Hydraulic oil filter element is mainly used for oil filtration in hydraulic system. It is installed in the filter and oil filter in hydraulic system. According to the installation position in the hydraulic system, the hydraulic oil filter element is divided into oil filter element of oil suction pipeline, oil filter element of pressure pipeline and oil filter element of oil return pipeline. The following by Meng Ma filter for you to explain the classification of oil filter element and different uses:
Oil suction pipe hydraulic oil filter: oil suction pipe (oil tank - hydraulic pump inlet) or directly installed in the oil tank is a necessary measure to protect the hydraulic pump, its accuracy is generally 100 ~ 180μm, depending on the self-priming capacity of the pump to determine, flow resistance is too large to lead to cavitation of the hydraulic pump.
Pressure pipeline hydraulic oil filter element: The pressure pipeline oil filter element is not only to protect its downstream components, as the main oil filter to ensure the degree of oil pollution in the system, through its own efficient purification of the oil, the hydraulic pump also plays a good protective role, the filtration accuracy is 5-10 μm, the filter is under large pressure, vibration is also very important, the pressure pipeline oil filter element allowable differential pressure, according to different pressure levels, The range is 0.3 to 0.7MPa.
Since there is no unified filter division method, the characteristics of various filters can be classified and summarized. According to the pressure level, the filters can be divided into three categories: high pressure filter, low pressure filter and medium pressure filter. The difference between the three filter standard line is 16Mpa and 1.6Mpa, pressure greater than 16Mpa is called high pressure filter, less than 16Mpa(including 16Mpa) but greater than 1.6Mpa is called medium pressure filter, less than 1.6Mpa(including 1.6Mpa) is called low pressure filter.
