Pump vacuum water ring BBH 1-1,5
The pump VVN - vacuum, water ring with omental consolidation of a shaft. The pump consists of the following main details: covers, cases, disk, arm, shaft. At rotation of a disk the water which is carried away by shovels under the influence of centrifugal forces, is rejected to a cover perefiriya, forming a water ring. Between a nave of a working disk and an internal surface of a water ring the rarefied space providing absorption of gas through big crescent cut in a pump housing is created. At further rotation of a disk there is a compression of the pumped-over gas. Through small crescent cut in the case gas and excessive water is thrown out a delivery branch pipe of the pump.The pumped-over liquid:
The pump vacuum the BBH1-1,5 type and the unit electric pump on its basis, intended for creation of vacuum at an outside work or inert gases insoluble in water.Symbols of the electric pump unit:
