INSTALLATION FOR RESEARCH cavitation characteristics of centrifugal pumps

摘要

The purpose of the utility model is to determine the dependence of the pressure of the centrifugal pump by the liquid pressure at the pump inlet.; Apparatus for studying the cavitation characteristics of the centrifugal pump comprising a centrifugal pump 1, the tank 2, a filter 3, a pressure conduit 4, suction pipe 5, the flow valve 6, a pressure gauge 7 included in the suction pipe 5 to the discharge conduit 4 are connected in series a second pressure gauge 8, flow rate valve 6, the vortex flow meter 9, the pressure line 4 is connected to the lower part of a tank 2, the air reservoir chamber 2 is connected to a vacuum manifold 10 which is connected to a vacuum pump 11, and between the reservoir and the vacuum pump set vacuum valve 12. If the output than the centrifugal pump 1 is connected by means of the flow conduit, flow rate through valve 6, the vortex flowmeter 9 with tank 2, and the input of the centrifugal pump 1 is connected to a filter 3 through the suction pipe 5 which is connected to a pressure gauge 7. gauge 8 connected to the discharge conduit 4 and mounted between the centrifugal pump 1 and the flow valve 6.
