適于熱電廠,玻璃水泥建材廠,船舶,化工,制藥廠,公路瀝青攪拌站、鋼鐵廠高爐，高壓蒸汽鍋爐，燃油鍋爐，船用鍋爐，船舶工業(yè)，柴油發(fā)動機，渦輪鍋爐等燃油輸送系統(tǒng)或燃燒器燃油輸送噴燃應用；主要輸送燃料油、柴油、重油、潤滑油、液壓油、船用柴油，汽油（MDO,MGO),重型燃油HFO，車用燃油，生物油等或其它潤滑性液體，所輸介質(zhì)中不得含有任何磨料顆粒和對泵材料有腐蝕的物質(zhì)。 SPF系列三螺桿泵作為燃油的輸送泵和調(diào)節(jié)泵，廣泛用于油料運輸及加注，以及工業(yè)方面的管道輸送，并更多用于各種瀝青攪拌站和瀝青拌和站的燃燒器中和中小型齒輪箱齒輪減速機液壓潤滑設備。 可以提供電機+螺桿泵組裝成套供貨，附帶吸油管道和支架等，以及完整的測試報告；可以提供壓力安全閥組等配套附件；二、主要應用范圍 ? SPF 系列三螺桿泵在燃燒器燃油系統(tǒng)中用作輸送、噴燃、增壓及燃油爐的燃油泵； ? 在輸油系統(tǒng)中用作傳輸及加油泵增壓泵、噴燃泵、柴油點火油泵； ? 在一切工業(yè)領域中皆可用作潤滑油泵； ? 用于各種液壓傳動裝置中的液壓泵；三、結(jié)構(gòu) SPF 泵為內(nèi)置軸承自吸三螺桿泵，經(jīng)表面氮化硬化處理的螺桿，螺桿泵體表面特殊處理，硬度為63HRC；裝在一可更換的襯套內(nèi)運轉(zhuǎn)。主桿采用液壓平衡，從桿的軸向力支撐在后蓋上，并由液壓力驅(qū)動旋轉(zhuǎn)，因而螺桿型面僅傳遞液壓扭矩，并不受力，也無磨損，對全部傳動零件而言，均由被輸送介質(zhì)潤滑。主桿的徑向由平衡活塞定位，且借助于平衡活塞和軸套的間隙使高壓腔和密封腔分開，在密封腔內(nèi)裝有機械密封，腔內(nèi)的油液回油孔與泵的吸入腔相通，因而不受排出壓力的影響。所有滑動部件由介質(zhì)潤滑。軸封是采用機械密封，無泄漏且無須維修。密封室和吸進室由一個內(nèi)部回路連接。軸封上的輸出壓力是獨立，只有產(chǎn)生吸收壓力。泵和電機由支架連接。當螺旋轉(zhuǎn)動時，密封室的三個螺旋作軸向的*連續(xù)的運動。螺旋轉(zhuǎn)動不會引起震動。在擠壓之外，密封室容量不變。結(jié)構(gòu)設計和運轉(zhuǎn)的穩(wěn)定性，保證了螺桿泵操作很低的噪音和無脈動。泵由支架、聯(lián)軸器與電機聯(lián)接和驅(qū)動，（如規(guī)格20 型），亦可壁式安裝（如規(guī)格40 型）。四、特點可選擇徑向或軸向吸油口，SAE法蘭BSPP或螺紋連接；螺桿泵外部護套（可選）材質(zhì)為AMSE標準，可根據(jù)API標準制造；螺桿硬度為63HRC，超精密加工；介質(zhì)的zui低允許黏度為2cst，zui高1000cst,允許zui大顆粒物30um. 螺桿泵zui高壓力達4MPa; 流量范圍:0-120L/min 1． 運轉(zhuǎn)由特殊型線構(gòu)成的螺旋面的主動螺桿轉(zhuǎn)動時，其動密封腔室將把液體由吸入口吸入并沿軸向連續(xù)、無脈動的輸送到排出口。 2． 噪音、脈動螺桿泵的結(jié)構(gòu)和運轉(zhuǎn)的穩(wěn)定性，保證了泵的低噪音和無脈動。 3、軸封泵采用機械密封，該機械密封無需維修。結(jié)構(gòu)材料動環(huán) 浸漬樹脂石墨靜環(huán) 高碳鉻鋼 “O”型圈 氟橡膠彈簧 不銹鋼金屬元件 不銹鋼 4、溫度和壓力范圍允許溫度 150 ℃ （僅供應20 型一個規(guī)格）允許工作壓力 4.0 MPa 有關更高的使用溫度請與廠協(xié)商不同粘度、轉(zhuǎn)速下的工作壓力，按性能參數(shù)表格。 5． 安全閥每臺泵均裝有安全閥作為超載保護裝置。 6． 進出口法蘭進口法蘭：PN16DIN2533(GB2555-81) 出口法蘭：PN40DIN2535(GB2555-81) 7． 安裝 SPF 泵在任何地方皆可安裝使用，為了安全起見，電機不允許擺放在泵的下面。 8． 動力配套各種型式的電動機或其它驅(qū)動裝置通過聯(lián)軸器與泵進行聯(lián)接。三相交流電機，其防護等級為IP44，絕緣等級為B，功率及主要聯(lián)接尺寸均按Y 系列電機。 9. 電機規(guī)定頻率為50HZ，若無其它變化可用在60HZ 電源下工作。五、型式代號 SPF 20 R 38 G 10 F W2 1 2 3 4 5 6 7 8 ① 系列 ② 規(guī)格為轉(zhuǎn)速1450 rpm，螺旋角為46°時泵的理論流量 ③ 主桿螺旋旋 （R=右旋，L=左旋） ④ 螺旋角 ⑤ 軸承型式：內(nèi)置滑動軸承 ⑥ 機械密封 ⑦ 帶有過濾器（僅供應SPF20系列一個規(guī)格） ⑧ 材料組合六、SPF系列三螺桿泵常用規(guī)格型號： SPF10R28G8.3FW20三螺桿泵 SPF10R38G8.3FW20三螺桿泵 SPF10R46G8.2FW20三螺桿泵 SPF10R56G8.3FW21三螺桿泵 SPF10R38G8.3FW21三螺桿泵 SPF10R38G8.3FW21三螺桿泵 SPF20R38G10W20三螺桿泵 SPF20R46G10W20三螺桿泵 SPF20R56G10W20三螺桿泵 SPF20R38G10FW20三螺桿泵 SPF20R46G10FW20三螺桿泵 SPF20R56G10FW20三螺桿泵 SPF20R38G10W21三螺桿泵 SPF20R46G10W21三螺桿泵 SPF20R56G10W21三螺桿泵 SPF20R38G10FW21三螺桿泵 SPF20R46G10FW21三螺桿泵 SPF20R56G10FW21三螺桿泵 SPF20R38G10W23三螺桿泵 SPF20R46G10W23三螺桿泵 SPF20R56G10W23三螺桿泵 SPF20R38G10FW23三螺桿泵 SPF20R46G10FW23三螺桿泵 SPF20R56G10FW23三螺桿泵 SPF40R38G10W20三螺桿泵 SPF40R46G10W20三螺桿泵 SPF40R54G10W20三螺桿泵 SPF40R38G10FW20三螺桿泵 SPF40R46G10FW20三螺桿泵 SPF40R54G10FW20三螺桿泵 SPF40R38G10W21三螺桿泵 SPF40R46G10W21三螺桿泵 SPF40R54G10W21三螺桿泵 SPF40R38G10FW21三螺桿泵 SPF40R46G10FW21三螺桿泵 SPF40R54G10FW21三螺桿泵 SPF40R38G10W23三螺桿泵 SPF40R46G10W23三螺桿泵 SPF40R54G10W23三螺桿泵 SPF40R38G10FW23三螺桿泵 SPF40R46G10FW23三螺桿泵 SPF40R54G10FW23三螺桿泵
