I. Deterioration of Key Performance
Weakened excitation force: Compaction effect is significantly worse, requiring repeated compaction to achieve the original density.
Speed control failure: Unable to maintain stable operating speed, exhibiting abnormal fluctuations or stagnation.
II. Abnormal Mechanical Structure
Bearing condition: Periodic abnormal noises (such as "clicking"), temperature exceeding 80℃, or increased vibration amplitude.
Transmission system: Gear wear exceeding 30%, shaft components showing cracks or bending deformation.
III. Hydraulic system failure
Abnormal hydraulic fluid: Significantly reduced hydraulic fluid volume in a short period, cloudy fluid containing metal shavings.
Unstable pressure: System pressure fluctuations exceeding 10%, leading to discontinuous operation.
IV. Electrical system problems
Control failure: Operation command response delay exceeding 2 seconds, fault indicator repeatedly illuminated.
Aging wiring: Damaged insulation causing leakage, unstable signal transmission.
