船舶管路的含义及组成（The meaning and composition of vessel line） The meaning and composition of ship piping system In the power device of ship, ship piping system refers to the special use and the conveying fluid (liquid or gas) of the auxiliary machinery (such as pump, fan, compressor, oil separator, etc.) equipment (such as heat exchangers, cabinet, filter, air bottle etc.), instrumentation and pipeline (pipe and accessories in general, referred to as pipe). The ship piping system according to use is divided into two categories: for piping service propulsion device known as the power system in order to guarantee normal operation of the propulsion device; pipe system to service the whole ship called the ship control system, to ensure the vitality of ship navigation safety, and the crew and passengers of the normal life and work. Dynamic piping according to their different tasks, the system consists of the following five aspects: (1) the fuel pipe system; (2) oil pipe line; (3) cooling pipe system; (4) the compressed air pipe system; (5) into the exhaust pipe. Ship piping system according to the different tasks, the system consists of: (1) bilge system; (2) the ballast water system; (3) fire control system; (4) ventilation pipe system; (5) the water supply pipe system; (6) injection, measurement, ventilation pipe system; (7) steam pipe system; (8) drainage pipes. In addition, according to the different types of ships also set hydraulic piping, piping water immersion, in some special ships such as oil tankers, chemical tankers, liquefied gas tankers, also set up some special system. Common are: liquid cargo handling system, washing system, inert gas protection system and cargo heating system etc.. In the dynamic pipe system, the engine itself has some of the machinery, equipment part, in the design of diesel engines has been solved, known as the internal power system, the remaining part is called the external power system (solved in designing the power plant).
