DG(P)型自平衡多級鍋爐給水泵結(jié)構(gòu)形式:
該泵為臥式節(jié)段式多級離心泵,泵的吸入口可以垂直向上或水平、排出口垂直向上布置。主要有:進水段、中段、出水段、次級進水段、正導(dǎo)葉、反導(dǎo)葉、正葉輪、反葉輪、軸、節(jié)流、減壓裝置、擋套、軸承體、過渡管等零件組成;中段由高強度的穿杠螺栓和進出水段聯(lián)接,泵的進水段、中段、出水段之間的密封面均采用二硫化鉬潤滑脂金屬面硬密封;轉(zhuǎn)子由裝在軸上的正葉輪、節(jié)流減壓裝置、反葉輪、軸套、軸承擋套等零件組成;軸承采用“固-游式”干油潤滑結(jié)構(gòu),驅(qū)動端采用圓柱滾子軸承,末端采用角接觸球軸承;泵的工作室由進水段、中段、出水段、次級進水段、正導(dǎo)葉、反導(dǎo)葉、過渡管等組成;轉(zhuǎn)子部分與固定部分之間裝有密封環(huán)、導(dǎo)葉套等進行密封。DG(P)型自平衡多級鍋爐給水泵主要配置:
泵的材質(zhì)低配置是采用鑄鋼材質(zhì),可以根據(jù)用戶要求采用不銹鋼材質(zhì)。
DG(P)型自平衡多級鍋爐給水泵性:
該泵傳統(tǒng)多級離心泵的結(jié)構(gòu)形式進行了創(chuàng)新,取消了多級離心泵的軸向力平衡機構(gòu),、是采用平衡盤或平衡鼓結(jié)構(gòu)的D、DG型多級離心泵的替代品。由于無平衡裝置,即無平衡盤的園盤摩擦損失又無平衡回流損失,所以泵效率比同類別多級泵提高5-14%,同時解決因平衡裝置失效而導(dǎo)致平衡盤和平衡盤座的磨損或轉(zhuǎn)子咬死等各種故障,大大延長泵的使用壽命。
