Here are the tips for identifying the new and old generator sets!

Many users are very worried about being deceived during the procurement of generator sets, and are afraid of renovating old equipment and impersonating new equipment. According to the experience of some technicians and veterans of Haixing Power, to identify the new and old levels of old diesel engines, one question, two look, and three tests, and the main method is to determine the newness and old diesel engines.

Question 1: I ask about the purchase time, purpose and reason for the diesel engine, the repair situation and what major parts have been replaced, and what problems are there in use, etc., so as to have a relatively comprehensive solution to the machine.

Second look: First, check whether the model is an out-of-date model, then check the new and old degree of the diesel engine from the appearance, check whether the parts are complete and whether there is any damage.

The third test: It is the test machine. The specific method for the diesel generator set is

1. Rotate the crankshaft and make the oil supply pump supply oil. If the injector makes a crisp sound from the injector, it means that the performance of the plunger pair and the injector is good; if there is no abnormal sound in the gear room, it means that the wear of the gear is not serious.

2. Shake the flywheel up and down, if there is no sound or obvious shaking, it means that the gap between the main journal of the crankshaft and the bearing shell is not large; if there is no clicking sound, it means that the wear between the journal of the crankshaft connecting rod and the bearing shell is not serious.

3. Decompress the cylinder and shake the crankshaft. When the decompression is removed, if the piston rebounds greatly and the flywheel rotates rapidly, it means that the wear level of the cylinder liner, piston, and piston ring is small. At this time, the reading of the oil pressure gauge should not be less than 1 or the oil pressure indicates that the red float can rise quickly, and the manual pressure float should be laborious.

4. It is easier to start the diesel engine, the exhaust is colorless or light gray, the speed is stable and there is no noise, which means that the diesel engine is in good technical condition.

Through the above methods, the advantages and disadvantages of old diesel engines can generally be distinguished. On the one hand, we can determine whether the other party is a refurbished machine for sale. On the other hand, if we are purchasing second-hand equipment, we can also make an estimate of the price of the old diesel generator set through the above identification.
