4New RO Series Vacuum Oil Filter

Short Description:

It is used to purify hydraulic oil, mechanical oil, cooling oil, refrigerator oil, gear oil, turbine oil, diesel oil and other wheel lubricating oil. It can quickly remove water, impurities, volatile substances (such as ammonia) and other harmful components from the oil, improve the quality of the oil and restore its service performance.

Product Detail

Application introduction

1.1.  4New has more than 30 years of industry experience, and its R&D and manufacturing of RO series vacuum oil filter is mainly applicable to the ultra-fine purification of lubricating oil, hydraulic oil, vacuum pump oil, air compressor oil, machinery industry oil, refrigeration oil, extrusion oil, gear oil and other oil products in petroleum, chemical, mining, metallurgy, power, transportation, machinery manufacturing, railway and other industries

1.2.  RO series vacuum oil filter adopts low temperature vacuum negative pressure and adsorption principle to remove impurities, moisture, gas and other harmful substances in the oil, so that the oil can restore its service performance, ensure the proper lubrication effect of the oil and extend its service life.

1.3.  RO series vacuum oil filter can prolong the service life of equipment components, reduce unplanned downtime and maintenance time, and improve production efficiency. At the same time, the waste liquid treatment cost is reduced, and the resource recycling is realized.

1.4.  RO series vacuum oil filter is especially suitable for harsh working conditions with high oil-water mixing degree and high slag content, and the processing capacity can reach 15~100L/min.

Product advantages

1.1.  The combination of coalescence and separation and vacuum compound three-dimensional flash evaporation makes dehydration and degassing faster.

1.2.  The combination of multi-layer stainless steel mesh filtration with imported materials and composite polymer adsorption materials can not only make the filter element β3 ≥ 200, and can make the oil clear and transparent, and can be reused.

1.3.  Safe and reliable, with quadruple protection: pressure control protection, temperature control protection, temperature limit protection, flow switch protection. Humanized interlocking protection and automatic PLC system realize unattended online operation.

1.4.  Compact structure, less land occupation and convenient movement.

Technological Process


Working mode

1.1.    Equipment composition

1.1.1.   It is composed of coarse filter, bag filter, oil-water separation tank, vacuum separation tank, condensation system and fine filter. The container is made of 304 stainless steel.

1.1.2.   Coarse filtration+bag filtration: intercept large impurity particles.

1.1.3.   Oil-water separation tank: separate the stratified cutting fluid and oil once, and let the oil enter the next step of treatment.

1.1.4.   Vacuum separation tank: effectively remove water in oil.

1.1.5.   Condensation system: collect the separated water.

1.1.6.   Fine filtration: filter the impurities in the oil to make the oil clean and reusable

1.2.    Working principle

1.2.1.   It is designed according to the different boiling points of water and oil. It is composed of vacuum heating tank, fine filter tank, condenser, primary filter, water tank, vacuum pump, drain pump and electrical cabinet.

1.2.2.   The vacuum pump draws the air in the vacuum tank to form a vacuum. Under the action of atmospheric pressure, the external oil enters the primary filter through the inlet pipe to remove large particles, and then enters the heating tank.

1.2.3.   After heating the oil at 45~85 ℃, it passes through the automatic oil float valve, which automatically controls the balance of the amount of oil entering the vacuum tank. After heating, the oil will be separated into semi-mist through the rapid rotation of the spray wing, and the water in the oil will rapidly evaporate into water vapor, which will be continuously sucked into the condenser by the vacuum pump.

1.2.4.   The water vapor entering the condenser is cooled and then reduced to water for discharge. The oil in the vacuum heating tank is discharged into the fine filter by the oil drain pump and filtered out by the oil filter paper or filter element.

1.2.5.   During the whole process, impurities, water and gas in the oil can be removed quickly, so that the clean oil can be discharged from the oil outlet.

1.2.6.   The heating system and filtration system are independent of each other. Dehydration, impurity removal or both can be selected as required.
