DG鍋爐給水泵使用說明書解讀

1、DG型臥式多級鍋爐給水泵產(chǎn)品用途：本泵標準采用JB/T6435.2-92, GB5659-85多級離心泵技術條件。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

2、送介質(zhì)溫度為： -20 C150 C。允許進口壓力為 0.6MPa。參數(shù)范圍：3流量： 4 750m /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、水力設計：采用先進的設計理論進行低比轉(zhuǎn)數(shù)水力模型優(yōu)化設計,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

3、上零件用平鍵和 軸套螺母緊固使之與軸成為一體。整個轉(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)、導葉套、填料等密封,當密封環(huán)和導葉套的磨損程度己影響泵的工作和性能時 應予及時更換。泵采用中心支撐,填料函部位設有水冷腔。軸承體內(nèi)設水冷室,外表帶散熱片,具有很 好

4、的冷卻保護,中段殼體外設有一層保護罩,以防在抽送高溫介質(zhì)時液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。 從傳動端看,泵為順時針方向旋轉(zhuǎn)。型號說明：例 1: DG25-50X 5DG-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-20 C+80 C-20 C+150 C-20 C+150 C吸入段HT200ZG230-450ZG1Cr13中段HT200ZG230-450ZG1Cr13吐出段HT200ZG230-450ZG1Cr13葉輪HT200或
