Abstract
The utility model provides a hydrodynamic electric oil fuel pump, which comprises a pump body. The pump body comprises an impeller, an oil inlet plate and an oil outlet plate. The hydrodynamic electric oil fuel pump is characterized in that the impeller comprises a circular impeller body; an annular slotted hole is arranged on the impeller body along the inner side of the outer edge of the impeller body; a plurality of same blades are uniformly arranged in the slotted hole; one ends of the blades face to the oil plate; the other ends of the blades face to the oil outlet plate; and the cross sections of the blades are in herringbone shapes or circular arc shapes. By using the hydrodynamic electric oil fuel pump provided by the utility model, through changing the blades into the herringbone shapes or the circular arc shapes, the area of the slotted hole of the impeller is effectively increased, so that the performance of the electric oil fuel pump is improved and the service life of the electric oil fuel pump is prolonged, and meanwhile, noise is reduced.
Description
Technical field
The utility model belongs to the electric fuel punp field, is specifically related to a kind of hydrokinetic type electric fuel punp.
Background technique
Electric fuel punp is the important spare part in the fuel oil supply system, its effect is continuously the fuel oil of fuel system abundance and keeps enough pressure (pressure of oil-fired system keeps constant by pressure regulator valve), to guarantee that motor sprays effectively 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.
The hydrokinetic type electric fuel punp mainly comprises impeller, oil-feed plate and goes out oiled-plate method, is provided with a plurality of leaves hole on the impeller, oil-feed plate and go out to be provided with oil groove on the oiled-plate method, and impeller is rotated by motor driving.According to hydrokinetic principle, electric machine rotation and impeller High Rotation Speed, the impeller of rotation forms negative pressure in turnover oiled-plate method runner, fuel oil is sucked and accelerates from filler opening, the fuel oil Air is separated discharge from exhaust port simultaneously.Impeller can be transformed into pressure energy at turnover oiled-plate method runner with fuel oil speed, sets up the pressure of almost stable.The lubrication and cooling effect is played to the armature of motor, carbon brush, bearing etc. in the fuel oil fuel pump inside of flowing through simultaneously.
What early stage hydrokinetic type electric fuel punp adopted all is circumferential channel, and this pump structure is simple, low cost of manufacture, but inefficiency.In recent years, for working efficiency and the working life of improving pump, people have designed the impeller that adopts the lateral access in-line.But the useful area of this impeller is limited, and the electric fuel oil pump performance is had limitation, has hindered the raising of working efficiency.
The model utility content
The utility model provides a kind of hydrokinetic type electric fuel punp for above-mentioned the deficiencies in the prior art, good, the high working efficiency of this hydrokinetic type electric fuel oil pump performance.
The utility model is achieved by the following technical solution:
A kind of hydrokinetic type electric fuel punp comprises the pump housing, and the described pump housing comprises impeller, oil-feed plate and goes out oiled-plate method; It is characterized in that described impeller comprises circular impeller body, be provided with the slotted eye of an annular on the impeller body along its outward edge inboard, evenly be provided with a plurality of identical blades in the described slotted eye; One end of blade is towards the oil-feed plate, and the other end is towards going out oiled-plate method; The cross section of described blade is man type or circular arc.
Further setting of the present utility model is that the thickness of described blade is 3.81mm.
Further setting of the present utility model is, is provided with filler opening, oil-feed tank and exhaust port on the described oil-feed plate.
Further setting of the present utility model is, describedly goes out on the oiled-plate method to be provided with oil outlet and to go out oil groove.
Hydrokinetic type electric fuel punp described in the utility model by blade being made into man type or circular arc, has effectively increased the area of impeller slotted eye, thereby has improved electric fuel oil pump performance and life-span, and reduced simultaneously noise.
