Vacuum Oil Filling Machine

Description This vacuum oil filling machine is used to fill the transformer oil in vacuum condition (drying function can be added according to client’s requirement). Vacuum oil filler is widely used for amorphous transformers, HV oil immersed transformers, HV bushings and capacitors, etc. The plant can automatically running and quantitative oil filling.
1. Perfect vacuum condition and precision quantitative filling ensure high quality.
2. Maximum adopts three-stage vacuum pump system, limit vacuum up to 1pa(unload), leakage rate <= 0.4mbar/s
3. Oil separator is installed between vacuum tank and pump system, which can condensate and recovery some oil, finally reducing the damage and pollution to the pump system.
4. Rectangle type tank adopts frame type flange to ensure long working life.
5. Vacuum tank has heating function, which is heated by electric through conductive oil. Tank door is heated by electric heating plate. Temperature raising is uniform and reliable, no local over heating.
6. Vacuum oil filling machine is adjustable and automatic control.
7. Heat exchanger is equipped. The vacuum tank temperature can be reduced below 70℃ to reduce moisture regain during discharging.
8. All oil filling pipelines and accessories are stainless steel. Flow meter is equipped on main pipeline and each filling pipeline.
9. With PLC system and touch screen, the vacuum oil filler can fully automatic control on the whole process.
10. Impeccable alarm system: All the parameters can be indicated, record and printed.
