The so-called oil filter generally refers to a filtering device for filtering hydraulic oil. It is generally composed of a housing and a filter element.
According to the material of the filter element, it can be divided into paper filter oil filter, chemical fiber filter oil filter, glass fiber filter oil filter, stainless steel filter oil filter and so on.
According to the structural form, it can be divided into a net type oil filter, a line gap type oil filter, a folded filter type oil filter, a sintered type oil filter, a magnetic oil filter, and the like.
According to the position where the oil filter is placed, it can also be divided into an oil suction filter, a pipeline oil filter and a return oil filter. Considering the self-priming performance of the pump, the oil suction filter is generally a coarse filter.
Hydraulic cutting machines usually use a net type oil filter. The filter element is made of copper mesh or stainless steel mesh. It is surrounded by a plastic or metal cylindrical frame with many holes around it. It is covered with one or two layers of copper wire mesh. The filtering accuracy depends on the number of layers of the mesh and the size of the mesh. The oil filter has the advantages of simple structure, large flow capacity, convenient cleaning, but low filtration precision, and is generally used for the oil suction port of the hydraulic pump.
