排烟风机主轴断裂的原因有哪些?

发布时间:2019/07/16

  在烟火灾排烟风扇是一种常见的风扇与高质量的产品,超高的性能赢得了客户的普遍认可,但如果我们通常使用不当,可能会导致火灾排烟风机主轴弯曲断裂现象,甚至我们分析应该是以下三个原因:
  In smoke and fire exhaust fan is a common fan and high-quality product. Super-high performance has won the general recognition of customers. But if we use it improperly, it may lead to the bending fracture of the main shaft of the smoke exhaust fan. Even our analysis should be based on the following three reasons:
  1. 叶轮磨削或叶片结垢严重,导致叶轮失去平衡,产生离心惯性力。在离心力的作用下,产生剧烈的振动。
  1. Impeller grinding or blade scaling is serious, which causes impeller unbalance and centrifugal inertia force. Under the action of centrifugal force, it produces violent vibration.
  2. 维修时排烟风机箱与电机安装不对齐。排烟风机箱与电机两轴通过联轴器连接时,轴向偏差和径向偏差过大,使整机产生较大的振动,使轴变形。
  2. Installation of smoke exhaust fan box and motor is not aligned during maintenance. When the two axes of exhaust fan box and motor are connected by coupling, the axial and radial deviations are too large, which makes the whole machine produce greater vibration and makes the shaft deform.
  3.工作轴滚动轴承磨损严重,间隙过大时振动剧烈,产生较大的弯曲应力,导致轴弯曲变形。
  3. Work shaft rolling bearings are worn seriously, and when the clearance is too large, the vibration is intense, resulting in greater bending stress, which leads to the bending deformation of the shaft.
  双速排风机安装风扇,或用手杆拉移动叶轮,消防排烟风机检查是否有一个紧密的擦碰现象,任何妨碍旋转对象,没有异常现象,可以测试运行,风应该暴露部分的机会驱动盾(用户应该带上自己的)。如风机进气口不收线,还需购置护栏或其他安全装置(用户应自备)。
  Dual-speed exhaust fan installs fan, or pulls impeller by hand. Fire exhaust fan checks whether there is a close rubbing phenomenon. Any obstacle to rotating object, no abnormal phenomenon, can be tested and run. Wind should expose part of the opportunity to drive shield (users should bring their own). If the air inlet of the fan is not closed, guardrail or other safety devices should be purchased.
  风机接线必须正确可靠,风机外壳接地必须正确,接地必须可靠。
  The connection of the fan must be correct and reliable, the grounding of the fan shell must be correct, and the grounding must be reliable.

  消防排烟风机性能非常突出,并已广泛使用,大多数用户喜爱,和消防排烟风机应用也相对强劲,在电压不稳定的情况下也可以应用,排烟风机,但我们必须合理地操作它,只有这样才能成功完成的任务排烟。
  Fire exhaust fan performance is very outstanding, and has been widely used, most users like, and fire exhaust fan application is relatively strong, in the case of voltage instability can also be applied, smoke exhaust fan, but we must operate it reasonably, only in this way can successfully complete the task of smoke exhaust.
  我们都知道火灾排烟风机主要是在中温100℃条件下连续工作20小时/次不损坏的情况下,3℃火灾高温风机、高层建筑、地下建筑及隧道、干燥室通风或高温烟气等。火灾排烟风机的主要参数是工作温度、风量、噪声、总压和效率、电力、转速和轴功率。
  We all know that fire exhaust fans mainly work for 20 hours at medium temperature of 100 (?) C continuously without damage. Fire exhaust fans at 3 (?) C, high-rise buildings, underground buildings and tunnels, ventilation in drying rooms or high-temperature smoke, etc. The main parameters of fire exhaust fan are working temperature, air volume, noise, total pressure and efficiency, power, speed and shaft power.

  高温消防排烟风机主要适用于高层建筑、地下建筑、隧道、烘干室通风或高温烟,等工作条件下的280℃高温超过30分钟后,介质温度100℃,消防排烟风机主要是生产和运行的环境,我们必须根据它的合理利用,因此它的性能充分发挥。
  High temperature smoke exhaust fan is mainly suitable for high-rise buildings, underground buildings, tunnels, drying room ventilation or high temperature smoke. When the temperature exceeds 30 minutes at 280 C under working conditions, the medium temperature is 100 C. Fire exhaust fan is mainly the production and operation environment. We must make full use of its performance according to its reasonable utilization.
  现在我们知道了火灾排风机致命损坏的原因,在使用过程中要注意这些要点,确保风机能够正常工作,发挥应有的作用。
  Now we know the cause of fatal damage of fire exhaust fans. We should pay attention to these points in the use process to ensure that the fans can work normally and play their due role.
