Vacuum dehydration system for terminated oil purification
The primary function of vacuum dehydration and purification is to remove free, emulsified, and dissolved water from oil, as well as solid particulate contamination. The secondary function of the system is the extraction of air, gases, and light hydrocarbon contamination from the oil. These functions are accomplished using the principles of low temperature vacuum distillation and micronic filtration.
Vacuum Dehydration - Many are aware that vacuum dehydration will remove free, emulsified and dissolved water from their lubricants. In many cases, high quality vacuum dehydration units can achieve overall water content as low as 20 parts per million. However, vacuum dehydrators also serve other functions. High quality vacuum dehydrators are equipped with high efficiency filters that can achieve particle counts as low as ISO 14/12/9. In addition, refrigerants, solvents and fuels are removed by vacuum dehydration.
In order to achieve optimal dielectric strength and insulating performance inside of transformers and circuit breakers, dielectric oils must be kept absolutely clean and dry. ZHONGNENG designs and builds the most effective, durable, and easily operation high vacuum transformer oil purification system on the market today. Transformer oil treatment plant means?Old transformer oil is generally mixed with gas, water and contaminants, and also the new transformer oil sometimes, the content of the contaminants generally increases fast by time. So the transformer oil treatment machines can remove these associated gases, water and contaminants, and separate them from the oil and take them away. After treating the oil by our oil treatment plant, the stabilized oil is then again ready to be used in power transformers.
Series ZYD Double-stage transformer oil purifier can quickly remove water, trace water, gas, particles as well as acetylene, hydrogen, methane and other harmful ingredients from oil effectively to improve oil's dielectric strength, effectively making sure electric equipments working safely and normally. Series ZYD oil purifier is particularly suitable for treating high-grade transformer oil, super-voltage transformer oil and new transformer oil. It can be used for filtration of more than 110V substation live line work onsite. Meanwhile, Series ZYD oil purifier can be used as independent vacuum source with functions of vacuum drying and vacuum oiling.
Technology and advantages of this model:
1: It is for treating various insulating oil, including transformer oil, mutual inductor oil, switch oil.
2: It is widely applied in large scale manufacturing factory, power station and other related industrial fields which will use transformers, especially for over 110 KV transformers.
3: Double stage vacuum system, adopt international advanced duplex stereo-evaparation technology and UK G technology to eliminate the trace water in insulation oil and recover its breakdown voltage greatly.
4: Adopt Germany's 3 UG phase replay, can make the machine working efficaciously and safely at any situations, such as power off, lack of phase, wrong phase position, etc.
5: Equipped with advanced dielectric condensation devices for greatly prolong the oil purifier service life.
6: A trinity of interlocked preventive device is applied for avoid the machine being damanged from any accident automatically.
7: It also can be used as a separate vacuum system for dehydrating oil only, don't need to run all process and can save time and consumption for different request on oil filtration.
8: It can work onsite with the transformer running together.
9: A PLC system can be attached as per customer's requirement.
10: It can be moved easily with equipped steel wheels, it also can be designed for different structure of fully enclosed type and fully enclosed trailer type for the purpose of ourdoor use and indoor use.
11. Various color of this model can be produced just as customer's favor.
The oil technical data after treatment:
1. Gas content less than 0.1%
2. Impurity size less than 1μm without free carbon
3. Oil dielectric strength (breakdown voltage) more than 75KV
4. Acidity value less than 0.01 mgKOH/g
5. Dielectric loss factors at 90℃ less than 0.001

Where can I find a DC power supply that puts out at least 65 amps @ 12 volts, or at least 32.5A @ 12V?
I'm looking for a DC power supply that plugs into a regular 110V wall outlet, and puts out at least 65A @ 12V, 90A max, or at least 32.5A @ 24V (not sure what the max amperage would need to be for 24V). It's to power a hydraulic wheelchair lift that's installed in my house. So far I've been using a car battery, but I'm tired of taking it outside to charge every few days. I got the specs from the manual, and I said 90A max because the local technician installs 90A circuit breakers on his when He installs in a wheelchair van.
So far I've had no luck with google, or ebay.
Getting a 120v motor...that's an interesting suggestion. Any chance I could just swap out the motor, without having to do any other modifications?
I don't know what kind of motor drives the hydraulic pump, but apparently it is 12 dc. Why not look into getting a 120 volt ac motor and eliminate the 12 volt problem altogether. I am sure it will be cheaper ( and safer ) than adding more equipment.
Check with a local W.W. Grainger and they might have a motor for you.
Best of luck

I don't know what you unit looks like and how it connected to the unit. When I was doing television repair years ago, there was a hydraulic repair shop next door. I help them occasionally with electrical problems they encountered so I seen many units. When I left TV repair, I went to work for Grainger ( I have since left there as well ). So I seen much of this type of equipment. If your motor is coupled to the pump via a jaw coupling hub of some type, you might be in luck. Then the other thing you will need to do is figure out what type of motor mount and specs are for your motor and swap it out. Hopefully a good service counter guy at Grainger will help you out with that. I know this sounds like a lot to do, but in the long run you will so much better off.
Now if the motor and pump at built together ( and that could very well be the case with a 12 volt system ), then you have to do something else. The only other things I can think of that will give you the amps is a car battery charger. I know mine has 3 settings on it. 2 amp, 10 amps and 50 amps for starting. so maybe that can help you out.
I am sorry I can't be more helpful, but I been in a different field of work altogether and rarely even think about these things anymore unless it is for personal use.
