4、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。2.3.3 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GB/T292-94角接觸球軸承以外，其余泵型的整個轉(zhuǎn)子由兩端 的圓柱滾子軸承GB/T283-94支承；軸承采用 3號通用鋰基潤滑脂潤滑。由于MD6-25 MD12-25型泵軸承采用了GB/T292-94角接觸球軸承，所以轉(zhuǎn)子無軸向竄動量，其余泵型的轉(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，此軸向力由平衡裝置承擔(dān)。泵的平衡裝置

5、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)節(jié)平衡水管部件內(nèi)水的流動。09876543210987654321圖構(gòu)結(jié)泵心離級多磨耐用礦煤審1圖件部 蓋 盤管 壓 衡封料料 平水填填7 110段蓋水尾出(體段套環(huán)函出衡衡料吐平平填) )3 116件部管水套 段葉衡葉 中導(dǎo)平導(dǎo)9 0 1 2)段水進(jìn) 栓( 螺段環(huán) 緊入封輪 拉吸密葉3、技術(shù)特性一性能曲線及性能表件部承軸動滾3承軸動滾 3 件部器軸聯(lián)性彈銷柱35 6 7 8型號級數(shù)流量Q揚(yáng)程H(m)轉(zhuǎn)速n(r/min)效率n(%)功率(kw)必需汽 蝕余
