Abstract

The utility model provides a pump impeller comprising a cover plate, front blades and back blades, wherein a connecting part is arranged at the middle part of the cover plate, the light pump impeller is installed on a power output shaft of an engine through the connecting part on the cover plate, at least three front blades are arranged on the front end face of the cover plate at equal angles, at least three back blades are arranged on the back end face of the cover plate in equal angles, the cover plate, the front blades and the back blades form an entirety, the front blade comprises a front end part of blade and a back end part of blade, the back end part of blade is bent counterclockwise, and the front end part of blade and the back end part of blade form an included angle. The pump impeller provided by the utility model improves the current impeller structure so that a dewatering pump can achieve a high lift through a single impeller,; therefore, the impeller disclosed by the utility model can be directly used without being installed on the power output shaft of the engine through a shaft coupler, and the structure of a centrifugal pump is greatly simplified as a result.

Description

Impeller of pump

Technical field

The utility model relates to centrifugal pump fitting field, particularly impeller of pump.

Background technique

Water pump is before work, and the pump housing and intake pipe must jar full waters, relies on the impeller of high speed rotating afterwards; Can improve pressure in it thereby make liquid under the inertial centrifugal force effect, obtain energy, when the impeller quick rotation, blade impels water to rotate very soon; The water that is rotating flies to from impeller under action of centrifugal force, and after the water in the pump was dished out, the core of impeller formed vacuum area; The water at water source is pressed onto in the intake pipe through pipe network under the effect of atmospheric pressure (or hydraulic pressure) afterwards, and circulation endlessly just can realize continuous pumpage like this; Because the advantages such as conveying that it has is simple in structure, processing ease, flow are easy to regulate and be applicable to various special nature materials,, often at present adopt multistage centrifugal pump as shown in Figure 1 to draw water in order to reach certain effect of drawing water; So just need a plurality of impellers to be rotated; Therefore need coupling that a plurality of impellers are connected, thereby strengthened the complex structure degree of whole centrifugal pump greatly, make centrifugal pump not portable.

The model utility content

To above problem, the utility model improves existing blade wheel structure through the design impeller of pump; Therefore make draining pump adopt single impeller can reach very high-lift, use the said impeller of this patent to need not directly to use on the pto that coupling is installed in motor, thereby can simplify centrifugal pump structure greatly; For reaching this purpose, the utility model provides impeller of pump, comprises cover plate, front vane and rear blade; Joint is arranged in the middle of the said cover plate; Said light impeller of pump is installed in through the joint on the cover plate on the pto of motor, and the front-end face equal angles of said cover plate is provided with at least 3 front vanes, and the ear end face equal angles of cover plate is provided with at least 3 rear blades; Said cover plate and front vane, rear blade are integrally formed; Said front vane comprises blade front end and blade rearward end, and said blade rearward end is along bending counterclockwise, and blade front end and blade rearward end have angle; Angle is 90 °-175 ° between said blade front end and the blade rearward end, adopts circular arc to be connected between said front vane blade front end and the blade rearward end.

The utility model improves existing blade wheel structure through the design impeller of pump, utilizes the indoor current of front vane slosh pump of bending; Thereby can make the liquid in the pump chamber produce the spiral flow that flows to the rotation of pump protecgulum direction; Thereby the flow in the impeller front vane space is boosted, and it is higher that the centrifugal pump that make to adopt the said impeller of this patent and centrifugal pump at the same level are compared boost capability, thereby make pump discharge pressure higher; More stable; Therefore adopt single impeller can reach very high-lift, therefore use the said impeller of this patent to need not directly to use on the pto that coupling is installed in motor, thereby can simplify centrifugal pump structure greatly; Make centrifugal pump structure more light, be easier to use.

Embodiment

Below in conjunction with accompanying drawing and embodiment model utility is done detailed explanation:

The utility model is through the design impeller of pump; Existing blade wheel structure is improved; Make draining pump adopt single impeller can reach very high-lift; Therefore use the said impeller of this patent to need not directly to use on the pto that coupling is installed in motor, thereby can simplify centrifugal pump structure greatly.

As a kind of specific embodiment of the utility model, the utility model provides structural representation impeller of pump as shown in Figure 2, comprises cover plate 1, front vane 2 and rear blade 3; In the middle of the said cover plate 1 joint 1-1 is arranged; Said light impeller of pump is installed on the pto of motor through the joint 1-1 on the cover plate 1, because it is higher make to adopt centrifugal pump and the centrifugal pump at the same level of the said impeller of this patent compare boost capability, pump discharge pressure is higher; More stable; Therefore adopt single impeller can reach the lift of traditional multi-stage impeller, therefore use the said impeller of this patent to need not can directly use on the pto that coupling is installed in motor, the front-end face equal angles of said cover plate 1 is provided with 4 front vanes 2; The ear end face equal angles of cover plate 1 is provided with 6 rear blades 3; Said cover plate 1 is integrally formed with front vane 2, rear blade 3, and this external impeller increases rear blade 3 at the back, can make pressure balance as far as possible in the pump chamber; Thereby can improve the working life of sealing greatly; Said front vane 2 comprises blade front end 2-1 and blade rearward end 2-2, and said blade rearward end 2-2 is along bending counterclockwise, and blade front end 2-1 and blade rearward end 2-2 have angle; Angle is 90 °-175 ° between said blade front end 2-1 and the blade rearward end 2-2; This patent blade front end 2-1 and blade rearward end 2-2 can adopt any angle in 90 °-175 °, and the effect and the design difficulty that adopt the different amount impeller to be produced are all different, and producer can reach the manufacturing degree of difficulty as the case may be and select; Adopt circular arc to be connected between said front vane blade front end 2-1 and the blade rearward end 2-2, effect thereby the resistance raising that can significantly reduce current is drawn water.

The indoor current of front vane 2 slosh pump of the utility model utilization bending; Thereby can make the liquid in the pump chamber produce the spiral flow that flows to the rotation of pump protecgulum direction, thereby the flow impeller front vane 2 spaces in is boosted, thus the centrifugal pump that adopts the said impeller of this patent and centrifugal pump at the same level to compare boost capability higher; Pump discharge pressure is higher; More stable, be a plurality of impellers of alternative multistage draining pump with the said impeller of single this patent, thereby can simplify centrifugal pump structure greatly; Make centrifugal pump structure more light, be easier to use.

The above; It only is the preferred embodiment of the utility model; Be not to be the utility model to be done the restriction of any other form, and, still belong to the utility model scope required for protection according to any modification or equivalent variations that the technical spirit of the utility model is done.
