Background technique
In recent years, in the motorcycle fuel supply system, the use of turbine fuel pump more and more widely.The pump housing of turbine fuel pump mainly comprises turbine, pump chamber and pump cover, and pump chamber is relative with pump cover thirty years of age, middlely forms a cavity, and turbine is positioned at wherein.The turbine circumference is provided with many turbine blades, offers with the corresponding position of turbine on the pump chamber and is equipped with suitable runner.When armature drove the turbine rotation, turbine drove the runner of fuel oil in flange that is flowed into by filler opening and extrudes from oil outlet, realized fuel feeding.But, existing turbine fuel pump inside does not have filtration, the mode that only adopts one-level to filter, the only filtration of process one deck filter screen before entering fuel pump of fuel oil, enter the inferior quality of the fuel oil in the fuel pump, impurity in the bad oil product is more serious to the wearing and tearing of fuel pump internal structure, makes the life-span of fuel pump reduce greatly.In addition, this kind fuel pump is built-in fuel pump, and is higher to the size requirements of fuel tank volume, only is fit to be installed in the fuel tank internal that is complementary, and use the inside that can not be installed in the motorcycle tank of all kinds of sizes, and versatility is not high.
The model utility content
The purpose of this utility model is to provide a kind of intellectual electric fuel punp, with the technical problem of turbine fuel pump weak point in working life and versatility difference in the solution prior art.
For achieving the above object, the utility model provides a kind of intellectual electric fuel punp, comprise pump case, go out font, armature, upright and the oil-feed seat of pump chamber group, go out the end that font is connected to pump case, armature and pump chamber group are upright to be arranged in the pump case, armature with go out font and be connected, the pump chamber group is upright to be connected with armature, and the oil-feed seat is connected to the other end of pump case, the upright tubular bearing that further comprises of pump chamber group, pump chamber, turbine, pump cover, pump cover nail and filter screen, tubular bearing and pump chamber socket, pump cover is connected with pump chamber by the pump cover nail, the inner cavity that forms, and turbine is arranged in the cavity, pump cover is provided with filler opening, and filter screen is connected to filler opening.
According to the described intellectual electric fuel punp of the utility model preferred embodiment, its filter screen is a double-layer leaching net.
Compared with prior art, the utlity model has following advantage:
1, this intellectual electric fuel punp is provided with filter screen at the filler opening place of pump cover, and filter screen is a double-layer leaching net, under the double filtration of this filter screen, the fuel oil that enters fuel pump inside can reach cleaner state, improved fuel qualities, the wearing and tearing of fuel pump inner body are dropped to minimum, the working life of having improved fuel pump greatly, long service life.
2, the volume of this intellectual electric fuel punp is little, can be installed in the motorcycle tank inside of all kinds of sizes, the versatility height.
3, this intellectual electric fuel punp adopts fluid simulation design, the appropriate design turbine blade and and corresponding pump chamber of turbine and pump cover on runner, reduced vibration and noise, and improved pump oil efficient.
4, the sensitivity of this intellectual electric fuel punp is higher, also can reach system pressure under 8V voltage, also can start fast under the low voltage, has guaranteed the normal startup of motorcycle.
Description of drawings
Fig. 1 is the intellectual electric fuel oil pump structure of a utility model sectional view;
Fig. 2 is the utility model embodiment's the upright explosive view of pump chamber group.
Embodiment
Below in conjunction with accompanying drawing, specify the utility model.
See also Fig. 1 to Fig. 2, a kind of intellectual electric fuel punp, comprise pump case 11, go out font 12, armature 13, pump chamber group upright 14 and oil-feed seat 15, go out the end that font 12 is connected to pump case 11, armature 13 and pump chamber group upright 14 is arranged in the pump case 11, armature 13 with go out font 12 and be connected, pump chamber group upright 14 is connected with armature 13, oil-feed seat 15 is connected to the other end of pump case 11.
Pump chamber group upright 14 comprises tubular bearing 141, pump chamber 142, turbine 143, pump cover 144, pump cover nail 145 and filter screen 146, tubular bearing 141 and pump chamber 142 sockets, pump cover 144 is connected with pump chamber 142 by pump cover nail 145, the inner cavity that forms, turbine 143 is arranged in the cavity, pump cover 144 is provided with filler opening 1441, and filter screen 146 is connected to filler opening 1441.
In this example, in order to reach preferable filtering effect, filter screen 146 adopts double-layer leaching net, as shown in Figure 2, filter screen 146 comprises inner filter screen 1461, lasso 1462 and outer filter 1463, and inner filter screen 1461 and outer filter 1463 are connected to lasso 1462 both sides respectively.But, in this example, need to prove that the utility model does not limit the type of filter screen 146, in practical application, can select suitable filter screen as required, for example, can also adopt individual layer filter screen or even multistorey strainer mesh, therefore, adopting double-layer leaching net with upper filter screen 146 is an example, and is not used in qualification the utility model.
