  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.
  In view of customers’ special requirement, we have also developed DYJ-B series of semi-automatic lubricating oil purifier, DYJ-Q automatic multi-function lubricating oil purifier and DYJ-Ex anti-explosion multi-function lubricating oil purifier. It is suitable to work in different conditions.

Application scope:
  It is widely used in metallurgy, machinery, oil field, chemistry, mine, electric power generation plant, transportation and manufacturing enterprises for hydraulic oil, gear oil, engine oil, compression oil, freezer oil, heat treatment oil, etc. It can remove water, gas and mechanical impurities, light acid and light hydrocarbon from oil, and improve oil quality, resume its lubricating property and ensure normal operation of the equipment.

Characteristics:
1. Super ability in breaking emulsion, dehydration and degassing process. Adopting big-cubage, reinforced three-dimension flash distillation column, thin film evaporation technique and large area multi-level separation technique so as to remove water, gas and light hydrocarbon material efficiently and quickly.
2. Adopting high-quality filter element and sealing material with corrosion proof, high temperature resistance and excellent mechanical strength, it is suitable even for purification process of high-viscosity oil under rather high temperature conditions and in this way expanding its application scope.
3. Fine and precision multi-stage filtration system can remove mechanical particulates thoroughly and effectively.
4. With air-cooling and condensation system, it can cool the air in the vacuum system efficiently and quickly, which avoids inconvenience of water-cooling.
5. Advanced high pressure protection device and infrared oil level control system for easy operation.
6. Perfect automatic and manual oil heating temperature controller, automatic cooling and separation device, simple, safe and reliable.
7. Aluminum electrical control cabinet, with high efficiency for heat transfer and anti-explosion.
8. The equipment can also be installed with digital flow meter and timer for auto calculating and recording oil volume and working time. (it’s optional according to user’s requirement)
9. The machine can be installed with two filtration systems for easy and quick change of filter element without stopping the machine.
10. Besides all these mentioned above, this series of oil purifier also has the following merits:
 (1) Automatic oil purifier series is installed with PLC (programmable logical computer system), which can control the equipment automatically to every stage of its process and ensure its safe operation on site and on line without human supervision.
 (2) The equipment is installed with auto alarming system, it will give out alarm and stop the whole machine when electrical motor is overloaded, vacuum pump and oil pump overloaded, heater overloaded and pressure abnormal.
 (3) The equipment is installed with auto control of vacuum pressure, auto drainage of water from the equipment.
