How much do you know about generator sets?


厂家来跟大家说说发电机组的小常识,带上小板凳一同来看看吧! Guangzhou generator repair factory to talk to you about the common sense of generator sets, take a small bench and take a look! !! !!
In general, our common generator sets are generally driven by steam turbines, water turbines or internal combustion engines (gasoline engines, diesel engines and other engines), and in recent years the renewable new energy sources include nuclear energy, wind energy, solar energy, biomass energy, ocean energy, etc.
Because the diesel generator set has a large capacity, it can work in parallel and continue to supply power for a long time. It can also work independently. It does not work side by side with the regional power grid, and is not affected by grid faults. It has high reliability.
Especially in the case that the common commercial power in some areas is not very reliable, the diesel generator set can be used as a backup power source, which can not only play the role of emergency power supply, but also rationally optimize the low-voltage system and put some of the more important loads in the power outage Time, so it is widely used in engineering. The basic principles and structural methods of common generator sets are introduced below.
Diesel-driven generators work to convert diesel energy into electricity. According to their uses, they can be divided into land-based diesel generators and marine diesel generators. If they are based on different brands, they can be divided into domestic diesel generators and imported diesel generators. Generator set; according to different speed, it can be divided into low-speed generator set and high-speed generator set.

A diesel engine drives a generator to convert the energy of diesel into electricity. In the diesel engine cylinder, the clean air filtered by the air filter is fully mixed with the high-pressure atomized diesel injected by the fuel injection nozzle. Under the upward compression of the piston, the volume is reduced, and the temperature rises rapidly, reaching the ignition point of the diesel. The diesel was lit, and the mixed gas was incinerated violently, the volume swelled rapidly, and the piston was pushed downward, which is called 'work'.

The cylinders work in sequence in a certain order, and the thrust on the piston passes through the connecting rod and becomes the force to propel the crankshaft to roll, which then drives the crankshaft to rotate. By installing the brushless synchronous alternator coaxially with the crankshaft of the diesel engine, the rotor of the generator can be driven by the rotation of the diesel engine. Using the principle of "electromagnetic induction", the generator will output the induced electromotive force and the current will be generated through the closed load circuit. . Only the most basic working principle of the generator set is described here. To obtain a usable and stable power output, a series of diesel and generator control and maintenance components and circuits are also required.
An ordinary diesel generator set is mainly composed of a diesel engine, a generator and a control system. There are two connection methods for a diesel engine and a generator. One is flexible connection, that is, the two parts are connected by a coupling, and the other is rigid connection. The high-strength bolts are used to connect the rigid connecting piece of the generator to the diesel flywheel disc. Currently, diesel generator sets on the market use more rigid connections.
After the diesel engine and the generator are connected, they are installed on the common chassis, and then they are equipped with various sensors that provide maintenance effects, such as water temperature sensors. After these sensors, the operating status of the diesel engine is displayed to the operator intuitively, and with these sensors , You can set an upper limit.
When the limit value is reached or exceeded, the control system will give an alarm in advance. If the operator does not adopt a method at this time, the control system will actively stop the unit. The diesel generator set adopts this method to achieve self-maintenance.
The sensor has the effect of receiving and feeding back various information. The real display of these data and the maintenance function is the control system of the diesel generator set. The control screen is generally installed on the generator, called a backpack-type control screen, and some are placed on a separate screen. In the operating room, it is called a split-type control screen. The control screen is connected to the generator and sensors through cables, which separately show the electrical parameters and diesel engine operating parameters.
In addition, the generator set also has a chassis, a coupling, a radiator, and a fuel tank, and some are also equipped with a muffler and a cover.
