Tracking number is stamped on to the casing of the compressor
From this we can track the compressors history of repairs and spares
Capture full details of compressor along with pictures prior to strip-down
Strip Down and Inspection
The compressor is completely stripped for inspection
Each component is stripped according to our strip report checklist (Condition, Size, etc.)
From these results we can determine the possible causes of failure and inform the customers to avoid repeat failures in the future e.g: liquid slugging, single phasing, overheating, etc.
Recommended Spare Parts List & Repairs
From the captured information during strip-down we then compile a full list of spares and repairs required to refurbish the compressor
Assembly
Note: Each item on our checklist is signed off by our foreman before being passed
Proceed with repairs such as cylinder rebored and re-sleeving, motor rewinds, crankshaft regrind, etc.
Requisition spares required from our in-house spares department
Assembly checked and tested
Axial Thrust
Torrques (conrod bolts, heads and covers, motor bolts, etc.)
Clearances and tolerances
Motor air gap
Motor insulation test
Thermisters are tested
Test run
Nitrogen pressure test ( minimum 2200kpa)
Oil pressure test (as per manufacturers specifications)
Running amps (using our VSD drive we can control speed and incoming voltage)
Pump-Down Efficiency test (we will only pass the compressor at a minimum 4min holding)
Capacity control (capacity regulating devices operation)
Note: We will not pass a compressor until it has been fully tested!
