Hole and fuel feed hole, described axle installing hole matches with the installation axle of described driving gear.Install in one end of described driving gear
Described receded disk impeller, utilizes described driving gear to rotate, drives and rotate for described receded disk impeller, meanwhile, described centrifugal
Formula impeller is arranged at described inlet port, causes the flow direction of fluid to change into from impeller axial direction from being directly entered gear cavity
Top enters inside described receded disk impeller so that described receded disk impeller can drive fluid to rotate, and improves fluid speed.Institute
The effect stating dividing plate is to be separated with described spiral case in pump housing chamber, can more ensure that fluid has enough speed and pressure to enter into oil suction
At chamber.
Described spiral case is formed with small cylindrical tank and accommodates the big circular groove of described receded disk impeller, described small cylindrical tank and described great circle
Groove is connected by the square groove being opened on described spiral case.Described receded disk impeller is arranged in described spiral case pipeline, described spiral case
The effect of pipeline is to ensure that in the case of described receded disk impeller rotates, it is possible to increase the speed of fluid and pressure.
Also include conical pipeline, seal with described fuel feed hole at the portlet of described conical pipeline and coordinate, described conical pipe
It is meshed with described driven gear place near described driving gear at the large port in road.Described conical pipeline, described dividing plate and institute
Stating spiral case and form the runner of fluid, fluid enters from described inlet port, through above-mentioned runner, flows at oil sucting cavity.
The diameter of described axle installing hole is not more than the diameter of described big circular groove cross section.Fully ensure that dividing plate just pump housing chamber
Separate with described spiral case, do not have the fluid described great circle groove in described spiral case to be flowed into pump housing intracavity.
It can be gear shaft that described driving gear installs axle with it.
Described receded disk impeller is directly fixedly mounted on gear shaft, it is not necessary to other structure and the support of parts, outward
Portion's prime mover drives described gear shaft to rotate, and described gear shaft can drive described receded disk impeller to rotate simultaneously.
When described driving gear rotates, driving gear described at oil sucting cavity and described driven gear are disengaged, and make
Sealed volume increases, and forms parital vacuum, and the fluid in fuel tank, under the effect of external atmosphere pressure, when high-speed gear rotates, causes
Making fluid can not be completely filled with between cog, described fluid is by the receded disk impeller rotated, and passes through by described spiral case, described dividing plate
Form liquid flow channel for oil with described conical pipeline, fluid delivered at oil sucting cavity, improve fluid and deliver to the pressure of region of no pressure so that
Gear pump still is able to ensure that fluid is full of between cog under high speed rotating.
A kind of new structure gear pump that this utility model provides, utilize driving gear rotarily drives receded disk impeller,
And through being formed the liquid flow channel for oil fluid supercharging to gear pump import by spiral case, dividing plate and conical pipeline, by tooth is greatly improved
The pressure of wheel import fluid, overcomes the problem that gear pump fluid at high speed can not be completely filled with between cog.
