ВШ high-pressure compressor
A high-pressure compressor — working measurements run up to 200 atm. The oil sump holds 17 l; the cylinder-piston group is lubricated through the lubricator.
ВШ-type air compressor, 17 l oil sump: treatment through the crankcase and the lubricator
The class norm is 1.5 ml per litre; for this machine 1.2 ml/l has been assigned for both channels. Piston compressors →
What is treated
- A serviceable compressor with no parts at 100 % wear and no mechanical damage.
- Oil leaks have been eliminated, filter elements washed or replaced.
- The treatment is carried out in place, without disassembling the compressor.
What is measured before and after
| Parameter | Instrument | How and when |
|---|---|---|
| Output — time to fill the receiver from 0 to 100 atm and from 50 to 200 atm | stopwatch, calibrated pressure gauge | — |
| Instantaneous power and current on each phase at idle and under load | clamp meter, wattmeter | The average total power may be taken over 500 or 1000 hours of operation before and after. |
| Actual oil consumption through the lubricator | measuring vessel | — |
| Oil pressure from the oil pump | standard calibrated pressure gauge | At a fixed oil temperature. |
| Vibration level at fixed points of the frame | vibrometer | Preferably at the main bearings of the crankshaft. |
Dosage rates
| Compound | Rate | How and when |
|---|---|---|
| Gel for compressors and bearings — crankcase | 1.2 ml per 1 litre of standard oil per stage | 17 l sump: 20.4 ml per stage, 61.2 ml for three stages (7 tubes of 9 ml). |
| The same gel — lubricator | 1.2 ml per 1 litre of lubricator oil | Over 200 hours. At a consumption of 0.15 l/h — 30 l of oil and 36 ml of gel (4 tubes). |
Treatment stages
- In a separate vessel dilute the gel in standard oil heated to 50–60 °C (1 part gel to 5–10 parts oil), stir until fully dissolved and introduce into the crankcase of the warmed-up compressor.Start of total running-hours count
- The second stage is performed in the same way as the first.After 8 hours of total running time
- The third stage is performed in the same way as the first.After a further 8 hours of running time
After treatment
- Treatment through the crankcase is complete after 450 hours of running time.
- The measurements are repeated in full and compared with the baseline ones.
Points to watch
- Cylinder-piston groups with graphite and flubon (antifriction polymer composite materials) piston rings are not to be treated.
- New compressors — 2 stages through the crankcase and 70 hours through the lubricator.
- Once the mixture has been used up, ordinary standard oil is topped up into the lubricator.
