（二）泵盖是泵与进水管相连的零件，其端面与叶轮之间留有规定的轴向端面间隙（在消除轴承轴向活动间隙以后，保持规定的轴向间隙）。间隙过小产生磨擦，过大则会导致泵内压力水回流，使泵的效率降低，通过增减调整纸垫达到规定的间隙。

ii.  pump cover is

the part connected with water inlet pipe.there is an stated axial end face gap

between its end

face and

impeller(keep the stated axail gap after removing the bearing axial movable
