1
Abnormal Operation of Mechanical Components
- Faults manifest as abnormal noises, jamming, or discontinuous movements
- Core causes include insufficient lubrication of critical parts leading to accelerated wear
- Long-term high-load operation causes loosening or deformation of bearings, gears, and other components
- Foreign objects entering operating gaps cause jamming
2
Unstable Hydraulic System Pressure
- The hydraulic system is the core of the equipment's power system
- Common faults include insufficient pressure or excessive pressure fluctuations
- Caused by insufficient hydraulic oil purity, clogged oil passages, or worn seals
- Loose pipe connections lead to hydraulic oil leakage
- Aging hydraulic pumps or valve malfunctions result in unstable pressure control
3
Electrical System Signal Failure
- Failures manifest as start/stop malfunctions, abnormal indicator lights, or unresponsive action commands
- Often caused by aging or damaged wiring and poor contact
- Decreased sensor sensitivity or contamination prevents accurate signal transmission
- Controller malfunctions can prevent command execution
4
Material Jamming / Channel Blockage
- Common failures in material handling include jamming or channel blockage
- Mainly due to excessive material input, irregular shapes, or hard foreign objects
- Unremoved debris from inner walls of feeding channel obstructs material passage
- Mismatch between feeding rhythm and equipment operation causes material accumulation
