Vessel PM

What is a good monthly inspection of a ammonia recirculating vessel include.

Jackryan,
A few things I think in no particular order.
- check & drain oil in oil from all drain points, oil pot, column etc.
- operation of level control, solenoids, float switches working & look ok, no moisture inside etc.
- liquid pump pressure normal
- liquid pump condition, seal, bearing monitor depending on type hermetic or open drive.
- change over liquid pump if has standby.
- gauges, pressure switch, valve condition.
- relief valve condition on oil drain pot & vessel.
- corrosion of pipe & fittings.
- 6 monthly high level safety cut out check
- 6 monthly relief outlet & pipe check for fouling/ deterioration.
- relief calibration due date
- vessel inspection due date
- insulation condition
- vessel leg condition
- sight glass or bullseye clean.
- excessive ice formation on/ around valves in case of emergency

Probably other things, see if anyone can add.
