    ●雙(shuāng)螺杆泵有密封(fēng)式和不密封式(shi)兩種類型，按介(jiè)質從一端還是(shì) 從兩端進入齧(niè)合空間，雙螺杆(gan)又被分為雙吸(xī)式和單🙇🏻吸式兩(liǎng)種結構。雙螺杆(gǎn)泵是外齧合的(de)螺杆泵，它利用(yong)相互齧合，互🈲不(bú)接觸的兩根螺(luo)杆來抽送液體(ti)。雙螺杆泵為一(yi)種雙吸式非密(mì)閉的雙螺杆泵(bèng)。一端伸出泵外(wài)的主動螺杆由(you)原動機驅動。主(zhu)動螺杆與從動(dong)螺杆具有不同(tong)旋向的螺紋。螺(luó)杆與泵體緊📧密(mi)貼合。從動螺杆(gan)是通過同步齒(chi)輪由主動👌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)積式泵，泵内吸(xī)入室應與排出(chū)室👌嚴密地隔開(kāi)。因此，泵體與螺(luó)杆外圓表面及(jí)螺✔️杆與螺杆間(jian)隙應盡可能小(xiao)些。同時螺杆與(yu)泵體、螺杆與螺(luó)杆間又相互形(xing)成密封腔，保證(zhèng)密閉，否則就可(ke)能有液體從間(jiān)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(fèn)為内置軸承和(he)外置軸承兩種(zhǒng)形式♉。在💃🏻内🏃🏻置軸(zhou)承的結構型式(shì)中軸承由輸送(sòng)物進行潤滑。外(wai)置軸承結構的(de)雙螺杆泵工作(zuò)腔同軸承是分(fen)🌈開的。由🌂于這種(zhong)🏃泵的結構和螺(luó)杆間存在的側(cè)間隙✔️，它可以輸(shu)送非潤滑性介(jiè)質。此外，調整同(tóng)步齒輪使✉️得螺(luó)杆不接觸，同時(shi)将輸出扭矩的(de)一♈半傳給從動(dong)螺杆。正如所有(yǒu)螺杆泵一樣，外(wài)置軸承式雙螺(luo)杆泵也有自吸(xī)能力，而且多數(shù)泵輸送元件本(ben)身都是雙🏃‍♂️吸對(dui)稱布置，可消除(chu)軸向力，也有很(hen)大的🐆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(luó)杆泵系列産品(pin)分為單吸雙螺(luó)杆泵和雙吸雙(shuang)螺杆泵兩大類(lei)。該系列産品具(ju)有特殊的螺杆(gǎn)型線和與之配(pei)㊙️套的特殊結構(gou)🏃‍♂️，廣泛适用于石(shí)油、化工、冶金、鋼(gāng)鐵💞、電力、船舶、制(zhì)藥✉️、食品、建材等(děng)各種行業，其适(shì)用介質之多、輸(shu)送範圍之廣、應(ying)用工況之💜複雜(za)是其它泵類産(chǎn)品無法比拟的(de)🔆。這些特點也使(shi)得該系列✊泵具(ju)有潛在的使用(yong)發展前景。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(ti)内裝有兩根左(zuǒ)、有施單頭螺紋(wen)的螺杆，主動螺(luó)杆2由動力機驅(qū)動轉動時，靠同(tóng)步齒輪1帶動從(cóng)動螺杆3轉動。兩(liǎng)根螺杆以及螺(luó)杆與泵體. 之間(jiān)存在着間隙，該(gai)間隙靠齒輪和(hé)軸承保證。其間(jiān)⭐隙大小，取決🍉于(yú)液體粘度、工作(zuò)壓力等因素。由(yóu)于每根螺杆兩(liǎng)端螺紋的旋向(xiàng)相反，螺杆轉動(dòng)時，由螺杆齧合(hé)線形成的泵工(gong)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(cai)用雙吸式結構(gòu)，螺杆兩端處于(yu)同一壓力腔🥰中(zhong)，軸向力💃🏻可以自(zì)行平衡。兩端軸(zhóu)承采用外裝式(shi)，單獨采用潤滑(huá)油(脂)潤滑，因而(er)不受輸送介質(zhì)的影響。兩螺杆(gan)間用一對同步(bù)📐齒輪驅㊙️動，螺杆(gan)齒面間并不接(jie)觸，而留有一微(wei)小間隙，介質中(zhōng)🔆的雜質并不能(néng)對螺杆齒面産(chǎn)生直接的磨損(sǔn)(除沖刷外)。 除一(yī)些小排量泵外(wài)(2W.W4.0以下)，一般在泵(bèng)體上都帶有内(nei)流式安全閥，當(dang)排放壓力超過(guo)額定值時，有一(yi)定的保護作用(yòng)。 泵體上的進出(chu)口方向有兩種(zhong)，一為水平📱進，水(shui)平出;二為水平(píng)進，垂直向上出(chu);用戶可根據自(zi)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.
