The wind pressure of press is no more than 5000pa under normal circumstances, when the liquid in mixing liquid chamber 12 is gradually filled with, high speed rotation
Centrifugal fan impeller 4 be submerged in a liquid, liquid in the channel of centrifugal fan impeller 4 with the air winding up of sucking
It is dished out together by impeller, realizes gas-liquid mixed, the fluid of gas-liquid mixed state forms circular ring shape mixing within the scope of impeller periphery
Layer, the gas in mixed layer is mixed in air bubble-shaped with liquid.Since the density of gas is much smaller than fluid density, thus it is mixed
It closes the bubble floating of layer and is separated with liquid, finally floated in gas chamber 13, form compressed gas layer.When gas-liquid floats
When, the downward liquid flow close to inner walls is filled because gas-liquid mixed stream rises the space left and flows into centrifugal fan leaf
It takes turns in fluid channel, repeats last motion process, complete a circulation.4 continuous rotation of centrifugal fan impeller, air connect
Continuous to be inhaled into and be gathered in gas chamber 13, liquid continues through impeller rotation in liquid chamber and mixes with air, accelerate,
It dishes out, separate, continuous shuttling movement causes the indoor air accumulation of the air chamber of shell more and more, and pressure is gradually increased, from
And high pressure gas is generated, it is discharged by escape pipe 11, for gas load.
In the course of work of the invention, since the indoor compressed gas of air chamber is connected to liquid, work as gas pressure
When increase, the Simultaneous Pressure of gas-liquid mixed layer increases in liquid chamber, and wheel rotation resistance is increase accordingly, and output power of motor is same
Step increases.Outlet pressure is gradually increasing by zero, and motor power consumption is changed by zero to rated output power is synchronous, wheel speed adjusting,
The adjusting etc. of outlet load is realized by controller.
The present invention, as relaying compressed media, has achieved the purpose that improve out wind pressure using liquid.
The liquid level of air compressor machine setting of the present invention is shown and pressure shows that sensor can reserve automatically-monitored connect
Mouthful, to connect controller, liquid level and pressure and other parameters are carried out automatically-monitored.
Centrifugal fan impeller 4 of the present invention can have a variety of structures, and be not limited to the present embodiment the structure enumerated.
