Description
Technical field
The utility model relates to the oil-feed end cap of the turbine pump in a kind of automotive fuel oil system.
Background technique
Automotive fuel oil system turbine pump oil-feed end cap, automotive fuel oil system turbine pump, comprise pump case, described pump case forms after being docked by oil-feed end cap and fuel-displaced end cap, forms pump chamber after described oil-feed end cap and the docking of fuel-displaced end cap, turbine is rotatablely equipped with in pump chamber, described oil inlet end covers the oil inlet passage being provided with and communicating with pump chamber, and described oil outlet end covers the oil discharge passage being provided with and communicating with pump chamber, at present, the inwall of oil inlet passage is tiltedly to be faced directly, and oil inlet passage is straight passage.As Figure 1-3.Fuel oil imports in pump chamber through filler opening, and then goes out from the oil outlet of pump case.The noise that turbine produces also just and then directly is diffused into outside from oil inlet passage, causes the sound pressure level of whole turbine pump core 30-50 order and frequency multiplication to raise, and noise is large, and spectrum measurement is shown in Fig. 4.
Model utility content
For existing problem, the purpose of this utility model is to provide a kind of automotive fuel oil system turbine pump oil-feed end cap reducing noise.
To achieve these goals, the technical solution of the utility model is: a kind of automotive fuel oil system turbine pump oil-feed end cap, comprise oil-feed end cap body, described oil-feed end cap body is provided with oil inlet passage, it is characterized in that: described oil inlet passage bends near the position of oil outlet end, the bending angle of described kink is less than 90 °, and the inwall near the oil inlet passage of kink end is provided with baffle plate, and described baffle plate is positioned on the inwall of the oil inlet passage of the side away from kink overbending direction.
Adopt such scheme, fuel oil imports in turbine pump pump chamber by such fuel gallery, the sound that turbine in pump chamber produces by oil inlet passage to when external diffusion, be subject to the stop of the inwall at baffle plate and oil inlet passage kink place, noise cannot be spread in pump chamber, effectively can reduce the impact of 30-50 order and frequency multiplication noise, spectrogram is shown in Fig. 9.
In such scheme: the diameter of described oil inlet passage reduces gradually from oil inlet end to kink.Be conducive to fuel oil like this to accelerate through.
In such scheme: the inwall of described oil inlet passage is the arc inner wall of rounding off.Be conducive to the importing of fuel oil.
In such scheme: the length of described baffle plate is greater than 1/2nd of the width of this place's oil inlet passage.So more be conducive to blocking noise to external diffusion.
The beneficial effects of the utility model are: the utility model structure is simple, easy to use, do not affect the oil-feed of turbine pump, can effectively reduce the 30-50 order that turbine sends and frequency multiplication noise to pump case external diffusion, reduce automotive fuel oil system turbine pump noise, improve vehicle ride comfort.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further described:
Of the present utility modelly wait the relative position of the noun of locality only in representative graph all around, do not represent the absolute position of product.
Embodiment 1
As shown in figures 5-9: automotive fuel oil system turbine pump of the present utility model is made up of parts such as pump case 1, pump chamber 2, oil inlet passage 3, baffle plate 4, turbine 5, oil discharge passages 6.
As shown in Figure 5, pump case 1 is formed with the oil-feed end cap docking being positioned at right side by the fuel-displaced end cap 1-2 being positioned at left side.Oil-feed end cap comprises oil-feed end cap body 1-1, and form pump chamber 2 after oil-feed end cap and fuel-displaced end cap 1-2 dock, pump chamber 2 is positioned at pump case 1, is rotatablely equipped with turbine 5 in pump chamber 2.Specifically, the face that fuel-displaced end cap 1-2 docks with oil-feed end cap is provided with groove, the center hole extended about fuel-displaced end cap 1-2 is also provided with axis, after oil-feed end cap and fuel-displaced end cap 1-2 dock, this groove forms pump chamber 2, and the rotating shaft of turbine 5 is stretched into from the center hole of fuel-displaced end cap 1-2 and is connected with the center hole of turbine 5.Be provided with on oil-feed end cap body 1-1 top the oil inlet passage 3 communicated with pump chamber 2, be provided with in fuel-displaced end cap 1-2 bottom the oil discharge passage 6 communicated with pump chamber 2, this is prior art, does not repeat at this.The diameter of oil inlet passage 3 reduces from the one end (oil inlet end) away from pump chamber 2 gradually to kink.The inwall of oil inlet passage 3 is the arc inner wall of rounding off.
Oil inlet passage 3 bends near the position (near oil outlet end) of pump chamber 2, the bending angle of kink is less than 90 °, as shown in Figure 5, oil inlet passage 3 first upwards bends near the part of pump chamber 2, and then horizontal transition is connected with pump chamber 2, inwall near the oil inlet passage 3 of kink end is provided with baffle plate 4, and baffle plate 4 is positioned on the inwall away from the oil inlet passage 3 of the side of kink overbending direction, and has distance between the inwall of the close overbending direction of baffle plate 4 and oil inlet passage 3.As shown in Figure 5, the downside sidewall of oil inlet passage 3 is provided with baffle plate 4, the length of baffle plate 4 is greater than the half of the width of this place's oil inlet passage 3, if oil inlet passage 3 is circular channel, then the length of baffle plate 4 is greater than the radius of this place's oil inlet passage 3.
Like this, fuel oil enters pump chamber 2 by oil inlet passage 3, and the noise that turbine 5 produces is blocked by the inwall of the oil inlet passage 3 of baffle plate 4 and kink, noise cannot be spread out, effectively can reduce 30-50 order and frequency multiplication noise thereof.
