Aviation kerosene refined filter / Jet fuel filter separator structure:
Aviation kerosene refined filter/aviation fuel filter separator is a metallic housing internally fitted with a primary filter element (coalescing filter element), a secondary filter element (separation filter element), and is equipped with manual and automatic exhaust valves (as per customer requirement), stainless steel drain valves, differential pressure gauges, direct-reading differential pressure meters (as per customer requirement), on-line sampling probe valves, sampling connectors, safety valves (as per customer requirement), water level monitors (as per customer requirement), and heating devices (as per customer requirement in cold regions). 2. Working principle of aviation kerosene refined filter/aviation fuel filter separator:
Jet fuel enters the aviation kerosene refined filter/jet fuel separator, first accumulating on an aluminum tray, then dispersing into the agglomeration filter core from the inside out. The solids are filtered out by the filter layer, passing through the demulsification layer to separate emulsified oil and water. In the third step, the agglomeration layer gathers tiny water droplets into larger ones, which settle in the water collection trough. Then, the remaining unagglomerated small water droplets are further separated and settled in the sedimentation trough by the repelling action of the separator filter core, and are drained out through the drain valve. The clean fuel accumulates on the secondary tray through the separator filter core and is discharged from the outlet of the aviation kerosene refined filter/jet fuel separator. 3. Service life of aviation kerosene refined filter/jet fuel separator:
The operational status of aviation kerosene fine filters/jet fuel filter separators, as well as the service life of the filter cores, are primarily determined by pressure difference. When the pressure difference between the inlet and outlet reaches 0.1 MPa (1.0 kg/cm²), it indicates that the coalescing filter core is clogged and should be replaced. Additionally, filter cores should be considered for replacement after more than six months of use. The separation filter cores are in a cartridge design and can be used for a long time without mechanical damage, but they should be removed, cleaned, and inspected when replacing the coalescing filter cores.
