1.0 PURPOSE:
To describe a standard operating procedure for breakdown rectification of reactors.
2.0 SCOPE:
The standard operating procedure describes in detail the method of breakdown rectification of reactors.
3.0 RESPONSIBILITY:
The responsibility of breakdown rectification of various reactors lies with the staff of rank not lower than maintenance supervisor 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:
4.1.0 Agitator failure or shaft failure:
4.1.1 This can happen due to overload, misalignment of agitator or shaft, solidification of mass, corrosion or erosion.
4.1.2 Take out the agitator or shaft, repair/replace and fix it back as per SOP REPAIRING/REPLACING THE AGITATOR/SHAFT OF REACTORS
4.2.0 Damage of jacket:
4.2.1 This can happen due to more heating or cooling medium pressure or due to corrosion.
4.2.2 The jacket damage is of two types one is minor and another is major.
4.2.2.1 Minor damage:
4.2.2.1a Repair the portion that is damaged as per SOP WELDING THE DAMAGED JACKET OF REACTOR.
4.2.2.2 Major damage:
4.2.2.2a Get the jacket replaced as per SOP SENDING OUT EQUIPMENT FOR RECTIFICATION TO THE OUTSIDE AGENCY..
4.3.0 Gear box problems:
The possible gear box problems are oil seal leakage, bearings damage, worn out gears and damaged gaskets.
4.3.1 If oil seal leaks, replace the oil seal as per SOP REPLACEMENT OF OIL SEALS OF GEAR BOXES.
4.3.2 If bearings are damaged, replace the bearings as per SOP REPLACEMENT OF BEARINGS OF PROCESS / UTILITIES / LABORATORY EQUIPMENT.
4.3.3 If gears are worn-out, send the gear box for repairs as per SOP SENDING OUT EQUIPMENT FOR RECTIFICATION TO THE OUTSIDE AGENCY.
4.3.4 If gaskets are damaged, replace the same as per SOP REPLACEMENT OF GASKETS OF PIPE LINES/PUMPS.
4.4.0 Coupling bolts damage/V-belts damage/worn-out gland packing:
4.4.1 Due to misalignment of shafts, coupling bolts will be normally damaged.
4.4.2 After rectification of misalignment of shafts replace the damaged coupling bolts as per SOP REPLACEMENT OF COUPLING BOLTS OF REACTORS.
4.4.3 If V-belts are damaged, replace the same as per SOP REPLACEMENT OF V-BELTS OF REACTORS, VACUUM PUMPS, COMPRESSORS, AIR COMPRESSORS, CENTRIFUGES, BLOWER ETC..
4.4.4 If gland packing is worn-out, replace the same as per SOP replacement of gland packing of pumps and reactors.
4.5.0 Burning of motor/damage of motor bearings:
4.5.1 If motor is burnt out, get the motor rewound.
4.5.2 If motor bearings are damaged, replace the same as per SOP REPLACEMENT OF BEARINGS OF PROCESS / UTILITIES / LABORATORY EQUIPMENT.
5.0 RECORDING:
The responsibility of recording breakdown rectification in the history card as per SOP lies with staff of rank not lower than the maintenance Engineer.
