METHOD OF GAS REMOVAL FROM LIQUID SYSTEM Russian patent published in 2002 - IPC

FIELD: removal of gases from working main lines of complicated hydraulic drives and various liquid (fuel, oil, etc) systems; applicable in mechanical engineering, aviation, transport, etc. SUBSTANCE: method includes pumping through main lines of working fluid with drainage through drainage unit of liquid system and identification of undissolved gas in system. Pumping through is effected in pulse regime with frequency from 0 to 100 Hz and excessive average pressure of at least 0.1 MPa in system. Working fluid is used in the form of degassed fluid. As gas removal fluid proceeds, pulse frequency is increased. With noticeable retardation of process, coefficient of pulse filling is changed to allow displacement of zone of maximum pulsation amplitude to highly throttled channels of liquid system with gas plugs. In the course of gas removal provision is made for continuous repeated use of drained working fluid, and also quantitative identification of gas in system. EFFECT: higher efficiency. 6 cl
