川潤潤滑油泵,液壓油泵,重油泵//天津螺桿泵3GR85*2W2
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(zhuǎn)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(nèi)表面的配合,得以在泵的進(jìn)出口之間形成數(shù)級動密封腔室,這些動密封腔室將不斷把液體由泵進(jìn)口軸向移動到泵出口,并使所輸液體逐級升壓,從而形成一個連續(xù)、平穩(wěn)、軸向移動的壓力液體。

二、適用介質(zhì)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,最高工作壓力100bar,最高溫度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(jié)構(gòu):
Three,?structure:
3GR85*2
3GR85*2
1、結(jié)構(gòu)簡單:具有多種結(jié)構(gòu)形式,一般小流量0.2~6.5m3/h,泵的泵體和襯套合為一體(統(tǒng)稱泵體),軸封為機(jī)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(dú)的零件固定于泵體內(nèi),大流量泵多制成雙吸結(jié)構(gòu)臥式安裝,軸封根據(jù)輸送介質(zhì)的不同有機(jī)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(jī)為交、直流船用電動機(jī)。
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(jī)驅(qū)動,主、從桿之間沒有機(jī)械接觸,而由所輸壓力液體驅(qū)使從桿繞軸心線自轉(zhuǎn),主、從桿之間、螺桿與襯套之間皆有一層油膜保護(hù),因而泵的機(jī)械摩擦極小,壽命堪稱半永久性。
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(nèi)作軸向勻速直線運(yùn)動,故壓力脈動小,流量穩(wěn)定,噪音低,由于轉(zhuǎn)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、為保證泵,電機(jī)及管路系統(tǒng)的安全,中等流量以上的螺桿泵均帶有安全閥當(dāng)壓力超過安全閥的設(shè)定壓力時,高壓油將回流至泵的進(jìn)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
