以往型齿轮泵的泵体研损时,只能更换,不可修复。但是,该型号泵国内极少生产,加上体积又大,自制周期更长。我们在实践中,用更换齿轮的方法(见图示)使泵体得到了修复。要想修去泵体的研痕,必将扩大内孔尺寸。这样,内孔与齿顶圆的间隙就要变大,泵就不能工作。修复齿轮泵的方法:若是标准齿轮,就用变位齿 Prior gear pump research damaged, can only be replaced, can not be repaired. However, the model pump rarely produced in the country, coupled with the volume and large, self-made cycle longer. We practice in practice, the replacement of the gear method (see picture) to make the pump body has been repaired. To repair the pump marks, it is bound to expand the bore size. In this way, the gap between the inner hole and the tip circle should become larger, and the pump can not work. Repair gear pump method: If the standard gear, the use of variable teeth
