Description
Marine diesel generators are an important piece of equipment used in Australian ships and marine installations. They burn diesel to generate electricity for the power and electricity needs of the ship. Marine diesel generators are widely used in the Australian marine industry due to their high efficiency, reliability, and durability.
Marine diesel generator sets generally include common marine diesel generator sets and emergency marine diesel generators. The marine generator set uses open circulating water to cool the diesel engine. Because the working environment of the marine generator set is relatively harsh, the marine diesel generator set is generally placed on the deck of the cabin and has high installation requirements for water supply and drainage, air supply, and smoke exhaust. The manufacturing process of marine generator sets is complicated, and the relative production cost is much higher than that of land-use diesel generators.
Marine Diesel Generator Working Principle
The marine diesel generator working principle is to convert the heat energy generated by diesel combustion into mechanical energy, and then convert the mechanical energy into electrical energy through the generator. This kind of generator usually consists of two parts: a diesel engine and a generator. The diesel engine is responsible for burning diesel oil, producing high-temperature and high-pressure gas, and then converting the gas into mechanical energy through the movement of the piston. The generator converts mechanical energy into electrical energy and outputs it to the ship’s electrical system.
Marine Generator Australia Function
There should be at least two main units (commonly used marine diesel generators and emergency marine diesel generators), and it is best to use the same type of generators for ease of maintenance and management;
The unit is to be capable of supplying the electric power necessary to start the main propulsion plant from a dead ship state when any generator or its prime mover is not in operation;
Under the condition of continuous operation, it is hoped that the rated output power of the diesel engine has a margin of about 10%; however, the diesel engine should not be obviously operated at a low load state;
The capacity and number of units shall be such that when any unit stops working, it shall still be able to continue to supply power to the equipment necessary for normal propulsion operation, ship safety, and refrigerated cargo of ships with refrigeration class;
When one unit stops working, the remaining units should have sufficient reserve capacity to ensure that the transient voltage drop generated when the largest motor starts will not cause any motor stall or other electrical equipment to fail;
The unit is most efficient when it is operated near the rated value without exceeding the rated value. Under normal operating conditions, the power necessary for sailing conditions shall be taken as the benchmark, the unit shall not be overloaded for load changes and increases, and the rated capacity of the unit shall have an appropriate reserve;
Marine Diesel Generator Advantages
First, they are highly efficient, keeping the ratio of energy converted from fuel to electricity at a high level. This enables the ship to obtain more power output with less fuel consumption, improving fuel utilization.
Secondly, marine diesel generators have the characteristics of high reliability. They have been strictly tested and inspected and can operate stably for a long time in harsh marine environments.
In addition, marine diesel generators have a long life and can withstand long-term operation and high-load use.
In the Australian marine industry, marine diesel generators are widely used in various ships and marine facilities. They provide power and electricity to the Australian ship, enabling the ship to sail smoothly and perform various operations. At the same time, marine diesel generators are also used in Australian marine facilities such as offshore oil platforms, fishing boats, and passenger ships to provide reliable power support for these facilities.
In conclusion, a marine diesel generator in Australia is an efficient, reliable, and durable device that provides vital power support for Australian ships and marine installations. Their wide application has promoted the development of the Australian marine industry and provided a reliable source of energy for offshore activities.
