由清华大学和北京风机厂研制成的10-19型鼓风机,其压头系数接近一,全压效率达88％左右,用于小氮肥厂造气,效果显著。 该风机具有下列优点:1.效率高。比小氮肥厂原用8-18.8串联风机提高21～25％左右,且可省去一台串联机,节电显著。2.改装方便、费用少。安装时可利用原8-18.8风 The 10-19 blower, developed by Tsinghua University and Beijing Fan Factory, has an indenter coefficient close to one and an all-pressure efficiency of about 88%. It is used for making gas in small nitrogenous fertilizer plants, and the effect is remarkable. The fan has the following advantages: 1. High efficiency. Than the original small-scale nitrogen fertilizer 8-18.8 series fan increased 21 ~ 25%, and can save a tandem machine, saving significant. 2. Easy modification, low cost. The original 8-18.8 wind can be used when installing
