   ●雙螺杆泵有(yǒu)密封式和不密封(fēng)式兩種類型，按介(jiè)質從(cóng)一端還是 從兩端進入齧合空間，雙螺杆又被分為雙吸式和單吸式兩種結(jié)構。雙螺杆泵是外齧合的螺杆泵，它利用相互齧合，互不接觸的兩根螺杆來抽送液體。雙螺杆泵(bèng)為一種雙吸式非密閉的雙螺杆泵。一端伸出泵外的主動螺杆由(yóu)原動(dòng)機驅動。主(zhǔ)動螺杆與從動螺杆具有(yǒu)不同旋向的螺紋。螺杆與泵體緊(jǐn)密(mì)貼合。從動螺杆是通過同步齒輪由主動螺杆帶動的。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(shuāng)螺(luó)杆泵作為一種容積式泵，泵内吸入(rù)室應與排出室嚴(yán)密(mì)地隔開(kāi)。因此，泵體與螺杆外圓表(biǎo)面及螺杆與(yǔ)螺杆間(jiān)隙應盡可能小些。同時螺杆與(yǔ)泵體、螺(luó)杆與螺杆間又相互形(xíng)成密封腔(qiāng)，保證密閉，否則(zé)就可能(néng)有液體從間隙中(zhōng)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.

   ●雙螺杆泵可分為内置軸承和(hé)外置(zhì)軸承兩種形式。在内置軸承的結構型式中軸承由輸送物進(jìn)行潤滑。外置軸承結構的(de)雙螺杆泵工作腔同軸承是分開的。由(yóu)于這種(zhǒng)泵的結構和螺杆間存在的側間隙，它可以輸送非潤滑性介(jiè)質。此外，調整同步齒(chǐ)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(rú)所有螺杆泵(bèng)一樣，外置軸承式雙螺杆泵(bèng)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(bù)置(zhì)，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 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(luó)杆泵系列産品分為單吸雙螺杆泵和雙吸雙(shuāng)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，廣泛适用于(yú)石油、化工、冶(yě)金、鋼鐵、電(diàn)力、船舶、制藥、食品、建材等(děng)各種行業，其适用介質之多、輸送範(fàn)圍之廣、應用工況之複雜是其它泵(bèng)類産(chǎn)品無法比(bǐ)拟的。這些特(tè)點也使得該系列泵具有潛在的使用發展前景。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.

   ●泵體内裝有兩根左、有施單頭(tóu)螺紋的螺杆(gǎn)，主動螺杆2由動力機驅動轉動時，靠同步齒輪1帶動從(cóng)動螺杆3轉動。兩根螺杆以及螺杆與泵體.之間存在着間隙，該(gāi)間隙(xì)靠齒輪和軸承保證。其間(jiān)隙(xì)大小，取(qǔ)決(jué)于(yú)液體粘度、工作(zuò)壓力等(děng)因素。由于每根螺杆兩端螺紋的旋向相反，螺杆轉動(dòng)時，由螺杆齧合線形(xíng)成的泵工(gōng)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.
