The causes of gasoline generator set faults are usually caused by various components. Different faults explain different phenomena. To eliminate the fault, you must first find out the cause of the fault. In reality, you can find out by seeing, listening, touching, smelling, etc. Gasoline engine is very popular, so as to find problems, solve problems, and eliminate malfunctions.
The general rules for judging gasoline engine failures are: combining layout, connecting affair, clarifying the phenomenon, combining reality, simple to complex, from the outside to the inside, section by system, and find the cause.
In the long-term reality of sales and wholesale, people have explored and summed up a set of inspection methods of "one look, two listens, three touches, and four smells". Through instrument monitoring and human feelings, they can observe and judge the operation of gasoline engines.
Running very
After a gasoline engine has been running for a long period of time, a malfunction occurs, and the following phenomena will usually be encountered.
(1) The sound during operation is very unusual. The gasoline engine makes unacceptable percussive sounds, blasting sounds, bragging sounds, exhaust sounds, periodic friction sounds, etc. during operation.
(2) Very running gasoline engine is not easy to start, violent vibration occurs during the work, the load cannot be moved, the speed is unstable, etc.
(3) The surface is very white smoke, black smoke, and blue smoke from the exhaust pipe of the gasoline engine, and oil leakage, water leakage, and air leakage in various systems.
(4) The temperature is very high, the oil temperature or the cooling water temperature is too high, the bearing is overheated, etc.
(5) The smell is very bad. When the gasoline engine is running, it emits odor, burnt smell, smoke smell and other odors.
After the gasoline generator set is in operation, after discovering the above-mentioned abnormal phenomena, it is necessary to conduct careful observation, document the failure phenomenon, analyze and determine the location and cause of the failure. Occasionally, a fault may have several extraordinary phenomena. For example, after the high-pressure oil pump is worn out, it can not only explain the start-up difficulty, but also the insufficient output power, but also the unstable low-speed operation. Occasionally, an extraordinary phenomenon may be caused by several failures. Therefore, abnormal phenomena occur during gasoline engine operation, and we must carefully investigate the reasons for the abnormal phenomena. This requires us to be good at analyzing, reasoning, and judging, grasping the true colors through the phenomenon, and finding out.
The cause and location of the fault, and remove the fault
