Marine pump function and classification

Marine pump is a liquid fluid energy machinery. Not only to transport liquid pump, more important is the displacement and pressure to meet work requirements. Since transferring tasks vary, therefore, according to the working principle of distinction, reciprocating pumps, rotary pumps,centrifugal pumps,windlass and jet pumps and other four. Liquid always flows downhill, to make it flow uphill, it must be liquid acting to get some energy, a pressure forcing the liquid to go uphill. A mechanical pump is a certain energy to the liquid, which is a source of energy by the prime mover. Fluid pumps can transport liquids, mainly because it constantly absorbing liquid discharge liquid. The liquid is sucked by the pump pressure is both a vacuum pump and the pump outer atmospheric pressure difference. The higher the vacuum, the more the pressure, the stronger the pump suction. There is no vacuum, pressure is zero, the pump can not suck the liquid.

By Application: transport diesel engine, the required boiler fuel, lubricating oil, power oil, cooling water, makeup water; daily delivery of fresh water needed for the crew and passengers of life, health and water; safe navigation of ships needed to transport ballast water, fire water, bilge water.
