從大型剛性密封磁力泵的閥體密封圈和閥板密封圈的結(jié)構(gòu)特點(diǎn)來看，其密封面上堆焊了硬質(zhì)合金，硬度很高，加工時(shí)進(jìn)刀量很難把握，實(shí)際生產(chǎn)中很難一次加工成形；密封面帶有一定的弧度，磁力泵加工過程中需要制作特殊樣板，以隨時(shí)在加工中檢驗(yàn)密封面的弧形；密封面的表面粗糙度要求很高，必須有相應(yīng)的加工工裝來保證。為此，我們結(jié)合生產(chǎn)實(shí)際，采取了以下兩方面措施來保證加工要求：改進(jìn)了磁力泵加工工藝，進(jìn)行了特殊加工；制作特殊的工裝，保證密封面的加工(圖\文www.www.kxxljsfx.com.cn/)。

From the large rigid sealed magnetic pump sealing ring of the valve body and the valve plate sealing ring structure characteristics, its sealing cover welding hard alloy, hardness is high, the amount of feed processing when it is difficult to grasp, in actual production, it is difficult to a forming; seal with a certain radian, magnetic pump processing need to make a special model, to be in the process of testing sealing surface arc; the sealing surface of the surface roughness of the high demand, must have corresponding processing tooling to ensure. To this end, we combine the actual production, take the following two measures to guarantee the processing requirements: improved magnetic pump processing technology, undertook special processing; production of special tooling, ensure the sealing surface processing.
