Run Chuan lubricating oil pump, hydraulic pump, oil pump / Tianjin screw pump 3GR85*2W2
一、特點:
One, the characteristic:
三螺桿泵包括3G 3GR三螺桿泵通用型,3GC 船用三螺桿泵型及3GS三螺桿泵 3GCL三螺桿泵 3GCLS三螺桿泵等特殊型。三螺桿泵是轉子式容積泵,由于主動螺桿與從動螺桿上螺旋槽相互嚙合及它們與襯套三孔內表面的配合,得以在泵的進出口之間形成數*動密封腔室,這些動密封腔室將不斷把液體由泵進口軸向移動到泵出口,并使所輸液體逐*升壓,從而形成一個連續、平穩、軸向移動的壓力液體。
Three screw pump including 3G 3GR three screw pump universal pump type and 3GS three screw, three screw pump 3GCL three screw pump3GCLS three screw pump and other special type of 3GC ship. Three screw pump's rotor type displacement pump, the driving screw and the driven screw spiral groove meshed with each other and they and the Bush inner surface with three holes, to form number level dynamic sealchamber between the import and export of the pump, the dynamic seal chamber will continue to put the liquid from the pump inlet to the pump outlet axial movement, and the the transfusion step, so as to form acontinuous, stable, the axial movement of the pressure of liquid.
二、適用介質及性能范圍:
Two, suitable for medium range and performance:
三螺桿泵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,所輸液體粘度為1.2~100°E(3.0~760cst),高粘度液體亦可通過加溫降粘后輸送。流量范圍0.2~590m3/h,*高工作壓力100bar,*高溫度150℃。
Three screw pumps transport liquid without solid particles, liquid lubricating oils and oil of similar non corrosive, lose liquid viscosity of 1.2~100 degree E (3.0~760cst), high viscosity liquids or viscosity by heating after the delivery. Flow range of 0.2~590m3/h, the maximum working pressure is 100bar, the maximum temperature of 150 degrees.
三、結構:
Three, structure:
3GR85*2
3GR85*2
1、結構簡單:具有多種結構形式,一般小流量0.2~6.5m3/h,泵的泵體和襯套合為一體(統稱泵體),軸封為機械密封。
1, the structure is simple: with a variety of structural form, usually a small flow of 0.2~6.5m3/h, pump body and the liner into one (collectively referred to as the pump), seal mechanical seal.
中等流量以上的泵襯套為一單獨的零件固定于泵體內,大流量泵多制成雙吸結構臥式安裝,軸封根據輸送介質的不同有機械密封和填料密封兩種。
Medium flow above for a single pump bushing fixed in the pump body parts, large flow pump more than double suction structure made ofhorizontal installation, seal according to the different transmission mediaare two kinds of mechanical seals and packing seal.
船用泵的安裝形式有臥式和立式兩種,原動機為交、直流船用電動機。
Marine pump installed in the form of a horizontal and vertical two kinds,the original motivation for the AC and DC motor ship.
2、壽命長:三螺桿泵的主動螺桿由電動機驅動,主、從桿之間沒有機械接觸,而由所輸壓力液體驅使從桿繞軸心線自轉,主、從桿之間、螺桿與襯套之間皆有一層油膜保護,因而泵的機械摩擦極小,壽命堪稱半*久性。
2, long service life: active screw and three screw pump driven by a motor,the Lord, have no mechanical contact from the pole, lost by the pressure of the liquid drives from the rod rotation around the axis line, the main,from between the rod and between the screw and bushing has a layer of oil film protection, so very small mechanical friction pump, life called semi permanent.
3、所輸液體在泵內作軸向勻速直線運動,故壓力脈動小,流量穩定,噪音低,由于轉動部件慣性小,則起動力矩和振動很小。
3, the transfusion liquid axial uniform linear motion in the pump, so the pressure fluctuation is small, the flow stability, low noise, due to the inertia of rotating parts is small, the starting torque and vibration is small.
4、具有高吸入能力。
4, with high suction capacity.
5、為*保*泵,電機及管路系統的安全,中等流量以上的螺桿泵均帶有安全閥當壓力超過安全閥的設定壓力時,高壓油將回流至泵的進油
5, to ensure the pump, motor and pipeline system safety, traffic over the middle screw pump is provided with a safety valve when the pressure exceeds set pressure of safety valve, high pressure oil into the oil will flow back to pump

1、 嚴禁無介質空轉,啟動開車前請務必加入潤滑性介質或輸送介質。
2、 嚴禁一切雜物焊渣等進入泵腔內,務必保持泵腔和管道內部的清潔度。
3、 嚴禁使用管道過濾器或Y型過濾器裝置,配置過濾器請*保*過濾面積是泵進口通徑截面積的20-30倍。并依據介質的清潔度正確配置過濾網的目數。
4、 嚴禁泵的進出口管道與泵的進出口管道不匹配,管道通徑配置必須和泵的進出口通徑一致。以免發生汽蝕或無法自吸。管道過細必定導致汽蝕,從而使泵處于吃不飽的狀態下工作,導致三螺桿泵組流量壓力下降甚至是異常的振動和噪音,長時間運行還將導致卡泵和螺桿泵的嚴重損壞,
5、 三螺桿泵的安裝高度必須充分考慮泵的汽蝕條件和泵的自吸能力(汽蝕余量與介質粘度轉速和螺桿的導程有關)
6、 由于包裝 運輸 起吊 裝卸以及管道螺栓緊固的作用可能易使泵的原出廠定位產生變化甚至嚴重錯位,所以三螺桿泵組管系配置安裝固定完畢后,一定要在啟動開車之前重新檢查三螺桿泵和電機的同軸度。
7、 嚴禁背壓啟動開機和關閉進口出口閥門的情況下啟動開機。
8、 嚴禁不符合泵旋轉標識的方向啟動旋轉。
9、 雙泵并聯必須在泵的出口和進口加單向閥,以防止介質倒流驅動三螺桿泵反轉。
10、嚴禁隨意調整安全閥螺栓。安全閥僅作為保護泵的安全和電機功率與泵工作狀態的匹配,嚴禁作為調壓閥和溢流閥使用。
