    ●雙螺杆泵有密封(feng)式和不密封式兩(liǎng)種類型，按介質從(cong)一🔴端還是 從兩端(duan)進入齧合空間，雙(shuāng)螺杆又被分為雙(shuang)吸式和單🧡吸式兩(liǎng)種結構。雙螺杆泵(bèng)是外齧合✉️的螺杆(gǎn)🔅泵，它利用相互齧(niè)合，互不接觸的兩(liǎng)根螺杆來抽送液(ye)🔞體。雙螺杆泵為一(yī)種雙吸式非密閉(bì)的雙🏃‍♀️螺杆泵。一端(duan)伸出泵外的主動(dong)螺杆由原動機驅(qū)動。主動螺杆與從(cóng)動螺杆具有不同(tong)旋向的螺紋。螺杆(gan)與泵體緊密貼合(hé)☂️。從動螺⭐杆是通過(guo)同步齒輪由主動(dòng)螺杆帶動的。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(luó)杆泵作為一種容(róng)積式泵，泵内吸入(ru)室應與排出室嚴(yán)密地隔開。因此，泵(beng)體與螺杆外圓表(biao)面及螺杆與🧑🏽‍🤝‍🧑🏻螺杆(gǎn)間隙🌈應盡⚽可能小(xiǎo)些。同時螺杆與泵(beng)體、螺杆與螺杆間(jiān)又相互形成密封(feng)腔，保證密閉，否則(zé)就可能有液體從(cóng)間隙中倒流回去(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.

    ●雙螺杆泵可分為(wéi)内置軸承和外置(zhì)軸承兩種形式。在(zài)内置⭐軸承的結構(gou)型式中軸承由輸(shu)送物進行潤滑。外(wai)置軸承結構的雙(shuang)螺杆泵工作腔同(tóng)軸承是分開的。由(you)于這種泵的結構(gou)和螺杆間存在的(de)側間隙🚶，它可以輸(shū)送非潤滑性介質(zhi)。此外，調整同步齒(chǐ)輪使得螺杆不接(jiē)觸，同時将輸出扭(niǔ)矩的一半傳給從(cong)動📧螺杆。正如所有(yǒu)螺杆泵一樣，外✌️置(zhì)軸承式雙螺杆泵(beng)也有自吸能力，而(ér)且多數泵輸送元(yuán)件本身都是雙吸(xi)對稱布置，可消除(chú)軸向力，也有很大(da)的吸高。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.

    ●雙螺杆泵(bèng)系列産品分為單(dan)吸雙螺杆泵和雙(shuang)吸雙🔴螺杆泵兩大(dà)類。該系列産品具(jù)有特殊的螺杆型(xing)線和與之配🍉套的(de)特殊結構，廣泛适(shì)用于石油、化工、冶(yě)金、鋼鐵、電力、船🚩舶(bo)、制藥、食品、建材等(děng)各♈種行業，其适⭐用(yong)介質之多、輸送範(fàn)😍圍之廣、應用工況(kuàng)之複雜是其它泵(bèng)類産品⚽無法比拟(nǐ)的。這些特點也🧑🏾‍🤝‍🧑🏼使(shi)得該系列泵具有(yǒu)潛在的使用發展(zhǎn)前景。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(you)兩根左、有施單頭(tóu)螺紋的螺杆，主動(dòng)螺杆2由動力機驅(qū)動轉動時，靠同步(bu)齒輪1帶動從動螺(luo)杆3轉動。兩根螺杆(gǎn)以及螺杆與泵體(ti). 之間存在着間隙(xi)，該間隙靠齒輪和(hé)軸承保證。其間隙(xi)大小，取🈲決于液體(tǐ)粘度、工作壓力等(děng)因素。由于每根螺(luo)杆兩端螺紋的旋(xuan)向相反，螺杆轉動(dong)時，由螺杆㊙️齧合線(xian)形成的泵工作腔(qiāng)。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(xi)式結構，螺杆兩端(duan)處于同一壓力腔(qiāng)㊙️中，軸向力可以自(zi)行平衡。兩端軸承(cheng)采用外裝式，單獨(du)采用潤滑油(脂)潤(run)滑，因而不受輸送(song)介質的影響。兩螺(luó)杆間用一對🏃同步(bù)齒輪驅動，螺杆齒(chi)面間并不接觸，而(er)留有一微小間隙(xi)，介質中的雜質并(bing)❌不能對螺杆齒面(miàn)産生直接的磨損(sun)(除沖刷外)。 除一些(xie)小排量泵外(2W.W4.0以下(xia))，一般在泵體上都(dōu)帶有内流式安全(quan)閥，當排放壓力超(chao)過✊額定🧡值時，有一(yi)定的保護作用。 泵(bèng)體上的進出口方(fang)向有兩種，一為水(shui)平進，水平出;二為(wei)水平進，垂直向上(shàng)出;用戶可根據自(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.
