2. Common Hydraulic Piston Pump Faults & Repair Solutions

2.1 PSVL-54 Hydraulic Pump Typical Failures

• Insufficient hydraulic output pressure: Worn cylinder block, piston shoe and valve plate cause internal oil leakage, weak digging force
• Pump abnormal vibration & metal knocking noise: Scuffed friction surface generates continuous collision noise
• Pump overhigh oil temperature: Long-hour light & medium load friction leads to sustained overheating
• Internal and external oil leakage: Aging sealing parts and damaged sealing surface cause hydraulic oil spill
• Unstable flow output: Uneven component wear leads to fluctuating flow and whole machine jitter

2.2 Travel Motor Common Faults

• Travel deviation, unilateral slow moving
• Insufficient climbing torque, machine slips on slopes
• Travel motor oil leakage and abnormal running noise

2.3 Swing Rotary Motor Common Faults

• Weak swing rotation torque, slow slewing
• Swing jitter and friction knocking noise
• Swing shaft oil leakage, swing stuck stall after long continuous operation
• Swing motor overheating under continuous load

2.4 Multi-way Control Valve Faults

• Control spool blocked by hydraulic impurities
• Valve body internal leakage, slow boom & bucket action
• Overflow valve pressure abnormality
