●特點：
    3G三(san)螺杆泵包(bāo)括3G 通用型(xing)，3GC船用型及(ji)特殊型。3G三(sān)螺杆泵是(shì)轉子式容(róng)積泵，由于(yú)主動螺杆(gǎn)與從動螺(luó)杆上螺旋(xuan)槽相互齧(nie)合及它們(men)與襯套三(sān)孔内表面(mian)的配合，得(dé)以在泵的(de)進出口之(zhī)間 形成數(shù)級動密封(feng)腔室,這些(xie)動密封腔(qiāng)室将不斷(duàn)把液體由(yóu)泵進口軸(zhou)向移動到(dào)泵出口，并(bìng)使所輸 液(yè)體逐級升(shēng)壓，從而形(xíng)成一個連(lian)續、平穩、軸(zhou)向移動的(de)壓力液體(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三螺杆泵(beng)适用介質(zhì)及性能範(fàn)圍：3 g three-screw pump applicable medium range and performance
   3G三螺杆(gan)泵所輸液(ye)體為各種(zhǒng)不含固體(tǐ)顆粒，無腐(fǔ)蝕性油類(lèi)及類似油(you)的潤滑性(xìng)液體，所輸(shu)液體粘度(dù)為1.2~100°E（3.0~760cst），高粘度(du)液體亦可(kě)通過加溫(wen)降粘後輸(shu)送。 流量範(fan)圍0.2~590m3/h，最高工(gong)作壓力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(jie)構:
  1、結構簡(jiǎn)單：具有多(duo)種結構形(xíng)式，一般小(xiǎo)流量0.2~6.5m3/h，泵的(de)泵體和襯(chèn)套合為一(yi)體（統稱泵(beng)體），軸封為(wei)機械密封(feng)。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.
  中等流量(liàng)以上的泵(bèng)襯套為一(yī)單獨的零(ling)件固定于(yú)泵體内，大(da)流量泵多(duō)制成雙吸(xī)結構卧式(shì)安裝，軸封(feng)根據輸送(song)介質的不(bu)同有機械(xie)密封和填(tián)料密封兩(liang)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(xing)式有卧式(shi)和立式兩(liang)種，原動機(ji)為交、直流(liu)船用電動(dong)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(beng)的主動螺(luo)杆由電動(dòng)機驅動，主(zhǔ)、從杆之間(jian)沒有機械(xiè)接觸，而由(you)所輸壓力(lì)液體驅使(shǐ)從杆繞軸(zhou)心線自轉(zhuan)，主、從杆之(zhi)間、螺杆與(yǔ)襯套之間(jian)皆有一層(céng)油膜保護(hù)，因而泵的(de)機械摩擦(ca)極小，壽命(mìng)堪稱半永(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、所輸(shu)液體在3G三(sān)螺杆泵内(nei)作軸向勻(yun)速直線運(yun)動，故壓力(li)脈動小，流(liu)量穩定，噪(zao)音低，由于(yú)轉動部件(jiàn)慣性小，則(ze)起動力矩(ju)和振動很(hen)小。
  4、3G三螺杆(gan)泵具有高(gāo)吸入能力(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(san)螺杆泵、電(dian)機及管路(lu)系統的安(an)全，中等流(liu)量以上的(de)螺杆泵均(jun)帶有安全(quan)閥，當壓力(li)超過安全(quán)閥的設定(ding)壓力時，高(gāo)壓油将回(huí)流至泵的(de)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.
