2、其他污水的液體。特別適用于煤礦等礦山排水。MD型煤礦用耐磨多級離心泵保送的介質(zhì)溫度不高于80。1.2泵型號意義闡明MD450-606 100MD458MD煤礦用耐磨多級離心泵 100吸入口直徑為100mm450設(shè)計點流量m3/h MD煤礦用耐磨多級離心泵60設(shè)計點單級揚程m 45設(shè)計點單級揚程m6泵的級數(shù) 8泵的級數(shù)1.3性能范圍按設(shè)計點流量：6.3720 m3/h揚程：22.81140m1.4產(chǎn)品執(zhí)行規(guī)范：MT/T114-2005。 警告 警告a本系列泵的配套電機(jī)：YB(高壓)及YB2系列隔爆電動機(jī)可用于井下，但不能用于采掘任務(wù)面，用于采掘任務(wù)面必需配用YBK系列電動機(jī)，電動機(jī)必需求可靠接地

3、！b泵不允許在無液體介質(zhì)形狀下點動或運轉(zhuǎn)！c泵組的轉(zhuǎn)動部分在運轉(zhuǎn)時不準(zhǔn)觸摸！2、構(gòu)造特征MD型煤礦用耐磨多級離心泵為兩端支承，殼體部分為節(jié)段式，泵的傳動方式是經(jīng)過柱銷彈性聯(lián)軸器與電機(jī)結(jié)合，泵的旋轉(zhuǎn)方向，從驅(qū)動端看，泵為順時針方向旋轉(zhuǎn)。泵的構(gòu)造見圖1。2.1定子部分主要由吸入段進(jìn)水段、中段、吐出段出水段、導(dǎo)葉、填料函體尾蓋和軸承體等分別用拉緊螺栓聯(lián)接成一體，從聯(lián)軸器端看，泵吸入口為程度右方向，吐出口為垂直向上。2.2轉(zhuǎn)子部分主要由軸、葉輪、平衡盤、軸承及軸套等組成。2.3泵的密封2.3.1泵吸入段進(jìn)水段、中段、吐出段出水段之間的靜止結(jié)合面用紙墊或二硫化鉬來密封。2.3.2泵各級間采用節(jié)流密封。2

4、.3.3泵的兩側(cè)軸封采用軟填料密封。2.3.4采用擋水圈擋水，防止水進(jìn)入軸承。2.4軸承部分除MD6-25、MD12-25型泵軸承采用角接觸球軸承以外，其他泵型的整個轉(zhuǎn)子由兩端的圓柱滾子軸承支承；軸承采用3號通用鋰基光滑脂光滑。由于MD6-25、MD12-25型泵軸承采用了角接觸球軸承，所以轉(zhuǎn)子無軸向竄動量，其他泵型的轉(zhuǎn)子應(yīng)有軸向竄動量。2.5平衡部分由于葉輪前后蓋板受壓面積不等，產(chǎn)生軸向力，此軸向力由平衡安裝承當(dāng)。泵的平衡安裝由平衡盤、平衡套、平衡環(huán)組成。泵的平衡室由吐出段出水段、填料函體尾蓋、平衡水管部件所組成，平衡水管部件絕對不允許堵塞，可用閘閥調(diào)理平衡水管部件內(nèi)水的流動。3、技術(shù)特性性
