随着矿井开采深度、开采范围的逐渐加大,矿井通风难度也愈来愈大,同时,随采掘机械化程度的不断提高,长距离通风逐渐被众多的人们所接受,对局部通风设备以及作为主要防护装置的消音器提出了较高的要求,而目前正处于老产品仍在超期使用,新产品急待开发,在新老交替过程当中。我们曾对JBT系列风机,对旋式局部消音扇风机、塑料质局扇以及玻璃钢消音器进行了全面的技术性能测试,并进行多方面的综合比较,体会颇深,现将这方面的体会浅谈如下。 With the mining depth, the mining range gradually increased, mine ventilation is also increasingly difficult, at the same time, with the mining mechanization degree continues to improve, long-distance ventilation gradually accepted by many people, the local ventilation equipment and as a major Muffler protection devices put forward higher requirements, and is currently in the old product is still in use over time, the urgent need to develop new products, in the process of replacement of old and new. We have carried out a comprehensive technical performance test of JBT series fans, counter-rotating local silencers fan, plastic quality fan and fiberglass silencer, and conducted comprehensive comparison of various aspects, deeply understand, and now experience shallow in this regard Talked about as follows.
