风机导流鼻的应用.doc

装卸时风机导流鼻的应用 风机转子是整台风机的心脏部件,转子运转正常与否将直接影响到整台装置的可靠性;转子由带动叶片的叶轮、动叶机械式调节机构、整体式轴承箱和刚扰性联轴器等部件组成。 Fan rotor is the heart of the whole turbine parts, rotor is working well or not will directly affect the reliability of the device; Rotor by the impeller and the rotor blades of the driving mechanical adjusting mechanism, the integral bearing box and just one shaft coupling and other parts. 叶轮与主轴采用过盈带键配合,装卸时用专用的液压装拆工具拆装,为适应风机变工况运行和矿井反风要求,叶轮壳内装有一套机械式调节机构,该套机构包括调节杆、调节轴、铰链联轴器、蜗轮箱中心圆直齿轮、大锥齿轮、及轴承等,当需要调节动叶角度时,将调节杆放在调节轴上,然后旋转,使叶柄旋转调节直要求的动片角度。 Impeller with spindle by interference with the key, when loading and unloading in the special hydraulic tool installation, dismantling, fan variable working conditions and to adapt to the mine air against requirements, within the impeller shell has a mechanical adjusting mechanism, the set of institutions, including adjusting rod, adjust the hinge shaft, coupling, central circle spur gear, bevel gear, worm gear box and bearing, etc., when need to adjust the moving blade Angle, put the regulating rod on the regulating shaft, then spin, spin the petiole straight requirements of dynamic Angle adjustment. 风机轴承箱轴承稀油池侵入式润滑,当轴承转速较高时,外置油站强制循环,轴承温度有8只电阻温度计监视;为减少气流在弯道中的气流损失,并使气流均匀流入垂直扩压器,在弯道内设有导流叶片和导流鼻;为了使风机的振动不传至进排气管道和维修时拆卸方便,机壳与整流环、扩散器之间采用围带扰性连接。 Invasive fan bearing box bearing thin oil pool lubrication, when bearing at high speed, the outer station forced circulation, bearing temperature have eight resistance thermometer monitoring; For reducing the loss of air flow in the corner, and make the air flow evenly into the vertical diffuser, the curves with guide vane and diversion nose; In order to make the vibration of the fan does not spread to the exhaust pipe and maintenance convenient disassembly, chassis and rectifying ring, between diffuser USES surrounded with one sex. 基础不拆除,地脚螺栓不能用,必须将螺栓拆除,再浇注上新螺栓,才能安装新通风机,经研究利用钻机在原来基础的螺栓上打孔,钻头直径为120mm,将地脚螺栓掏出,再预浇注新螺栓,这样泰安锅炉就不用拆除通风机基础,只更换通风机的地脚螺栓,矿井不用停产就可以更换风机。 Based not dismantle, anchor bolt ca
