Kerosene sealing test system with gas-liquid boosting pump

Abstract

The invention discloses a kerosene sealing test system with a gas-liquid boosting pump, which comprises a gas source pressure regulating valve, wherein the gas source pressure regulating valve and the gas-liquid boosting pump are provided with a gas source pressure meter therebetween, the gas-liquid boosting pump is connected with an oil tank through an oil absorbing filter, the output end of the gas-liquid boosting pump is connected to a system pressure meter, a high-pressure reducing valve and a low-pressure reducing valve, the high-pressure reducing valve is connected to a high-pressure reducing valve outlet stop valve, the low-pressure reducing valve is connected to a low-pressure reducing valve outlet stop valve, the output ends of the high-pressure reducing valve outlet stop valve and the low-pressure reducing valve outlet stop valve are connected to an unloading valve and a pressure maintaining test valve, the pressure maintaining test valve is connected to a workpiece, a low-pressure test pressure meter and a low-pressure test pressure meter switching valve, and the low-pressure test pressure meter switching valve is connected to a high-pressure test pressure meter. The kerosene sealing test system with the gas-liquid boosting pump has the advantages of small size, no power supply, low power consumption, zero leakage, explosion prevention, safety, reliability, simple operation and the like.

Description

technical field [0001] The invention relates to the technical field of testing equipment, in particular to a kerosene sealing testing system with a gas-liquid booster pump. Background technique [0002] With the continuous development and updating of military equipment, such as aircraft engines and automobile engines, the performance is continuously improved, and the operating pressure is getting higher and higher. When injecting oil from aircraft nozzles and engine nozzles, the oil needs to be atomized, compressed, and ignited under high pressure. Expansion work. This requires no leakage of the nozzle under high pressure. If the leakage will reduce the atomization pressure, oil leakage, lower efficiency, incomplete oil atomization, insufficient combustion, insufficient horsepower, pollution of the environment, and even serious Lead to equipment failure and accidents. This requires a sealing test after the nozzle is produced to avoid accidents. [0003] At present, this typ...

Problems solved by technology

The motor pump unit will generate heat and consume electricity for a long time. The design oil tank volume increases, and it is necessary to equip coolers and other equipment, which is unsafe when testing flammable and explosive liquids. Low efficiency: the efficiency of the motor can only reach 80%. Electromagnetic The valve and the pressure regulating valve are slide valve structures, which have internal leakage, which affects the authenticity of the test results. They are not resistant to kerosene corrosion: the pipeline is connected by rubber seal, which is easy to corrode, etc.

Most of the kerosene pumps rely on imports, which are expensive, economically weak, and difficult to maintain. Moreover, the hydraulic system is bulky and has low adaptability. It is far from meeting the needs of modern equipment.
