On-Site Fault Finding and Commissioning
An engineer with gauges, a flow meter and a thermal camera on the machine, to find why a circuit is slow, hot or drifting, and to set a new circuit up properly.
Features
- Measurement first: pressure at test points, flow where it can be taken, and case drain flow, which usually identifies the worn component within an hour.
- Thermal readings across a valve bank show where power is being lost as heat, which is often a partly open relief rather than a failed pump.
- Relief, compensator and port relief settings are recorded before anything is adjusted, so the machine can be put back if the fault lies elsewhere.
- Commissioning of a new circuit covers filling through filtration, bleeding, setting pressures, and stroking every actuator under observed conditions.
- The visit ends with a written record of settings and readings, which becomes the baseline for the next comparison.
Specifications
| Figure | Typical range | Unit | Why it matters |
|---|---|---|---|
| Symptom reported | slow boom, oil at 85 degrees C | directs which measurements are taken first | |
| Measured pressures | pump 210, relief cracking 195 | bar | separates a pump fault from a relief fault |
| Measured flow | 62 against 80 rated | l/min | quantifies the loss instead of describing it |
| Case drain flow | 6 against 2 expected | l/min | the quickest indicator of internal wear |
| Settings recorded | before and after, per valve | lets the machine be returned to its original state |
