2VM4-27/9 compressors: output increased, plant extended the treatment
Compressor performance increased, oil in the crank mechanism stopped overheating. 16 % — output of compressor OUS30D01, filling of 20 m³ from 4 min 39 s → 4 min; 19–40 % — oil temperature in the crank mechanism system, 80 → 48–65 °C (1999–2000).

Key results
| COMPRESSOR | TREATMENT | OBSERVATION | ACT |
|---|---|---|---|
| OUS30D01, OSK section | 03.08.1999 — piston group and crank mechanism | 264 h of operation in various modes, measurements before and after | 01.09.1999 |
| AKS and OSK compressors, including OUS30D01 | May 2000 — both sections | assessment of mechanism operation by the plant commission | 30.05.2000 |
Compressor OUS30D01 — 264 hours of operation after treatment
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Output — time to fill a 20 m³ air receiver from 0.2 to 8 kgf/cm² | 4 min 39 s | 4 min — output up by 16 % |
| Oil temperature in the crank mechanism system | 80 °C | 48–65 °C in various operating modes |
| Oil pressure in the crank mechanism lubrication system | dropped as the oil heated up | stabilized |
Oil temperature fell while the ambient air temperature was rising: the compressor has no oil cooling system.
Treatment of the plant compressor fleet, May 2000
| SECTION | TREATED COMPRESSORS |
|---|---|
| AKS | US71D01 · US72D01 · US76D01 · US77D01 · US79D01 |
| OSK | OUS10D01 · OUS20D01 · OUS30D01 · OUS40D01 · OUS50D01 · OUS70D01 |
The plant commission recorded a drop in temperature at the friction points with its subsequent stabilization, and restoration of output to the rated values.

About this result:
Limits of this report: The results relate to 2VM4-27/9 air compressors at the compressor sections of the Zaporizhzhia NPP; with other machines and operating modes the figures may differ. RVS is an obsolete XADO designation for zero-generation compounds; the current product generation is revitalizants.
