Diesel generator set failure have certain signs, some signs can be heard, generator manufacturers staff summarized the following rules, to help you master the sound to judge the method of unit failure. In the early stage of diesel generator development, the noise, black smoke, can only be used in the need for large traction of agricultural machinery, with the development of diesel engine technology, many imported cars now have diesel engine models to choose from.
The well-designed diesel engine sounds much more pleasant, because it is structurally different from a gasoline engine, so it is easy to tell where the fault is going through some characteristic sound. (1) Diesel engine regular continuous sound, generally rotating parts have a fault.
If there is a continuous knock, often occur struck in timing gears, flywheels and other parts.
(2) Diesel engine issued irregular intermittent noise, generally engine accessories have problems, such as generators, starters, air compressor, pumps, etc., installation is not secure or internal scratch.
(3) Diesel engine rotation of a ring of noise once, generally related to the crankshaft parts, such as pistons, piston pins, piston rings and connecting rod bearings, such as faulty.
(4) Diesel engine every two turns of the noise, generally is associated with the camshaft parts have fault, such as valves, pushrods, valve springs and timing gear stoic gear damage. Through the above introduction, we can have a general understanding of the sound of the unit, daily operation once the abnormal sound of power generation can be simply judged which part of the unit is out of the question, maintenance work more targeted.
