How can we accurately determine the fault of a diesel generator set? Any equipment that has been used for a long time will inevitably experience more or less accidents, and diesel generator sets are no exception. When damage occurs, how to correctly determine diesel generator set accidents? Today I will explain it specifically for you.

1、 Predicting faults should be analyzed as a whole, and troubleshooting should be comprehensive. The various systems, components, and parts of a diesel generator set are closely related. If a component, device, or part is damaged, it will inevitably involve other systems, components, or parts. Therefore, it is not possible to view a damaged situation in isolation, and it is necessary to analyze the cause of the fault as a whole and promptly eliminate the fault.

2、 When searching for damage to diesel generator sets, dismantling should be minimized as much as possible. When solving faults, it is not allowed to blindly disassemble the components of the diesel generator set. Before disassembly, it is necessary to understand the composition, working principle, accident location, etc. of the diesel generator set. Only on the basis of scientific and careful analysis can disassembly be carried out. For example, in the operation program of a diesel generator set, if a fault situation of burning oil is found, if the cause or damage to a certain part is not identified and the oil is burned, blind disassembly and assembly may not only prolong the time for clearing the fault, but may also cause changes in the relative position of other components. Therefore, when solving faults in diesel generator sets, it is important to identify which parts or devices are damaged before repairing them to avoid blind tampering. The correct approach is to minimize the disassembly and assembly of diesel generator components when searching for damage.

(1) Look at the external characteristics of the diesel generator set during operation, such as whether the exhaust situation of the exhaust pipe is abnormal; Is the oil color normal; Is there any leakage of diesel in the fuel system; Whether there is water seepage or oil leakage in the cooling device and lubrication system; Is there any abnormality in the various instrument indications of the diesel generator set; Whether the nuts of each moving component are loose, and whether the starting circuit of the diesel generator is wired accurately; Check for any short circuits or other conditions in the internal wiring of the generator control cabinet.

(2) Listen: Specifically, listen for abnormal noises during the operation of the diesel generator set, such as whether the explosion sound of diesel during combustion in the combustion chamber is uniform;; Is there any abnormal impact sound from the piston, connecting rod, and main shaft during the operation of the diesel generator; Check for abnormal noises in the gears of the intake and exhaust doors and diesel generator during regular rotation.

(3) Check whether the temperature of each exhaust pipe after starting the diesel generator set is consistent, and whether the generator casing is too high; Is the temperature of the upper and lower water pipes of the water pump consistent; Is the temperature of the oil pipe or oil housing the same as the indication on the oil temperature gauge; Is there any abnormality in the vibration of the cylinder body.

(4) Smell: Whether there is a burnt smell in the diesel generator set during the power supply process, such as the internal circuits and components of the generator control cabinet, as well as the stator and rotor inside the generator; Does the diesel generator have a smell of burning engine oil.

3、 When troubleshooting accidents, it is necessary to classify and search for major devices of diesel generator sets. The generator consists of a stator, rotor, automatic voltage regulation system, and transmission spray system. The relationship between the stator and rotor is that the generator rotor needs to be fed with direct current to form a fixed magnetic pole. When the rotor rotates, the stator cuts the magnetic field lines and generates AC voltage. The function of the generator automatic voltage regulation device is to increase (or decrease) the excitation current of the generator load, so as to maintain a constant voltage at the generator terminal.

The above correct diagnosis of diesel generator set faults is recommended, hoping to be helpful to you.
