Further, the magnetic filter plate is made of hard magnetic materials.
The theory of operation, this locomotive city rail fuel fine filter accessory, during the use, in fuel entered the shell from the oil pipe, the magnetism filter plate carried out the primary filtration to it, because the characteristic of magnetism filter plate, tiny iron particle in the adsorbable fuel, then filter paper carries out the secondary filtration to moisture in the fuel, then the fuel after double-deck filtration gets into in the inner shell from the filtration pore, flows into in the fuel engine through going out the oil pipe at last.
(III) advantageous effects
The utility model provides a locomotive city rail fuel fine filter accessory which has the following beneficial effects:
(1) this locomotive city rail fuel fine filter accessory through set up the magnetism filter plate inside the shell, can adsorb its inside tiny iron particle when burning oil and flowing through, reduces the harm of tiny iron particle to the engine, through set up filter paper inside the inner shell, filter paper can adsorb the filtration to moisture in the fuel, makes the fuel filter more thoroughly, increases engine life.
(2) The design that the outer shell, the inner shell and the oil outlet pipe are coaxially arranged can enhance the mechanical strength of the oil filter fitting, and the oil filter fitting is not easy to damage; the design that the filter paper is in a broken line shape and surrounds the outer side wall of the inner shell can increase the contact area of the filter paper and fuel oil and improve the filtering efficiency.
