Mesh type filter element is a filter core with one or two layers of copper wire mesh covered on the porous U cylinder framework. The accuracy is the diameter of the mesh, convenient cleaning, and can be used repeatedly,
but the accuracy is low, so it can be used as an oil-absorbing filter element.
Gap type filter element:
This is a filter element with copper wire or aluminum wire tightly wound on the cylinder frame. The oil passes through the pores between the metal lines, enters the interior, and then flows out from the upper hole.
This filter has a simple structure and large flux, and is mostly used for oil return filtration.
Paper filter:
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.
