Why are diesel generator sets widely used? What are its advantages and disadvantages?

Diesel generator set is to compress the fresh air inhaled to reach the ignition temperature of diesel, and then inject diesel to spontaneously combust to do work. Its structure is relatively simple. Important departments such as industrial and mining enterprises rely on diesel generator sets to automatically generate electricity when the city power fails to provide AC power to ensure the power consumption of communication equipment or other electrical appliances such as lighting and elevators.

Its structure is relatively simple. Important departments such as industrial and mining enterprises rely on diesel generator sets to automatically generate electricity when the city power fails to provide AC power to ensure the power consumption of communication equipment or other electrical appliances such as lighting and elevators. Diesel generator sets are widely used, mainly based on the following advantages:

       1) High thermal efficiency. High thermal efficiency, that is, low fuel consumption rate, good economy, and the highest effective thermal efficiency has reached 46%.

       2) Wide power range. The power of a single machine can be from a few tenths to tens of thousands of kilowatts, and the scope of application is large.

       3) The structure is compact, the weight is light, the ratio of the mass of the internal combustion engine to its rated power (called specific mass) is small, and it is easy to move.

       4) It is quick to start, easy to operate, and can run at full load soon after starting.

 

       When using diesel generator sets, because diesel generator sets also have certain shortcomings, users should pay special attention to regular maintenance of the generator set in order to effectively prolong the service life of the generator set. So what are the disadvantages of diesel generator sets?

       1) Higher fuel requirements. Diesel generator sets generally use light diesel oil as fuel, and the cleanliness of the fuel is very strict. It is difficult to use solid fuel or inferior fuel inside the cylinder. The user must select the appropriate fuel according to the regulations, and check the fuel regularly. If the fuel is found to be deteriorated, it should be replaced in time.

       2) Exhaust pollution and noise cause public nuisance. Since diesel generator sets are widely used in various fields of the national economy, their output and retention are extremely large, and the pollution to the environment is becoming more and more serious. Therefore, users must do a good job of diesel generator set emissions when using them. processing and noise reduction.

       3) The structure is more complex, and the machining accuracy of the parts of the diesel generator set is relatively high. When using it, lubrication should be done to prevent excessive wear of the parts and cause damage to the set.

 

       Based on the advantages and disadvantages of diesel generator sets, in recent decades, in order to improve the power, economy and reduce exhaust emissions and noise requirements of diesel generator sets, generator manufacturers have carried out research on new technologies, especially electronic technology. The diesel generator set has gained new development, and the current diesel generator set has become more and more environmentally friendly.
