锅炉引风机叶片进风口端部,一旦磨漏就失去平衡,产生振动,即需更换叶轮。我厂锅炉引风机型号为Y4-73NO14D,其叶片经多年运行,使用周期均在四至六个月之间,更换频繁,造成停机检修次数多、时间长,损失很大。 为提高叶轮使用寿命,我们与风机专业人员共同研制,在叶片进风口端部加R7mm圆弧翼形16Mn圆钢补强的结构,呈流线型,如图1所示。叶
Boiler suction fan blade inlet end, once the wear and tear on the loss of balance, resulting in vibration, that is, need to replace the impeller. I plant boiler induced draft fan model Y4-73NO14D, the leaves after many years of operation, the use of cycles are in between four to six months, frequent replacement, resulting in downtime more than a few, a long time, great loss. In order to improve the service life of the impeller, we developed jointly with the wind turbine professionals. The structure of the R7mm circular arc-shaped 16Mn round steel reinforcement at the end of the air inlet of the blade was streamlined, as shown in Figure 1. leaf
