Transformer Evacuation Vacuum Pump for Transformer Maintenance

Features of Transformer Evacuation Vacuum Pump for Transformer Maintenance

1. Quick starting, high pumping rate, stable performance, and easy handling.
2. The unit takes a roots pump as the main pump and a spinning vacuum pump as a pre-stage pump.
3. A vacuum meter is used to meter and control the vacuum of the pumped container.
4. The unit adopts French Schneider Electric as a control element.
5. Full-automatic and non-presence operation with lamps indicating the condition of operation.
6. Humanization design, low noise, less energy expenditure, economical to circulate cost.
7. You have a variety of transformer evacuation systems from YUNENG to choose from.

Notice:

The Transformer Evacuation System for Transformer Maintenance is unsuitable for pumping toxic gas, explosive gas, high-oxygen content gas, high-moisture content gas, and gas which will be a reaction to pump oil or cause an erosive effect on ferrous metal.

Applications of Transformer Evacuation Vacuum Pump for Transformer Maintenance

1. The transformer evacuation vacuum pump is used in vacuum smelting, welding, drying, chemical and pharmaceutical, electric vacuum devices, and other industries such as vacuuming.
2. Maintenance is used to extract the vacuum of the electrical vacuum device in the transformer substation, administration of power supply, power generation plant, and transformer manufacturer, ZJ operates in a vacuum degree of 133Pa, and its limit vacuum degree is 1Pa.
3. It has the characteristics of quick start, high pumping speed, stable performance, and easy operation.
4. It is especially convenient for vacuuming, vacuum oiling, vacuum drying, etc., of transformers or electric equipment.
5. The unit can be equipped with an imported vacuum pump or an imported roots pump as needed.
6. The unit uses a roots pump as the main pump and a rotary vane vacuum pump as the foreline pump.
7. An electromagnetic vacuum inflation valve is connected in series between the foreline pump and the main pump and is opened and closed with the front stage pump switch.
8. An electronic vacuum gauge can be installed at the air inlet of the unit to accurately observe and control the vacuum of the pumped container.
