The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, the diesel oil pre-filtrating equipment of the automatic warning function of described band, comprise housing, be arranged on absolute oil chamber 11, filter chamber 12 and three double-stage filtering filter cores 1 that are laid in enclosure interior symmetrically of enclosure interior, wherein said housing comprises housing sidewall 2, case lid 10 and housing base 9, each several part adopts the extrusion process one-shot forming, offer oil-in 3, oil-out 4, sewage draining exit 5 and differential pressure transmitter device installing port 14 on the housing sidewall 2,12 of absolute oil chamber 11 and filter chambers are the boundary with dividing plate 8, and absolute oil chamber 11 is positioned at filter chamber 12 bottoms.The housing cross section is oval, and case lid 10 is fixedly mounted on the housing sidewall 2 by bolt 15 with housing base 9.Described shell structure is integrated, and external form is light and handy and easy to use, the installation site is flexible, and housing is material with the aluminium alloy and adopts the extrusion process one-shot forming, thereby can additionally not increase metal impurities.
