DRIVE TRAIN OVERHAUL AND REPAIR FEED WATER PREHEATER PUMP OVERHAULING REPORT
WWG Engineering has worked with Sembcorp to overhaul their feed-water preheater Apollo pump.
INCOMING CONDITION AND DISMANTLING
The process began with the dismantling of parts followed by a dimension and run out check. A bore check is done on the impeller and a dimension check is done on the wear ring. Masking and blasting is then carried out, as well as coating.
MASKING & BLASTING
To complete the task, a combination of techniques such as blasting, welding and machining were carried out by our team on the top sheaves.
PRIMER COATING (ONLY FOR EXTERNAL PAINTING)
To complete the task, a combination of techniques such as blasting, welding and machining were carried out by our team on the top sheaves.
EXTERNAL COATING RAL6019 PASTEL GREEN AS PER OEM SPECIFICATION
INTERNAL COATING USING CERAMIC POLYMER CN200
Finally, the reassembly is done with new consumables, ending with a pressure test.
PRESSURE TESTING MAX SUCTION PRESSURE = 5 BAR REQUIRED TESTING PRESSURE = 5 BAR X 1.5 = 7.5 BAR
