Ship's tank pumping equipment - has float switches controlling exhauster in pipe between vacuum tanks

摘要

The pumping equipment for ship's tanks comprises a loading pump and blowing equipment consisting of a separator tank in the suction pipe. A vacuum tank has an exhauster connected to the top of this tank, with an automatic control switch for the exhauster. A bypass pipe is of cross-section adjustable dependent on the level of liq. in the separator tank, to limit the quantity delivered by the loading pump. The switchgear controlling the exhauster comprises an auxiliary suction pipe from the vacuum tank to an auxiliary vacuum tank at a lower level. Float switches in the auxiliary pipe are one above the other.
