多級離心型鼓風(fēng)機：多級離心鼓風(fēng)機和單級的區別

2020-11-13

概要

單級和多級離心型鼓風(fēng)機是一種調速風(fēng)扇，也就是說(shuō)，在工作輪旋轉期間，由于旋轉離心力和工作輪中的擴散流的作用，氣體的速度增加，然后使用擴散器將速度能量轉換為壓力能量。兩者之間的具體區別是：

多級離心型鼓風(fēng)機

單級和多級離心型鼓風(fēng)機是一種調速風(fēng)扇，也就是說(shuō)，在工作輪旋轉期間，由于旋轉離心力和工作輪中的擴散流的作用，氣體的速度增加，然后使用擴散器將速度能量轉換為壓力能量。兩者之間的具體區別是：

單級離心風(fēng)機只有一組葉輪，一次完成了空氣壓縮，而多級離心型鼓風(fēng)機的主軸上有多組葉輪，并且在各組之間逐漸完成了空氣壓縮。由于離心風(fēng)機依靠提高空氣流速，即依靠空氣動(dòng)能來(lái)壓縮空氣以增加壓力，以獲得相同的壓力，因此單級離心風(fēng)機的葉輪需要高幾十倍。通常情況下多級風(fēng)機的轉速只有數千轉，而單級風(fēng)機的轉速卻高達數萬(wàn)轉甚至高達數十萬(wàn)轉。

由于壓力的供應很大程度上取決于速度的提高，并且速度的供應受到平衡，潤滑和材料性能的限制，因此，單級離心風(fēng)機在低壓情況下使用較多，而在高壓情況下則更多使用多級離心型鼓風(fēng)機。

由于單級離心風(fēng)扇更多地依賴(lài)齒輪箱來(lái)獲得高速，因此風(fēng)扇的維護特別麻煩。必須同時(shí)提供單獨的潤滑油。同時(shí)，由于葉片和其他零件的高速運轉，使用多級離心型鼓風(fēng)機的使用壽命要優(yōu)于單級鼓風(fēng)機。
