    ●雙螺杆泵有密封式和不密封式(shì)兩種類型，按介質從一端還是(shì) 從(cóng)兩端進(jìn)入齧合空間，雙螺杆又被分為雙(shuāng)吸式和單吸式兩種結構。雙螺杆泵是外齧(niè)合的(de)螺杆泵，它利用相互(hù)齧(niè)合，互不(bú)接觸的兩(liǎng)根螺杆來(lái)抽送(sòng)液體。雙螺杆泵為一種雙吸式非密(mì)閉的雙螺杆泵。一端伸出泵外(wài)的主動螺杆(gǎn)由原動機驅動。主動螺杆與從動螺杆(gǎn)具有不同旋向的螺紋。螺(luó)杆與泵體緊密貼合。從動螺杆是通過同步齒(chǐ)輪由(yóu)主動螺杆帶動的。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.

    ●雙螺杆泵作為一種容積式泵，泵内吸(xī)入室應與排出室嚴密地隔開。因此，泵體與螺杆外圓表面及螺杆與螺杆間(jiān)隙應盡可能小些。同(tóng)時螺杆與泵(bèng)體、螺杆與螺杆(gǎn)間又相互形成密封腔，保證(zhèng)密閉，否則就可能有液體從間隙中倒(dǎo)流回去。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(bèng)可分(fèn)為内置(zhì)軸承和外置軸承兩種(zhǒng)形式(shì)。在内置軸承的結構型式(shì)中軸承由(yóu)輸送物進行潤滑。外(wài)置軸承結構的(de)雙螺(luó)杆泵工作腔同軸承是分開的。由于這種泵的結構和螺杆間存在的側(cè)間隙，它可(kě)以(yǐ)輸送非潤滑性介(jiè)質。此外，調整同步(bù)齒輪使得螺杆不(bú)接觸(chù)，同時将輸出(chū)扭矩的一半傳給從動螺(luó)杆。正如所有螺杆泵一樣，外(wài)置軸承式雙螺杆(gǎn)泵也(yě)有自吸能力，而(ér)且多數泵輸送元件本身都是(shì)雙(shuāng)吸對稱布置，可消(xiāo)除軸向力，也有很(hěn)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.

    ●雙螺杆泵系列産品分為(wéi)單吸雙螺杆泵和雙吸雙(shuāng)螺杆泵兩(liǎng)大類。該系列産品具有特殊的螺杆型線(xiàn)和與之配套的特殊結構，廣泛(fàn)适用于石油、化工、冶金、鋼(gāng)鐵、電力、船舶、制藥、食品、建(jiàn)材等各種行業，其适用介(jiè)質之多、輸送範圍(wéi)之廣、應用工況之(zhī)複雜是其它泵類産品無法比(bǐ)拟的。這些(xiē)特點也使得該系列(liè)泵具有潛在的使用(yòng)發展前景(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.

    ●泵體内裝有兩根左、有施單(dān)頭螺紋的螺杆，主動螺(luó)杆2由動力機驅動轉(zhuǎn)動時，靠同步齒輪1帶動從(cóng)動螺杆3轉動。兩根螺(luó)杆以及螺杆與泵體. 之間存在着間隙，該間隙靠齒輪和軸承保證。其間(jiān)隙大小，取決于液體粘度、工作壓力等因素。由于每根(gēn)螺杆兩端螺紋的旋向相反，螺杆轉動時，由螺杆齧合(hé)線形成的泵工作腔。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.

   ●該型泵采用雙吸式結構，螺杆兩端處于(yú)同一壓力腔中，軸向力可(kě)以自行平衡。兩(liǎng)端軸承采用外裝式(shì)，單獨采用潤滑油(脂)潤滑，因而不受輸送介質的影響。兩螺杆(gǎn)間用一對同步齒輪驅動，螺杆齒面間并不接觸，而留(liú)有一微小間隙，介質中的雜質并不能對螺杆齒(chǐ)面産生直接的磨損(除沖刷外)。 除一(yī)些小排量泵外(2W.W4.0以(yǐ)下)，一般(bān)在(zài)泵體上都帶有内(nèi)流式安全閥，當排放壓力超過額定值時，有一定的保(bǎo)護作用(yòng)。 泵體上的進出口方向有兩種，一為水平進，水平出;二為水平進，垂直向上出;用戶可根據自己需要選擇。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.
