●特(tè)點：
    3G三螺杆泵(bèng)包括3G 通用型(xíng)，3GC船用型及特(te)殊型。3G三螺杆(gǎn)泵是轉子式(shì)容積泵，由于(yú)主動螺杆與(yu)從動螺杆上(shang)螺旋槽相互(hu)齧合及它們(men)與襯套三孔(kong)内表面的配(pèi)合，得以在泵(beng)的進出口之(zhī)間 形成數級(jí)動密封腔室(shi),這些動密封(fēng)腔室将不斷(duan)把液體由泵(beng)進口軸向移(yi)動到泵出口(kǒu)，并使所輸 液(yè)體逐級升壓(yā)，從而形成一(yī)個連續、平穩(wen)、軸向移動的(de)壓力液體。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(sān)螺杆泵适用(yòng)介質及性能(neng)範圍：3 g three-screw pump applicable medium range and performance
   3G三螺杆(gan)泵所輸液體(tǐ)為各種不含(han)固體顆粒，無(wu)腐蝕性油類(lèi)及類似油的(de)潤滑性液體(tǐ)，所輸液體粘(zhān)度為1.2~100°E（3.0~760cst），高粘度(dù)液體亦可通(tōng)過加溫降粘(zhan)後輸送。 流量(liàng)範圍0.2~590m3/h，最高工(gōng)作壓力100bar，最高(gāo)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(gǎn)泵結構:
  1、結構(gòu)簡單：具有多(duō)種結構形式(shì)，一般小流量(liang)0.2~6.5m3/h，泵的泵體和(hé)襯套合為一(yi)體（統稱泵體(ti)），軸封為機械(xiè)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(liu)量以上的泵(bèng)襯套為一單(dān)獨的零件固(gu)定于泵體内(nèi)，大流量泵多(duo)制成雙吸結(jié)構卧式安裝(zhuāng)，軸封根據輸(shu)送介質的不(bú)同有機械密(mì)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(yong)泵的安裝形(xíng)式有卧式和(hé)立式兩種，原(yuan)動機為交、直(zhí)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(san)螺杆泵的主(zhǔ)動螺杆由電(diàn)動機驅動，主(zhu)、從杆之間沒(méi)有機械接觸(chu)，而由所輸壓(ya)力液體驅使(shi)從杆繞軸心(xin)線自轉，主、從(cong)杆之間、螺杆(gǎn)與襯套之間(jiān)皆有一層油(yóu)膜保護，因而(er)泵的機械摩(mo)擦極小，壽命(ming)堪稱半永久(jiu)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(tǐ)在3G三螺杆泵(beng)内作軸向勻(yún)速直線運動(dong)，故壓力脈動(dòng)小，流量穩定(dìng)，噪音低，由于(yu)轉動部件慣(guàn)性小，則起動(dòng)力矩和振動(dong)很小。
  4、3G三螺杆(gǎn)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(bao)證3G三螺杆泵(beng)、電機及管路(lù)系統的安全(quán)，中等流量以(yi)上的螺杆泵(beng)均帶有安全(quán)閥，當壓力超(chao)過安全閥的(de)設定壓力時(shí)，高壓油将回(hui)流至泵的進(jìn)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.
