How to Identify Whether a Diesel Generator is Refurbished?

Due to the widespread use of diesel generators, more and more enterprises are using diesel generator sets as temporary emergency power sources. The quality of diesel generators on the market varies, and some businesses even refurbish them as new diesel generator sets. Let me share with you how to distinguish between a new diesel generator and a refurbished one when purchasing a high-power diesel generator.

Firstly, understand the components of a diesel generator set, which mainly consist of four parts: diesel engine, generator, control system, and accessories. Among them, the most important parts are the diesel engine and generator. As long as you do a good job in distinguishing between these two aspects, you will basically not be confused.

The most important part of the diesel engine is the power part of the diesel generator. It is very important. If you unfortunately buy a poor quality diesel generator, the loss will be severe. Diesel engines generally have rules to check, and the purchase of a generator set must be accompanied by a nameplate, which is equivalent to the generator's ID card. A generator without a nameplate is equivalent to a black house. And you can also check the machine's nameplate by querying the manufacturer based on the nameplate. The machine nameplate number can be consulted with the manufacturer.

The method of distinguishing the colors of diesel generators: Some replicas of the original diesel generator have different colors from the generator, while refurbished engines are painted, so the color of the unit is the same. Therefore, when seeing a unit with the same color from any angle, attention should be paid. It is difficult for refurbished machines to achieve the same paint finish as the original factory.

The function of a generator is to convert the power of a diesel engine into electrical energy, which directly affects the quality and stability of the output power. Generator section. As long as you can distinguish that the stator coil of the generator is made of all copper wire, the lifespan of copper-clad aluminum core wire is much lower than that of all copper wire. The stator coils were originally made of all copper wire, but with the improvement of wire making technology, copper-clad aluminum core wire has emerged. Different from copper plated aluminum wire, copper-clad aluminum core wire is made of copper-clad aluminum using a special mold during wire drawing, with a much thicker copper layer than copper plated wire. The use of copper-clad aluminum core wire for generator stator coils does not make much difference in performance, but its service life is much shorter than that of all copper wire stator coils

Other accessory control systems, as soon as you open and look inside, you can tell if it's a second-hand or new machine. Needless to say, the appearance and inside of the new machine must be the same. Touch the smoke exhaust pipe with your hand to see if there is much black material inside. How long does it take to renovate the machine. Start the diesel generator and check the instrument: When the refurbished generator starts, the temperature in the water tank rises slowly, while the new unit rises quickly. (The temperature of the water tank is similar to that of the diesel engine. If there is a temperature observation instrument, you can check the factory documents)

When purchasing a diesel generator set, it is important to have a clear understanding of the unit's factory condition, brand, model year, place of origin, and exterior details.

Dingbo Power was founded in 1974 and is one of the earliest manufacturers of generators and diesel generator sets in China. If you want get more information, please feel free to send email to sales@dieselgeneratortech.com we will pay highly attention on your question.
