●特點：
3G三(sān)螺杆泵包括3G 通(tong)用型，3GC船用型及(ji)特殊型。3G三螺杆(gǎn)泵是轉子式容(rong)積泵，由于主動(dong)螺杆與從動螺(luó)杆上螺旋槽相(xiang)互齧合及它們(men)與襯套三孔内(nèi)表面的配合，得(dé)以在泵的進出(chū)口之間 形成數(shu)級動密封腔室(shì),這些動密封腔(qiang)室将不斷把液(ye)體由泵進口軸(zhou)向移動到泵出(chu)口，并使所輸 液(ye)體逐級升壓，從(cóng)而形成一個連(lián)續、平穩、軸向移(yí)動的壓力液體(ti)。Three-screw pump including 3 g, 3 g for general 3 gc Marine type and special type.3 g three screw pump is a positive displacement pump rotor type, due to the driving screw and driven screw spiral groove on the pitch and they cooperate with three hole on the surface of the liner, in between the import and export of the pump Form number level dynamic seal chamber, the dynamic seal chamber will continue to move from pump axial liquid pump discharge, and lose a liquid booster step by step, thus forming a continuous, smooth, axial movement of liquid pressure.
●3G三螺杆泵适用(yong)介質及性能範(fan)圍：3 g three-screw pump applicable medium range and performance
3G三螺杆泵所(suǒ)輸液體為各種(zhong)不含固體顆粒(li)，無腐蝕性油類(lèi)及類似油的潤(run)滑性液體，所輸(shu)液體粘度為1.2~100°E（3.0~760cst），高(gao)粘度液體亦可(ke)通過加溫降粘(zhan)後輸送。 流量範(fan)圍0.2~590m3/h，最高工作壓(ya)力100bar，最高溫度150℃。3 g three-screw pump of liquid for various not containing solid particles, non-corrosive oil lubricity and similar oil liquid, the liquid viscosity is 1.2 ~ 100 ° E (3.0 ~ 760 CST), high viscosity liquid can be transmitted through heating after the viscosity.Flow range of 0.2 ~ 590 m3 / h, maximum working pressure of 100 bar, the highest temperature of 150 ℃.
●3G三(sān)螺杆泵結構:
1、結(jié)構簡單：具有多(duo)種結構形式，一(yi)般小流量0.2~6.5m3/h，泵的(de)泵體和襯套合(he)為一體（統稱泵(beng)體），軸封為機械(xie)密封。Simple structure: has a variety of structural form, generally small flow of 0.2 ~ 6.5 m3 / h, pump body and pump bushing (generally referred to as the pump body), is an organic whole to shaft seal for the mechanical seal.
中等流量(liang)以上的泵襯套(tào)為一單獨的零(ling)件固定于泵體(tǐ)内，大流量泵多(duō)制成雙吸結構(gòu)卧式安裝，軸封(feng)根據輸送介質(zhi)的不同有機械(xie)密封和填料密(mì)封兩種。Medium flow above the pump sleeve is fixed in a separate pump body, big flow made double suction pump more structure horizontal installation, depending on the medium of the shaft sealing has two kinds of mechanical seals and packing seal.
3G船用泵(bèng)的安裝形式有(you)卧式和立式兩(liǎng)種，原動機為交(jiao)、直流船用電動(dòng)機。3 g Marine pump installations have horizontal and vertical two kinds, prime mover for Marine ac or dc motor.
2、壽命長：3G三螺(luo)杆泵的主動螺(luo)杆由電動機驅(qū)動，主、從杆之間(jiān)沒有機械接觸(chù)，而由所輸壓力(li)液體驅使從杆(gan)繞軸心線自轉(zhuǎn)，主、從杆之間、螺(luo)杆與襯套之間(jian)皆有一層油膜(mó)保護，因而泵的(de)機械摩擦極小(xiǎo)，壽命堪稱半永(yǒng)久性。Long life: 3 g three-screw pump active screw driven by a motor, no mechanical contact between master and slave rod, and by a liquid pressure driven from rod rotated on its axis, the Lord, from between rod, screw and bushing is a layer of oil film protection, thus pump mechanical friction small, life is a permanent.
3、所輸液體(ti)在3G三螺杆泵内(nèi)作軸向勻速直(zhí)線運動，故壓力(lì)脈動小，流量穩(wen)定，噪音低，由于(yú)轉動部件慣性(xing)小，則起動力矩(jǔ)和振動很小。
4、3G三(san)螺杆泵具有高(gāo)吸入能力。Of liquid in a 3 g three-screw pump axial uniform motion in a straight line, so the pressure fluctuation is small, flow stability, low noise, due to the small inertia rotating parts, starting torque and small vibration.
5、為保(bǎo)證3G三螺杆泵、電(dian)機及管路系統(tong)的安全，中等流(liú)量以上的螺杆(gan)泵均帶有安全(quán)閥，當壓力超過(guo)安全閥的設定(ding)壓力時，高壓油(you)将回流至泵的(de)進油口。In order to ensure the 3 g three screw pump, motor and the safety of the pipeline system, secondary flow above the screw pump is with safety valve, when pressure exceeds the set pressure of the relief valve, high pressure oil will flow back to the inlet of the pump.
