Description
Technical Field
The invention relates to the technical field of ships, in particular to a passenger ship volumetric pump flow control system and method and a passenger ship.
Background
According to the requirements of the regulations, the ship built 1 month 1 year 2009 or later should be provided with an effective bilge water pumping system, which can pump and drain water of any watertight compartment under all practical conditions, except for the places fixed for loading fresh water, ballast water, fuel oil or liquid cargo and provided with other effective drainage devices. The passenger ship can operate under all practical conditions after the sea loss no matter the ship floats forward or leans transversely.
The passenger ship is required to be provided with at least three power pumps and is connected with a bilge main pipe, the bilge main pipe is communicated with a stern to a bow, a through suction port pipeline or a branch suction port pipeline is arranged on the main pipe to all watertight cabins, for example, water is fed into a certain cabin, the water feeding cabin is judged through a liquid level switch signal, a remote control valve of the cabin is opened, and the power pump is utilized to pump out, so that water in the cabin is timely discharged, and the residual capacity of the ship is ensured.
Since 120m and above, or passenger ships having three or more main risers should meet the requirements for safe harbor, the bilge water system of other cabins or main risers should remain effective when any cabin or main riser is not in use due to fire. Thus, several bilge pumps of the passenger ship need to be arranged in regions, and bilge pumps close to the bow and stern may be located at a higher position from the base line due to the design of the hull structure, and may be more than 5 meters.
For example, centrifugal pumps of conventional configuration, the self-priming capacity is typically 4-5 meters, and arrangements above 5 meters cannot be met. The arrangement of more than 5 meters generally adopts a volumetric pump, but the volumetric pump is characterized by constant displacement, and the pipe diameter is determined according to calculation when a certain cabin is pumped point to point, so that no problem exists. However, for bilge systems, the design is very complex, bilge pump displacement is determined according to the pipe diameters of the through suction port and the bilge main pipe, but when bilge water branch pipes in empty cabins are pumped, the pipe diameters of the branch suction ports are far smaller than those of the main pipe, and the pump displacement is not matched with the pipe diameters of the branch suction ports, so that cavitation is easy to occur.
Accordingly, there is a need for a passenger ship volumetric pump flow control method that addresses the above-described issues.
