Abstract
The utility model discloses a water pump impeller with vanes on the back, comprising an axel hole (3), a hub (1) and homo-axial bent vanes (2) connected with the hub (1). The axel hole is connected with a pump body by a bearing, and the back of each of the vanes is provided with a guide vane (4). The guide vane (4) can guide water to the axel hole when the impeller rotates at high speed. Because the back of the vane of the centrifugal impeller is provided with the guide vane, and part of the water rotated around the outer circumference of the impeller by the centrifugal force flows to the axle hole of the impeller by the action of the guide vanes during the high speed operation of the impeller, and the water can cool the bonding part of the axle hole and the bearing in order to ensure the consistency of the expansion caused by heat and the contraction caused by cold of the entire impeller, and promote the normal operation of the impeller and prolong the service life of the impeller.
Description
Technical field
The utility model belongs to centrifugal pump component technology field, the water pump vane of the attached blade profile of particularly a kind of back side band.
Background technique
Conventional centrifugal pump impeller comprises axis hole, wheel hub and be connected the blade of wheel hub, described blade is the smooth surface of certain radian, in the process of impeller high speed rotating, water around the water pump vane flows fast to water supply direction on the one hand, can produce centrifugal phenomenon with the rotation of blade on the other hand, this just causes has only a spot of water that the axis hole position is lowered the temperature near impeller shaft, even in some high-speed water, impeller axis hole heating position does not just have water at all, this just is easy to generate the heating phenomenon of axial region, because impeller itself is different with the closeness of contact of water, be easy to produce phenomenon uneven in temperature, the high temperature deformation of axial region can destroy the overall structure of its impeller, even it is burnt out.
The model utility content
The utility model provides a kind of impeller that can also carry out water-cooled when the impeller high speed rotating to the axis hole position.
The water pump vane of the attached blade profile of a kind of back side band comprises axis hole, wheel hub and is connected the blade of the same circumferential skewing of wheel hub that the back of described blade also is provided with a guide vane, and described guide vane can be with the water water conservancy diversion to the axis hole position when the impeller high speed rotating.
Because the back of the water pump vane blade of the attached blade profile of the utility model back side band is provided with guide vane, can make impeller in the process that runs up, part is rotated near the impeller outer circumference water because the effect of guide vane flows near the axis hole of impeller because of centrifugal action, can closely cool off axis hole and bearing binding site, guarantee the conformity that impeller integral body is expanded with heat and contract with cold, promote its normal operation of impeller, the life-span of improving impeller.
Description of drawings
The utility model is further described below in conjunction with accompanying drawing:
Fig. 1 is the plan view of the water pump vane of the attached blade profile of the utility model back side band.
Fig. 2 is the right elevation of the water pump vane of the attached blade profile of the utility model back side band.
Embodiment
As shown in Figure 1 and Figure 2, the water pump vane of the attached blade profile of the utility model a kind of back side band, comprise axis hole 3, wheel hub 1 and be connected the blade 2 of the same circumferential skewing of wheel hub 1, axis hole 3 is connected on the pump housing by bearing, the back of described blade 2 also is provided with a guide vane 4, and described guide vane 4 can be with the water water conservancy diversion to axis hole 3 positions when the impeller high speed rotating.
Because the back of the water pump vane blade of the attached blade profile of the utility model back side band is provided with guide vane, can make impeller in the process that runs up, part is rotated near the impeller outer circumference water because the effect of guide vane flows near the axis hole of impeller because of centrifugal action, can closely cool off axis hole and bearing binding site, guarantee the conformity that impeller integral body is expanded with heat and contract with cold, promote its normal operation of impeller, the life-span of improving impeller.
Claims (1)
1. the water pump vane of the attached blade profile of back side band, comprise axis hole (3), wheel hub (1) and be connected the blade (2) of the same circumferential skewing of wheel hub (1), axis hole (3) is connected on the pump housing by bearing, it is characterized in that: the back of described blade (2) also is provided with a guide vane (4), and described guide vane (4) can be with the water water conservancy diversion to axis hole (3) position when the impeller high speed rotating.
