BREAKDOWN RECTIFICATION OF BLENDER

1.0 PURPOSE:   

    To  describe  a  standard operating  procedure  for  breakdown   rectification of blender.     
2.0    SCOPE:   

    The  standard  operating  procedure describes  in  detail  the   method of breakdown  rectification of blender, which  includes gear box oilseals leakage, damage of couplings of motor and blender, motor bearings damage  and blender bearings damage. 
    
3.0    RESPONSIBILITY:    

    The  responsibility  of carrying out breakdown   rectification    of  blender lies with staff of rank not lower than the  junior  utility operator of maintenance department. 
    
    The  responsibility of preparing, reviewing  and approving  the  standard  operating  procedure lies with the  Manager  -  Maintenance,  Head of Production and Head of QAD respectively.
    
4.0    METHOD:
    
4.1    Damage of gear  box oilseals/bearings:
    
4.1.1    Carryout replacement of oil seals and bearings as  per  SOP REPLACEMENT OF OIL SEALS OF GEAR BOXES and SOP/ REPLACEMENT OF  BEARINGS OF  PROCESS / UTILITIES / LABORATORY EQUIPMENT.respectively.   
       
4.2    Damage of couplings of motor and blender: 
    
4.2.1    Carry out replacement of couplings as per SOP REPLACEMENT OF DAMAGED COUPLINGS/PULLEYS OF REACTORS, PUMPS, MOTORS AND GEAR BOXES..
    
4.3    Damage of motor bearings:
    
4.3.1    Carry  out  replacement of bearings of motor as  per  SOP  REPLACEMENT OF  BEARINGS OF  PROCESS / UTILITIES / LABORATORY EQUIPMENT.
    
4.4    Damage of Blender bearings:
    
4.4.1    Isolate the equipment electrically.
    
4.4.2    Remove gear box from the equipment.
    
4.4.3    Remove Blender shell couplings using puller.
    
4.4.4    Give a support to the Blender shell.
    
4.4.5    Remove the plumber blocks and replace both the bearings.
    
4.4.6    Fix the plumber  blocks.
    
4.4.7    Fix the coupling to the Blender shell.
    
4.4.8    Fix the gear box.
    
4.4.9    Restore the power supply to the equipment.
4.5    Record the details in the history card.
    
5.0    RECORDING:
    
    The  responsibility of recording the breakdown   rectification   in  the  history card  lies with the staff  a rank  not  lower   than the maintenance supervisor.
