离心泵安装顺序的介绍

离心泵安装顺序:
1、机组运至现场时,附带底座者已将水泵和电机校正,找平底座时可不必卸下水和电机,所以安装十分方便;
2、将底座放在基础上,并在地脚螺钉附近垫楔形铁,将底座垫高20~40毫米,作校平后填充水泥浆之用;
3、用水平仪检查底座的水平度,找平后用水泥浆填充底座,待水泥干涸后应再次检查水平度;
4、当机组功率较大时,为了方便运输可能会将、电机及底座分开包装,这时即需要用户自行安装,校正水泵机组,其方法如下:
A、将底座的支承平面、水泵脚和电机脚平面上的污物清除干净,并将水泵和电机放到底座上;
b、调整泵轴水平,找平后用螺栓将水泵固定在底座上,以防走动;
c、吊起电机,使泵联轴器和电机联轴器配合,放下电机到底座上相应位置;
d、调整两联轴器间隙为5mm左右,并校正电机轴与泵轴的轴心线是否重合,其方法是将平尺放在联轴器上,两联轴器外圆应与平尺相平,若不重合,应调整电机或的相对位置,或垫以薄铁片来调整;
e、为了检查安装精度,要在联轴器圆周上几个不同的位置用塞尺测量两联轴器平面间的间隙,联轴器平面一周上最大和最小的间隙之差不得超过0.3mm,两端中心线上下或左右的差数不得超过0.1mm。
5、当机组不带底座时,则需在基础上直接安装,其方法与4、相似,但应更加注意校正。
