●特點：
    3G三(san)螺杆泵(bèng)包括3G 通(tong)用型，3GC船(chuán)用型及(ji)特殊型(xíng)。3G三螺杆(gan)泵是轉(zhuan)子式容(rong)積泵，由(yóu)于主動(dong)螺杆與(yǔ)從動螺(luó)杆上螺(luo)旋槽相(xiang)互齧合(hé)及它們(men)與襯套(tao)三孔内(nei)表面的(de)配合，得(de)以在泵(beng)的進出(chū)口之間(jian) 形成數(shù)級動密(mi)封腔室(shì),這些動(dòng)密封腔(qiang)室将不(bu)斷把液(yè)體由泵(beng)進口軸(zhou)向移動(dòng)到泵出(chu)口，并使(shi)所輸 液(yè)體逐級(jí)升壓，從(cóng)而形成(cheng)一個連(lián)續、平穩(wěn)、軸向移(yi)動的壓(yā)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(gan)泵适用(yong)介質及(jí)性能範(fàn)圍：3 g three-screw pump applicable medium range and performance
   3G三螺(luo)杆泵所(suo)輸液體(ti)為各種(zhong)不含固(gù)體顆粒(lì)，無腐蝕(shí)性油類(lèi)及類似(sì)油的潤(rùn)滑性液(yè)體，所輸(shū)液體粘(zhān)度為1.2~100°E（3.0~760cst），高(gāo)粘度液(yè)體亦可(kě)通過加(jiā)溫降粘(zhān)後輸送(song)。 流量範(fàn)圍0.2~590m3/h，最高(gāo)工作壓(yā)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(sān)螺杆泵(bèng)結構:
  1、結(jie)構簡單(dān)：具有多(duo)種結構(gòu)形式，一(yi)般小流(liu)量0.2~6.5m3/h，泵的(de)泵體和(he)襯套合(he)為一體(tǐ)（統稱泵(beng)體），軸封(feng)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(zhong)等流量(liàng)以上的(de)泵襯套(tào)為一單(dān)獨的零(ling)件固定(ding)于泵體(tǐ)内，大流(liú)量泵多(duō)制成雙(shuang)吸結構(gòu)卧式安(an)裝，軸封(feng)根據輸(shū)送介質(zhi)的不同(tong)有機械(xiè)密封和(he)填料密(mì)封兩種(zhǒng)。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(zhuāng)形式有(yǒu)卧式和(he)立式兩(liǎng)種，原動(dòng)機為交(jiao)、直流船(chuán)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(mìng)長：3G三螺(luo)杆泵的(de)主動螺(luó)杆由電(diàn)動機驅(qū)動，主、從(cóng)杆之間(jiān)沒有機(ji)械接觸(chu)，而由所(suǒ)輸壓力(li)液體驅(qū)使從杆(gǎn)繞軸心(xīn)線自轉(zhuǎn)，主、從杆(gan)之間、螺(luó)杆與襯(chèn)套之間(jian)皆有一(yī)層油膜(mo)保護，因(yīn)而泵的(de)機械摩(mo)擦極小(xiǎo)，壽命堪(kān)稱半永(yong)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(suo)輸液體(ti)在3G三螺(luó)杆泵内(nèi)作軸向(xiàng)勻速直(zhi)線運動(dòng)，故壓力(li)脈動小(xiao)，流量穩(wen)定，噪音(yīn)低，由于(yu)轉動部(bù)件慣性(xìng)小，則起(qi)動力矩(ju)和振動(dòng)很小。
  4、3G三(san)螺杆泵(bèng)具有高(gao)吸入能(néng)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(luo)杆泵、電(diàn)機及管(guan)路系統(tong)的安全(quan)，中等流(liu)量以上(shàng)的螺杆(gǎn)泵均帶(dài)有安全(quan)閥，當壓(yā)力超過(guò)安全閥(fa)的設定(ding)壓力時(shi)，高壓油(you)将回流(liú)至泵的(de)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.
