Summary of the invention
For effective range of raising water jet under low power condition, and keep stronger impulsive force, the utility model provides a kind of high pressure water jet cleaning device that has gas injection system.
The utility model is taked following technical scheme: high pressure water jet cleaning device; Comprise high-pressure water shot flow generating apparatus, injector head; Described injector head comprises high-pressure water shot flow nozzle, outer shroud circle cover, and the high-pressure water shot flow nozzle is communicated with through first pipeline with the high-pressure water shot flow generating apparatus, the sheathed outer shroud circle of high-pressure water jet nozzle periphery cover; The sidewall of outer shroud circle cover has peripheral circulation input port, and peripheral circulation input port is communicated with described high-pressure water shot flow generating apparatus through second pipeline; The sidewall of outer shroud circle cover has the gas injection input port, and this gas injection input port is communicated with through the 3rd pipeline with a gas injection system.
Described high pressure water jet cleaning device, the inwall of outer shroud circle cover forms many spiral grooves.
Described high pressure water jet cleaning device, gas injection system comprises air pump, air pump is communicated with through the gas injection input port of the 3rd pipeline with said outer shroud circle cover, on described the 3rd pipeline gas flow control valve is installed.
Described high pressure water jet cleaning device is equipped with liquid flow control valve on second pipeline.
Described high pressure water jet cleaning device, when injector head was in level, described gas injection input port was positioned at the place ahead or the rear of peripheral circulation input port.
In the utility model high pressure water jet cleaning device, the high-pressure water shot flow nozzle produces the high-voltage high-speed water jet.The outer shroud circle cover inner additional low pressure low speed circulation outside at the high-pressure water shot flow nozzle floods condition to form manual work.In order effectively to enlarge effective range scope of high-pressure water jet, strengthen the impulsive force of jet, the utility model has been set up a gas injection system, and it is injected into bubble in the outer shroud circle cover of high-pressure water jet nozzle periphery.Under when press water is gentle, injecting; The periphery circle cover of high-pressure water shot flow nozzle sprays low pressure low speed bubble-liquid two-phase jet; In the outlet of injector head and clean and form low-density gas-liquid two-phase environment between the target, make the high-voltage high-speed water jet pass the gas-liquid two-phase environment and arrive and clean target under water.This cleaning device has greatly reduced the penetration resistance of high-pressure water jet, the energy consumption of also having practiced thrift the water jet cleaning device simultaneously.In order to obtain more tiny bubble and uniform more gas-liquid two-phase environment; Be processed into many spiral grooves to the inwall of outer shroud circle cover; Form volute chamber; Produce vortex during current process spiral groove, this structural design helps forming more tiny bubble and uniform more gas-liquid two-phase environment.
