Structural profile of hydraulic filter elements in different principles

Structural profile of hydraulic filter elements in different principles

1.Mesh filter element: 
the mesh filter core is a filter core covered with one or two layers of copper wire mesh on a porous u-tube skeleton. The accuracy is both mesh diameter, easy to clean and reusable, but the accuracy is low.

2.Wire-gap filter cartridge, 

which is a filter core tightly wrapped around the tubular frame with copper or aluminum wires. The oil goes through the pores between the metal wires, enters the interior, and then flows out from the upper pore channel.

3.paper filter

the structure is similar to line seam type, filter material to filter paper, however, the precision can reach 5 ~ 30 microns, work pressure in 32 mpa, compact structure, large flux, the disadvantage is that cannot be cleaned and filter to change often, filter consists of three layers structure in the figure, outer layer is the thick steel plate net, middle is folded filter paper, layer with wire mesh and filter paper folded together.

4.Sintered filter core is a kind of filter core made by melting and bonding particle metal powder through the high-temperature surface. The accuracy of the filter core is the gap between particles, that is, the size of particles determines the accuracy. The range is between 10 and 100 microns. The sintered filter core has high strength, good impact resistance and corrosion resistance, so it can be installed in different locations, but the cost of this filter core is high.

5.The magnetic filter is also a classification. It uses the adsorption of a magnet to remove iron impurities in the oil. However, since the magnetic filter can only filter iron, it is incapable of consuming a considerable portion of non-ferrous impurities, so this is usually the case. Filter return oil or auxiliary filtration of other filters
