Progressive distributor: Diagnosis & maintenance (practical guide)
Progressive systems deliver defined quantities per cycle. The advantage: clear diagnosis via stroke sensor/limit switch. This is how you proceed in the event of malfunctions and maintenance.
Fast diagnosis (workflow)
- Visually: Leakage, loose fittings, damage?
- Medium: Viscosity/NLGI suitable? Air in the system?
- Sensor technology: Stroke sensor LED/signal, wiring, counting in HMI
- Function: Solve and encourage departures at random
Typical causes & measures
- Blockage at the distributor: Clean, replace dosing element
- Air in the system: Bleed, check refill process
- Missing impulses: Sensor adjustment/defect, cable break
- Uneven delivery: Adjust quantity/interval, check cable routing
Maintenance checklist
- Weekly: visual inspection, messages in the HMI
- Monthly: pulse counting/trend, random quantity check
- As required: cleaning, filter/lubricant change according to plan
