Troubleshooting: Common Issues & Solutions
Q1: Pump fails to build pressure or pressure is insufficient --what are the root causes and fixes?
Systematic diagnosis:
- Control system failure: Check FR control valve--if the flow spool is stuck (due to contamination), disassemble and clean with diesel (use compressed air to blow out debris); verify pilot pressure (port X) is 35 bar (adjust pilot relief valve if low)
- Internal leakage: Disassemble the pump--measure piston-cylinder clearance (normal ≤0.02 mm; replace if >0.03 mm) and check swashplate wear (allowable wear ≤0.01 mm; lap with 600-grit abrasive paper if exceeded)
- Hydraulic circuit issues: Inspect the main relief valve--if the valve seat is damaged, replace the valve core; check for leaks in pressure lines (a 1 mm leak can reduce pressure by 50 bar)
Q2: Excessive noise ( ≥85 dB) during operation--how to diagnose?
Classify by noise type and address:
- Whistling noise: Caused by cavitation--check suction line for blockages (clean 100 μm strainer if pressure drop >0.5 bar) or air leaks (tighten flange bolts to 85 N*m or replace O-rings); ensure oil level is ≥2/3 of the tank
- Knocking noise: Indicates mechanical wear--disassemble to inspect bearing clearance (normal ≤0.03 mm; replace if >0.05 mm) or swashplate hinge pin looseness (retighten to 60 N*m)
- Harmonic noise: Caused by mismatched motor-pump resonance--adjust motor speed by ±50 rpm or install a vibration damper on the coupling
