3GBW保溫三螺杆(gǎn)泵是一種容積(jī)式泵,顯著的(de)優點是結構簡(jiǎn)單、體積小,允許高轉速工作(zuò)平穩可靠、壓力脈(mò)動小、流量(liàng)穩定、噪音低、效率高,正是利用螺杆齧合原理,依靠(kào)旋轉的螺杆在(zài)泵套內相互齧合,把被輸送的介質封閉(bì)在齧合髒內,沿(yán)螺杆軸向(xiàng)連續勻速地推至排出(chū)口,為(wéi)係統提供穩定的壓力。
保溫三螺杆泵(bèng)適(shì)用於輸送各(gè)種無腐蝕性油類及類似油的液體,輸送液體的粘度一般為3 0~760mm/s。高粘度介質可通過加溫降粘後輸送,其溫度一般不超(chāo)過(guò)350℃。30GB係列三螺杆泵采用鑄鋼製成,建議高粘度介質采用保溫結構的螺杆泵。泵的進出口方向,在通(tōng)常情(qíng)況下按圖示方向出廠即右進左(zuǒ)出,如用戶有特(tè)殊要(yào)求也可做成左進(jìn)右出(chū)。
該泵密封性能好,采用機械密封,根據用戶不同(tóng)的介質,機械密封磨擦件選用不同的材(cái)質,對於高粘度介質。選(xuǎn)用(yòng)機械(xiè)強度高、耐磨(mó)性好的(de)硬質合金材料,保障了(le)高溫下的密封(fēng)性(xìng)能。
3GBW保溫三螺杆(gǎn)泵(bèng)所輸液體為各種不含固體顆粒,無腐蝕性油類及類似油的潤滑性液體,要(yào)比齒輪泵運轉平穩,噪音低(dī),壽命長,但價格要高。所輸(shū)液體粘度為1.2~100OE(3.0~760cst),含高粘度液體亦可通(tōng)過加溫降粘後輸送.
3GBW保溫三螺杆泵泵是一種(zhǒng)內齧合偏心回轉(zhuǎn)的容(róng)積泵,泵的主要構件:一根單頭螺旋的轉子和一個(gè)通(tōng)常用彈性材料製造的具有雙關螺旋的定子,當轉(zhuǎn)子在定於型腔內(nèi)繞定子的軸線作行星回轉(zhuǎn)時,轉定子之間形成的密閉腕就沿轉(zhuǎn)子螺線產生(shēng)位移(yí);因此就將介質連續地(dì),均速地、而且容積恒定地從吸入口(kǒu)送到壓(yā)出端,基於這件(jiàn)特性(xìng),單螺杆泵特別適合於下列工況的工作(zuò)。
3GBW保溫三螺杆(gǎn)泵的主要過流部位均設有(yǒu)空心夾層,並(bìng)設有可供通蒸氣,熱/熱水,導熱油等對輸送液體和泵進行加熱,保溫等功能(néng),當輸送(sòng)粘度較大時應采用調(diào)速電機等傳動方式,降低泵(bèng)的轉速.
