Purchased two solenoids. One for use and one for spare purposes.
Troubleshoot and replace blown capacitor breaker fuse.
Working on purchasing spare fuses. Still not ordered at this time will be ordered in
October with delivery expected in Late October or early November.
Cooling water sand filter has required significant work. The baffle in the housing failed
and then the sand-filter stainless steel container seam split. Considering modification of
the system to allow removal of the sand filter. Installation of an auto-backflush of disk
filters will be required at a cost of ~$3,500 and we would want to increase the disk filters
to a two inch size (from one inch). All in the cost for this modification would be ~
$5,000 in parts and plus labor. A new sand-filter ss container runs approximately $8,000
plus a similar labor component as the modification. Guessing the labor component would
be 32 man-hours for the labor in either repair.
Troubleshooting the air compressor HMI video SCADA panel. Labor only
Installed a PLC control program to run the Air Compressor on a longer and more regular
basis. The purpose is to remove the moisture from the compressor and tank. Ingersol
Rand’s option to perform this service and operation was not cost effective.
All other standard maintenance was performed per our work order system (see attached
summary)
