Diesel engine and parts
The 200kw generator set has abnormal noise, how should the owner determine the source of the fault?
May 20, 2022
If there is abnormal noise in the 200kw diesel generator set, it means that some part of the unit is faulty. The user should pay attention to observe some abnormal noises of the diesel generator in time, so as to find and solve the problems that will or have occurred in the generator in time, so as to extend the 200kw generator set. service life.
In the process of use, if the 200kw diesel generator set has abnormal noise, it means that some part of the generator set is faulty. The reason is the uncoordinated work between the parts, which makes the machine make various abnormal mechanical impact sounds. Below, Dingbo Electric will introduce you how to judge the fault source of the unit through these abnormal sounds.
1. The unit emits irregular intermittent noises, generally due to the failure of the engine accessories, such as the generator, starter, air compressor, water pump, etc.
2. The 200kw diesel generator set makes regular and continuous sounds, usually because the rotating parts are faulty. If there is a continuous knocking sound, it often occurs in the timing gear, flywheel and other parts.
3. When the 200kw generator set is running, there is a rhythmic and crisp "dangdang" metal knocking sound. Generally, the fuel injection timing gear is not installed correctly, the fuel injection pump outlet valve belt is seriously worn or the fuel supply time is not adjusted properly.
4. The abnormal noise occurs once every two revolutions of the diesel generator set. Generally, the valve, push rod, valve spring and timing gear and other parts related to the camshaft are faulty.
5. The abnormal noise occurs once when the diesel generator set rotates a circle. Generally, the parts related to the crankshaft, such as pistons, piston pins, piston rings and connecting rod bearings, are faulty.
The above is the method of judging the fault source of the 200kw generator set when there is abnormal noise. The generator manufacturer reminds: During the use of the diesel generator, the user should pay attention to observe some abnormal noises of the diesel generator in time, so as to find and solve the power generation in time. To extend the service life of the 200kw generator set
