Specific implementation mode
As shown in Figure 1, injection fuel oil pump assembly built in this distal end oil suction band includes shell 1, fuel pump 6, flowline
5, oil return pipe 6 and float 2, fuel pump 6 are mounted in shell 1, and fuel pump 6 is connect with flowline 7.This is common fuel oil
Pump assembly structure, in order to achieve the purpose that a fuel oil pump assembly realizes two fuel tank fuel feeding.The utility model is pacified on shell 1
Equipped with distal end injection fuel sucking pipe 3, one end of the distal end injection fuel sucking pipe 3 is located in auxiliary fuel tank, and the other end and shell 1 together position
In in main fuel tank, jet pump 7, oil outlet and 3 phase of distal end injection fuel sucking pipe of the jet pump 7 are equipped in the oil outlet end of oil return pipe 4
It is logical, and the oil outlet of the oil outlet of distal end injection fuel sucking pipe 3 and jet pump 7 is point-blank and towards the same direction.
When work, fuel oil provides fuel oil from flowline 5 to engine, and extra fuel oil returns to main fuel tank through oil return pipe 4
It is interior, as shown in Figure 1,4 intermediate fuel oil of oil return pipe, after jet pump 7, pressure energy is converted to kinetic energy, and flow velocity increases, to drive week
The fluid on side is flowed to flow velocity direction, and negative pressure is formed in this way around jet pump 7, to which the fuel oil in auxiliary fuel tank is passed through distal end
Injection fuel sucking pipe 3 is introduced into main fuel tank.By this structure, a fuel oil pump assembly in auxiliary fuel tank can be saved, to
Substantially reduce cost.
Fuel pump 6 is used as core, as shown in Fig. 2, it includes the pump housing 60, impeller 68, motor and oil suction lid 61,
Oil suction lid 61 is mounted on 60 bottom of the pump housing, and impeller 68 is connect with motor drive, and in the pump housing 60, impeller 68 passes through motor
Driving, and will be pumped into fuel from fuel tank in the pump housing 60.Impeller 68 is equipped with oil inlet close to oil suction lid 61 on oil suction lid 61
62, fuel oil is exactly to be entered in the pump housing 60 by the oil inlet 62；Oil pressure to increase, the utility model is in oil suction lid 61
It is equipped with not closed annular oil groove 64 towards the one side of impeller 68, as shown in Figure 3 and Figure 4, one end of annular oil groove 64 is equipped with
Inlet port 63, inlet port 63 are communicated with oil inlet 62, and the other end of annular oil groove 64 has the oil groove tail for gradually narrowing and shoaling
End 65.When 68 high-speed rotation of motor impeller, fuel oil enters from oil inlet 62, and enters annular oil groove by inlet port 63
In 64, since oil groove tail end 65 becomes narrow gradually and shoals, the fuel flow rate of high-speed motion reduces, and kinetic energy is converted into pressure energy, most
It is sprayed afterwards with the fluid of high pressure, to give engine oil.
In order to enable fuel oil to be entered in annular oil groove 64 from inlet port 63 more glibly, the utility model is in inlet port
There are one guide oil slopes 67 for tool between 63 and annular oil groove 64.When fuel oil is from inlet port 63 into fashionable, just pass through the guide oil slope
67 enter in annular oil groove 64, and to keep the supply of fuel oil more unobstructed, that improves fuel oil goes out oil pressure.
For the purposes of improving out oil pressure, as shown in figure 3, the oil inlet 62 of the utility model oil suction lid 61 is in funnel-form,
The osculum of oil inlet 62 is communicated with inlet port 63.Since the oil inlet 62 of oil suction lid 61 is in funnel-form, fuel oil can be with higher pressure
The flow of power and bigger enters in the pump housing 60.In addition, the utility model also adds the width of annular oil groove 64, turn in motor
In the case that speed is constant, by the width of increase annular oil groove 64, acceleration time of the fuel oil in annular oil groove 64 can be increased,
To obtain higher flow velocity, to achieve the purpose that supercharging.Here it is worth noting that in order to improve the flow of fuel pump,
Oil absorption can be increased by increasing the depth of annular oil groove 64, to achieve the purpose that increase flow.
As shown in figure 5, the impeller 68 of the utility model is cylinder, several oil-through-holes 69 are distributed on impeller 68, if
The dry arrangement of oil-through-hole 69 circularizes, and corresponding in position with the annular oil groove of oil suction lid 61 64.Fuel oil enters annular oil
After in slot 64, just entered in the pump housing 60 by the oil-through-hole 69 on impeller 68.The utility model also adds the logical of impeller 68
The diameter of oilhole 69, when impeller 68 works around the flowing velocity of fuel oil increase therewith, the fuel delivery of fuel pump also increases therewith
Add, meanwhile, the pressure energy of kinetic energy conversion increases, and the output pressure of fuel pump increases.
