摘要:
为提高矿用防爆抽出式对旋轴流局部通风机叶轮的安全可靠性,以FBDC№9.0/2×30型通风机叶轮为研究对象,利用有限元分析软件对叶轮建立了有限元计算模型,对其应力和位移进行了计算.经测试,通风机运转平稳,无异常声响,风量为655~978 m3/min,全压为412 ~3 443Pa,静压为118 ~3 314Pa,最高静压效率达到7035%,最高全压效率达到7423%,比A声级噪声为176 dB,叶轮的强度和刚度满足要求.样机试验及现场应用表明:对该型通风机叶轮所建立的计算与分析模型正确;通过合理的设计,采用等厚圆弧板叶型、普通热轧低碳钢板材质作叶片的对旋轴流叶轮,其强度、刚度能够满足要求,整机的空气动力性能较好.
Abstract:
To improve the impeller safe reliability of extractable explosion\|proof contra\|rotating axial fan for mine local ventilation, extractable explosion\|proof contra\|rotating axial fan for mine local ventilation FBDC№9.0/2×30(impeller diameter of 0.9 m, 2 stages, single stage power of 30 KW) was taken as the research object, and an approximate three\|dimensional finite element computation model is built by using ANSYS software. The stress and the displacement were calculated, too. By testing, the fan works stably without unusual sound. The air quantity is 655-978 m3/min, total pressure is 3443-412 Pa, static pressure is 3314-118 Pa. And the highest static pressure efficiency is up to 70.35%, the highest total pressure efficiency is also up to 74.23%, a\|weight specific sound level is 17.5 dB. Furthermore, the intension and stiffness of the impeller meet requirements. Sample test and field using show that the computation and the model of this impeller are right,through reasonable design, the impeller of contra\|rotating axial fan with equally\|thick circular arc blade profile and common hot\|rolling low\|carbon steel blades has the intension and the stiffness which meet demands, and the air performance reaches higher level.
