Description

Technical Field

[0001] The utility model relates to the technical field of ship drainage devices, in particular to a tank stripping operation pump used in a ship drainage system. Background Art

[0002] A stripping pump in a ship's drainage system is typically used to remove water from tanks or holds during the ship's drainage process. It is a pump specifically designed to quickly and efficiently remove accumulated water from the hold and transport it to the sea surface or other drain outlets.

[0003] During tank stripping and drainage, the pump body transports water through the rotation of the cam. However, since the water in the ship's cabin contains a large amount of impurities and particles of varying sizes when the pump body transports water, small particles have little impact on the cam during transportation. Once large particles are transported through the cam, the cam will cause greater friction and damage, affecting the service life of the overall tank stripping operation pump.

[0004] Therefore, it is necessary to design a tank stripping pump for a ship drainage system to solve the above problems. Utility Model Content
