China Industrial Safety Vacuum Transformer Oil Purifier Oil Centrifuging Machine
DVP Application:
DVP series double stages vacuum transformer oil purifier is special designed for processing insulating oil of high voltage electric equipments(especially for more than 500KV UHV insulating oil) in workshops or the field, storage tanks or drums, it adopts double stages vacuum source, double stages vacuum dehydration and degasification vessels, three stages precise filtration system, which can separate moisture, gas, particles and other harmful ingredients from oil much quickly and effectively to ensure the dry-level and dielectric strength improving greatly. Meanwhile, DVP machine can be used for online oil treatment for transformers and vacuum drying and oil-pumping for electrical equipment. It is also applied to the above 110KV EHV transmission and distribution equipment, capacitor oil, cable oil, mutual inductor oil etc.
About this machine:
This DVP100 model transformer oil purifier machine is horizontal type with PLC system,it design as two horizontal vacuum chambers,can treat 100L/minute(6000L/hour) transformer oil,this machine can be produced with Europe famous brand pumps.such as Germany Leybold ,Kracht,ABB or China famous brand pumps as customer required. This DVP100 automatic type transformer oil purifier machine mostly suitable for power plant, power engineering, the power supply house ,Hydroelectric power station,Wind power station,Coal power station,transformer oil purify service agent etc.
Features:
① Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa.
② Horizontal double vacuum separation technology, doubling the evaporation area and degassing time
③ Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
④ Duplex-Stereo film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
⑤ Automatic double-infrared liquid level controller, pressure protector, which ensure long-term safely and reliable operation.
⑥ Pre Electromagnetic valve before vacuum pump to prevent the vacuum oil flow backwards.
⑦ Automatic defoaming system with dual electronic monitoring system, which avoid the foam ejecting and gushing to vacuum pump.
⑧ Pre gas water separator before vacuum pump to prolong the vacuum pump and vacuum pump oil.
⑨ Adopt interlocked protective system, which connect oil pump, heater and liquid level sensor, avoiding blank heating, blank pumping, oil leak and electricity leak. If there is any fault, machine will be power off automatically.
⑩ Multi-stage precise filtration system with gradually increasing precision, which can effectively remove mechanical impurities from oil.
⑪ Optical oil foam detector and high oil level detector to prevent oil escape from vacuum pump
⑫ Low oil level sensor to prevent oil pump idle working, so prolong oil pump lifetime
⑬ Completely Intelligent pressure protector to protect oil pump and fine filter
