從大型剛性密(mì)封
磁力泵(bèng)
的閥體密封圈(quān)和閥闆(pǎn)密封圈的結構特(tè)點來(lái)看，其密封(fēng)面上(shàng)堆焊(hàn)了硬質合(hé)金，硬度很(hěn)高，加(jiā)工時(shí)進刀(dāo)量很(hěn)難把(bǎ)握，實(shí)際生産中(zhōng)很(hěn)難一次(cì)加工成(chéng)形；密封(fēng)面帶有一定的(de)弧度，磁力(lì)泵加工過(guò)程中(zhōng)需要(yào)制作特殊樣闆(pǎn)，以随時(shí)在加工(gōng)中檢驗密(mì)封面(miàn)的弧形；密封面(miàn)的表(biǎo)面粗糙度要求很高，必須(xū)有相應的加工(gōng)工裝來保證。爲(wèi)此，我們結合生(shēng)産實際，采取了(le)以下兩(liǎng)方(fāng)面措(cuò)施來保證加工(gōng)要求：改進了
磁(cí)力泵(bèng)
加工工藝(yì)，進行了特(tè)殊加工；制(zhì)作特(tè)殊的(de)工裝(zhuāng)，保證(zhèng)密封(fēng)面的加工(圖\文(wén)

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.
