Description
Technical field
The utility model is related to auto parts fields more particularly to a kind of low pressure diesel to pump.
Background technology
Diesel pump is that diesel oil is transported to after being sucked out, pressurizeing in diesel fuel tanks in petroleum pipeline, ensures to hold to atomizer supply
Continuous fuel oil.
The existing usual structure of diesel pump is that fixed ring flange and the pump housing are structure as a whole setting, including such structure
The electrified wire and conducting wire pin in portion are complicated for operation in assembly, cause assembly difficult, and matching requirements are high, and cost is also high；And it is existing
Some structure baffle rings and the pump housing are welded as a whole structure, and production process is complicated, and more importantly the sealing ring on baffle ring exists
Coordinate oil water separator assembly when, due to baffle ring position together with sealing ring in fixed position, after mounting since size is poor
The problem of be easy to causeing and be not tight seal, causing oil leak.
Utility model content
In view of the above problems, the utility model devises a kind of low pressure diesel pump, the existing dress of existing diesel pump has been solved
With difficulty height, with the use of when be not tight seal the problem of.
The technical solution of the utility model is：The pump housing and blind flange are separate structure setting, and the is socketed on blind flange
One sealing ring, middle is socketed with the second sealing ring on the pump housing, and the second sealing of positioning is each provided with about the second sealing ring
The baffle ring of circle, the baffle ring are socketed on the pump housing, and can be moved left and right on the pump housing with the second sealing ring.
Preferably, blind flange right end is equipped with multiple spaced support chips, the blind flange is external by support chip
In pump housing one end.
Preferably, being provided with electrified wire between the pump housing and blind flange, it is horizontally arranged with conducting wire pin on blind flange, leads
Line pin is connected and fixed with electrified wire one end, and the conducting wire pin other end is plugged in blind flange and by vertically arranged electric mortiser
Piece is fixed.
Preferably, pump housing right end position is provided with third sealing ring.
Preferably, pump housing right end movable sleeve is connected to spring base, spring is provided between spring base and the pump housing.
Preferably, baffle ring includes left baffle ring and right baffle ring, the section of left baffle ring and right baffle ring is L-type structure.
The utility model has the beneficial effects that：Compared with prior art, the diesel pump of the utility model is by blind flange and pump
Body is designed as seperated structure type, when to electrified wire and the assembly of conducting wire pin, reduces assembly difficulty；And by setting
The structure of left baffle ring and right baffle ring is set, two baffle rings are removable, in cooperation oil water separator in use, can be to sealing ring
Position be adjusted so that sealing ring is more bonded with oil water separator when cooperation, and sealing effect is more.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Fig. 3 is the side view of the utility model.
1 blind flange in figure, 2 support chips, 3 second sealing rings, 4 pump housings, 5 springs, 6 third sealing rings, 7 spring bases, 8
One sealing ring, 9 baffle rings, 10 electrified wires, 11 electric mortiser pieces, 12 conducting wire pins.
Specific implementation mode
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figs. 1-3, the pump housing 4 of the utility model and blind flange 1 are arranged for separate structure, are socketed on blind flange 1
First sealing ring 8, middle is socketed with the second sealing ring 3 on the pump housing 4, and positioning is each provided with about the second sealing ring 3
The baffle ring 9 of two sealing rings 3, baffle ring 9 are socketed on the pump housing 4, and can be moved left and right on the pump housing 4 with the second sealing ring 3.
1 right end of blind flange is equipped with multiple spaced support chips 2, and blind flange 1 outside support chip 2 by being connected on the pump housing one
End, support chip 2 are the setting structure with 1 one of blind flange, and in assembly, support chip 2 resists baffle ring 9, and baffle ring 9 and second is close
Seal 3 presses down, and assembly is more bonded.
It is provided with electrified wire 10 between the pump housing 4 and blind flange 1, conducting wire pin 12, conducting wire are horizontally arranged on blind flange 1
Pin 12 is connected and fixed with 10 one end of electrified wire, and 12 other end of conducting wire pin is plugged in blind flange 1 and by vertically arranged
Electric mortiser piece 11 fix.
4 right end position of the pump housing is provided with third sealing ring 6, and when being assembled with oil water separator, bottom also functions to sealing
Effect.
4 right end movable sleeve of the pump housing is connected to spring base 7, and spring 5 is provided between spring base 7 and the pump housing 4.
Baffle ring 9 includes left baffle ring and right baffle ring, and the section of left baffle ring and right baffle ring is L-type structure.
Above are merely preferred embodiments of the utility model, for those skilled in the art, exist
Under the premise of not departing from the utility model principle, several improvement can also be made, these improvement also should be regarded as the utility model
Protection domain.
