Abstract
The utility model discloses a kind of fuel pump impeller with side blade groove, form and comprise interior disk (8), middle annulus (7) and outer toroid (6), the intra vane (3) be obliquely installed is provided with between described interior disk (8) and middle annulus (7), the outer leafs (4) be obliquely installed is provided with between described middle annulus (7) and outer toroid (6), the center of described interior disk (8) is provided with motor mounting hole (1), motor mounting hole (1) is provided with balance lubrication hole (2) around, the side of described outer toroid (6) is provided with side blade groove (5).The utility model can improve the pressure of pressure tank, maintains continuing of fuel flow, thus ensures the stable operation of fuel pump, can also prevent fuel oil side leakage.
Description
Technical field
The utility model relates to a kind of fuel pump impeller, particularly a kind of fuel pump impeller with side blade groove.
Background technique
Fuel pump is the vitals in vehicle fuel supply system, is one of key components and parts of motor car engine.In prior art, what electric fuel punp usually adopted is circumference flow type blade wheel, and this impeller number of plies is single, and fuel flow communication passage is few, often there is delivery pressure low, the defects such as flow is little; Due to the existence of accuracy of manufacturing, impeller is installed in the duct, can cause fuel oil side leakage to a certain degree during fuel pump work, brings larger impact to the normal work of fuel pump and stable performance.
Model utility content
The purpose of this utility model is, provides a kind of fuel pump impeller with side blade groove.The utility model can improve the pressure of pressure tank, maintains continuing of fuel flow, thus ensures the stable operation of fuel pump, can also prevent fuel oil side leakage.
The technical solution of the utility model: a kind of fuel pump impeller with side blade groove, it is characterized in that: comprise interior disk, middle annulus and outer toroid, the intra vane be obliquely installed is provided with between described interior disk and middle annulus, the outer leafs be obliquely installed is provided with between described middle annulus and outer toroid, the center of described interior disk is provided with motor mounting hole, be provided with balance lubrication hole around motor mounting hole, the side of described outer toroid is provided with side blade groove.
Aforesaid have in the fuel pump impeller of side blade groove, and the angle of inclination of described outer leafs is 6-50 °.
Aforesaid have in the fuel pump impeller of side blade groove, and the angle of inclination of described intra vane is 6-50 °.
Aforesaid have in the fuel pump impeller of side blade groove, and described balance lubrication hole is 3-5, is evenly distributed on around motor mounting hole.
Compared with prior art, the utility model is by utilizing the draft angle of blade, and double-leaf and the multilayer flow passage that formed by side blade groove, eddy flow is produced when fuel pump is worked, improve the pressure of pressure tank, maintain continuing of fuel flow, thus ensure the stable operation of fuel pump.Of the present utility model rational in infrastructure, utilization efficiency is high, greatly improves the working life of impeller, has good Performance And Reliability.Side blade groove of the present utility model is evenly distributed on the side of cylindrical, and when can prevent fuel pump from working, fuel oil is at pipeline gap leakage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-motor mounting hole, 2-balances lubrication hole, 3-intra vane, 4-outer leafs, 5-side blade groove, 6-outer toroid, annulus in the middle of 7-, disk in 8-.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described, but not as the foundation limited the utility model.
Embodiment.A kind of fuel pump impeller with side blade groove, form as shown in Figure 1, comprise interior disk 8, middle annulus 7 and outer toroid 6, the intra vane 3 be obliquely installed is provided with between described interior disk 8 and middle annulus 7, the outer leafs 4 be obliquely installed is provided with between described middle annulus 7 and outer toroid 6, the center of described interior disk 8 is provided with motor mounting hole 1, and be provided with balance lubrication hole 2 around motor mounting hole 1, the side of described outer toroid 6 is provided with side blade groove 5.
The angle of inclination of described outer leafs 4 is 6-50 ° (can be 6 °, 15 °, 25 °, 35 °, 45 °, 50 °).
The angle of inclination of described intra vane 3 is 6-50 ° (can be 6 °, 15 °, 25 °, 35 °, 45 °, 50 °).
Be preferably outer leafs 4 consistent with the angle of inclination of intra vane 3.
Described balance lubrication hole 2 is 3-5, is evenly distributed on around motor mounting hole 1.
The utility model is by utilizing the draft angle of blade, and double-leaf and the multilayer flow passage that formed by side blade groove, produce eddy flow when fuel pump is worked, improve the pressure of pressure tank, maintain continuing of fuel flow, thus ensure the stable operation of fuel pump.Of the present utility model rational in infrastructure, utilization efficiency is high, greatly improves the working life of impeller, has good Performance And Reliability.Side blade groove of the present utility model is evenly distributed on the side of cylindrical, and when can prevent fuel pump from working, fuel oil is at pipeline gap leakage.
