The hydraulic system of pollution has a direct impact on the entire hydraulic system is good or bad. Hydraulic system is currently facing the need to overcome the problem of how to effectively reduce and control pollution of the system to ensure that a variety of hydraulic components and overall system reliability and service life.Thus, rational analysis, and effective control of pollution of the hydraulic system is to ensure that the hydraulic system or industrial hydraulic systems work properly and prolong the life of the key.
(1), the filtration precision according to the needs of the hydraulic system to determine the level of cleanliness with stains, choose the filtering accuracy of the oil filter according to this cleanliness level according to the symbol table.
(2) the nominal filter accuracy can not be a true reflection of the filtering capacity of the filter, therefore, can often filter in the prescribed test conditions, the diameter of the largest hard spherical particle as its absolute filtration precision to reflect the newly installed filter the initial filtering capabilities.
