如何控制斗式提升机的提升速度

编辑:淄博元丰机械制造有限公司时间:2020-01-11

  斗式提升机制动时,通过切断三相异步电动机定子交流,加上上述二次直流电流进行能耗制动。斗式提升机采用一系列均匀固定在无极牵引部件上的料斗,垂直提升物料连续输送机械。斗式提升机采用固定在牵引链或皮带上的一系列料斗,将散料垂直或近垂直运输。分为环链、板链和皮带。适用于从低到高的升降。供料经振动台送入料斗后,机器自动连续向上移动。斗式提升机适用于从低处提升到高处。供料经振动台送入料斗后,机器自动连续运转向上输送。可根据输送能力调整输送速度,根据需要选择提升高度。料斗由我公司自行设计制造。这种电梯对材料的类型和特性没有什么要求。它不仅可以改善普通粉末和小颗粒材料,而且可以改善易磨性高、密封性能好、环境污染小的材料。为了满足提升机减速段的减速要求,需要采用双闭环调速方案。速度由给定的积分器给出。给定积分器输出电压的变化率对应于斗式提升机的减速。提升容器达到减速点后,取下定子高压电源。制动动力接触器关闭,辅助触点闭合。
