What is A Diesel Generator Set?

Today we will give you a brief introduction about what is a diesel generator set.

Diesel generator set is a type of AC power supply equipment in self-supplied power station. It is a small independent power generation equipment that uses an internal combustion engine as power to drive a synchronous alternator to generate electricity. Modern diesel generator sets are composed of diesel engines, three-phase AC brushless synchronous generators, control boxes (screens), cooling water tanks, couplings, fuel tanks, mufflers and public bases and other components to form a rigid whole. The flywheel housing of the diesel engine and the front end cover of the generator are directly connected in the axial direction by a shoulder positioning to form a whole body, and a cylindrical elastic coupling is used to directly drive the rotation of the generator by the flywheel. The connection method is fixed by screws to make the two They are connected into a steel body to ensure that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within the specified range.

The diesel generator set is composed of an internal combustion engine and a synchronous generator. The rated power of the internal combustion engine is limited by the mechanical load and thermal load of the parts and is called the rated power. The rated power of the AC synchronous generator refers to the rated speed, During long-term continuous operation, the rated power output is usually called the matching ratio between the rated power output of the diesel engine and the rated power output of the synchronous alternator.

Overview: Diesel generator set is a kind of small power generation equipment, which refers to power machinery that uses diesel fuel as fuel and diesel engine as prime mover to drive generator to generate electricity. Diesel generator sets are generally composed of diesel engines, generators, control boxes, fuel tanks, storage batteries for starting and control, protection devices, emergency cabinets and other components. The whole can be fixed on the foundation and used for positioning, or it can be installed on a trailer for mobile use. Diesel generator sets are non-continuous operation power generation equipment. If they operate continuously for more than 12 hours, their output power will be about 90% lower than the rated power.

Although diesel generator sets have low power, they are widely used in mines, railways, field construction sites, road traffic maintenance, factories, enterprises, hospitals and other departments due to their small size, flexibility, light weight, complete supporting facilities, and easy operation and maintenance. , As a backup power supply or temporary power supply. In recent years, the newly developed unattended fully automatic emergency power station has further expanded the scope of use of this type of generator set. At present, my country has more than 10 production plants with export production capacity, including Tianjin Power Generation Equipment Factory. The products are exported to dozens of countries and regions in Europe, Asia and Africa, and are well received.

Classification and specifications: Diesel generator sets are classified according to the output power of the generators. The energy of the generator sets varies from 10kW to 750kW. Each specification is divided into protection type (equipped with over-speed, high water temperature, low oil pressure protection device), emergency type and mobile power station type. Among them, the mobile power station is divided into high-speed off-road type whose speed can be matched with the speed of automobile and ordinary mobile type with low speed.

Precautions for ordering: The export inspection of diesel generator sets is carried out in accordance with the relevant technical or economic indicators of the contract or the technical agreement. The user should pay attention to the following points when selecting and signing the contract: If the environmental conditions are used in accordance with the calibration environment of the diesel generator set When there is a gap in the condition value, the temperature, humidity and altitude value should be stated at the time of signing the contract to provide suitable models and supporting equipment; explain the cooling method adopted during use, especially the large-capacity unit, and pay more attention; when ordering, In addition to the unit model, it is also necessary to specify which model to choose; the voltage adjustment rate of the diesel unit is 1%, 2%, and 2.5% of the rated voltage. Which one to choose should also be explained; in normal supply, a certain amount of wearing parts should be provided, and if there are other needs, it should also be explained.

Inspection items and methods: Diesel generator sets are a complete set of products, including diesel engines, generators, control components, protection devices, etc. The whole machine inspection of export products includes the following contents: product technology and inspection data review; product specifications, models, main structural dimensions; product overall appearance quality; unit performance: main technical parameters, unit operation adaptability, and The reliability and sensitivity of this automatic protection device; other items specified in the contract or technical agreement.
