1. Causes of abnormal generator noise
1. The vibration and abnormal noise of the diesel engine are mainly caused by the weak support of the diesel engine.
2. The abnormal noise occurs every two revolutions of the diesel engine (i.e. one operating cycle of the diesel engine). The cause of the failure mainly lies in the parts related to the camshaft, such as the valves. , push rods, valve springs and valve springs, time gears, etc.
3. An abnormal noise occurs once per revolution of the diesel engine. The cause of the failure mainly lies in the parts related to the crankshaft, such as pistons, piston pins, piston rings and connecting rod bearings.
4. Abnormal noises occur continuously, and the abnormal noises have a certain pattern. Most faults occur on rotating parts. For example, continuous knocking noises often occur on dparts such as flywheels and timing gears.
5. Abnormal noises occur intermittently and the noises are irregular. The main cause of the failure is diesel engine accessories, such as generators, Weichai accessories, water pumps, air compressors, starters, etc. ., are installed loosely or internally. There are scratches and so on.
2. How to judge common abnormal noises:
1. The whole machine vibrates and makes noise. After starting the diesel engine, there is an irregular vibration noise, which intensifies as the engine speed increases. The main reasons are: the diesel engine supporting bolts are loose or the suspension is broken, the diesel engine mounting position is incorrect, resulting in the crankshaft; and the first drive shaft on different axes; suspense stamp partsdamaged diesel engine ion, etc. If the diesel engine vibrates, it should be directly checked and eliminated for the above reasons.
Precautions for using generators: The use of generators should be protected from rain, and they should be checked in time after being exposed to rain. If there is a defect, it must be repaired in time!
