Before the ship sails, it must be equipped with a set of power plants and auxiliary equipment that meet the requirements of the code. This type of electrical equipment includes the main electrical equipment of the ship. Auxiliary electrical installations. Steam boilers. Refrigeration and air conditioning equipment. Compressed air installations - Marine pumps and piping systems. Water production equipment and automation systems. This mechanical and electrical equipment is mainly concentrated in the engine room, and the engine department is the engine department.
1. Main power equipment.
Marine power supply is also called the "main engine", which is the heart of the ship and the Z component of the ship's power equipment, mainly including:
(1) Ship main engine.
An engine used to generate Marine propulsion power, including various pumps and heat exchangers, piping systems, etc. At present, the commercial ship is mainly powered by Marine diesel engine, followed by steam turbine.
(2) Driving device.
The power of the main engine is transmitted to the propulsion device, which can not only transmit power, but also play the role of deceleration and shock absorption. The driving device can also be used to change the rotation direction of the propeller. The driving device is slightly different depending on the type of host, and in general is by the reducer. Clutch. Coupling. Couplings. Thrust bearings and shafts, etc.
(3) shafting and thrusters.
In ship propulsion, Z is widely used in propellers, which are usually fixed pitch or adjustable pitch propellers. The shaft is a device that transmits the power from the main engine to the propeller. The ship owner is through the transmission and shafting drive propeller rotation to produce thrust, to overcome the hull resistance to make the ship forward or backward.
