叶轮跟高压离心通风机的工作效率有着亲密的关系，那么大家晓得我们如何改进叶轮才干上升它的工作效率吗？

The impeller has a close relationship with the working efficiency of high-pressure centrifugal fan. Do you know how to improve the impeller to improve its working efficiency?

在改进叶轮的同时，需求保证它与进风口之间的恰当间距。通常是央求新产品的宽度≤原叶轮的宽度。

While improving the impeller, it is necessary to ensure the appropriate spacing between it and the air inlet. It is usually requested that the width of the new product ≤ the width of the original impeller.

改进之后产品的构造应当保证可以顺利完成装置。普通是央求新产品的外径应不得过原叶轮的外径。而且其加工工艺性能较好，要利于各配件的加工成型及叶片与轮盘、轮盖的总装，新叶轮叶片数量少于原叶轮叶片的数目。

The structure of the improved product shall ensure the smooth completion of the device. Generally, it is required that the outer diameter of the new product should not exceed the outer diameter of the original impeller. Moreover, its processing performance is good, which should be conducive to the processing and forming of various accessories and the general assembly of blades, disc and wheel cover. The number of new impeller blades is less than that of the original impeller blades.

还要同时契合高压离心通风机运转时需求的平安系数。而且叶轮的强度和刚度等应大于原叶轮。配装新产品之后，高压离心通风机的气氛动力性能较好。此外还要留意，应实行细致的阐发、计算与理论考证，阐发以上各点央求。以保证新设计产品的保险稳定性和气氛动力机能。

At the same time, it should also meet the safety coefficient required by the operation of high-pressure centrifugal fan. Moreover, the strength and stiffness of the impeller shall be greater than that of the original impeller. After the new product is installed, the atmosphere dynamic performance of high-pressure centrifugal fan is better. In addition, we should also pay attention to the implementation of detailed analysis, calculation and theoretical research to explain the above requirements. To ensure the safety stability and atmosphere power function of the newly designed products.

另外还要保证其具有适合的旋向及各叶片与轮盘、轮盖的垂直度后，改进前产品在铆接组装时需求留意：将其两端的凸耳局部穿入轮盘、轮盖上相应的装配定位孔。盘曲叶片两头的凸耳局部，将4个凸耳分袂与轮盘、轮盖铆接严密而成。

In addition, after ensuring that it has a suitable rotation direction and the perpendicularity of each blade with the wheel disc and wheel cover, pay attention to the riveting assembly of the product before improvement: partially penetrate the lugs at both ends into the corresponding assembly positioning holes on the wheel disc and wheel cover. The four lugs are riveted tightly with the wheel disc and wheel cover respectively.
