In the process, with the outer diameter and inner diameter dial gauge micrometer accurate measurement of the plunger several times in size and ellipticity, as well as cylinder boreSlurry pumps diameter, taper, so that the piston and cylinder are matching with the clearance hole achieve 0.02_0.4mm requirements.
在此过程中，用外径千分尺和内径千分表多次准确测量柱塞的外径尺寸和椭圆度，和缸体孔孔径、锥度，使所选配的柱塞和缸体孔的配合间隙达到0.02_0.4mm的要求。
