 Oil purifier makes oil lubrication system more smoothly




Why do we choose oil purifier?

After a period of operation, owing to its own oxidation and contamination with foreign materials, or due to improper transportation or storage, the oil will lose its original property and cannot be used effectively again. So Wanmei provides high efficiency vacuum oil purifiers, which can efficiently remove free and dissolved water, dirt, gases and other foreign impurities from oil, such as de-electrical oil, turbine oil, lubricating oil, engine oil, hydraulic oil, compression oil, mechanical oil, quenching oil, heat conducting, gear oil etc; so as to maintain its lubricating and insulating property, at the same time greatly reduce components wear, and cut down maintenance and oil replacement expenses.



General Description:
DYJ series oil purifier is a kind of multi-function equipment for dehydration, degassing, and purification process of lubricating oil. It is developed and produced by Wanmei company to deal with different kinds of lubricating oils of various types of kinematical viscosity and flash point. It is ideal equipment for factories, mines, and other enterprises to purify different kinds of lubricating oils. The double-stage and multi-stage oil purifier are more efficient in their operation.




1. Super ability in breaking emulsion, dehydration and degassing process, Germany three-dimension flash distillation technique, American coalescence and separation technique, Italian thin film evaporation and large area multi-level separation technique and Russian spraying technique.


2. Precise multi stage filtration system for metal and mechanical particulates. Filter element and sealing material with corrosion proof, high temperature resistance and excellent mechanical strength, it is suitable for high-viscosity oil under rather high temperature conditions.


3. Safe and reliable electrical heating system. The electrical heater is installed with vortex tube heating element to keep the temperature even and constant, quick heating, inter cycling, auto overload protection.


4. Advanced auto control system. The equipment is installed with high pressure protection device, float and infrared oil level controller and auto de-foaming system.


5. Efficient air-cooling and condensation system. Steam is condensed into water and leads to the water drainage tank. Air and gases is let out to atmosphere.


6. Reliable quality for efficient operation. Major parts of the equipment are of first class quality in the world. Electrical control apparatus are imported from Schneider France. Aluminum electrical control cabinet is of high efficiency for heat transfer and anti-explosion.


7. Light and sound alarm system.


8. Automatic oil purifier series is installed with PLC (programmable logical computer system).


9. Optional parts. The equipment can also be installed with digital flow meter and timer for auto calculating and recording oil volume and working time.


Advantages of our machine:


* Magnetic separation technique to remove metallic particulates


* Coalescence separation technique to remove free water


* Vacuum distillation technique to break emulsion and remove water and light hydro carbon material


* Aerification separation technique to remove air and gases


* Pressure filtration technique to remove solid particulates


* Liquid film fine filtration technique to remove micro impurities


* Absorbing technique to remove acid, alkali and colloidal materials

Process Description:

The oil is sucked by vacuum into the oil purifier and firstly comes into an electrical heater to a range of adjustable temperature from 40 -- 60°C. Secondly the oil passes through a magnetic coarse filter to get rid of bigger grains of solid particulates. It then comes into a coalescence and separation filter to get rid of moisture. The filter element is made of oil oriented material and only oil can easily get through the filter while the free and dissolved water is condensed and separated on the surface of the element and finally drained out from the bottom of the filter. Then the oil is led to a flash distillation column, where the oil is sprayed and forms into thin film of 0.025mm. In the course of its going down to the bottom of the column, the oil is thoroughly de-emulsified, dehydrated and degasified under vacuum condition in the column. The steam is condensed and drained out, hydrocarbon and gasses are led out by the vacuum pump to the atmosphere. The treated oil is led out after going through another fine filter for further precise filtration.






A. check and adjust after oil purifier works for a period of time
    1. all the electric control apparatus 
    2. temperature controller
    3. oil seals and motor couplings 
    4. clean filter elements, check pumps and motors
    5. all the pipes for leaking
B. Clean the motor and change the lubricating grease
C. Check and add specified lubricating oil to vacuum pump,
D. If oil purifier is not in use for one month or more, put it on a dry, flat ground, close all valves and electric cabinet, cove the whole machine with canvas.


The result of purified oil and before.
