IE A115CERTIFICATE OF FINDINGS DATED 20.12.2000
VSh-3/40M compressor: capacity increase no teardown, no shutdown
The compressor began reaching pressure faster, oil heated up less. 58.3 % — capacity by air receiver filling, 19 → 12 min; 15.2 % — oil temperature at 41 kgf/cm², 59 → 50° (2000).

Key results
| EQUIPMENT | CONDITION AND WORKING SETUP | WHAT WAS MEASURED |
|---|---|---|
| VSh-3/40M air compressor | In-service compressor of the plant; treated under normal operating conditions, without teardown and without taking the equipment out of service | Air receiver filling time, current draw, oil temperature |
Measurements on the VSh-3/40M compressor before and after treatment
| PARAMETER | BEFORE · 03.11.2000 | AFTER · 19.12.2000 | CHANGE |
|---|---|---|---|
| Air receiver filling time from 38 to 41 kgf/cm² | 19 min | 12 min | −7 min · capacity +58.3 % |
| Oil temperature at a pressure of 41 kgf/cm² | 59° | 50° | −15.2 % |
| Current draw | 70 A | 74 A | +5.7 % |
The certificate attributes the higher current to the increased capacity: the compressor reaches the same 41 kgf/cm² noticeably faster. The temperature scale is reproduced as in the original.
