DEVICE FOR DAMPENING PRESSURE FLUCTUATIONS IN LIQUID FLOW Russian patent published in 1994 - IPC

FIELD: mechanical engineering. SUBSTANCE: device for dampening pressure fluctuations in liquid flow has disperser 7, gas bottle, control valves and branch pipes 3 and 2 for supply and discharge of liquid, respectively. Device has housing 1 made in form of tight reservoir, diffuser 4, guide vanes 5, baffle plate 6, level sensor 15, compressor and low-noise throttle valve. Liquid supply and discharge branch pipes are connected with lower portion of housing; liquid supply branch pipe being connected with housing through diffuser 4. Guide vanes 5 are located in housing on side of outlet of diffuser 4. Disperser 7 is mounted in lower portion of housing between branch pipes 3 and 2 after guide vanes 5; baffle plate 6 is mounted in top portion of housing and is located above guide vanes and disperser. Level sensor is secured to lower portion of housing and disperser 7 is secured on outer side of housing and is connected with pressure side of the compressor and with gas bottle 13 via control valves 12, as well as with low-noise throttle valve which is brought in communication with atmosphere. Upper portion of housing is brought in communication with suction chamber of compressor. EFFECT: enhanced efficiency. 2 dwg
