Choosing the right power rating for a transformer oil filter machine depends on several factors, including the oil volume, processing speed, and transformer capacity. Below are the key considerations:
1. Capacity & Flow Rate
- The power of the machine is directly related to its flow rate (measured in liters per hour or LPH).
- Small transformers (≤ 1MVA): 600–1200 LPH
- Medium transformers (1–10 MVA): 1800–3000 LPH
- Large transformers (10–100 MVA): 4000–10,000 LPH
- Extra-large transformers (>100 MVA): 10,000+ LPH
2. Heating Power (kW)
- Transformer oil needs to be heated for effective purification.
- Small systems: 5–15 kW
- Medium systems: 15–40 kW
- Large systems: 40–100 kW
3. Vacuum Pump Power
- A high vacuum system is crucial for degassing and dehumidification.
- Vacuum pump capacity depends on the flow rate and system size.
- Smaller units: ~2–5 kW
- Larger units: 5–15 kW
4. Working Environment
- Consider power supply compatibility:
- Single-phase (220V) for small systems
- Three-phase (380V/415V/440V) for industrial use
5. Additional Features
- Two-stage vacuum for ultra-purification.
- Regeneration system for acidity and sludge removal.
- Online operation for continuous filtration without shutting down the transformer.
Final Selection Guide:
| Transformer Size | Flow Rate (LPH) | Heating Power (kW) | Total Power (Approx.) |
|---|
| <1 MVA | 600–1200 | 5–10 | 6–15 kW |
| 1–10 MVA | 1800–3000 | 15–30 | 20–40 kW |
| 10–100 MVA | 4000–10,000 | 40–80 | 50–100 kW |
| >100 MVA | 10,000+ | 80+ | 100+ kW |
