Crankcase Inspection of Compressor


Crankcase Inspection of Compressor
Risk Assessment:
Turn off the source and lock the button (additionally a warning TAG can be placed over the source that work is in progress.
Visit the machinery physically and ascertain any hazard during working.
Write on daily White board that work is in progress on Compressor No. 1 etc
Tools:
During visit to machinery remind in mind what proper tools which you will need during crankcase inspection.
We use the following tools during opening up of Crankcase.
·         17 milimeter Open and Close end spanner.
·         22 milimeter Open and Close end spanner.
·         A ball peen hammer
·         A flat screwdriver
·         Red RTV silicone
·         Adjustable spanner
·         Torque spanner with appropriate socket (we use 22mm)
·         Cloths for cleaning and empty bucket for pouring the dirty crankcase oil.
Commencement of Work:
Open up the Crankcase door by 17mm spanner. Remove the nut; door such that no harm to gasket. Check that there is no particle of metal in the sump. Check the Crank pin bearing nuts( by using 22mm spanner). If they are loosen tight it with the help of torque spanner at appropriate torque. Drain the Crankcase oil by removing the square nut. Clean the Crankcase and then pour some clean oil to drain it again. Tightened the square nut and replenish crankcase with new oil (Castrol SN 100). Our marking of compressor is 4cm (Min Level). Assemble the crankcase door and nut as in reverse process.  Start the Compressor  for trail run Check the ampere, Temperature, pressure of 1st , 2nd, water , oil gauge and any unusual sound if any. If the doubt persist stop the compressor immediately and check the compressor again.
