Classification of filter cartridges:
Filter cartridges are divided into two categories: filtering liquids (water or lubricating oil) and filtering gases (air).
Common filter materials are mainly divided into: paper, synthetic fiber, metal mesh, metal powder sintering, PP filter, wire gap, activated carbon, etc.
The common names for hydraulic filter elements include oil suction filter element, pipeline filter element, and return oil filter element.
Main parameters of filter element:
1. Oil filter:
In terms of performance, the main references are: filtration accuracy, filtration material, working pressure, flow rate, and working temperature. The filtering materials are divided into glass fiber, metal mesh, asbestos, etc. According to accuracy, the better the accuracy, the higher the material requirements; The standard for work pressure is 1.0Mpar; The working temperature is generally -30 ℃ to+110 ℃.
The main reference for structural parameters is the depth of the end cap, base, and filter screen. The end cap and base involve the installation of the filter; The depth of the filter is related to the flow rate.
2. Air filtration:
In terms of performance, the main references are: filtration accuracy, filtration material, working pressure, flow rate, and water separation efficiency. The filtering materials are divided into glass fiber, metal mesh, asbestos, etc. According to accuracy, the better the accuracy, the higher the material requirements; The standard for work pressure is 1.0Mpar; The water separation efficiency is generally not less than 80%.
The main reference for structural parameters is the depth of the end cap, base, and filter screen. The end cap and base involve the installation of the filter; The depth of the filter is related to the flow rate.
