< h3>How many types of generators are there?There are two cooling methods for diesel generator sets: air cooling and water cooling.
1. Wind Cooling Method:
The wind cooling method uses air as a cooling medium to transfer heat from the heated parts of the diesel engine. This method of refhardening consists of cooling. fan and guide cover, etc.
In order to increase heat dissipation neps, many corrugated fins are usually cast on the outer walls of the cylinder block, cylinder head and each radiator. During operation, the fan rotates to circulate air along the air guide cover to the surface of the cylinder block and cylinder head. As cold air passes through the heat sink, it carries away heat from the cylinder block and cylinder head.
The air-cooled cooling system has a simple structure and small weight, but the cooling effect is poor. It is mainly used in small diesel engines and is suitable for areas lacking water.
2. Water Cooling Method:
Water cooling method uses water as a cooling medium to transfer heat from heated partsof the diesel engine. The characteristic of this cooling method is that it is easy to adjust the cooling intensity when the temperature or workload changes.
There are two types of water cooling methods: open type and closed type. In an open cooling system, the circulating water is directly connected to the atmosphere and the steam pressure in the cooling system is always maintained at atmospheric pressure. In a closed system, water circulates in the closed system and the vapor pressure of the cooling system is greater than atmospheric pressure. As the temperature difference between the cooling water temperature and the outside air temperature increases, the heat dissipation capacity of the assembly increases. the cooling system is improved.
The classification of generators includes:
Generators are divided into:direct current generators and alternators; AC generators are divided into: synchronous generators and asynchronous generators (rarely adopted); can also be divided into single-phase generator and three-phase generator.
There are many types of generators. In principle, they are divided into synchronous generators, asynchronous generators, single-phase generators and three-phase generators.
In terms of production methods, they are divided into steam turbine generators, hydraulic generators, diesel generators, gasoline generators, etc. In terms of energy, it is divided into thermal generators, hydraulic generators, etc.

Generator specifications:
1 Operating characteristics:
The performance of synchronous generators is mainly characterized by the no-load characteristics and the characteristicsticks of operation under load. These features provide an important basis for users to choose generators.
2. No Load Characteristics:
When the generator is not connected to a load, the armature current is zero, which is called Run No Load. At this time, the three-phase winding of the motor stator only has the no-load electromotive force E0 (three-phase symmetry) induced by the excitation current If, and its size increases with the increase of If. However, due to the saturation phenomenon in the core of the motor magnetic circuit, the two are not proportional. The curve reflecting the relationship between the no-load electromotive force E0 and the excitation current If is called the no-load characteristic of the synchronous generator.
3. Armature reaction:
When the generator is connected to a symmetrical load, the three-phase current in the armature winding will produce another rotating magnetic fieldt, called induced. reaction magnetic field. Its speed is exactly equal to the speed of the rotor and the two rotate synchronously.
The armature reaction magnetic field and the excitation magnetic field of the synchronous generator rotor can be approximately considered to be distributed according to the sinusoidal law. The spatial phase difference between them depends on the temporal phase difference between the no-load electromotive force E0 and the armature current I. The armature reaction magnetic field is also related to the charge state.
When the generator load is inductive, the armature reaction magnetic field acts as a demagnetizer, which will cause the generator voltage to decrease; when the load is capacitive, the armature reaction magnetic field acts as a demagnetizer; a magnetizer. This will increase the output voltage of the generator.
