A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical action. Pumps are vitally important for the ship operation. If they fail, the power plant they serve, can also fail. Pumps failures can prove disastrous in case of any emergency on board.
The most common types of pumps are the displacement pumps and the dynamic pumps.
Displacement pumps: 1.Gearwheel pump 2.Reciprocating pump 3.Screw pump 4.Vane pump.
Dynamic pumps: 1.Centrifugal pump 2.Axial flow pump 3.Centrifugal-axial (mixed) pump. 4.Jet pumps.
Pumps on ships are used for the following main purposes:.
These pumps are used in engine cooling systems and in a seawater lines.
These pumps are used in ballast systems.
It is used for pumping large quantities of water overboard . Educators make an important part of drainage system and damage control systems.
Vane pumps are used for liquid transfer applications from chemicals to liquefied gases. Vanes extend from slots in the rotor, sweeping liquid through a cam-shaped cavity.
