Series ZYD Double-stage vacuum transformer oil filter / oil purifier
Application:
ZYD double stages vacuum transformer oil oil filter / oil purifier is mainly used for removing trace water, gas and impurities from insulating oil, improving the insulating oil performance index. It is mainly applied to purification of 110KV, 220KV, 500KV, 750KV, 1000KV power transmission equipment insulating oil, also applied to treat low viscosity oils, like insulating oil, turbine oil, and hydraulic oil in the transmission equipment which is lower than 110KV.
Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling. Insulating oil performance mainly decided by oils water content, If the water is not saturation in the oil, it appears as the molecular states; If water is saturation in the oil, it appears as the liquid states and stay at the bottom of container. Under the vacuum states, because the less gas content, the water and gas in the oil will be escaped from the oil and evacuated by the vacuum pump. The higher vacuum value (Close to 0 Pa), the higher speed of water molecular volatilization (The latest technology, the Vacuum oil purifier can reach to 1Pa Working vacuum value). The gas and water which dissolved in the oil will become gaseity and exhausted by vacuum pump. The oil temperature affect vacuum oil purifier working efficiency, the higher temperature, the water molecular get more kinetic energy, so it is higher diffused speed of water molecular. But, exorbitant temperature will cause fracture of carbon chain for oil molecular, if that will make oil bad. So we don't suggest the oil temperature excess 80C. Also the impurity will affect oil dielectric strength, so the vacuum oil purifier requires high filtration precision.
Features1. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa
2. Two vacuum separating chambers, efficient oil film sprayer, increasing separating size and separating time to ensure the dry-level and dielectric strength improving greatly.
3. Double-horizontal film evaporation technology, combined with unique and advanced dewatering, degassing components, can rapidly and effectively separate water, gas from oil.
4. Multi-stage precision filtration system, mesh filtration combined with molecular adsorption technologies
5. Efficient electric heating system, heating uniformity, less power consumption, safe, and reliable.
6. Double-infrared liquid level sensor, pressure protective system to ensure machine operation easy and safely.
7. 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.
8. Functions of live line work onsite, vacuum drying and vacuum oiling.| Index name | unit | ZYD-30 | ZYD-50 | ZYD-100 | ZYD-150 | ZYD-200 | ZYD-250 | ZYD-300 |
