Oil Press-Which style of oil filter has a good oil filtering effect?

September 27, 2021

Recently, many customers have inquired about which oil filter equipped with the oil press has a good filtering effect. Let's first understand the working principle of the three types of oil filter and then analyze.

 oil filter

       1. Working principle of plate and frame oil filter:


       The filter cloth is lined between the filter plate and the filter frame as the filter medium, and the filter plate and the filter frame are placed between the fixed thrust plate and the movable plate by the pressure of the pressing device, thereby forming a separate filter The chamber, the filter cloth that is compressed between the filter plate and the filter frame, the filter plate and the filter frame are provided with two through-liquid holes at the corresponding positions. When compressed, they form two complete channels, and the ears are triangular. Dirty oil is introduced on one side, filtered through the filter chamber, and clean oil is drawn from the other corresponding channel (on the side where the ears are fan-shaped). Note: The filter cloth of the plate-and-frame oil filter matched with the oil press can be reused after disassembly, which saves resources.


        2. Working principle of vacuum oil filter:


       The vacuum pump draws out the air in the vacuum tank to form a vacuum, and the external oil liquid removes larger particles under the action of atmospheric pressure. The filtering speed is fast when the oil temperature is high. The heated oil is separated into a semi-mist through the rapid rotation of the spray wing, and the water in the oil evaporates rapidly into water vapor and is continuously sucked into the condenser by the vacuum pump. The water vapor entering the condenser is cooled and then returned to the original water to be released. The oil in the vacuum heating tank is discharged into the fine filter by the oil drain pump, and the particulate impurities are filtered out through the oil filter paper or filter element, so as to achieve oil-water separation and impurity separation. Effect.


       3. Working principle of centrifugal oil filter:


      In the high-speed rotating oil filter, the multi-components with different densities form a ring under the action of centrifugal force. The solid particles with the highest density move outward and accumulate on the peripheral wall of the drum, and the light phase liquid is in the innermost layer. Because the centrifugal force generated by the high-speed rotation of the drum is far greater than gravity, centrifugal separation only takes a short time to obtain the effect of gravity separation, especially when gravity separation cannot be achieved, only the method of centrifugal separation can be used. A simple understanding, it is equivalent to the part of the double tub washing machine in the home. When the washing machine is running, it will throw out the moisture in the clothes. In the centrifugal oil filter, only the clothes are changed to oil.


       The above are the working principles and characteristics of the three oil filter units. You can choose according to your own requirements.
