Oil Filter

Oil Filter
Oil filter, oil filtering equipment. By the filter material and structure, can be divided into network-type engine oil filter, line-gap type, paper type filter, oil filter and magnetic sintered filter and so on. Filter placed at different positions, but also can be divided into suction filter, pressure filter and back to the oil filter, taking into account the performance of self-priming pump, suction filter, mostly coarse filter.
Filter indicator
 Hydraulic oil often contains particulate impurities will cause relative movement of hydraulic components, surface wear, catching slide valve, throttling orifice clogging, greatly reduced the reliability of the system work. Installed in the system a certain precision of oil filters, hydraulic system to work is to ensure the necessary means.
      Accuracy is the oil filter filter filter to filter out impurities in the smallest particle size, the diameter d as the nominal size that, according to the precision can be divided into coarse filter (d <100) ordinary filter (d <10 ), fine filter(d <5), special fine filter (d <1). General basic requirements of the oil filter is:    (1) to meet the accuracy requirements of the hydraulic systemengine  filter that can block a certain size of impurities into the system.    (2) The filter should be of sufficient strength, the pressure will not damage.    (3) The flow capacity and pressure loss.    (4) easy to clean or replace the filter. Types and Characteristics (1) comb filter       Comb filter, the filter with copper mesh as filter material, has opened a lot of holes around the plastic or metal tube-shaped skeleton, wrapped in a layer or two layers of copper wire, its accuracy depends on the copper mesh layer filter number and mesh size. This filter structure is simple, flow capacity of a large, easy to clean, but filtering accuracy is low, generally used for the hydraulic pump suction.   Suction filter is usually installed at the pump suction port, to protect pumps and other hydraulic components, in order to avoid inhalation of contaminants, can effectively control the hydraulic system cleanliness.       Return back to the engine oil filter for hydraulic oil filtration system, filtering the hydraulic system due to component wear metal particles generated by the heart generated seals contaminants, so that the oil back into the tank clean.              Currently used are WU-type suction filter coarse filter, and its simple structure, large capacity through oil resistance, easy installation, replacement or repair filter cleaning system is very convenient, and has a filter and oil pollution sender device bypass valve to improve the reliability of the hydraulic system. XU-A back to the oil filter oil filter is fine, its simple structure, high precision filter, replace filter cleaning or maintenance of the system is very convenient, and has a sender filter pollution control and oil by-pass valve, can be very effective improve the reliability of the hydraulic system.
