Abstract
The utility model belongs to auto parts machinery field, it is little for the suction of existing fuel pump and a kind of novel fluid driving type electric fuel punp provided, comprise shell, motor, motor seal safety cover, impeller, filler opening and oil outlet, the output shaft of motor connects impeller, the output shaft of motor connects a spiral helicine soup stick, and soup stick runs through filler opening and arranges; The cross section that the output shaft connection impeller place of motor and output shaft connect soup stick place is rectangular configuration, the output shaft of impeller and motor is fixed by screw, in one end that soup stick is connected with motor output shaft, there is the hole slot that a cross section is rectangle, soup stick is socketed in the end of motor output shaft, and is fixed by screw.The utility model structure is simple, the output shaft end of motor is connected soup stick, makes soup stick also can produce suction, thus the interior negative pressure of fuel pump is increased, practical.
Description
Technical field
The utility model belongs to auto parts machinery field, particularly relates to a kind of novel fluid driving type electric fuel punp.
Background technique
Electric fuel punp is the important spare part in fuel oil supply system, its effect is the fuel oil of continuously fuel system abundance and maintains enough pressure (pressure of oil-fired system keeps constant by pressure regulator valve), to ensure that motor effectively sprays under all operating modes, unnecessary fuel oil flows back to fuel tank.Electric fuel punp can be divided into positive displacement pump and fluid driven pump etc.
Hydrokinetic type electric fuel punp mainly comprises impeller, oil-feed plate and goes out oiled-plate method, oil-feed plate and go out on oiled-plate method to be provided with oil groove, and impeller is driven by motor and rotates.According to hydrokinetic principle, electric machine rotation impeller High Rotation Speed, the impeller of rotation forms negative pressure in turnover oiled-plate method runner, is sucked by fuel oil and accelerates, air separation in fuel oil discharged from exhaust port simultaneously from filler opening.Fuel oil speed can be transformed into pressure energy at turnover oiled-plate method runner by impeller, sets up the pressure of almost stable.Fuel oil flows through fuel pump inside simultaneously, plays lubrication and cooling effect to the armature, carbon brush, bearing etc. of motor.
Early stage hydrokinetic type electric fuel punp is all that gloss impeller drives, and its negative pressure produced is less, causes the suction of electric-motor pump less.
Model utility content
The purpose of this utility model is little for the suction of existing fuel pump and a kind of novel hydrokinetic type electric fuel punp provided.
The utility model is achieved by the following technical solution:
Novel fluid driving type electric fuel punp, comprises shell, motor, motor seal safety cover, impeller, filler opening and oil outlet, and the output shaft of motor connects impeller, and the output shaft of motor connects a spiral helicine soup stick, and soup stick runs through filler opening and arranges.
The cross section that the output shaft connection impeller place of described motor and output shaft connect soup stick place is rectangular configuration, the output shaft of impeller and motor is fixed by screw, in one end that soup stick is connected with motor output shaft, there is the hole slot that a cross section is rectangle, soup stick is socketed in the end of motor output shaft, and is fixed by screw.
Described soup stick and the output shaft of motor are concentric setting.
The big envelope that quality of rubber materials is made is provided with at filler opening place.
The beneficial effects of the utility model: the utility model structure is simple, connect soup stick by the output shaft end of motor, make soup stick also can produce suction, thus the interior negative pressure of fuel pump is increased, practical.
Accompanying drawing explanation
Fig. 1 is the utility model sectional view.
Embodiment
Below in conjunction with embodiment, the utility model is described in further detail.
Embodiment
As shown in Figure 1; novel fluid driving type electric fuel punp, comprises shell 1, motor 2, motor seal safety cover 3, impeller 4, filler opening 5 and oil outlet 6, and the output shaft 7 of motor connects impeller 4; the output shaft 7 of motor connects a spiral helicine soup stick 8, and soup stick 8 runs through filler opening 6 and arranges.The output shaft 7 of described motor connects the cross section that impeller 4 place and output shaft 7 connect soup stick 8 place and is rectangular configuration, impeller 4 is fixed by screw with the output shaft 7 of motor, in one end that soup stick 8 is connected with motor output shaft, there is the hole slot that a cross section is rectangle, soup stick 8 is socketed in the end of motor output shaft, and is fixed by screw.Described soup stick 8 is concentric setting with the output shaft 7 of motor.The big envelope 9 that quality of rubber materials is made is provided with at filler opening place.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope, simple change and the replacement of those ordinary skill in the art are all within protection domain of the present utility model.
