Ships must be equipped with a complete set of power plants and auxiliary equipment that meet the requirements of the regulations before they can sail on the water. These power plants include ship main power plants, auxiliary power plants, steam boilers, refrigeration and air-conditioning plants, compressed air plants, marine pumps and piping systems, water generation plants and automation systems. This electromechanical power equipment is mainly concentrated in the engine room, and the technical department that specializes in managing these equipment is the engineering department.
1. The main power unit
The main power plant of a ship is also called the "main engine". It is the heart of the ship and the most important part of the ship's power equipment. It mainly includes:
(1) Ship main engine
A common name for engines that can generate propulsion power for ships, including various pumps, heat exchangers, and piping systems that serve the main engine. At present, the main engine of merchant ships is mainly marine diesel engines, followed by steam turbines.
(2) Transmission device
The equipment that transmits the power of the main engine to the propeller can not only transmit power, but also play a role in deceleration and shock absorption. The boat can also use transmission equipment to change the direction of rotation of the propeller. The transmission equipment is slightly different due to the different types of the main engine. Generally speaking, it is composed of a reducer, a clutch, a coupling, a coupling, a thrust bearing and a ship shaft.
(3) Shafting and thruster
Among ship propellers, propellers are the most widely used, and most of them use fixed pitch or adjustable pitch propellers; the ship shafting is a device that transmits the power from the main engine to the propeller. The main engine of the ship drives the propeller to rotate through the transmission device and the shaft system to generate thrust, which overcomes the resistance of the hull to make the ship move forward or backward.
2. Auxiliary power unit
Ship auxiliary power unit, also known as "auxiliary engine", refers to the generator on board, which provides electrical energy for the ship in normal and emergency situations. The marine power station is composed of electromechanical equipment such as engine block and switchboard.
(1) Generator set
The driving force is mainly provided by diesel engines. Based on the consideration of ship safety and reliability and easy maintenance and management, large ships are equipped with no less than two diesel generators of the same model, which can generate electricity at the same time as required.
In order to save energy, some ships can use the drive shaft of the main engine to drive the generator to generate electricity (shaft generator) or use the waste heat of the main exhaust gas to generate low-pressure steam to drive the turbine generator set to generate electricity.
(2) Switchboard
It carries out the distribution, control, transmission, voltage transformation, and current conversion of electricity to ensure the needs of various electric driving equipment and the life, lighting, signal and communication of the whole ship.
