DG鍋爐給水泵使用說明書

1、DG型臥式多級鍋爐給水泵產(chǎn)品用途：本泵標(biāo)準(zhǔn)采用JB/T6435.2-92，GB5659-85多級離心泵技術(shù)條件。DG型臥式多級鍋爐給水泵是我廠根據(jù)工業(yè)鍋爐給排水有關(guān)規(guī)范開發(fā)的新產(chǎn)品。由于采用了國家推薦使用的高效節(jié)能產(chǎn)品的水力模型，因此DG型泵效率高、性能范圍廣、更好地滿足使用要求。用于替代老型號GC型離心泵，在結(jié)構(gòu)上采用了臥式、多級泵分段形式，因而運轉(zhuǎn)安全、平穩(wěn)、噪音低、壽命長、安裝維修方便。此型泵特別適用于工業(yè)鍋爐供排水、冷卻水輸送等。也可以通過改變材質(zhì)、密封形式和增加冷卻系統(tǒng)用于輸送熱水、油品、腐蝕介質(zhì)等，廣泛適用于石油化工、熱水循環(huán)、環(huán)保產(chǎn)業(yè)、純凈水輸送等行業(yè)。輸送介質(zhì)溫度為：-20C1

2、50C。允許進口壓力為0.6MPa。參數(shù)范圍：流量：4750m3/h揚程：841536m（揚程由泵的級數(shù)決定并通過切割葉輪直徑進行調(diào)節(jié)）產(chǎn)品特點：1、水力設(shè)計：采用先進的設(shè)計理論進行低比轉(zhuǎn)數(shù)水力模型優(yōu)化設(shè)計，葉輪流道采用特殊的工藝手段，使其流道表面光潔，減少損失，提高效率。2、結(jié)構(gòu)：在結(jié)構(gòu)上采用臥式、多級分段形式，因而運轉(zhuǎn)安全、平穩(wěn)、噪音低、壽命長、安裝維修方便。3、泵效率高，性能范圍廠，更好地滿足使用要求。結(jié)構(gòu)：泵殼體部分主要由軸承體、吸入段、中段、吐出段、導(dǎo)葉等用拉桿螺栓聯(lián)接成整體。轉(zhuǎn)子部分主要由軸及安裝在軸上的葉輪、軸套、平衡盤等零件組成。軸上零件用平鍵和軸套螺母緊固使之與軸成為一體。整

3、個轉(zhuǎn)子由兩端軸承支承在泵殼體上，轉(zhuǎn)子部分中葉輪個數(shù)是根據(jù)泵的級數(shù)而定。本型泵軸承部分采用滾動軸承，部分采用滑動軸承，均不承受軸向力，泵軸向力由平衡盤承受，泵在運行中允許轉(zhuǎn)子部分在泵殼體中軸向游動。軸承采用32號軸承油（汽輪機油）或性能類似的其它油品潤滑，以獲得更好的潤滑性能及承受更高的溫度。泵的吸入段、中段、吐出段之間密封均采用二硫化鉬潤滑密封，轉(zhuǎn)子部分與固定部分之間靠密封環(huán)、導(dǎo)葉套、填料等密封，當(dāng)密封環(huán)和導(dǎo)葉套的磨損程度己影響泵的工作和性能時應(yīng)予及時更換。泵采用中心支撐，填料函部位設(shè)有水冷腔。軸承體內(nèi)設(shè)水冷室，外表帶散熱片，具有很好的冷卻保護，中段殼體外設(shè)有一層保護罩，以防在抽送高溫介質(zhì)時液

4、體從殼體接合面之間濺出。本型泵采用軟填料密封，也可以采用機械密封。填料及機械密封的松緊程度必須適當(dāng)。從傳動端看，泵為順時針方向旋轉(zhuǎn)。型號說明：例1：DG25-505DG臥式多級鍋爐給水泵 25泵的流量（m3/h）50泵的單級揚程（米）5泵的級數(shù)（葉輪個數(shù)）D G型 泵 材 質(zhì) 選 擇 表材 料 類 別IIIIII使 用 溫 度-20C+80C-20C+150C-20C+150C吸入段HT200ZG230-450ZG1Cr13中 段HT200ZG230-450ZG1Cr13吐出段HT200ZG230-450ZG1Cr13葉 輪HT200或CuZG230-450或CuZG1Cr13或Cu導(dǎo) 葉HT
