11、的介質(zhì)溫度不高于420。1.2泵型號意義說明MD(P)280-65×6 100 MD (P)45×8MD (P)臥式多級離心泵 100吸入口直徑為100mm280設(shè)計點流量（m3/h） MD (P)臥式多級離心泵65設(shè)計點單級揚程（m） 45設(shè)計點單級揚程（m）6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：501140m1.4產(chǎn)品執(zhí)行標(biāo)準(zhǔn)：MT/T114-2005煤礦用多級離心泵，Q/CSB1-2007多級清水離心泵。警告a）本系列泵的配套電機：YB系列電機可用于井下，但不能用于采掘工作面，用于采掘工作面必須配用YBK系列電機，Y系列電機

12、不能用于井下，電機必須要可靠接地！b）泵不允許在無液體介質(zhì)狀態(tài)下點動或運轉(zhuǎn)！c）泵組的轉(zhuǎn)動部分在運行時不準(zhǔn)觸摸！1.5警告2、結(jié)構(gòu)特征自平衡多級泵為兩端支承，殼體部分為節(jié)段式，泵的傳動方式是通過柱銷彈性聯(lián)軸器與電機聯(lián)結(jié)，泵的旋轉(zhuǎn)方向，從驅(qū)動端看，泵為順時針方向旋轉(zhuǎn)。泵的結(jié)構(gòu)見圖1。2.1定子部分主要由吸入段（進水段）、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，泵吸入口為水平右方向，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（進水段）、中段、吐出段（出水段）之間的靜止結(jié)合面用紙墊

13、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，防止水進入軸承。2.4軸承部分除MD(P)6-25、MD(P)12-25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MD(P)6-25、MD(P)12-25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)。泵的平衡裝置由平衡盤、平衡套、平衡環(huán)組成。泵

14、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。3、技術(shù)特性性能曲線及性能表性能表型 號級數(shù)流量Q揚程H(m)轉(zhuǎn)速n(r/min)效率(%)功率(kw)必需汽蝕余量(NPSH)r(m)葉輪直徑(mm)質(zhì)量(kg)(m3/h)(L/s)軸功率Pa電機功率MD(P)6-2533.756.37.51.041.752.0876.57573.5295027.842.038.82.813.063.875.52.02.02.0138864102100983.754.085.167.5965127.5125122.54.685.
