Description

Technical Field

[0001] The utility model relates to the technical field of ballast water pumps, in particular to a ship ballast water control device. Background Art

[0002] The ship's ballast water system is mainly composed of ballast water pumps, ballast water pipelines, ballast tanks and related valves. The function of the system is: to inject or discharge the ballast tanks of the entire ship according to the needs of ship operation, so as to adjust the ship's draft and the longitudinal and lateral stability and safe metacentric height of the hull; to reduce hull deformation to avoid causing excessive bending moment and shear force, reduce hull vibration, and improve the seaworthiness of empty tanks. The ship's ballast water treatment system is a device for treating the ballast water discharged into the sea by the ship. The ship's ballast water system should be able to transfer the ballast water of all ballast tanks on the whole ship, transfer it out or transfer it to each other. It also does not require a ballast pump, and the outboard seawater automatically flows into the ballast water tank by pressure difference.

[0003] The prior art patent document with publication number CN214196696U provides a ballast water pump for a ballast water system. The new self-heating device can utilize the water pumped by the ballast water pump to dissipate the heat of the water pump motor. This method not only does not use additional external energy, but also can achieve heat dissipation operation for the working water pump motor, thereby ensuring that the water pump motor that provides power to the pump body can always operate at a safe temperature, thereby increasing the stability and service life of the ballast water pump for the entire ballast water system. However, when the patent CN211876566U is in use, although it can utilize the water pumped by the ballast water pump to dissipate the heat of the water pump motor, the water is quickly transported in the U-shaped sleeve, and the excessive speed makes the contact time with the motor short, resulting in poor heat dissipation effect. Therefore, a ship ballast water control device is urgently needed. Utility Model Content
