Pressure Filter Oil Machine Is a Vacuum Oil Purifier
Plate and frame pressure filter oil machine is an ideal equipment for pre-filtration before vacuum oil purifier and turbine oil purifier. For oils without lubricity such as gasoline, diesel, kerosene, etc., this machine consists of filter bed, oil pump, motor, and coarse filter. Between the filter plates and frames, filter paper or cloth is used as the filtering medium. The filter plates and frames are fixed by the pressure of manual screw pressing device to form a separate filtering chamber, and the filter paper or cloth pressed between them plays the filtering role. It has the advantages of simple structure, convenient and quick filter paper replacement, easy operation, and low operating cost.
Working Principle
During filtration, dirty oil is distributed into each filter frame through the input channel, and impurities are filtered onto the filter plates through the filter element, then collected in the output channel, and discharged out of the machine. The dirt remains on the surface of the filter paper, and small water droplets in the emulsified oil are absorbed by the capillary of the filter paper, forming large water droplets that flow to the bottom of the filter bed and are discharged from the drain valve at any time. When the filter residue on the surface of the filter paper gradually thickens and the moisture content in the filter paper increases, the filtration resistance increases. When it increases to a certain extent (generally 0.3-0.5 MPa), filtration should be stopped, and after replacing the filter paper, continue to use.
Technical Features
1. It consists of filter bed, oil pump, and coarse filter. This machine uses filter paper or cloth as the filtering material, which is somewhat similar to a water filter.
2. Between the filter plates and frames, filter paper or cloth is used as the medium, and replacement is convenient. The filter plates and frames are fixed by the pressure of the pressing device to form a separate filtering chamber, and the filter paper or cloth pressed between them plays the filtering role.
