1. ZYD-W Transformer Oil Purification Plant
The necessity for transformer oil treatment, dehydration and degassing is well known for a long time. Transformer oil is used in power equipment where it provides cooling and insulation protection. Over time aggregated moisture, gasses and solid particles can seriously affect these properties. To remove moisture, gasses, and solid particles, vacuum transformer oil dehydration and filtration plant needs to be used.
Series ZYD-W Fully Enclosed type transformer oil filtering, degassing and drying machine is designed by FUOOTECH® mainly for the power station, industrial and mining enterprises purifying the unqualified transformer oil, mutual inductor oil, switch oil and so on.
This oil purifier machine is made in fully enclosed type at outdoors usage for weather proof, sand proof, wind proof. All the components such as pumps, motors, filters, tanks, valves, pipelines, controls, etc… are totally enclosed and protected by steel frame cover and heavy duty metallic doors and designed for lifting crane (equipped with lifting hooks). The equipment inside will be facilitated by a system of door locks installed at a perimeter of the enclosure.
2. Description
Oil is heated by electrical heaters with surface efficiency below 1.5 W/cm, with indirect heating to prevent local overheating. Oil at the outlet is filtered by a fine, up to, 1-micron filter to filter out solid particles before returning the oil back to the transformer. Equipment is fully automatic, optionally controlled by PLC system with large-size touch screen. Numerous safety features are introduced throughout the plant to ensure the safety of the equipment as well as the operating personal. Aeration valves, overheating protection, and automatic level switches guarantee the safety of the equipment as well as its ability to identify a possible risk and to power down to prevent any accidents.
All vacuum dehydration oil purification systems optionally possess a positive displacement rotary inlet pump. We choose the high quality screw type oil pumps to control the oil entering and discharging. For dehydration and degassing, a rotary vane vacuum pump and a mechanical booster roots pump are used. Vacuum chamber houses a variable amount of evaporation elements to achieve most efficient treatment of oil.
