1 前言中板厂旋流沉淀池距地面较深,在地面观察水位有一定困难,然而水位高低对生产影响较大,太高不利于轧机排水,太低则使水泵工作处于不正常状态,影响水泵使用寿命。基于这种情况,我们设计了一套水位报警装置,经现场使用,对操作工及时操作起到了很好的作用。 2 工作原理如图1所示,重力为G的空心球与重力为g的平衡锤分挂在定滑轮的两边,空心球
1 Foreword The swirling sedimentation tank in the plate mill is deeper than the ground and there is some difficulty in observing the water level on the ground. However, the water level has a great influence on the production. Too high is not conducive to the mill’s drainage. If it is too low, the pump works in an abnormal state, affecting Pump life. Based on this situation, we have designed a set of water level alarm device, which is used on site and plays a very good role in the operator’s timely operation. 2 working principle shown in Figure 1, the gravity of the hollow ball G and the gravity g of the counterweight hanging on both sides of the fixed pulley, hollow ball
