Compressor ВЕ-6/13
Reciprocating compressor with a 20 l oil system. Treatment in three stages through the crankcase, without taking the machine out of service.
ВЕ-6/13 reciprocating air compressor, 20 l oil system
The class norm is 1.5 ml per litre; the same amount is used here, but the top-up oil is dosed at the increased rate of 2.0 ml/l. Piston compressors →
What is treated
- A serviceable compressor with no parts at 100 % wear and no mechanical damage.
- Oil leaks eliminated, filter elements washed or replaced.
- Treatment is carried out in place, without disassembling the compressor.
What is measured before and after
| Parameter | Instrument | How and when |
|---|---|---|
| Output — filling time of a separate receiver | stopwatch, calibrated pressure gauge | From the same initial pressure to the same final pressure, with the shut-off valves in good order. |
| Power consumption or current at no load and under load | clamp meter, wattmeter | Phase by phase. The standard pointer instruments are unsuitable — they lack sensitivity. |
| Oil pressure at a fixed operating temperature | standard calibrated pressure gauge | — |
| Vibration level at fixed points on the frame | vibration meter | The points are at the crankshaft main bearings. |
| Air temperature at the outlet of each stage | thermometer | At the same ambient temperature. |
Dosage rates
| Compound | Rate | How and when |
|---|---|---|
| Gel for compressors and bearings | 1.5 ml per 1 litre of the standard oil per stage | 20 l system: 90 ml for the full cycle (10 tubes of 9 ml, 3 + 3 + 4). |
| The same gel — top-up compensation | 2.0 ml per 1 litre of added oil | For the first 200 hours, so that the concentration does not fall. |
Treatment stages
- In a separate vessel, dilute the gel in the 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 the cumulative operating-time count
- The second stage is the same as the first.After 8–12 hours of cumulative operating time
- The third stage is the same as the first.After a further 8–12 hours of operating time
After treatment
- The treatment is complete after 450 hours of cumulative operating time.
- The lubrication system temperature may be measured with a non-contact infrared thermometer.
Points to watch
- Treatment of the cylinder-piston group with non-metallic piston rings is not recommended.
- New compressors, or those with wear up to 10 % — 2 stages.
- If oil consumption is elevated, for the first 200 hours top up the oil with gel at 2.0 ml per litre of top-up oil.
