Diesel Generator Structure and Selection of Engine Brand

Diesel Generator Structure

200kVA Cummins Diesel Generator

The diesel generator set is a small-scale power generation equipment, which refers to a power supply device that uses diesel as a fuel and uses a diesel engine as a prime mover to drive a synchronous generator to generate electricity. This is a power generation device with quick start-up, convenient operation and maintenance, low investment, and strong adaptability to the environment. Because of its small size, flexibility, lightweight, complete support, easy operation, and maintenance, it is widely used in mines, railways, fieldwork sites, road traffic maintenance, and factories, enterprises, hospitals, etc., as backup power or temporary power.

The modern power generator consists of a diesel engine, a three-phase AC brushless synchronous generator, a control panel, a radiator, a coupling, a fuel tank, a muffler, and a common base. The flywheel housing of the diesel engine is directly connected with the axial direction of the front section of the generator by a shoulder, and the rotation of the generator is directly driven by the flywheel by a cylindrical elastic coupling, and the connection manner is fixed by screws, so that the two The connection to a steel body ensures that the concentricity of the crankshaft of the diesel engine and the rotor of the generator is within a specified range. In order to reduce the vibration of the unit, shock absorbers or rubber shock absorbers are usually installed at the connection between the main components of the diesel engine, generator, radiator, electrical control box, and the common base.

Selection of Diesel Engine Brand and Alternator Brand

At present, there are many famous brand diesel engine for diesel generators, such as Cummins diesel engine for 20kVA to 1500kVA power generator, Perkins diesel engine for 10kVA to 2500kVA electric generator, Deutz diesel engine for 20kVA to 1500kVA diesel generator, Volvo diesel engine for 85kVA to 688kVA industrial generator, SDEC diesel engine (One of the top quality Chinese brand diesel engine) for 25kVA to 1000kVA diesel generator, Yuchai diesel engine(cooperate with MTU to produce the diesel engine) for 25kVA to 2000kVA, Chinese brand high quality Fawde brand diesel engine for 10kVA to 400kVA, Quanchai brand diesel engine & Yangdong brand diesel engine for 8kVA to 50kVA diesel generator and other famous brand diesel engine for industrial generator.

The alternator like Stamford brushless alternator, Marathon brushless alternator, Hosem brushless alternator, and Mecc Alte brushless alternator. All the alternator brands have the alternator for 5kVA to 2000kVA diesel generator. 

How to choose the diesel engine for diesel generator at the end-users side? 

1. If you want to continue uses the diesel generator or standby diesel generator for the important departments, like the hospital, bank or data center, then advise you choose the famous brand and most popular diesel engine for the diesel generator, like diesel generator powered by Cummins diesel engine or Perkins diesel engine. Because they are the two of the most famous brand diesel engine in the world, you can easy to get the maintenance and repair spare parts in each country during the diesel generator lifetime. 

2. If the diesel generator is only for standby purpose for the commonplace, then recommend choosing the SDEC diesel engine, Yuchai diesel engine or Fawde diesel engine for the diesel generator. Because the price of the diesel engine will be cheaper a lot than Cummins or Perkins diesel engine, and the quality of the diesel engine is very good enough, just maybe you cannot get the spare parts in the local city for repair or maintenance. but you can easily get the spare parts from your diesel generator supplier or Chinese diesel generator factories. 

The General diesel generator set is available in the range of 3kVA to 3000kVA. For more powerful diesel generator sets, multiple diesel generator sets can be used in parallel.
