 一(yī)、雙螺杆泵(bèng)的特(tè)點
   雙螺(luó)杆泵可以無(wú)攪動無脈(mò)動平平穩地輸送各(gè)種介質，由于泵體結構保(bǎo)證泵的工作元件内始終(zhōng)存有泵送液體作為密封液體，所有的泵有很強(qiáng)的自(zì)吸能力，且能汽液混輸(shū)。
   雙螺杆泵的特殊設計保證了(le)泵有(yǒu)高的吸入性能(néng)即很小的NPSHr 值。
   雙螺杆泵采用獨立潤滑的外置軸承允許輸送各種非潤滑性(xìng)介質。
   雙螺(luó)杆泵采用同步(bù)齒輪傳動轉動零件互不接觸即使短時間幹轉也沒有危險( 1~2min)。
   卧式(shì)立式帶加熱套等(děng)各種結構型式齊全可以輸送各(gè)種清潔的(de)不含固體顆粒的低粘度或高粘度介質先用正确(què)的材質甚至可以輸送許多腐蝕性介質(zhì)。

   ●雙螺杆泵有密封式和(hé)不密(mì)封式兩種類型，按介質從一端還是(shì) 從兩端進入齧(niè)合空(kōng)間，雙螺杆又被分為雙吸式和(hé)單吸式兩種結構。雙螺(luó)杆泵是外齧合的螺杆泵，它利用相(xiàng)互齧合，互不接觸的(de)兩根螺杆來(lái)抽送液體。雙螺杆泵(bèng)為一種雙(shuāng)吸式非密(mì)閉的雙螺杆(gǎn)泵(bèng)。一端伸出泵外(wài)的主動螺杆由(yóu)原動(dòng)機驅動。主動螺杆與從動螺杆(gǎn)具有(yǒu)不同旋向的螺紋(wén)。螺杆與泵體緊密(mì)貼合。從動螺杆是通(tōng)過(guò)同步齒輪由(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(róng)積式泵，泵内吸入室應與(yǔ)排出室嚴密地隔開。因此，泵體與螺(luó)杆外圓表面及螺杆與螺杆間隙應盡可能小些。同時螺杆與泵體、螺杆與螺杆間又相互形(xíng)成密封腔，保證密閉，否則(zé)就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 e 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(gǎn)泵可分為内置軸承和外置軸承兩種形式。在内置軸承的結構型式中軸承由輸送物進行潤滑。外(wài)置軸承結構的雙螺杆泵工作腔同軸承是分開的。由(yóu)于(yú)這種(zhǒng)泵的結構和螺杆間存在的(de)側間隙，它可以輸送非潤滑性介質。此外，調整同(tóng)步齒輪使得螺杆不接觸，同時将輸出扭矩的一半傳給從動螺杆。正如所有(yǒu)螺杆泵一樣，外置軸承式(shì)雙螺杆泵也有自吸能力，而且多數泵輸送元件本(běn)身都是雙吸對稱布置，可(kě)消除軸向力，也有很大的(de)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 e 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單吸雙螺杆泵和雙(shuāng)吸雙螺杆泵兩大類。該系列(liè)産品具有特殊的螺杆型線和與之配套的特殊結構(gòu)，廣泛适用于石油、化工(gōng)、冶(yě)金、鋼鐵、電力、船舶、制藥、食品、建材等(děng)各種行業，其适用(yòng)介質之多、輸(shū)送範圍之廣、應用工(gōng)況之複雜(zá)是其它泵類産品無法比拟的。這些特點也使(shǐ)得該(gāi)系列泵具(jù)有潛在的使用發展(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.

   ●泵體内裝有兩根左、有施單頭螺紋(wén)的螺(luó)杆，主動(dòng)螺杆2由(yóu)動力機驅(qū)動轉動時，靠同步齒輪1帶動從動螺杆3轉動。兩根螺杆以及螺杆與泵體(tǐ).之間存在着間隙，該(gāi)間隙靠齒(chǐ)輪和軸承保證。其間隙大小，取(qǔ)決于(yú)液體粘度、工作(zuò)壓力等因素。由于每根螺(luó)杆兩端螺紋的旋向相反，螺杆轉動(dòng)時，由螺杆齧合線形成的泵工作腔(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.
