Compressor АДП-720/2,5
Treatment is carried out through the crankcase only: the lubricator is not used, and no second compound is prepared.
Compressor АДП-720/2,5: treatment through the crankcase oil bath
The class standard is 1.5 ml per litre; for this machine 1.2 ml/l has been assigned. Piston compressors →
What is treated
- A serviceable compressor with no parts at 100 % wear and no mechanical damage.
- Oil leaks eliminated, filter elements flushed or replaced.
- Treatment is performed 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 the sensitivity. |
| Oil pressure at a fixed operating temperature | standard calibrated pressure gauge | — |
| Vibration level at fixed points of the frame | vibrometer | The points are at the main bearings of the crankshaft. |
| 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 | 1.2 ml per 1 litre of standard oil per stage | The carrier oil is heated to 60 °C, in a proportion of 1 part gel to 5–10 parts oil. |
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 completely dissolved and introduce into the crankcase of the warmed-up compressor.Start of the total operating time count
- The second stage is the same as the first.After 8 hours of total operating time
- The third stage is the same as the first.After a further 8 hours of operating time
After treatment
- The treatment is complete after 400 hours of total operating time.
- The measurements are repeated in full and compared with the initial ones.
Points to watch
- Carry out the treatment on the standard oil without significant contamination.
- Before starting, flush or replace the filter elements of the lubrication system.
