ZYD-II Double stages vacuum transformer oil purification machine 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 designed with “T” type oil evaporation vessel and auto defoaming system., ZYD-II be more faster and more thoroughly for dewatering, degassing, removing effects of acids and the other. ZYD-II-M is installed enclosed doors and trailers on the basis of the original vacuum oil purifier , and equipped with shock absorption, spring steel plate, with brakes, turn signal light, etc. it is safe and reliable in process of driving. It can move long distance working in field, it can be used indoor and outdoor. ZYD-II-M is professionally designed for purifying electrical insulating oil (transformer oil, switch oil, mutual oil, cable oil, capacitor oil) in the oil-filled electrical equipment, it is moveable with mobile trailer and water-proof doors. Through degasification, dehydration, filtration processes, the machine can remove the dissolved gases ((acetylene, hydrogen, methane etc.) and moisture, solid particulate and contamination completely, it effectively to improve oil’s dielectric strength and to make sure the electric device running safely and stable. Meanwhile, the machine can be used as vacuum oil injecting and vacuum drying equipment for transformers; Especially for the 110KV-500KV large-scale transformer station, ZYD-II-M oil filtration machine is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. And it can be used for filtration live line work onsite. Vacuum purification online work, unattended operation. It is widely used in factory workshops, power transmission, transformer station and generation station Function: a. Removing the moisture. The final treated oil can achieve less than 3ppm,achieve ASTM D1533. b. Degassing. The final treated oil can achieve less than 0.1%; c. Removing particles. The final treated oil can achieve NAS2 Grade (Cleanliness Grade). d. Vacuum oil injecting e. Vacuum drying equipment for transformers  Features: a. Special designed T shape evaporation chamber, the two evaporation chambers make larger space for degassing and dehydration, therefore the maximum utilization of degassing chamber space. b. The world's first oil purifier manufacture adopt with auto- pressurization defoaming technology, more than 200 hours of continuous operation without bubbles rise c. Two vacuum systems: vacuum pump system and roots pump vacuum system, making ultimate vacuum value ≤ 5Pa; working vacuum ≤ 35Pa. d. Adopt “upside down” flash distillation technique; increasing separating time and evaporation surface, thus dewatering and degassing quickly and completely. e. Two vacuum separating chambers, double-horizontal film evaporation technology, can rapidly and effectively separate water, dissolved moisture, gas from oil. f. Adopt “gradual serried filter fineness” technique, the fine filter with accuracy to 1µm; the interception rate of the solid particles is 99.9%. g. Double-infrared liquid automatic sensor, double-infrared liquid automatic controller to ensure the machine working safely. h. Adopt interlocked protective system which connects oil pump, heater and liquid level sensor, thus avoiding blank heating, blank pumping, oil leak and electricity leak. i. Adopt short-circuit, Over voltage, Low voltage, Low battery voltage, Surge protection, loss phase protection. j. “High density “heating system, thus less power consumption, heating uniformity, heating load is less than 1w/cm2. k. Working both online and offline. l. Multi-function machine: oil filtration, vacuum drying and vacuum oil injecting.
