How to Distinguish Whether Diesel Generator Set is Refurbished Engine?

In recent years, with the development of society, people's lives and production have become increasingly dependent on electricity. Many communities, units, and enterprises have purchased diesel generator sets as emergency backup power sources. The quality of diesel generators on the market varies, and some businesses even confuse old and new. It should be noted that a diesel generator set is expensive. Therefore, users must identify reliable manufacturers when purchasing, and not be deceived into buying second-hand or refurbished machines just for the sake of cheapness. In this article, the generator manufacturer - Dingbo Electric Power - will teach you how to cleverly distinguish whether the diesel generator set you purchase is a refurbished machine.

1. Observe the paint of the unit

This is the most intuitive way to determine whether the unit has been refurbished or repainted. The original paint on a typical diesel generator set is relatively uniform and shows no signs of oil flow. In addition, the accessories of a new diesel generator set are mostly in their natural color, which is different from the body color; Refurbishment machines spray the entire machine in a single color, and it is difficult to achieve the same paint finish as the original factory, which is easy to identify.

2. Check the diesel engine nameplate and other labels

The diesel engine is the most important part of the generator set. It is the power part of the diesel generator set. When purchasing a generator set, it must have a nameplate, which is equivalent to the ID card of the generator. A generator without a nameplate is like a black house. In addition, the labels of units that have not been refurbished are usually affixed in place at once, without any feeling of being lifted, and all labels are not covered by paint. The wiring pipe, water tank cover, and oil cover are usually assembled and tested before arranging the control wiring pipe during the assembly of the generator set. If there are obvious black oil marks on the oil cover, it is suspected that the diesel engine has been refurbished. Generally, a brand new water tank cover is very clean, but if it is a used machine, the water tank cover usually has yellow marks, which users should also carefully check.

3. Observe accessories and control systems

For other accessory control systems, as long as you open and look inside, you can tell if the machine has been refurbished. The appearance of the new machine must be consistent with the inside. Touch the smoke exhaust pipe with your hand to see if there are many black substances inside, it is a refurbished 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.

4. Check the engine oil

If it is a brand new diesel generator set, its internal components are all new, and the engine oil will not turn black after a few turns. If it is a diesel generator set that has been used for a period of time and has been replaced with brand new engine oil, the engine oil will turn black after a few minutes of use.
