IE B036REPORT OF OJSC STAVROPOLPROEKTSTROY, 9 APRIL 2002
Compressor, no teardown: reached working pressure, pump-up got faster
The compressor again reached the valve trip pressure, the receiver began filling faster. 6 kgf/cm² — safety valve trip pressure, not reached → 6 kgf/cm² in 6 min; 33 s — time to build 5 kgf/cm² in the receiver, 4 min 30 s → 3 min 57 s (2002).
compressor treatment, 9 April 2002
Key results
| EQUIPMENT | CONDITION AT START OF WORK | WHAT WAS MEASURED |
|---|---|---|
| Compressor with receiver,<br/>SMU-2 site | Pressure of 6 kgf/cm² was not reached; build-up to 5 kgf/cm² — 4 min 30 s; air leak through the shut-off valve | Pressure build-up time in the receiver; reaching the safety valve trip threshold |
Receiver pressure build-up — before and after treatment
| PARAMETER | BEFORE TREATMENT | AFTER TREATMENT |
|---|---|---|
| Time to build 5 kgf/cm² | 4 min 30 s | 3 min 57 s |
| Safety valve trip pressure 6 kgf/cm² | not reached | reached in 6 min |
| Air leak through the shut-off valve | recorded | still present, not eliminated |
Measurements taken on the fully assembled compressor under normal service operation; 6 kgf/cm² is the trip threshold of the standard safety valve.
Commission's conclusion
Current equivalent
Revitalizant gel for compressors and bearings →
Piston, screw and centrifugal compressors; rolling and sliding bearings running in an oil bath; machine-tool spindle units and slideways.
How such units are treated:
Limits of this report: The results relate to the compressor unit with receiver at the SMU-2 site of OJSC Stavropolproektstroy; on other units and under different operating conditions the figures may differ. RVS is an obsolete XADO designation, the zero-generation compounds; the current product generation is revitalizants. The treatment was performed by a XADO technology distributor.
