1.*設(shè)計(jì)研發(fā)，密封黃山市的工業(yè)泵無(wú)泄漏：泵采用機(jī)械密封加強(qiáng)制密封形式，密封腔壓力與吸入壓力相通，同時(shí)結(jié)構(gòu)設(shè)計(jì)上對(duì)密封充分冷卻循環(huán)，保證密封效果，無(wú)泄漏； 2.結(jié)構(gòu)布局*，符合國(guó)家標(biāo)準(zhǔn)，性能*：改變傳統(tǒng)高壓平衡技術(shù)，采用低壓平衡，主、從桿的軸向力低壓平衡裝置，受力平衡均勻，螺桿不變形，運(yùn)行可靠穩(wěn)定，無(wú)脈動(dòng)，噪音低； 3.外形美觀，符合人體視覺(jué)效果：改變傳統(tǒng)的進(jìn)、出口的位置，使得進(jìn)出口分布在泵兩側(cè)并成一條直線，外形美觀，同時(shí)在設(shè)計(jì)上進(jìn)行創(chuàng)新，在用戶(hù)現(xiàn)場(chǎng)不用改變管線就可實(shí)現(xiàn)進(jìn)出口的互換； 4.積木式組件，方便維修和配件更換：泵結(jié)構(gòu)簡(jiǎn)單緊湊，泵總成采用組件式結(jié)構(gòu)，可整體取出，便于維護(hù)、修理； 5.安全閥組件，保護(hù)泵安全使用：泵所配安全閥可以瞬間保護(hù)泵，防過(guò)載，但不能作為管道的溢流閥使用； 6.進(jìn)出口多種組合形式，方便現(xiàn)場(chǎng)管道連接； 7．多種安裝方式，更好滿足工況安裝要求三：HSNS三螺桿泵可輸送介質(zhì) 1、普通潤(rùn)滑性液體：液壓油，機(jī)械油，潤(rùn)滑油，齒輪油，礦物油，原油，淬火油，變壓器油，汽輪機(jī)油，水乙二醇，動(dòng)植物油等 2、低潤(rùn)滑性液體：燃油，輕柴油，重柴油，燃料油，重油，渣油，含臘稀油，冷卻液，皂化液等 3、粘性液體：各種合成橡膠液，人造膠液等四：HSNS三螺桿泵行業(yè)應(yīng)用 HSNS三螺桿泵應(yīng)用在建材行業(yè)中用做液壓、潤(rùn)滑裝置泵以及燃油噴油、窯頭點(diǎn)火泵。在化學(xué)石油化工和食品工業(yè)中用做裝載、輸送、增壓泵在船舶上用做輸送、增壓、燃油噴射、潤(rùn)滑以及船用液壓裝置泵在公路、鐵路建設(shè)中用做瀝青輸送泵在供熱設(shè)備中用做燃油噴油、燃油供應(yīng)和輸送泵在機(jī)械工業(yè)中用做液壓系統(tǒng)循環(huán)泵、潤(rùn)滑系統(tǒng)輸送泵及管道沖洗泵。五、HSNS三螺桿泵型號(hào)：
