A pneumatic conveying system preventive maintenance schedule lists the checks and jobs done on the equipment at fixed intervals, how long each takes, and in what order of frequency, so problems are found before the pneumatic conveying system fails. This page gives the schedule used in the PlantOps360 task library for pneumatic conveying system (dense or dilute phase), which follows common industry practice for general-purpose equipment. It is also searched for as pneumatic conveying, vacuum conveying, dilute phase conveying, dense phase conveying.
The maker’s manual and your site safety procedures always come first where they differ. Intervals set by law differ by state.
Pneumatic conveying system preventive maintenance schedule and checklist
| How often | Task | Estimated time |
|---|---|---|
| Daily | Check air supply pressure, line pressure and conveying cycle times; check for blockages or leaks | 5 min |
| Weekly | Check filters at the receiver; clean or blow back; check diverter valves | 20 min |
| Monthly | Check rotary valves, seals and blower oil or belts | 30 min |
| Quarterly | Inspect pipe bends and wear points; check pipe couplings | 60 min |
| Half-yearly | Replace filter elements as differential pressure indicates; check gaskets | 90 min |
| Annual | Inspect pipelines and vessel internals; test pressure relief devices and instruments | 240 min |
Pneumatic conveying system maintenance frequency and yearly workload
At the estimated times, one pneumatic conveying system needs about 65 hours of preventive maintenance a year. The biggest single job is “Inspect pipelines and vessel internals; test pressure relief devices and instruments” at 240 minutes, done annual. Multiply by the number of units you have to see the workload for your plant.
| Frequency | Tasks | Time per round | Hours per year |
|---|---|---|---|
| Daily | 1 | 5 min | 30.4 h |
| Weekly | 1 | 20 min | 17.3 h |
| Monthly | 1 | 30 min | 6.0 h |
| Quarterly | 1 | 60 min | 4.0 h |
| Half-yearly | 1 | 90 min | 3.0 h |
| Annual | 1 | 240 min | 4.0 h |
What goes wrong on a pneumatic conveying system without preventive maintenance
- Blocked or worn pipelines and bends
- Rotary valve and seal wear
- Filter blinding at the receiver
- Blower and air supply faults
What to watch between services
- Line and air supply pressure
- Conveying rate
- Receiver filter pressure drop
Safety and statutory notes for pneumatic conveying system maintenance
Many powders are combustible. Check the explosion vents and earthing of the system on the schedule.
