Cement Plant Lube Filter KF-40A*120D

The filter element seal mainly adopts the combination of tetrafluoroethylene + O-ring, which has achieved the requirement of no leakage. The filter element adopts an integrated design, which is convenient to replace. The filter material is usually glass fiber and stainless steel, and the filtration accuracy can be made according to customer requirements.

The hydraulic system filter mainly has the following three performance indicators:

Filtration accuracy, filtration accuracy represents the filter's ability to filter various pollutant particles of different sizes, and it is evaluated by indicators such as absolute filtration accuracy, filtration ratio and filtration efficiency. . Absolute filtration accuracy: refers to the size of the large hard spherical particles passing through the filter element, which reflects the size of the large through holes in the filter material, and can be measured by experimental methods. Filtration ratio: refers to the ratio of the number of particles larger than a given size in the unit volume of the upstream oil of the filter to the number of particles larger than the same size in the unit volume of the downstream oil. The filtration ratio performance accurately reflects the filter's ability to filter particles of different sizes. It has been adopted by the International Organization for Standardization as a performance index to evaluate the filter accuracy of the filter. Generally, the filtration accuracy of the system is required to be less than half of the clearance of the movement pair. In addition, the higher the pressure, the higher the requirement for filtration accuracy.
