葉輪是流體機(jī)械中的關(guān)鍵部件，廣泛應(yīng)用于泵、風(fēng)機(jī)、壓縮機(jī)和渦輪等設(shè)備中。

它由安裝在旋轉(zhuǎn)軸上的多個葉片組成，旨在通過旋轉(zhuǎn)來傳遞機(jī)械能給流體或從流體獲取機(jī)械能。

當(dāng)葉輪旋轉(zhuǎn)時，它能夠增加經(jīng)過的氣體或液體的速度和壓力，或者在渦輪的情況下，利用流體的能量來驅(qū)動機(jī)械運(yùn)動。

The impeller is a critical component in fluid machinery, widely utilized in devices such as pumps, fans, compressors, and turbines. 

It comprises multiple blades mounted on a rotating shaft, designed to transfer mechanical energy to a fluid or extract energy from it through rotation. 

When the impeller rotates, it can increase the speed and pressure of the passing gas or liquid, or in the case of a turbine, use the energy of the fluid to drive mechanical motion.
