Batch reactor

Hello....after a long break of our practical work because of  our exams n presentations we were unable to post the recent interesting happenings in our batch reactor pilot plant....

     Its not the meaning that we were not working on that..We worked on interesting concept of  looping .I am saying interesting as it was done previously by the pilot plant developers.After some days the inlet valves are not working.

     We found relay number 12 also not working....so we traced whole loop and finally found one bug in card channel which itself not producing 24 v DC.Now we changed card number and channel number.Now as relay number 12 is working he Inlet valve center one is working now.

     Second problem i found when whole loop is ok but simple fuse in Marshalling cabinet is not working means just blown. we replaced it and checked ,the valve is working now.

      U might think its a just routine maintenance problem but in our opinion if we are able to find those problems and we solve it then it clears our ideas of field instrumentation specifically...I already posted diagram of this batch reactor so you can check which valves were not working(inlet valves).

  Relay card picture also posted in previous blog..

    

Thanks to all...
