Experimental principle of the invention is as follows:
High-pressure vortex air pump delivers gases into gas-liquid mixed tank, the mist generated with gas-liquid mixed tank tank bottom ultrasonic atomizer
Change droplets mixing, form gas-liquid mixed vapour, provides unstripped gas for performance test experiment.
Gas-liquid mixed vapour property is controlled by following manner:
(1) gas-liquid mixed steam flow amount by high-pressure vortex air pump flow control.Made by the first ball valve, the first gate valve joint
With, using bypass regulative mode high-pressure vortex air pump flow is controlled, by adjusting the first ball valve aperture coarse adjustment high pressure rotation
Whirlpool air pump flow, by adjusting the first gate valve aperture fine tuning high-pressure vortex air pump flow.The flow of high-pressure vortex air pump is by first
Spinner flowmeter measurement.First temperature sensor, first pressure sensor are set before the first rotor flowmeter, measure gas temperature
And pressure, the amendment for the first rotor flowmeter flow rate test value.
