FIELD: engines and pumps. ^ SUBSTANCE: proposed self-suction water pumping plant consists of suction pipeline, centrifugal pump, filler neck, pressure pipeline with shut-off valve and ejector. It comprises also a vacuum cylinder with filler neck fitted in its cover. Note that the drain pipe one end is connected to the vacuum cylinder upper cover, the other end of the said pipe is introduced into the ejector arranged between the vacuum cylinder and centrifugal pump. Note also that the plant features leaking properties allowing raising water up from the source with rarefied suction pipeline and draining it out with the centrifugal pump stopped. ^ EFFECT: higher reliability. ^ 1 dwg |
