KZS№21型矿井轴流式通风机是吉林市鼓风机厂在消化吸收先进水平样机基础上研制的新产品,在北京矿务局门头沟矿横岭风井经长时间运转后性能良好,于1992年12月5日至7日在现场通过了工业性鉴定,该型风机具有如下主要特点:1.产品设计合理,动叶结构新颖,可在机壳观察孔外用手调节角度,操作灵活,省时省力,强度高,运转安全可靠。全部静叶可无极动态调节,便于动、静叶匹配和对静叶进行微调,满足矿井通风参数要求,提高风机效率、达到节能目的。2.该机还可用不同转速和减少动叶片数量方
KZS№21 mine axial fan is a new product developed by Jilin Blower Factory on the basis of digestion and absorption of advanced level prototypes. After being operated for a long time at Hengtou well in Mentougou Mine of Beijing Mining Bureau, performance was good. In 1992 December 5 to 7 in the field through the industrial appraisal, the fan has the following main features: 1. Product design is reasonable, moving the blade structure of the novel, can be observed in the casing outside the hole angle adjustment, flexible operation, time-saving Effortless, high strength, safe and reliable operation. All static vanes can be dynamically adjusted without polarity, which is convenient for dynamic and static vane matching and fine adjustment of static vanes to meet the requirements of mine ventilation parameters and improve fan efficiency so as to save energy. 2. The machine can also use different speed and reduce the number of moving blades
