上銳DG臥式多級(jí)泵產(chǎn)品概述:
上銳DG臥式多級(jí)泵可供輸送清水或物理化學(xué)性質(zhì)類似于清水的液體,適用于中、低壓鍋爐或次高壓鍋爐給水,也適用于工廠或城市高壓給排水。輸送介質(zhì)溫度為-20℃~150℃,進(jìn)口允許壓力小于0.6MPa。
DG該系列泵采用了國(guó)家推薦使用的高效節(jié)能產(chǎn)品的水力模型。具有效率高、性能范圍廣、運(yùn)轉(zhuǎn)安全和平穩(wěn)、噪音低、壽命長(zhǎng)、安裝維修方便等優(yōu)點(diǎn)。
DG臥式多級(jí)泵結(jié)構(gòu)特點(diǎn):
DG型臥式多級(jí)泵進(jìn)、出水口均為垂直向上,通過拉緊螺栓將泵的進(jìn)水段、中段、出水段、軸承體等泵殼體部分聯(lián)結(jié)成一體。根據(jù)泵的揚(yáng)程選擇泵的級(jí)數(shù)。
該系列泵轉(zhuǎn)子部分主要由及安裝在軸上的葉輪、軸套、平衡盤等零件組成,其中葉輪的數(shù)量根據(jù)泵的級(jí)數(shù)而定。軸上零件用平鍵和軸螺母緊固使之與軸聯(lián)為一體。整個(gè)轉(zhuǎn)子由兩端滾動(dòng)軸承或滑動(dòng)軸承支承。軸承按型號(hào)不同而定,均不承受軸向力,其軸向力由平衡盤平衡。泵在運(yùn)行中允許轉(zhuǎn)子在泵殼中軸向游動(dòng),不能采用向心軸承。滾動(dòng)軸承用油脂潤(rùn)滑、滑動(dòng)軸承用稀油潤(rùn)滑,并用油環(huán)進(jìn)行自潤(rùn)滑,循環(huán)水冷卻。
泵的進(jìn)水段、中段、出水段之間的密封面均采用二硫化鉬潤(rùn)滑脂密封,轉(zhuǎn)子部分與固定部分之間裝有密封環(huán)、導(dǎo)葉套等進(jìn)行密封,當(dāng)密封環(huán)和導(dǎo)葉套的磨損程度已影響泵的工作性能時(shí)應(yīng)予更換。
軸的密封形式有機(jī)械密封和填料密封兩種。泵采用填料密封時(shí),填料環(huán)的位置安放要正確,填料的松緊程度必須適當(dāng),以液體能一滴一滴滲出為宜。泵各種密封元件裝在密封箱內(nèi),箱內(nèi)要通過一定壓力的水,起水封、水冷或水潤(rùn)滑的作用。在軸封處裝有可更換的軸套,保護(hù)泵軸。次高壓泵一般采用滑動(dòng)軸承、稀油潤(rùn)滑結(jié)構(gòu),DG85-67、DG155-67型泵可采用滑動(dòng)軸承、稀油潤(rùn)滑,也可采用滾動(dòng)軸承、干油潤(rùn)滑結(jié)構(gòu),其余型號(hào)均采用滾動(dòng)軸承,干油潤(rùn)滑結(jié)構(gòu)。中、低壓泵的主要零件材料一般采用優(yōu)質(zhì)鑄鐵,次高壓泵主要零件采用鑄鋼或不銹鋼。該系列泵通過彈性聯(lián)軸器由原動(dòng)機(jī)直接驅(qū)動(dòng),從原動(dòng)機(jī)方向看,泵為順時(shí)針方向旋轉(zhuǎn)。
