在杂质泵生产过程中,过流部件是主要磨损零件,也是决定杂质泵使用寿命长短的主要因素之一。过流部件使用寿命愈长,则该泵的寿命愈长,过流部件的更换次数则愈少,维修强度也大大降低。要想获得使用寿命较长的过流部件,除了过流部件本身的材质因素起决定性作用外,制造工艺也是一个不可忽视的重要因素。因此,在相同材质的情况下, In the impurity pump production process, the over-current components are the main wear parts, but also determine the impurity pump life one of the major factors. The longer the life of the overcurrent component, the longer the life of the pump, the less the number of overcurrent components are replaced, and the maintenance strength is greatly reduced. To obtain over-current components with long service life, in addition to the material components of the overcurrent components play a decisive role, the manufacturing process is also an important factor can not be ignored. Therefore, in the case of the same material,
