The first group – pumps, hydraulic drives and fans, the second – deck machinery. The first group provides the effect of different purpose of ship systems, including the main power plants. The second group is steering gears, anchor-mooring and lifting devices. Perhaps check out Road tankers for more information. Ship lifting devices are divided into the cargo winches and cranes. Their purpose – to ensure that cargo operations at loading and unloading of marine transport vessels for general purposes. Cranes are more comfortable and productive in the processing of general cargoes, winches can also raise the heavyweights in the presence of heavy arrows and the corresponding rigging. A special group are towing winches, providing flexible communication with the ship towed.
Marine equipment are steam, electric, hydraulic and manual drives. CLASSIFICATION OF PUMPS FOR destination by purpose pumps are distinguished: 1) the bilge of the vessel systems, and 2) ensure the operation of the power plant, and 3) emergency rescue systems, and 4) ensuring the sanitary needs of the crew and passengers, and 5) commercial systems oil tankers, 6) special ship systems. The first group includes the bilge bilge and ballast pumps. In the engine and boiler room (ICE), marine vessels have leaks in pipe joints and valves, which creates a diversion of water, fuel and oil, condensate and liquid loss by blowing and washing arrangements and systems. Infiltration of moisture and possibly into the cargo hold of a ship from joints of pipelines passing through the holds .. Of drainage wells cargo holds water periodically removed bilge bilge pumps, which in this case, switch to the corresponding system of the ship.
