●特點(diǎn)：
    3g三(sān)螺杆(gǎn)泵包(bāo)括(kuò)3g 通用型，3gc船用(yòng)型及(jí)特殊(shū)型。3g三螺杆泵是(shì)轉子式容積泵(bèng)，由于主動螺杆(gǎn)與從動(dòng)螺杆上(shàng)螺旋(xuán)槽相互齧(niè)合(hé)及它(tā)們與襯(chèn)套三孔内表面(miàn)的配合，得(dé)以在(zài)泵的進(jìn)出口之(zhī)間 形成數級動密(mì)封(fēng)腔室(shì),這些(xiē)動密封(fēng)腔(qiāng)室将(jiāng)不斷把(bǎ)液(yè)體由(yóu)泵進口(kǒu)軸向移動到(dào)泵出(chū)口，并使(shǐ)所(suǒ)輸 液體逐(zhú)級升壓，從而形(xíng)成一個連續、平穩、軸向移動的壓力液體(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(luó)杆泵适用(yòng)介質(zhì)及性能範圍：3 g three-screw pump applicable medium range and performance
   3g三螺杆(gǎn)泵所(suǒ)輸液體為各種不含(hán)固體(tǐ)顆粒，無腐(fǔ)蝕性油類及類(lèi)似油(yóu)的潤(rùn)滑性液體，所輸(shū)液體(tǐ)粘度(dù)為1.2~100°e（3.0~760cst），高粘度(dù)液體(tǐ)亦可(kě)通過加溫降粘後輸(shū)送。 流量範圍(wéi)0.2~590m3/h，最(zuì)高工作壓(yā)力100bar，最(zuì)高溫度(dù)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(gòu):
  1、結構簡(jiǎn)單：具有多種結(jié)構形式，一般小流量0.2~6.5m3/h，泵的(de)泵體和襯(chèn)套合為一(yī)體（統稱泵(bèng)體），軸(zhóu)封為機(jī)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(liàng)以上(shàng)的泵(bèng)襯套(tào)為一(yī)單獨(dú)的零(líng)件固(gù)定于泵(bèng)體(tǐ)内，大流量泵多制成(chéng)雙吸結構卧式安裝，軸封根據(jù)輸送介質的不(bú)同有機械(xiè)密封(fēng)和填料密封兩(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船用泵的安(ān)裝形式有(yǒu)卧式(shì)和立式(shì)兩(liǎng)種，原(yuán)動機(jī)為(wéi)交、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、壽命長(zhǎng)：3g三螺杆泵的主動(dòng)螺杆由(yóu)電動機驅(qū)動，主(zhǔ)、從杆之間沒有機械接觸，而由(yóu)所輸壓(yā)力(lì)液體驅使從杆(gǎn)繞軸(zhóu)心線自轉，主、從(cóng)杆之間、螺(luó)杆與(yǔ)襯套之間皆有(yǒu)一層油膜保護(hù)，因而泵的機械摩擦極小，壽命(mìng)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(suǒ)輸液體在3g三(sān)螺杆泵(bèng)内(nèi)作軸(zhóu)向勻速直線運(yùn)動，故壓(yā)力(lì)脈動(dòng)小，流(liú)量穩定，噪音(yīn)低，由(yóu)于轉動(dòng)部件慣性小，則(zé)起動力(lì)矩和振(zhèn)動很小(xiǎo)。
  4、3g三(sān)螺杆(gǎn)泵具有高(gāo)吸入(rù)能力(lì)。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(diàn)機及(jí)管路(lù)系統的安(ān)全，中(zhōng)等流量以(yǐ)上的(de)螺杆泵均(jun1)帶有安全閥，當(dāng)壓力超過安全(quán)閥的設定(dìng)壓力時，高壓(yā)油(yóu)将回(huí)流至泵的進油口(kǒu)。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.
