●特點：
    3g三(sān)螺杆泵包括(kuò)3g 通用型(xíng)，3gc船用型及特殊型。3g三螺杆泵是(shì)轉子(zǐ)式(shì)容積(jī)泵(bèng)，由于(yú)主動(dòng)螺杆(gǎn)與從(cóng)動(dòng)螺杆上螺旋(xuán)槽相互齧(niè)合及它們與襯(chèn)套三(sān)孔内表面(miàn)的配合，得以在(zài)泵的(de)進出口之(zhī)間 形成數級動(dòng)密封(fēng)腔室(shì),這些(xiē)動密封腔室将(jiāng)不斷(duàn)把液(yè)體由泵進口(kǒu)軸向移動到(dào)泵出口，并(bìng)使所(suǒ)輸 液(yè)體逐級升(shēng)壓，從而形(xíng)成一個連續、平(píng)穩、軸向(xiàng)移動的(de)壓力液體(tǐ)。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三螺杆泵适用介質(zhì)及性能範(fàn)圍(wéi)：3 g three-screw pump applicable medium range and performance
   3g三螺杆泵所(suǒ)輸液(yè)體為各(gè)種不含(hán)固體(tǐ)顆粒，無腐(fǔ)蝕性油類及類(lèi)似油的(de)潤(rùn)滑(huá)性(xìng)液體，所輸(shū)液體(tǐ)粘度為1.2~100°e（3.0~760cst），高粘度(dù)液體亦可通過加溫(wēn)降粘後輸(shū)送。 流量範圍0.2~590m3/h，最高工(gōng)作壓(yā)力100bar，最(zuì)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(jié)構:
  1、結構簡(jiǎn)單：具有多種結(jié)構形式，一般(bān)小(xiǎo)流量0.2~6.5m3/h，泵的(de)泵體(tǐ)和襯套(tào)合為一(yī)體（統稱泵(bèng)體），軸(zhóu)封為(wéi)機械密封(fēng)。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(liú)量以上(shàng)的泵(bèng)襯套(tào)為一(yī)單獨的(de)零件固(gù)定于(yú)泵體内，大(dà)流(liú)量泵多(duō)制成(chéng)雙吸結(jié)構(gòu)卧式(shì)安裝，軸封(fēng)根據(jù)輸送介(jiè)質的不(bú)同有機械密封和(hé)填(tián)料密封兩(liǎng)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(xíng)式有(yǒu)卧式和立(lì)式兩種，原動機為(wéi)交(jiāo)、直流(liú)船(chuán)用電動機。3 g marine pump installations have horizontal and vertical two kinds, prime mover for marine ac or dc motor.
  2、壽(shòu)命長(zhǎng)：3g三螺杆泵(bèng)的主動螺(luó)杆由(yóu)電動(dòng)機驅動，主(zhǔ)、從杆(gǎn)之(zhī)間(jiān)沒有(yǒu)機(jī)械接(jiē)觸，而由(yóu)所輸壓力液體(tǐ)驅使從杆繞軸心線自轉(zhuǎn)，主、從杆之(zhī)間、螺(luó)杆與(yǔ)襯套之間皆有(yǒu)一層油膜(mó)保護(hù)，因而(ér)泵的機械(xiè)摩擦(cā)極小，壽命堪稱半永(yǒng)久性(xìng)。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、所輸液體在3g三(sān)螺杆泵内作軸(zhóu)向勻(yún)速直(zhí)線運(yùn)動，故壓力(lì)脈動小，流(liú)量穩定，噪(zào)音低(dī)，由(yóu)于(yú)轉動(dòng)部件(jiàn)慣性(xìng)小，則起動力矩和振動很(hěn)小(xiǎo)。
  4、3g三(sān)螺杆(gǎn)泵具有高吸入能力。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、為保證3g三(sān)螺杆泵、電機及管路(lù)系統(tǒng)的安(ān)全，中等(děng)流量以上的(de)螺杆(gǎn)泵均帶(dài)有安全閥，當(dāng)壓力(lì)超過安全(quán)閥的設定(dìng)壓力時，高壓油将回(huí)流至泵的進油(yóu)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.
