广东韶关冶金机械厂根据国务院2号节能指令精神,为改变目前金属矿山使用的效率低、噪音高、体积大、笨重的老型号风机(JF及JBT系列),与武汉华中工学院压缩机教研室共同研制成功GKJ系列高效低噪声节能轴流通风机新产品。其优点是: 1.该风机是按准三元流理论设计的子午加速式风机,与目前国内生产的同类型局部通风机相比具有效率高、噪音低、体积小、重量轻、高效区宽、性能调节范围大等优点。 2.较老产品(JF及JBT系列)效率平均提高25％以上。以GKJ67—Z450型风机(7.5KW)为例,如
Guangdong Shaoguan Metallurgical Machinery Factory In accordance with State Council’s Energy Saving Directive No. 2, in order to change the low efficiency, high noise, bulky and cumbersome old-style fans (JF and JBT series) used in metal mines at present, it cooperates with Wuhan Huazhong Institute of Technology compressor department The successful development of GKJ series of high-efficiency low-noise energy-saving axial fan new products. The advantages are: 1. The fan is a quasi-ternary flow theory design of radial accelerator fan, with the current domestic production of the same type of local fan compared with high efficiency, low noise, small size, light weight, high efficiency wide , Performance adjustment range and so on. 2. The older products (JF and JBT series) have an average efficiency of more than 25%. Take GKJ67-Z450 fan (7.5KW) as an example
