity with pressurizing cylinder 13, and retaining valve 14 and retaining valve 15 are embedded in in-oil cylinder delivery outlet, by the effect of hydraulic booster pumping plant, it can export the emulsion up to 70MPa pressure, uses for test.
Above-mentioned solenoid directional control valve 12 is connected with pressurizing cylinder 13 input ports; The direction that control fluid enters pressurizing cylinder 13 makes pressurizing cylinder 13 finish the supercharging of emulsion.High-pressure and hydraulic oil enters the oil pocket of pressurizing cylinder 13 from solenoid directional control valve 12 after proportional dump valve 7 is transferred to convenient pressure, the charged piston that promotes pressurizing cylinder moves right, and makes the low pressure emulsion of emulsification sap cavity become high-pressure emulsion from retaining valve 15 outputs.When the charged piston of pressurizing cylinder 13 moves to low order end, pressure switch 10 senders, solenoid directional control valve 12 left ends get, hydraulic oil enters pressurizing cylinder 13 emulsification sap cavities, promote charged piston to left movement, make the emulsification sap cavity of pressurizing cylinder 13 form vacuum and suck emulsion simultaneously by retaining valve 14.When the charged piston of pressurizing cylinder 13 moves to high order end, pressure switch 10 senders, solenoid directional control valve 12 right-hand members get, hydraulic oil enters pressurizing cylinder 13 oil pockets, the promotion charged piston moves right, and makes the low pressure emulsion of pressurizing cylinder 13 emulsification sap cavities become high-pressure emulsion from retaining valve 15 outputs simultaneously.So repeatedly, finish the supercharging output of emulsion.Between above-mentioned oil pocket and the emulsification sap cavity direction of motion that the O-ring seal interlayer is used to control charged piston is set, prevents fluid and emulsification liquid phase string effectively.Principle is similar to the pot type piston fuel tank, by the supercharging power that the hydraulic booster pump provides, makes the emulsion of low pressure become high-pressure emulsion output, can export the emulsion up to 70MPa pressure, uses for test.
9 pairs of total systems of above-mentioned safety valve play the safeguard protection effect, are used for preventing that the maloperation hypertonia from causing damage to equipment.
Above-mentioned pressure switch 10 is used to control the piston motion direction in the pressurizing cylinder 13.
