Dissolved gasses,water, particles and other harmful ingredients in transformer oil can cause arcing, corona discharges,and overheating reducing the electrical efficiency and lifetime of the transformer.And it is dangerous for daily maintenance.Likewise,water contamination at levels as low as 30 ppm (parts per million) can adversely affect the insulating strength of the oil.With ever-increasing standards for energy efficiency of power distribution transformers,the need to effectively degas will become even more important in the future.particles contamination will also affect the function of insulating oil.So we need to clean used transformer oil.and cut down oil expenses.
Specifications:
To remove moisture, gas and particles in transformer oil, mutual inductor oil, switch oil and so on. and restore property of insulating oil, that is suitable for high voltage project 110KV-500KV.
Â
Transformer Oil Indexes After-treatment:
Water Removal: Overall Water Content ≤3 PPM by removing free, emulsified, and dissolved water.
Particulate Removal: Particle counts as low as 1 micron , and more better
Gas Removal ≤ 0.1%
Acid Removal: can be equipped with fullers earth towers to neutralize acid and Lower TAN to <Â 0.03 KOH/g
Dielectric Strength:≥70 kV per ASTM 877

Application:
ZYD double stages vacuum transformer 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 oil's 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 80ºC. Also the impurity will affect oil dielectric strength, so the vacuum oil purifier requires high filtration precision.Â
Features:
1. Pre-Electromagnetic-valve before vacuum pump to prevent the vacuum oil flow backwards.
2. Double-stage vacuum system, strong power of vacuum evacuating, ultimate vacuum value ≤ 5Pa
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.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.
6. Pre-gas-water separator before vacuum pump to prolong the vacuum pump and vacuum pump oil.
7. Double protecting system, Gas-water separator equips liquid level protector to prevent oil escape from vacuum pump
8. Optical oil foam detector and high oil level detector to prevent oil escape from vacuum pump
9. Low oil level sensor to prevent oil pump idle working, so prolong oil pump lifetime
10. Completely Intelligent pressure protector to protect oil pump and fine filter
11. Completely Intelligent vacuum controller to protect the booster pump
12. Fully intelligent temperature controller to prevent the large surge current
13. Phases protector, voltage overload protector to achieve unattended
Advantages:
Comparing with single stage transformer oil purifier, Series ZYD oil purifier can increase the effectiveness more than three times, more quickly and completely dewater, degas, remove particles to get higher dielectric strength. This equipment can be used as independent vacuum source with the functions of vacuum drying and vacuum oiling for the electric plants.Â

Die-casting molds are a method of casting liquid forging, a process performed on a dedicated die-casting forging machine. Its basic technological process is: Molten metal is first filled into the mold cavity at a low speed or high speed. The mold has a movable cavity surface. It pressurizes forging with the cooling process of the molten metal, which eliminates shrinkage shrinkage of the blank. Loose defects also make the internal structure of the blank reach the forged broken grains. The overall mechanical properties of the blank have been significantly improved.
Designing Process
1. according to the product used in the type of materials, product shape and accuracy of the indicators such as the process analysis, set out the process.
2. Determine the position of the product placed in the mold cavity, analyze and design the parting surface, overflow system, and pouring system.
3. Design core assembly and fixing methods for each activity.
4. pull core distance and force design.
5. the design of the ejection mechanism.
6. determine the die casting machine, the mold frame and cooling system design.
7. Check the relative dimensions of the die and the die casting machine, draw the die and the artwork of each component.
8. the design is completed.
