斗式提升机常见故障的原因及排除办法大集合
斗式提升机是农产品加工厂和乡镇粮管所广泛使用的一种垂直升运设备,具有提升高度大,提升稳定,占地面积小和良好的密封性等优点。适合升运粉状、粒状和小块状物料。

现对该设备几种常见故障的原因进行分析并提出排除办法:1料斗带打滑(1)斗式提升机是利用料斗带与头轮传动轴间的摩擦力矩来进行升运物料的,叵料斗带张力不够,将导致料斗带打滑。这时,应立即停机,调节张紧装置以拉紧料斗带。若张紧装置不能使料斗带完全张紧,说明张紧装置的行程太短,应重新调节。正确的调节方法是:解开料斗带接头,使底轮上的张紧装置调至最高位置,将料斗带由提升机机头放入,穿过头轮和底轮,并首尾连接好,使料斗带处于将张紧而未张紧的状态。然后使张紧装置完全张紧。此时张紧装置的调节螺杆尚未利用的张紧行程不应小于全行程的50%。
