20Sh-9B型水泵泵轴由两个单列向心球轴承支承，轴承装在泵体两端的轴承体内，用黄油润滑，双吸密封环用以减少水泵压水室的水漏回吸水室。

　　装配与拆卸

　　1 、装配转子部件:依次将叶轮、轴套、轴套螺母、填料套、填料环、填料压盖，挡水圈、轴承部件装在泵轴上，并套上双吸密封环，然后装上联轴器。

　　2、将转子部件装在泵体上，调整叶轮的轴向位暈到两侧双吸密封环的中间加以固定，将轴承体压盖同固定螺钉紧固。

　　3、装上填料，放好中开面纸垫，盖上泵盖打紧螺尾柱销后，拧紧泵盖螺母，最后装上墳料压盖。但不要将填料压得太紧，填料过紧会使轴套发热，耗费功率较大，也不要压得太松，过松会使液体渗漏大，水泵效率降低。                                          本厂合作单位有:桂平市金雅选矿厂（公司）;海城市光大高纯镁砂厂;滦平县周营铁矿;浮山县大华铁矿;砚山县阿舍冶炼厂;赤峰市元宝山区风水沟镇风海煤矿;郑州磴槽企业集团金岭煤业公司;烟台万得富实业公司;湘煤集团马田矿业公司芝兰冲煤矿;河北金牛能源股份公司东庞矿等。                                          20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵;20Sh-9B型水泵
