The working principle of three types of oil filter machine

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 liquid holes at the corresponding positions. Dirty oil is introduced on one side, filtered by the filter chamber, and clean oil is drawn from the other corresponding channel (on the side of the ears in the shape of a fan). Note: The filter cloth of the plate-and-frame oil filter supporting the oil press can be reused after being removed and washed to save 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 wings, and the water in the oil evaporates rapidly into water vapor and is continuously sucked into the condenser by the vacuum pump.   and the particulate impurities are filtered out through the oil filter paper or filter element 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. , Since the centrifugal force generated by the high-speed rotation of the drum is much greater than gravity, centrifugal separation only takes a few minutes 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 at home. When the washing machine is running, it will throw out the moisture in the clothes. In the centrifugal oil filter, it is just the oil that the clothes are changed into.
