    ●雙(shuāng)螺杆泵(bèng)有(yǒu)密封(fēng)式和(hé)不密封式(shì)兩種(zhǒng)類型，按介(jiè)質從一端(duān)還是(shì) 從兩端進(jìn)入齧(niè)合空間(jiān)，雙螺杆又被分(fèn)為(wéi)雙吸(xī)式和單(dān)吸式兩(liǎng)種結構。雙(shuāng)螺杆泵是外齧合的螺杆泵，它(tā)利用相互(hù)齧(niè)合(hé)，互不接觸的兩(liǎng)根螺(luó)杆來(lái)抽送液體(tǐ)。雙螺杆泵(bèng)為一種雙(shuāng)吸式(shì)非密(mì)閉的(de)雙螺杆泵。一(yī)端(duān)伸出泵外(wài)的主動(dòng)螺杆由原動機驅(qū)動。主(zhǔ)動螺杆與從動(dòng)螺杆具有不同旋(xuán)向的螺紋。螺(luó)杆與(yǔ)泵體緊密(mì)貼合(hé)。從動(dòng)螺杆是通(tōng)過同(tóng)步齒(chǐ)輪由(yóu)主動螺杆(gǎn)帶動的。double screw pump has sealed and not enclosed two types, according to the medium from the side or from both ends into space meshing, double screw was divided into double suction type and structure of single suction type two kinds.screw pump, twin screw pump is the external gear utilizing the mesh each other, mutual contact of two screw to pumping liquid.double screw pump is a kind of double suction not airtight double screw pump.active outside the side out of the pump screw driven by a prime mover.driving screw and driven screw thread with different handedness.screw pump body and tightly.driven screw is driven by synchronous gear by the active screw.

    ●雙螺杆(gǎn)泵作為一種容(róng)積式(shì)泵，泵内吸入室應與排出(chū)室嚴(yán)密地隔開(kāi)。因此，泵體(tǐ)與螺杆外(wài)圓表面及(jí)螺杆(gǎn)與螺(luó)杆間(jiān)隙應(yīng)盡可能小(xiǎo)些。同時螺杆與泵體(tǐ)、螺杆與螺(luó)杆間又相(xiàng)互形(xíng)成密(mì)封(fēng)腔(qiāng)，保證(zhèng)密閉，否則就可(kě)能有(yǒu)液(yè)體從間(jiān)隙中倒(dǎo)流回去(qù)。double screw pump as a positive displacement pump, the pump suction chamber should be closely separated and discharge chamber inside.therefore, the pump body and screw cylindrical surface and screw and screw clearance should be as small as possible.screw pump body and at the same time, each other between the screw and screw and form a sealed chamber, ensure airtight, otherwise there may be liquid backflow from the gap.

    ●雙螺(luó)杆泵可(kě)分(fèn)為内置軸承和(hé)外置軸(zhóu)承兩種形式。在内(nèi)置軸(zhóu)承的(de)結構型式(shì)中軸承由(yóu)輸(shū)送物進行潤滑。外(wài)置軸承結構的(de)雙螺(luó)杆(gǎn)泵(bèng)工作(zuò)腔同軸承(chéng)是分(fèn)開的。由(yóu)于這種(zhǒng)泵的結構和螺(luó)杆間存(cún)在的側間隙，它可(kě)以輸(shū)送非潤滑性介(jiè)質。此外，調整同(tóng)步齒輪使(shǐ)得螺(luó)杆不接(jiē)觸，同時将輸出扭(niǔ)矩的(de)一半傳給(gěi)從動螺杆(gǎn)。正(zhèng)如(rú)所有螺杆(gǎn)泵一樣，外(wài)置軸(zhóu)承式(shì)雙螺(luó)杆泵(bèng)也有(yǒu)自吸(xī)能力(lì)，而且多數(shù)泵輸送元件(jiàn)本身都是雙吸對(duì)稱布置，可消除(chú)軸向(xiàng)力，也有很(hěn)大(dà)的(de)吸高(gāo)。double screw pump can be divided into internal bearing and the outer bearing two forms.in the built-in bearing structure bearing lubrication by conveying material.working with external bearing structure of the double screw pump bearings are separated.owing to the pump structure and side clearance between screw, it can transport non-lubricative medium.in addition, the adjustment of the synchronous gear makes the screw does not contact, at the same time the output torque of the half to driven screw.like all of the screw pump, external bearing type twin-screw pump, and most are double suction pump element itself symmetric arrangement, can eliminate the axial force, also has a lot of high absorption.

    ●雙螺(luó)杆泵(bèng)系列産品(pǐn)分為單(dān)吸(xī)雙螺杆泵和(hé)雙吸雙(shuāng)螺杆泵兩大類(lèi)。該系(xì)列(liè)産品具(jù)有特殊的螺(luó)杆(gǎn)型線(xiàn)和與之配(pèi)套的特殊結構，廣泛(fàn)适用(yòng)于石油、化工(gōng)、冶金、鋼(gāng)鐵、電(diàn)力、船(chuán)舶、制(zhì)藥、食(shí)品(pǐn)、建材等各種(zhǒng)行業，其适用介質之多、輸(shū)送(sòng)範(fàn)圍之廣、應(yīng)用工況之(zhī)複雜(zá)是其它泵(bèng)類産(chǎn)品無法比(bǐ)拟的。這些(xiē)特點也使(shǐ)得該(gāi)系列泵具(jù)有潛(qián)在(zài)的使(shǐ)用發展(zhǎn)前景(jǐng)。double screw pump series products are divided into single suction of two kinds of double screw pump and double suction double screw pump.this series of products have special screw lines and form a complete set with the special structure, widely used in petroleum, chemical industry, metallurgy, steel, electricity, shipbuilding, pharmaceutical, food, building materials and other industries, by as much as its applicable medium, transmission range wide, application condition of the complex is unmatched by other pump product.these features also makes the use of this series of pumps with potential development prospects.

    ●泵體内裝有(yǒu)兩根左(zuǒ)、有施單頭(tóu)螺紋(wén)的螺杆(gǎn)，主動螺(luó)杆2由動力(lì)機驅動轉動時(shí)，靠同(tóng)步齒(chǐ)輪(lún)1帶(dài)動從動螺(luó)杆(gǎn)3轉動。兩根螺杆以(yǐ)及螺(luó)杆與(yǔ)泵體. 之間(jiān)存在着間隙，該(gāi)間隙靠齒輪和(hé)軸承保證(zhèng)。其間(jiān)隙大(dà)小，取決于(yú)液體粘度、工作(zuò)壓力等因素。由(yóu)于每根(gēn)螺杆兩端螺紋(wén)的旋向(xiàng)相反(fǎn)，螺杆轉動(dòng)時，由(yóu)螺杆齧合線形成的(de)泵工(gōng)作腔。equipped with two left in the pump body, a single thread screw, active screw driven by engine 2 turns, driven by synchronous gear 1 driven screw 3 rotation.two screw and screw and pump body. there is a gap between the gap by gear and bearing.the gap size, depends on the liquid viscosity, pressure and other factors.because each thread rotate to the opposite on both ends of the screw, the screw rotates, formed by the screw meshing line pump working chamber.

   ●該型泵采用雙吸式(shì)結構(gòu)，螺杆兩端(duān)處于(yú)同一壓力(lì)腔(qiāng)中(zhōng)，軸向(xiàng)力可(kě)以自(zì)行平(píng)衡。兩(liǎng)端軸(zhóu)承采用外(wài)裝式，單獨采用潤滑(huá)油(脂)潤滑(huá)，因而(ér)不受輸(shū)送介質(zhì)的影(yǐng)響。兩(liǎng)螺杆(gǎn)間用(yòng)一對(duì)同步(bù)齒(chǐ)輪驅動，螺杆(gǎn)齒面間并不(bú)接觸，而(ér)留有(yǒu)一微(wēi)小間隙，介(jiè)質中的雜(zá)質并不能(néng)對(duì)螺杆齒面産生直接的磨損(除沖刷(shuā)外(wài))。 除一些小(xiǎo)排(pái)量泵外(wài)(2w.w4.0以下(xià))，一般(bān)在泵體上都(dōu)帶有内(nèi)流式(shì)安全閥(fá)，當排放壓力(lì)超過(guò)額定值時，有一定的保護作用(yòng)。 泵體上的進出(chū)口方向(xiàng)有兩種(zhǒng)，一為水平(píng)進，水(shuǐ)平出(chū);二為水平進，垂直向上出(chū);用戶可根(gēn)據自(zì)己需要選擇。this type pump adopts double suction type structure, at the same pressure in the cavity on both ends of the screw, the axial force can balance itself.both ends of bearing mounted outside using, lubricated by lubricating oil (grease) separately, and therefore not affected by the medium.with a pair of synchronous gears drive between the two screw, the screw does not contact between tooth surfaces, and leave a small gap, the impurities in medium can not be directly on the screw tooth surface wear (except wash).except a few small displacement pump (below 2 w. w4.0), generally contain flow relief valve on the pump body, when the discharge pressure exceeds rating, has certain protective effect.there are two kinds of the direction of the import and export on the pump body, one for level, level;secondly, level, vertical;user can choose according to their own needs.
