A vessel operated on must be fitted with various equipment. The use of these equipment to complete the ship's voyage, berthing, loading and unloading cargo production operations, and to ensure the safety of ships and personnel. The main equipment of ships is powered equipment, manipulation equipment, handling equipment and safety equipment.
Marine Power Equipment
Ships must be equipped with a set Marine Accessories of power plants and auxiliary equipment that meet the requirements of the specification before they can sail Marine Accessories on water. These power plants include the main power plant, auxiliary power plant, steam boiler, refrigeration and air-conditioning unit, compressed air device, marine pump and piping system, water-making device and automation system. This electromechanical equipment is mainly concentrated in the cabin, specializing in the management of these equipment the technical department is the Department of Marine Engineering.
1, main power plant
The ship's main power plant is also known as "host", it is the heart of ships, the most important part of the ship powertrain,
2, auxiliary power plant
The Marine auxiliary power Unit is also Marine Accessories called "Auxiliary Machine", which refers to the generator on the ship, which provides electricity for the ship in the normal condition and emergency situation. By the engine group, power distribution plate and other electromechanical equipment constitute the ship power station.
3, Steam Boiler
The diesel engine is the host of the vessel, Marine Accessories it is necessary to have a steam boiler, it is composed of auxiliary fuel furnace and exhaust gas boiler, as well as the supporting services of the pipe system and equipment. Auxiliary fuel boiler is the need for the supply of auxiliary steam, such as heating oil and lubricating oil, heating, living water, kitchen, boiling water, and satisfying Marine Accessories the need of steam for some auxiliary machines. For energy saving, the exhaust gas boiler uses the waste heat from the exhaust of diesel engine to generate steam, and only the auxiliary fuel boiler is used in the mooring.
4, refrigeration and air-conditioning devices
The installation of refrigeration equipment for ships Marine Accessories is refrigerated transport cargo, refrigerated a certain amount of food, and improving the living conditions of the crew and passengers. The task of an air conditioner is to keep the cabin in a climate condition suitable for Marine Accessories people's work and life, including summer cooling, dehumidification, heating in winter, humidification and ventilation throughout the year. Its main equipment has refrigeration compressor, evaporator, condenser, air-conditioner and its automation control components.
5, compressed air device
The general ship is equipped with multiple air Marine Marine Accessories Accessories compressors and a plurality of compressed air bottles to supply all the necessary compressed air, such as the use of compressed air to start the main, auxiliary diesel engine; Its main equipment has air compressor, gas storage bottle, pipe system and safety, control components.
6. Marine Pumps and piping systems
In order to pump sea water, fresh water, fuel, lubricants and other liquids, need a certain number and different types of pumps. Generally in the cabin must be set up bilge pumps, fuel and lubricating oil pump, boiler feed pumps, cooling water pumps, ballast pumps, sanitary pumps and other major pumps and pumps. Connected with the pump, the ship set up a variety of uses of pipelines.
7. Water-making device
The water-making device, also known as the water-making machine, is the equipment that heats the seawater in a vacuum and condenses the steam into fresh water.
8. Automation system
With the progress of science and technology and the extensive application in ship, the engine room control system is more and more advanced, the long-distance manipulation and centralized control of the marine power plant, greatly improves the working conditions of the crew, improves the work efficiency and reduces the maintenance and repair workload. The automatic system of remote control, automatic adjusting, monitoring and alarming of the main, auxiliary and other mechanical equipments of the cabin is an indispensable part of modern ships.
