Description
Technical field
The utility model relates to a kind of fuel pump oil catcher, is meant a kind of fuel pump oil catcher that prevents that locomotive engine is flame-out suddenly especially.
Background technique
As shown in Figure 1; The fuel pump device of the locomotive of knowing has a fuel tank and a fuel pump 11, this fuel tank be plastic cement with the injecting glue moulding, have an opening; This fuel pump 11 is positioned at fuel tank and has plate lid 13, one body 14, one oily line, a motor 16 and a buoy 17; These body 14 upper ends have an oil-feed port and a return opening, and body 14 is inserted in the fuel tank from opening, and seal opening with plate lid 13; Motor 16 and buoy 17 all install on body 14; This oil line is positioned at body 14 and divides expenditure one fuel supply line 18 and a return tube 19.
Owing to lack oil catcher, when only remaining a little fuel oil of fuel tank and locomotive advanced, oily line can't touch to fuel tank bottom pasta, makes motor 16 can't make oily line extraction fuel oil to fuel supply line 18, causes locomotive engine flame-out suddenly.
Have shown in Figure 2; The fuel pump device of the locomotive that another is known has a fuel tank 20, a fuel pump 21 and an oil trap 22; This fuel tank 20 has a upper casing 23 made of iron and a lower casing 24; Mode with spot welding engages upper casing 23 and lower casing 24, and this upper casing 23 has an opening 26, and this oil trap 22 is welded in the lower casing 24 of fuel tank 20.
This fuel pump 21 has a body 27, one oily line, plate lid 25 and one motor 29, and this body 27 has an oil-feed port and a return opening, and this body 27 is inserted in the fuel tank 20 from opening 26, and seals opening 26 with plate lid 25.This motor 29 is positioned at fuel tank 20 and installs on body 27; This oil line is positioned at the inside of body 27 and divides expenditure one fuel supply line 31 and a return tube 32, and this fuel supply line 31 can expose plate lid 25 from the oil-feed port extension; This return tube 32 also can expose plate lid 25 from the return opening extension.
When remaining a little fuel oil of 20 of fuel tanks and locomotive advanced, oil trap 22 can make oily line touch to the pasta of fuel tank 20 bottoms locomotive engine can not stopped working suddenly; Though the design of oil trap 22 is arranged, oil trap 22 is welded in the lower casing 24 of fuel tank 20, makes the manufacture process of fuel tank 20 need process upper casing 23 and lower casing 24 respectively, will improve processing cost.Therefore, to the problems referred to above be the purpose of the utility model research.
The model utility content
When remaining a little fuel oil of fuel tank and locomotive advance, because of oily line can't draw the fuel oil of fuel tank, often cause locomotive engine flame-out suddenly, the purpose of the utility model is to provide a kind of fuel pump oil catcher that prevents that engine is flame-out suddenly and cut down finished cost.
The utility model is characterised in that: a kind of fuel pump oil catcher, it is characterized in that, and include:
One places the oil box in the fuel tank, has a groove, and this groove has an at least one through hole and a fixing part; And
One places the fuel pump in the fuel tank, has a body and at least one oily line, and this body connects this fixing part, and this oil line touches to this groove bottom.
The advantage of the utility model: the utility model not only can reduce production costs, and is flame-out suddenly in the time of can also effectively preventing locomotive operation, thereby the minimizing accident takes place.

Embodiment
As shown in Figure 3, a fuel pump is provided with a fuel tank 40 and fuel pump oil catcher, and the top of this fuel tank 40 is provided with an opening 41, and this opening 41 has an annular groove 42, and this fuel pump oil catcher comprises an oil box 50 and a fuel pump 60.
As shown in Figure 4, this oil box 50 includes a groove 51 and a fixing part 52, and this groove 51 has an inclined-plane 53, and this inclined-plane 53 has at least one through hole 54, and this fixing part 52 has several fixed holes 55.
Like Fig. 4, Fig. 5, shown in Figure 6, this fuel pump 60 is used for drawing fuel oil and stresses on the fuel oil that is drawn, and it has a body 61, a motor 62, at least one oily line 63, a buoy 64 and plate lid 65; This body 61 has an oil outlet and a return opening, and 61 lockings of this body make body 61 be fixed on the fixing part 52 and are positioned at groove 51 on fixed hole 55; This oil line 63 is positioned at the inside of body 61.
This motor 62 is positioned at groove 51 and installs on body 61, supplies to drive fuel pump 60 and draws fuel oil; This buoy 64 installs on body 61 and is positioned at outside the groove 51, how much supplies oil amount determination; This plate lid 65 is positioned at the top of body 61, and it has a packing ring 66; The degree of depth of this oil line 63 can be touched to the fuel oil of groove 51 bottoms; And it divides expenditure one fuel supply line 67 and a return tube 68; This fuel supply line 67 can expose plate lid 65 from the oil-feed port extension; Be used for fuel oil is directed to sparger, this return tube 68 can expose plate lid 65 from the return opening extension, is used for fuel oil is guided in the oil sump tank 40.
Like Fig. 3, Fig. 5, shown in Figure 6, the body 61 that will be fixed in oil box 50 passes opening 42, the packing ring 66 of plate lid 65 is inserted in the annular groove 42 of this opening 41 again, makes plate cover 65 sealed opens 41, makes the fuel pump oil catcher be positioned at fuel tank 40.
When the fuel oil of fuel tank 40 remaining a little and locomotive advanced, fuel oil can flow through through hole 54 and be concentrated in the groove 51, and because of oily line 63 touches to the bottom of groove 51, motor 62 can drive oily line 63 draw fuel oil to fuel supply line 67, and locomotive engine can not stopped working suddenly; In addition, because of oil box 50 and fuel pump 60 are fixed together,, cut down finished cost greatly so can make fuel tank 40 one-body moldedly.
The above person is merely the preferred embodiment of the utility model, and all changes of being done according to the utility model technological scheme when the function that is produced does not exceed the scope of the utility model technological scheme, all belong to the protection domain of the utility model.
