During the operation of the diesel generator set, occasionally a high-frequency, sharp, and continuous “squeak -” sound is made. When the fuel is rushed, the sound is more prominent, which is caused by the slip of the pulley.
①The belt tension of the fan or air pump is insufficient.
②The belt has been stretched after long-term use and has not been replaced in time.
⑵ Diagnosis and treatment methods
①If there is a “squeak–” noise during the operation of the generator set, and when the clutch pedal is stepped on, the accelerator lightly blows, and the noise changes with the sudden change of speed, it can be considered as belt slip.
②Stop the engine and turn off the flame, press the belt with your fingers. If the sinking amount exceeds 15mm, the belt is too loose and should be adjusted.
