    4, 1 ~ 3000 was/s, medium viscosity reducing speed can reach 106 was/s medium viscosity influence the performance of double screw pump, pump displacement refers to the specific viscosity of conditions in the name of the displacement, in order to ensure the pump can work in high efficiency, when the test is not sufficient, suggestion choice speed on the viscosity of the following terms and conditions: medium viscosity cSt speed r/min < 4001500 400 ~ 12001000, 1200 ~ 400.

    ●雙螺杆泵有(yǒu)密(mì)封式和不密封式(shì)兩種類型，按介質(zhì)從一端還是 從兩端進入齧合空間，雙螺杆(gǎn)又被分為雙吸式和單吸式兩(liǎng)種結構。雙螺杆(gǎn)泵是外齧合的(de)螺杆泵，它利用相互齧合，互不接觸的兩根螺杆來(lái)抽送液體。雙螺杆泵(bèng)為(wéi)一種雙(shuāng)吸式非密(mì)閉的雙螺(luó)杆泵。一端伸出泵外的主動螺杆由原動機驅動。主動螺杆與(yǔ)從動螺杆具有不同旋向的(de)螺紋。螺(luó)杆與泵體緊密(mì)貼合。從動螺杆是通(tōng)過同步齒(chǐ)輪由主(zhǔ)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(shuāng)螺杆泵作為一種容積式泵，泵内吸入室應(yīng)與排出室(shì)嚴密地隔開。因此(cǐ)，泵體與螺杆外圓表面及螺杆與螺杆間隙應(yīng)盡可能小些。同時(shí)螺杆與泵體、螺杆與螺杆間又相互形成密(mì)封腔，保證密閉，否(fǒu)則就(jiù)可能有液體從間隙中倒流回去。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.

    ●雙螺杆泵可分(fèn)為内置軸承和外(wài)置軸承兩種形式(shì)。在内置軸承的結構型式中軸承(chéng)由輸送物進行潤滑。外置軸承結構的雙螺(luó)杆泵工作腔(qiāng)同軸承是分(fèn)開的。由于這種泵的結構和螺杆間存在的側間隙，它可以(yǐ)輸送非潤(rùn)滑性介(jiè)質。此外，調整同步齒輪使得螺杆不接觸，同時将輸(shū)出扭矩的一半傳給從動螺杆。正如所有螺杆泵一樣，外(wài)置軸承式雙螺(luó)杆泵也(yě)有自吸能力，而且多數泵輸送元件本身都是雙吸對稱布置，可消除軸向力，也有很大的吸高。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(chǎn)品分為單吸雙螺杆泵和雙(shuāng)吸雙螺杆泵兩大類。該系列産品具有特殊的螺杆(gǎn)型線(xiàn)和與之配套的特殊結構，廣泛(fàn)适用于石油、化工(gōng)、冶(yě)金、鋼鐵、電力、船舶、制(zhì)藥、食品、建(jiàn)材等各種行業，其适用介質之(zhī)多、輸送範圍之廣、應用工況之複雜是其它泵類産品無法比拟的。這些(xiē)特點也(yě)使得該系列泵具有潛在的使用發(fā)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.

    ●泵體内裝有兩根左、有施單頭螺紋的螺杆，主(zhǔ)動螺(luó)杆2由動力機驅動轉動(dòng)時，靠同步齒輪1帶動從(cóng)動螺杆3轉動。兩根螺(luó)杆(gǎn)以及螺杆與(yǔ)泵體. 之間存在着間(jiān)隙，該間隙靠齒輪和軸承保證。其間隙大小，取決于(yú)液體粘度、工作壓力等因(yīn)素。由于每根螺杆兩端螺(luó)紋的旋向(xiàng)相反，螺杆轉動時，由螺杆齧合(hé)線(xiàn)形成(chéng)的泵工作(zuò)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(chù)于同一壓力腔中，軸向力可以自行平衡。兩端軸承采用外裝式，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(bìng)不接觸(chù)，而留有一微小間(jiān)隙，介質中(zhōng)的雜質并不能對螺杆齒(chǐ)面産生直接的磨(mó)損(除沖刷外)。 除一(yī)些小排量泵外(2W.W4.0以下)，一般在(zài)泵(bèng)體上(shàng)都帶有内流式安全閥，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(zhǒng)，一為水平(píng)進，水平出;二為水平(píng)進，垂直向上出;用(yòng)戶(hù)可根據(jù)自己需要選(xuǎn)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.
