我厂常压装置自1985年配减压系统后,减顶油气采用湿式宅气冷却器冷却。但是该系统投用以来,减顶1~#、2~#风机联组皮带失效造成过早报废,成了长期没有解决的问题。为此,我们对减顶1~#、2~#风机联组皮带失效原因进行了如下分析,并采取了相应措施。用专用测量塞规检查带轮,发现小轮槽深度不够,从而使原有的V带传动变成了平皮带传动(靠V带底部摩擦传动),在这种情况下,联组皮带的摩擦力下降,V带打滑,带轮温度升高(约80～90℃),V带拉伸,帘布层损坏脱落,V带顶部损坏,最后铰断报废。
I plant atmospheric pressure device with a decompression system since 1985, the cap down by the wet gas-air cooler cooler. However, the system has been put into use, reducing the top 1 ~ #, 2 ~ # fan combination of belt failure caused by premature retirement, has become a long-term problem has not been solved. To this end, we cut down on the 1 ~ #, 2 ~ # fan combined belt failure causes the following analysis, and take corresponding measures. Check the pulley with a special measuring plug gauge and found that the depth of the small wheel groove is not enough, so that the original V belt drive into a flat belt drive (by the V-belt friction drive), in this case, the joint friction belt V-belt slippery, pulleys temperature rise (about 80 ~ 90 ℃), V-belt tension, ply damage off, V-belt top damage, the final hinge off scrapped.
