Cargo pump apparatus for liquid cargo ship

摘要

A cargo pump apparatus is suitable for liquid cargo ships required to carry six to eight types of cargo and having a plurality of holds partitioned by a central bulkhead standing upright on a lower longitudinal stool and transverse bulkheads. Each cargo pump room is provided at an intersecting portion of the central bulkhead and one of the transverse bulkheads, and penetrates a hatch provided on an upper deck and the lower longitudinal stool. One deep well pump is provided in each cargo pump room. The suction side of the deep well pump is connected to a cargo suction portion which has an open end in the hold and penetrates the inclined wall of the lower longitudinal stool. The discharge side of the deep well pump is connected to a cargo discharge pipe connected to a manifold pipe laid on the upper deck through the cargo pump room. Either the cargo suction portion in the cargo pump room is connected through an expansion pipe, or the deep well pump is secured through an expansion pipe.
