class="box"><p><p> 螺桿泵機械密封漏油現(xiàn)象及其控制方法：依靠密封在一個殼體中的兩個或兩個以上螺桿，在相互嚙合過程中所產(chǎn)生的工作空間容積變化來輸送液體的泵。三螺桿泵是依靠泵缸與嚙合螺桿間所形成的工作容積變化和移動來輸送液體或使之增壓的回轉(zhuǎn)泵。由三個螺桿、泵體與前后蓋組成兩個封閉空間，當(dāng)螺桿轉(zhuǎn)動時，螺桿脫開側(cè)的空間的體積從小變大，形成真空，將液體吸入，螺桿嚙合側(cè)的空間的體積從大變小，而將液體擠入管路中去。吸入腔與排出腔是靠兩個螺桿的嚙合線來隔開的，吉林G型單桿泵螺桿泵業(yè)效果好。三螺桿泵的排出口的壓力完全取決于泵出處阻力的大小。三螺桿泵油封竄油現(xiàn)象及其控制方法：1.零部件制造質(zhì)量的影響（1）油封質(zhì)量。如油封唇口幾何形狀不合格，縮緊彈簧太松等，造成氣密性試驗漏氣，三螺桿泵裝入主機后竄油。此時應(yīng)更換油封并檢驗材質(zhì)及幾何形狀（國產(chǎn)油封與國外先進(jìn)油封相比質(zhì)量差距較大）。（2）三螺桿泵的加工、裝配。如若三螺桿泵加工、裝配有問題，致使螺桿軸回轉(zhuǎn)中心與前蓋止口不同心，吉林G型單桿泵螺桿泵業(yè)效果好，會造成油封偏磨。此時應(yīng)檢查前蓋軸承孔對銷孔的對稱度、位移量，骨架油封對軸承孔的同軸度。（3）密封環(huán)材質(zhì)及加工質(zhì)量。若存在此問題，吉林G型單桿泵螺桿泵業(yè)效果好，致使密封環(huán)產(chǎn)生裂紋和劃傷，造成二次密封不嚴(yán)甚至失效。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吉林G型單桿泵螺桿泵業(yè)效果好"

從而保證了三螺桿泵具有很是好的使用壽命。二、主要特性、效率高對于γ=1500mm2/s、△P=、Q=115/h，泵的總效率可達(dá)85%以上。二、性能規(guī)?！鱌=，只要增加螺桿導(dǎo)程數(shù)，壓力可以更高、可輕易到達(dá)△P=。Q=115/h流量歸屬中等偏高。3、吸入性能較好對于以上性能要求，泵的必需汽蝕余量NPSH=，此時泵配套6級電機，螺桿為小導(dǎo)程。4、結(jié)構(gòu)簡略只有一套機械密封和一套軸承，泄漏點少、軸承只起定位作用，保證機械密封可靠地事情，承受載荷很是小，潤滑油利便、壽命長。5、使用維護(hù)利便，成本低由于結(jié)構(gòu)簡略，且泵的構(gòu)成*靠各零件自身的精度保證，不存在選配或者調(diào)整，拆檢利便快捷，維修簡略、修復(fù)更換元件后不傭人的勞力定位，泵的性能恢復(fù)可達(dá)**，可單獨更換泵內(nèi)任一元件，使維護(hù)成本降至較低。6、抗磨蝕性較好對于原油中的細(xì)砂或者面砂，不會影響泵的正常運轉(zhuǎn)，由于螺桿直徑小，轉(zhuǎn)速低，螺桿自身磨損很小很小，三螺桿泵的磨損主要存在于從桿和襯套孔之間，由于從桿要求承受一定的徑向力，在油膜破損的情況下，就要發(fā)生金屬接觸動到磨損，因此泵的結(jié)構(gòu)設(shè)計就很重要，壓力越高，泵的導(dǎo)程數(shù)就應(yīng)越多，這樣從桿和襯套孔之間單位面積的壓力就越小，磨損的可能也就越小。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="吉林G型單桿泵螺桿泵業(yè)效果好"

在內(nèi)置軸承的結(jié)構(gòu)型式中軸承由輸送物進(jìn)行潤滑油。外置軸承結(jié)構(gòu)的雙螺桿泵事情腔同軸承是分隔的。由于這種泵的結(jié)構(gòu)和螺桿間存在的側(cè)間隙，它可以輸送非潤滑油性介質(zhì)。此外，調(diào)整同步齒輪要得螺桿不接觸，同時將輸出扭矩的一半傳給從動螺桿。正如所有螺桿泵一樣，外置軸承式雙螺桿泵也有自吸能力，而且多數(shù)泵輸送元件本身都是雙吸對稱布置，可消弭軸向力，也有很大的吸高。泵的這些特性使它在油田化工和船只工業(yè)中得到了***的應(yīng)用。外置軸承式雙螺桿泵可根據(jù)各種使用情況分別采用平凡鑄鐵、不銹鋼等不同材料制造。輸送溫度可達(dá)250oD。泵具有不同方式的加熱結(jié)構(gòu)，定見流量可達(dá)2000立方米/鐘頭。二、主要特征：1、效率偏低由于雙螺桿泵是靠機械的方式人為地將主、從桿和襯套隔開，其間隙均很大一般在0mm以上，故高壓時容量效率偏低，同時由于其螺桿直徑大，相對三螺桿泵主桿直徑D=&P你好;160mm，雙螺桿泵直徑為D=&P你好;268mm以上，而且齒深較大、機械密封有四套，故其磨擦功率較大，導(dǎo)致泵的總效率偏低。對于不異性能指標(biāo)，其效率小于65%。二、性能規(guī)模雙螺桿泵中螺桿受徑向力，其值較大又由于螺桿軸為細(xì)長軸，兩端有軸承，中間受徑向力使其螺桿較易彎曲。</p><div
