The function and model of filter separator in hydraulic system Apr 14, 2018

The hydraulic system usually has high requirements for the purity of the hydraulic oil, so the corresponding filter separator is set up in the system to filter the dirt particles, fine particles and the contaminants in the oil, so as to prolong the service life of the equipment and improve the reliability and stability of the system work.

 

In order to achieve the above objectives, the filtration precision of the filter separator in the hydraulic system should meet the sliding clearance needs to be protected. If the filter mechanism is divided according to the filter mechanism, it can be divided into three kinds, such as surface type, depth type and adsorption type.

 

The filtering function of the surface type filter separator is realized by a geometric surface. The filter core material has a uniform calibration hole, which can be used to filter out particles larger than the small hole size. The filtered particles are intercepted on the surface of the filter core on the upper side of the oil liquid, and the mesh filter and the line gap filter are all this type.

 

The filter depth type filter separator by porous permeable material, with twists and turns of the internal channel. Particles larger than the surface diameter are trapped on the outer surface, and smaller particles enter the interior of the material and are adsorbed by the channel wall. Such filters as paper, felt, sintered metal, ceramic and all kinds of fiber products belong to this kind.

 

The remaining adsorbent filter core material adsorbs the particles in the oil liquid on the filter core, and the magnetic filter is an adsorbent filter, which is made of permanent magnet, and can adsorb iron, iron or magnetic abrasive in the oil. It is usually combined with other types of filters to make duplex filters, and magnetic filters also play a role in monitoring the wear of mechanical equipment.http://www.inocofiltration.com/
