IE B037TREATMENT REPORTS ON TWO COMPRESSORS · 10.06.2002
PKS-3.5 and PKSD-5.25 compressors: output increased without disassembly
Time to reach operating pressure shortened on both machines, pressure in the lubrication system rose. 75 % — output of PKS-3.5, time to reach 7 kgf/cm² 35 → 20 s; 43 % — output of PKSD-5.25, time to reach 7 kgf/cm² 20 → 14 s; 1–2 kgf/cm² — lubrication system pressure, 1–2 → 3 kgf/cm² on both compressors (2002).

Key results
| COMPRESSOR | CONDITION BEFORE TREATMENT | WHAT WAS MEASURED |
|---|---|---|
| PKS-3.5 | Worn · build-up to 7 kgf/cm² in 35 s · lubrication system pressure 2 kgf/cm² | Time to build up excess pressure to 7 kgf/cm²; lubrication system pressure |
| PKSD-5.25 | Worn · build-up to 7 kgf/cm² in 20 s · lubrication system pressure 1 kgf/cm² | Same |
Measurements before and after treatment — both compressors
| COMPRESSOR | PARAMETER | BEFORE | AFTER | CHANGE |
|---|---|---|---|---|
| PKS-3.5 | Time to build up excess pressure to 7 kgf/cm² | 35 s | 20 s | −15 s |
| PKS-3.5 | Lubrication system pressure | 2 kgf/cm² | 3 kgf/cm² | +1 kgf/cm² |
| PKSD-5.25 | Time to build up excess pressure to 7 kgf/cm² | 20 s | 14 s | −6 s |
| PKSD-5.25 | Lubrication system pressure | 1 kgf/cm² | 3 kgf/cm² | +2 kgf/cm² |
According to the conclusion of the contractor, the output of PKS-3.5 rose by 70 % and that of PKSD-5.25 by 43 %; recalculation from the pressure build-up time gives 75 % and 43 %.

About this result:
Limits of this report: The results relate to the PKS-3.5 and PKSD-5.25 compressors treated in June 2002; on other equipment and under other operating conditions the figures may differ. The treatment was performed and the conclusion on the magnitude of the effect was drawn by one and the same contractor — NTC Stroy-Servis LLC.
