Diesel generator device.
Although diesel generators appeared in the 19th century, the demand for them is quite wide today. Yes, the device itself has seriously evolved - initially the diesel was a device weighing a ton, the efficiency of which was only 27% (for comparison, modern diesel generators have an efficiency in the region of 70-80%), which, however, exceeded the efficiency of all machines that existed at that time .
A diesel generator is a device that generates electrical energy due to the mechanical energy of rotation of the shaft of a diesel engine. At the same time, there are both stationary and mobile (mobile) generators. At the same time, it makes sense to get acquainted with the characteristics and appearance of this or that generator model directly in the store or use for this a specialized site .
Types of diesel generators
The generators also differ in their power and, accordingly, the field of application. Generators used as back-up power supplies are generally low-power and most often use an air-cooled system. More powerful generators run on a liquid-cooled system and are used more often as the main source of electricity.
It should be noted that air-cooled systems generate a lot of noise and are recommended to be used primarily outdoors. However, they are more mobile. After all, powerful diesel generators with a liquid cooling system are stationary. They are often used as the main source of electricity in cottage villages, construction sites, and even shopping and office centers.
Generator characteristics
The key characteristics of generators are: power, phase, current frequency, motor type, cooling and some others. The power range of a diesel generator can range from 2 to 3000 kW, and the indicator is also directly related to efficiency. The phase index is important for the selection of connected devices. Only single-phase appliances can be connected to a single-phase generator. The engine of a diesel generator is significantly superior in performance to engines of gasoline generators, and the service life is about 250 thousand hours.
Currently, such a service as buying and even renting diesel generators is provided by a number of companies. It is better to choose the necessary model taking into account all the features of the room in which the generator is going to be used.
