5、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; Fo
6、r 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, be
7、tween 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 cant use, must remove the bolt, then pouring new bolts, to install the new fan, studies usin
8、g drill bolt holes in the original basis, drill bit diameter is 120 mm, the anchor bolt pulled out, precast new bolts again, so you dont have to dismantle the ventilator, replace the fan only anchor bolt, mine dont have to stop production to replace the fan. 调节杆仅在停机后调节叶片时使用,用完后必须从风机上拿下,关闭调节视孔盖和调节操纵杆
9、插入孔盖,才能启动风机;动叶片采用高强度铸铝合金,叶片的叶盘与叶http:/ http:/ http:/ http:/ 柄法兰采用特制高强度螺钉连接,并用螺钉套作为抗咬垫圈,为确保叶柄转动灵活,防止锈蚀咬死和灰尘进入堵塞,在叶柄法兰与轮壳孔的装配部位采用含石墨的迷宫密封型铸铜轴衬和弹性密封圈,叶柄轴衬与叶柄法兰滑动配合,具有支持轴承的作用。Regulating rod only adjust the blade after downtime when use, after use must win from fan, closed hole cover vision and regulatin
10、g lever to insert the hole cover, in order to start the fan; Rotor blade high strength casting aluminum alloy, blade semal and petioles flange connected by special high strength bolts, and screw set as an bite washers, in order to ensure the petioles flexible rotation, to prevent rust killed and dus
11、t into the congestion, the petiole wheel flange and shell hole assembly parts adopt labyrinth type containing graphite cast copper bushing and elastic sealing ring, petiole bushing with petioles flange sliding fit, have the function of the support bearings. 机壳是风机的主要部件之一,转子、油管路系统等重要部件均安装在机壳内,机壳有内筒、外筒
12、、后导叶及轴承箱支承环等组成,机壳采用水平剖分结构,上下半机壳在中分面法兰上用四个定位锥螺栓及螺栓联结,此种结构便于安装和维修; 行吊机壳内外筒后导叶焊接连结,其中一片是空心导叶通过它将轴承箱的进排油气管、温度计导线引出机壳外;为防止动叶与机壳内壁碰擦,产生火花,在机壳内壁动叶片相对位置设置了铜衬板。Chassis is one of the main components of the fan rotor, pipe line systems and other important components are installed inside the casing, casing inne
13、r tube, outer tube, after the guide blade and bearing box and other components of the bearing ring, casing by adopting the structure, the level of upper and lower half casing on the split flange with four cone bolt positioning and bolt connection, this structure is convenient for installation and ma
14、intenance; Casing inside and outside the cylinder vane after welding, which is a hollow guide blade by bearing box it will air into the oil discharge pipe and the thermometer outside the wire lead to casing; To prevent moving blade and casing inner surface scratches, produce sparks, on the inner wall of the casing, copper plate is set by the relative location of rotor blade.
