基于机械振动、瓦斯抽采泵气蚀及水击振动等造成地面瓦斯抽采泵等设备移动错位易造成联轴器中间的尼龙棒断裂的问题,分析其形成的主要影响因素;结合SEW减速机安装的精度要求,利用千分表轴向径向对中法对抽采泵、减速机、电机3种设备之间的连轴器进行同轴度检测;分别测量其轴心径向位移和两轴线的倾斜度,并利用相似三角形计算法来确定同轴度偏差的调整量及设备底座调平的方法;为瓦斯抽采泵定期进行同轴度检测提供简便易行的检测和调整办法。
Based on the mechanical vibration, gas drainage pump and water hammer vibration caused by the ground gas extraction pump and other equipment, mobile dislocation easily lead to the middle of the coupling nylon rod fracture problem, analysis of the formation of the main factors; combined with SEW reducer The accuracy of the installation requirements, the use of dial-axis radial alignment method on the extraction pump, reducer, motor coupling between the three kinds of equipment for coaxial detection; were measured radial displacement of the shaft and the two The inclination of the axis, and the use of similar triangulation to determine the amount of deviation adjustment coaxiality and leveling of the equipment base method; for gas extraction pump on the coaxiality detection to provide easy and convenient way to detect and adjust.
