Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] In this embodiment, an energy-saving centrifugal impeller includes: a wheel body 100 , a first guide vane 200 , and a second guide vane 300 . In this embodiment, the wheel body 100 , the first guide vane 200 , and the second guide vane 300 are integrally formed.

[0019] The wheel body 100 has a central cylinder 110 and a chassis 120 . The first guide vanes 200 are uniformly distributed on the wheel body 100 , the inner side of the first guide vanes 200 is attached to the center cylinder 110 , and the bottom of the first guide vanes 200 is attached to the chassis 120 . Such as figure 1 As shown, a first guide cavity is formed between two adjacent first guide vanes 200 . The outer profile 200a of the first guide vane 200 is formed by two tangent circular arcs, which is an "S" shape. Such as figure 2 The illustrated first guide vane ...

Abstract

The invention provides an energy-saving centrifugal impeller. The energy-saving centrifugal impeller comprises a wheel disc body, first flow-guiding vanes and second flow-guiding vanes; the wheel discbody is provided with a central column and a chassis; the first flow-guiding vanes and the second flow-guiding vanes are uniformly arranged on the wheel disc body in a circumference mode, the secondflow-guiding vanes are arranged between the every two adjacent first flow-guiding vanes; the height of each first flow-guiding vane is greater than the height of each second flow-guiding vane; the first flow-guiding vanes are composed of first inlet sections, first flow dividing sections and first outlet sections; the second flow-guiding vanes are composed of second flow dividing sections and second outlet sections. The energy-saving centrifugal impeller has the advantage that front sections of the first vanes introduce the airflow into the impeller, the impact loss of the airflow is reduced,the second vanes are additionally arranged at the middle section to shrink a flow path, enhance the supercharging effect and reduce the air inlet resistance; two vane outlet structures are same, and the high-speed airflow is evenly diffused, so that the impeller rotates smoothly, the impeller rotating inertia is improved, and the overall efficiency of supercharging is improved.

Description

technical field [0001] The invention discloses an energy-saving centrifugal impeller. Background technique [0002] A centrifugal compressor is a component that uses a high-speed rotating centrifugal impeller to drive the blades on the impeller to rotate at a high speed and work on the air to increase the air pressure. In the existing technology, the loss of the air entering the inlet of the impeller is large, and the moment of inertia of the impeller is large, which will lead to disadvantages such as long start-up acceleration time and large torsional vibration, thus making the increase effect not good. Generally, the speed of rotation is increased, that is, the energy consumption of greater power can be used to obtain the required supercharging effect. Contents of the invention [0003] The problem to be solved by the present invention is to provide an energy-saving centrifugal impeller. The front section of the first blade guides the airflow into the impeller to reduce...
