ZYD-II is our newest research and development of products of ZYD series of high vacuum double stages vacuum transformer oil purifier. ZANYO design the ZYD-II machine is on the basis of ZYD-I old type of transformer oil purifier, comparing with ZYD-I, ZYD-II be more faster and more thoroughly for dewatering, degassing, removing effects of acids and the other.
ZYD-II is mainly applied in power plant, power station, transformer factory, electric power company, power transformation, metallurgy, petrifaction, machinery, traffic, railway and so on, especially for the big distribution equipments, main power transformation gird, large-scale transformer station, which is 110KV-750KV.
- Removing Moisture. The final treated oil can achieve less than 3ppm
- Degassing. The final treated oil can achieve less than 0.1%
- Removing Particles. The final treated oil can achieve1 micrometer
- vacuum oil injecting
- vacuum drying equipment for transformers
- Vacuum purification online work, unattended operation.
Under vacuum and negative pressure state, the water can be vaporized in low temperature, the higher vacuum state; the lower of water boiling point, the water is vaporized faster. Even under same temperature, water can be moved faster under vacuum state. Oil goes into heater after purified by primary filter, Oil temperature goes up when heated. Then oil goes in to vacuum separator to become oil film by the film sprayer. In vacuum separator, water becomes vapor, and discharged by vacuum.
- Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa
- Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies, solid particle interception rate can achieve 99.99%, Cleanliness can achieve NAS 2 Grade.
- Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
- Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
- Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak.
- Condensation before vacuum pump to prolong the vacuum pump and vacuum pump oil.
- Double-infrared level sensor to keep inlet and outlet oil balance
- Adopt with auto- pressurization defoaming technology, to prevent oil escape from vacuum pump
- Low oil level sensor to prevent oil pump idle working, so prolong oil pump lifetime
- Completely Intelligent pressure protector to protect oil pump and fine filter
- Completely Intelligent vacuum controller to protect the booster pump
- Fully intelligent temperature controller to prevent the large surge current
- Double vacuum separators, quickly speed in removing gas and water
- Functions of live line work onsite, vacuum drying and vacuum oiling.
