Abstract

The invention provides a marine electric pump system assembly and a working method thereof and belongs to the field of liquid pumping equipment. The marine electric pump system assembly comprises a pipeline pump suction inlet pipeline and a sliding vane pump suction inlet pipeline; a branch is arranged at the lower part of the pipeline pump suction inlet pipeline; an electric immersed pump is arranged on the branch; a bottom valve is arranged at the lower end of the pipeline pump suction inlet pipeline; the bottom valve and the electric immersed pump are arranged corresponding to the bottom ofa liquid tank in a ship; the bottom valve is a one-way valve only opened towards the interior of the pipeline pump suction inlet pipeline; the upper part of the electric immersed pump communicates with the input end of an anti-explosion pipeline pump; the output end of the anti-explosion pipeline pump communicates with an oil collecting pipeline; the upper end of the sliding vane pump suction inlet pipeline stretches out of a ship deck and communicates with the input end of a vacuum sliding vane pump; and the output end of the vacuum sliding vane pump communicates with the oil collecting pipeline. The marine electric pump system assembly conveys liquid in the suction pipeline of the anti-explosion pipeline pump through positive pressure, thoroughly solves the air resistance problem generated when liquid is conveyed through negative pressure, and is low in cost and high in power.

Description

technical field [0001] The invention belongs to the field of liquid pumping equipment, and relates to a system assembly of an electric pump for transporting liquid, in particular to a system assembly of a marine electric pump and a working method thereof. Background technique [0002] At present, two types of electric pumps are usually used for the transportation of marine liquids. The first type of electric pump uses an explosion-proof pipeline pump to unload the liquid in the ship. The negative pressure generated after the operation of the pipeline pump sucks the liquid into the explosion-proof pipeline pump. After the pipeline pump is pressurized, it is transported to the storage device on the port. The advantages of using the above-mentioned marine explosion-proof pipeline pump to transport liquid are low cost and easy maintenance. Easy, its main defect is that the suction of the marine explosion-proof pipeline pump is very small, and it cannot be installed directly on t...
