●特點：
3G三螺杆泵(beng)包括3G 通用型，3GC船用(yong)型及特殊型。3G三螺(luó)杆泵是轉子式容(rong)積泵，由于主動螺(luo)杆與從動螺杆上(shang)螺旋槽相互齧合(hé)及它們與襯套三(san)孔内表面的配合(he)，得以在泵的進出(chu)口之間 形成數級(ji)動密封腔室,這些(xie)動密封腔室将不(bu)斷把液體由泵進(jin)口軸向移動到泵(bèng)出口，并使所輸 液(yè)體逐級升壓，從而(ér)形成一個連續、平(píng)穩、軸向移動的壓(ya)力液體。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(bèng)适用介質及性能(néng)範圍：3 g three-screw pump applicable medium range and performance
3G三螺杆泵所(suo)輸液體為各種不(bu)含固體顆粒，無腐(fu)蝕性油類及類似(si)油的潤滑性液體(ti)，所輸液體粘度為(wei)1.2~100°E（3.0~760cst），高粘度液體亦可(kě)通過加溫降粘後(hou)輸送。 流量範圍0.2~590m3/h，最(zuì)高工作壓力100bar，最高(gao)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三螺杆泵結(jié)構:
1、結構簡單：具有(yǒu)多種結構形式，一(yī)般小流量0.2~6.5m3/h，泵的泵(bèng)體和襯套合為一(yi)體（統稱泵體），軸封(fēng)為機械密封。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(děng)流量以上的泵襯(chèn)套為一單獨的零(ling)件固定于泵體内(nèi)，大流量泵多制成(chéng)雙吸結構卧式安(an)裝，軸封根據輸送(song)介質的不同有機(ji)械密封和填料密(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船用泵的(de)安裝形式有卧式(shi)和立式兩種，原動(dòng)機為交、直流船用(yong)電動機。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(san)螺杆泵的主動螺(luo)杆由電動機驅動(dong)，主、從杆之間沒有(yǒu)機械接觸，而由所(suǒ)輸壓力液體驅使(shǐ)從杆繞軸心線自(zi)轉，主、從杆之間、螺(luo)杆與襯套之間皆(jie)有一層油膜保護(hu)，因而泵的機械摩(mo)擦極小，壽命堪稱(chēng)半永久性。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(yè)體在3G三螺杆泵内(nei)作軸向勻速直線(xiàn)運動，故壓力脈動(dòng)小，流量穩定，噪音(yin)低，由于轉動部件(jian)慣性小，則起動力(lì)矩和振動很小。
4、3G三(san)螺杆泵具有高吸(xī)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、為保證3G三(san)螺杆泵、電機及管(guǎn)路系統的安全，中(zhong)等流量以上的螺(luó)杆泵均帶有安全(quán)閥，當壓力超過安(an)全閥的設定壓力(lì)時，高壓油将回流(liu)至泵的進油口。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.
