Ashton's latest research and development of AXDY series automotive parts industry-specific engine oil dehydration regeneration vacuum oil filter

The AXDY series multifunctional engine oil regeneration vacuum oil filter for the automotive industry is the latest multi-functional vacuum oil filter developed by the Ashton Oil Filter Research Institute for the purification treatment of engine oil, gasoline engine oil, engine oil, diesel engine oil, lubricating oil, etc. in the automotive industry, based on the DY series multifunctional lubricating oil vacuum oil filter. Dongfeng Motor Group Light Engine Company, Guangzhou Automobile Group, Changan Automobile Co., Ltd., Jianghuai Automobile, and others have purchased the Ashton AXDY series of vacuum oil filters for filtering engine oil.

purpose：
Mainly targeting people in the automotive manufacturing industry, the engine oil undergoes deep purification treatment to restore its functional use, with a cleanliness level of up to level 5 and a water content reduced to 50PPM, which can extend its service life by 2-3 years. AXDY Sharp is an upgraded platform of the DY series lubricating oil vacuum filter, which also takes into account the filtration of various lubricating oil specifications and types such as heat treatment oil, air compressor oil, hydraulic oil, hydraulic transmission oil, gear oil, turbine oil, diesel oil, compressor oil, refrigeration oil, etc. If the customer has strict requirements for moisture and impurities, and the moisture content is less than 50PPM, internal circulation treatment is required. If the oil that needs to be filtered is a high viscosity oil, it needs to undergo preliminary heating treatment before it can be filtered. Our company has specialized supporting equipment: swirl heating axe.

Features:

• Efficient three-dimensional vacuum flash evaporation technology, thin film evaporation technology, capable of quickly removing water, gas, light hydrocarbons, organic acids, and inorganic acids from oil.

• The precise multi-stage filtration and step-by-step encryption filtration system has high filtration accuracy, large pollutant holding capacity, and long service life of the filter element.

• The advanced pressure protection system, liquid level control system, and infrared constant temperature device ensure the safe performance of the equipment.

• According to user requirements, this machine can also adopt a filter quick change dual system design, achieving the replacement and cleaning of filter elements without stopping the machine.

Process flowchart:

Working principle of oil filter:
The oil that needs to be filtered enters the heater under the external atmospheric pressure and the suction vacuum of the oil filter by the vacuum pump. The heated oil passes through a strong magnetic filter, filtering out metal particles and large impurities. The oil containing small impurities enters the second and third stage filters for further filtration. The oil with impurities removed enters the three-dimensional vacuum flash tower. Under the action of the spray device, the oil is dispersed into a mist and sprayed onto the three-dimensional flash Bauer ring, forming a very thin oil film. The oil film curve moves downward, and through environmental changes such as cooling and pressure reduction, a series of physical changes are generated, thus carrying out a complete separation process of demulsification, dehydration, and degassing. During the entire process, the mixed gas formed by water vapor, light hydrocarbons, and other gases enters the water gas separation device, strong wind condensation system, and vacuum buffer chamber to rapidly cool the substances such as water vapor and light hydrocarbons. The condensable gas and water vapor condense into water and are discharged through the drainage device, while the non condensable gas is discharged through the vacuum pump. The oil, after removing moisture, gas, and mechanical impurities, enters a precision filter through an oil pump to filter out particles and impurities in the oil, completing the entire oil purification process.
