在供水企业卧式水泵机组的安装中,电机与水泵的联接,大都采用弹性柱销式联轴器,采用此种联轴器传递扭矩,安装时一般是借助于测量两个联轴器的相对位置,来保证电机轴的中心线与水泵轴的中心线,在同一直线上,若电机轴与水泵轴相对倾斜或不同心,轻者会使轴和轴承引起附加载荷,引起机组异常振动,加速零件磨损,重者将直接损坏电机、水泵零件,造成无法使用。因此安装时,对两个联轴器轮缘的径向误差、轴向间距误差都有严格的要求,以保证电机轴与水泵轴同心。 In the water supply enterprise horizontal water pump unit installation, motor and pump connection, most of the use of flexible pin type coupling, the use of such coupling torque transmission, installation is usually by means of measuring the relative two coupling Position, to ensure that the motor shaft centerline and the pump shaft centerline, in the same line, if the motor shaft and the pump shaft relative tilt or not the heart, the light shaft and bearings will cause additional load, causing the unit abnormal vibration, acceleration Parts wear, serious cases will directly damage the motor, pump parts, resulting in unusable. Therefore, the installation, the two radial flange coupling error, axial spacing error has strict requirements to ensure that the motor shaft and pump shaft concentric.
