Fault Diagnosis & Troubleshooting
The pump fails to deliver flow - Common causes and solutions
No-flow or low-flow issues are typically related to suction, drive, or control problems. Troubleshoot in this order:
| Common Cause | Diagnostic Step | Solution |
|---|---|---|
| Clogged suction filter or line | Check suction pressure (should be ≥ -0.8 bar; negative pressure indicates blockage) | Clean or replace suction filter; flush suction line |
| Air in the hydraulic system | Bubbles in the return line oil; pump makes a whistling noise | Bleed air from the pump and system; check for loose suction connections |
| Drive shaft not rotating | Motor runs but pump shaft is stationary; coupling is damaged | Replace drive coupling; repair or replace motor if faulty |
| Control mechanism stuck (e.g., pressure compensator) | Pump displacement remains at 0% despite demand; control valve is unresponsive | Disassemble and clean control valve; replace worn springs or seals |
| Worn piston or cylinder block | Low flow even at maximum displacement; metal particles in oil | Replace piston/cylinder block assembly; flush system and replace oil |
The pump experiences excessive pressure fluctuations - How to resolve this
Pressure fluctuations (±10 bar or more) disrupt system performance. Common causes and fixes:
- Unstable Control Signal (Electro-Hydraulic Models): Cause: Electromagnetic interference (EMI) or faulty sensor. Solution: Install EMI filter on the control signal line; ground the pump and controller; replace faulty sensor.
- Worn Pressure Compensator Valve: Cause: Valve seat wear or spring fatigue leads to inconsistent pressure regulation. Solution: Replace pressure compensator valve; recalibrate pressure setpoint.
- Air in the System: Cause: Air bubbles compress and expand, causing pressure spikes. Solution: Bleed the system thoroughly; check for suction line leaks.
- Oversized System Volume: Cause: Large hydraulic accumulators or oversized lines delay pressure response. Solution: Adjust accumulator precharge pressure; install a pressure dampener near the pump.
