Description
Technical field
The utility model relates to the Pneumatic hydraulic device, relates in particular to a kind of spraying system high pressure generating apparatus of gas-liquid pressure-boosting.
Background technology
The common method that existing high pressure fuel injector testing stand produces high pressure fuel is directly to utilize motor to be power, drives high-pressure oil pump work.Like this, at first will be equipped with power supply, if electric power system fault takes place, work then can't make an experiment; Secondly,, may produce electric arc and spark, can not use in possible hazardous area owing to use power drives; Once more, need be aided with complicated control device and control the pressure oscillation that high-pressure oil pump produces, and pressure oscillation is difficult for regulating; In addition, because relevant device is more, cost is high relatively, and the maintaining expense is high equally relatively.
Summary of the invention
The purpose of the utility model is the deficiency that overcomes prior art, and a kind of spraying system high pressure generating apparatus of gas-liquid pressure-boosting is provided.
The spraying system high pressure generating apparatus of gas-liquid pressure-boosting comprises compressed nitrogen gas cylinder, pressure regulator valve, hand valve, two-position five-way valve, gas-liquid pressure-boosting pump, high pressure check valve, low pressure check valve, high-pressure buffer device, high pressure needle valve and fuel injector; Compressed nitrogen gas cylinder, pressure regulator valve, hand valve, two-position five-way valve, gas-liquid pressure-boosting pump, high pressure check valve, high-pressure buffer device, high pressure needle valve link to each other with fuel injector in order, are provided with low pressure check valve at gas-liquid pressure-boosting pump and high pressure check valve junction.
The effect of the utility model is the need of work that can satisfy spray testing.Use the utility model, need not power supply, adopt gas-powered; No electric arc and spark use handling safety, and the maximum fuel output pressure can reach 300Mpa; In the pressure limit of pump, regulate input air pressure thereby regulate pressure regulator valve, the output fuel pressure is corresponding to obtain electrodeless adjustment; Therefore the output pressure fluctuation is less, and is easy to regulate.The utility model converts on the basis of gas liquid pressurization system, and relevant device is few, and is with low cost, easy to operate, and maintenance for ease of maintenaince.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Accompanying drawing 1 is the principle schematic of the spraying system high pressure generating apparatus of the utility model gas-liquid pressure-boosting;
Among the figure: compressed nitrogen gas cylinder 1, pressure regulator valve 2, hand valve 3, two-position five-way valve 4, gas-liquid pressure-boosting pump 5, high pressure check valve 6, low pressure check valve 7, high-pressure buffer device 8, high pressure needle valve 9, fuel injector 10.
The specific embodiment
Shown in accompanying drawing, the spraying system high pressure generating apparatus of gas-liquid pressure-boosting comprises compressed nitrogen gas cylinder 1, pressure regulator valve 2, hand valve 3, two-position five-way valve 4, gas-liquid pressure-boosting pump 5, high pressure check valve 6, low pressure check valve 7, high-pressure buffer device 8, high pressure needle valve 9 and fuel injector 10; Compressed nitrogen gas cylinder 1, pressure regulator valve 2, hand valve 3, two-position five-way valve 4, gas-liquid pressure-boosting pump 5, high pressure check valve 6, high-pressure buffer device 8, high pressure needle valve 9 and fuel injector 10 link to each other in order, are provided with low pressure check valve 7 in gas-liquid pressure-boosting pump 5 and high pressure check valve 6 junctions.
The continuous supercharging of the circulation of gas-liquid pressure-boosting pump 5 can realize control by a two-position five-way valve 4; The first step, two-position five-way valve 4 is in reset mode, and the cylinder piston right side in the gas-liquid pressure-boosting pump 5 is communicated with atmosphere; Cylinder piston left side in the gas-liquid pressure-boosting pump 5 is communicated with compressed nitrogen; Cylinder in the gas-liquid pressure-boosting pump 5 moves to right and resets at this moment, and the hydraulic cylinder piston that drives simultaneously in the gas-liquid pressure-boosting pump 5 moves right, in the process of the fuel oil in fuel tank low pressure check valve 7 inhalant liquid cylinder pressures; In second step, two-position five-way valve 4 is in commutation states, and the cylinder piston left side in the gas-liquid pressure-boosting pump 5 is communicated with atmosphere; The cylinder piston right side is communicated with compressed nitrogen, and cylinder moved to left and promoted hydraulic cylinder piston and be moved to the left the fuel oil in the compression hydraulic cylinder this moment; Through high pressure check valve 6, through high-pressure buffer device 8, when pressure reaches the setting pressure of high pressure needle valve 9; High pressure needle valve 9 is opened, fuel injector 10 ejection high pressure fuels; Accomplished a work period so, gone round and begun again then and realize the continuous supercharging of circulation.
The spraying system high pressure generating apparatus of this gas-liquid pressure-boosting uses compressed nitrogen to be power source, is pressure source with the gas boosting pump, and output fluid pressure is pressed into ratio with the driving source of the gas.Through to driving the adjusting of bleed pressure, just can obtain stable fluid pressure after the corresponding supercharging.Connect the initial stage at compressed nitrogen, circulation rate is the fastest, and the output fuel flow is maximum.Along with the raising gradually of output pressure, the resistance that the internal pressurization pump piston bears is also increasing, and the circulation rate of pump is also more and more slower.When the reaction force of output pressure and gas-powered power reach balance, system will stop automatically.This is that system is in packing state and consumed energy not, so it provides a kind of power source of economy.
