Key result
| EQUIPMENT | CONDITION AT THE START OF TESTING | WHAT WAS MEASURED |
|---|---|---|
| PB-28 compressor | Discharge pressure 4.0 atm, elevated operating noise | Discharge pressure after each treatment stage |
Compressor discharge pressure by treatment stage
| STAGE | DISCHARGE PRESSURE, ATM | CHANGE VS. BASELINE |
|---|---|---|
| Before treatment | 4.0 | — |
| After stage 1 | 4.2 | +5 % |
| After stage 2 | 4.5 | +12.5 % |
| After stage 3 | 4.5 | +12.5 % |
Measurements were taken before treatment and after each of the three stages within one cycle; the pressure reached 4.5 atm already after the second stage.
What else changed in the unit's operation
| WHAT WAS OBSERVED | AS RECORDED IN THE REPORT |
|---|---|
| Suction vacuum | Increased noticeably after the first treatment stage |
| Operating noise | Noise of the running unit decreased |
| Oil level | Unchanged after the third treatment stage — oil loss stopped |
Assessments are those of the contractor and the customer in the report; the document gives no numerical measurements for these observations.
