PROCESS OF OPERATION OF PUMP AND EJECTOR PLANT AND PLANT FOR ITS IMPLEMENTATION Russian patent published in 1999 - IPC

FIELD: creation of vacuum. SUBSTANCE: plant is fitted with hydrodynamic device adjusting velocity of flow produced in the form of one or several conduits expanding along motion of gas and liquid flow. Inlet of device is connected to outlet of gas and liquid flow from ejector and to separator on side of exit of flow from device. Area of outlet section of each conduit expanding along flow amounts to 4.0 to 50.0 areas of inlet section of this conduit and length of each expanding conduit is not less than , where S is area of outlet section of expanding conduit. Gas and liquid flow from ejector is fed into hydrodynamic device where this flow is decelerated by setting velocity of motion of gas and liquid mixture below velocity of sound. After this gas and liquid flow is fed with subsonic velocity into separator where compressed gas is separated from liquid working medium. EFFECT: enhanced functional reliability of plant. 4 cl, 2 dwg
