Because of swing of the radial labyrinth wreath with the shaft in main sintering fan, lead to the oil leakage problem of the bearing seat in LAIGANG sintering plant. 莱钢烧结厂烧结主抽风机原采用离心式迷宫密封,因离心密封环随轴向窜动引起轴承座漏油。
Investigation of Radial Distortion in the Axial-flow Fan by Di-actuator Theory 基于双激盘理论的轴流风机径向畸变研究
To obtain good aerodynamic characteristics, the radial aerodynamic balance equations were adopted to build the fan's rotating blades, which were evolved from the simplified three dimensional flow theories, the constraint conditions and the control vortex theory. 采用简化的三元流动设计理论得到叶轮叶片气动设计径向平衡方程式和求解约束条件,进而引入了控制涡设计理论进行风扇叶片造型,获得了优良的气动性能;
In this paper, the inner fluctuation flow field and the regularities of the change of flow feild parameters are calculated in the radial direction of the impeller of a centrifugal fan. 本文定量计算了离心式风机叶轮径向面上内部脉动流场的分布以及流场参数的变化规律。

The factor affecting bearing internal radial clearance, the relationship between clearance and operating life time and fan failure process were discussed. 讨论了影响轴承游隙的因素和轴承游隙与轴承寿命的关系,并对轴承游隙过小而导致整个风机损坏的逻辑过程进行了推理。
Due to the strong axial and radial load to the bearing of electromotor in counter-rotating axial fan, it is always occurred that the bearing was damaged in use. 由于对旋轴流式风机电动机轴承要承受较大的轴向负荷和径向负荷,实际使用过程中常发生电动机轴承损坏的现象。
Using the streamline curvature method and the full radial equilibrium equations, the duct flow calculations of an axial_flow fan are presented in this paper. 采用流线曲率法,计算完全径向平衡方程,求出轴流通风机轴向间隙的气流分布。
At the same time by changing the CAD model of radial clearance, the different radial clearances of the axial flow fan are compared for the Fan performance optimization. 同时通过改变CAD模型中的径向间隙,对不同径向间隙的轴流通风机流场进行对比,得到了优化的风机设计。
The performance influence of sinking degree and radial clearance change of the cooling fan and the auxiliary member and the commonly used top ring structure in the arc bending plate fan are analyzed. 在风扇风室模型内对冷却风扇与辅助部件的沉入量和径向间隙变化对性能影响进行了分析,并将圆弧弯板风扇常用的顶环结构对风扇性能影响进行了仿真分析。
Then if radial clearance of an Axial Fan is not appropriate, the fan will not only reduce the efficiency and performance, but also an additional increase in the fan noise, shorten the life of Fan. 因此如果叶片尖端与外壳的间隙不恰当,不仅会降低通风机的效率与性能,还会额外地增加通风机的噪声,缩短通风机的使用寿命。
