IE A101TEST REPORT DATED 4 NOVEMBER 2000
Industrial compressor: bore wear offset, no overhaul needed
Scoring on the cylinder bores became shallower, the damaged bore was restored, repair was not required. 2.5× — score depth on the cylinder No. 2 bore, 0.05 → 0.02 mm (2000).
with signatures and stampmeasurements outsourced to an external workshop, an independent expert engaged for assessment
Key result
| MACHINERY AND COMPONENTS | CONDITION AT START OF TESTING | WHAT WAS MEASURED |
|---|---|---|
| Three-cylinder compressor, working pressure up to 7 atm | Unfit for service: heavy oil consumption, low compression | Oil consumption, receiver filling time |
| Cylinder No. 2 bore | Destroyed over a significant area of the upper section, score depth about 0.05 mm | Score depth |
| Cylinder No. 1 bore | Three scores, perceptible to the finger | Surface condition |
| Shop pneumatic hammers | Frequent seizures, erratic operation in a dusty and aggressive environment | Tool operation, assessment |
Cylinder bores — condition before and after the test
| COMPONENT | BEFORE TREATMENT | AFTER 121 H OF OPERATION |
|---|---|---|
| Cylinder No. 2, upper section of the bore | Bore destroyed over a significant area, score depth about 0.05 mm | Greatest score depth 0.02 mm, bore largely restored |
| Cylinder No. 1, bore | Three scores, perceptible to the finger | The former scores can no longer be felt |
Score depth measurements were carried out by an external organisation — Zakład Mechaniki Pojazdowej “AUTO-SZLIF-SPRAWKA”, Częstochowa.
Compressor operating parameters
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Engine oil consumption | 100 cm³ per 8 h of operation | 100 cm³ per 24 h of operation |
| Receiver filling time to 4.5 atm | 3 min | 1 min 30 s |
Before the test the piston rings of all pistons were replaced; ring replacement has no effect on the geometry of the cylinder bores.

About this result:
Limits of this report: The results relate to a three-cylinder industrial compressor with a working pressure of up to 7 atm at the Prywatna Huta “ALMET” plant (Częstochowa, Poland); on other units and duty cycles the figures may differ. The report was signed, among others, by a XADO representative; the score depth measurements were performed by an external workshop, and an independent expert was engaged for the assessment.
