●雙螺杆泵有密封式和(hé)不(bú)密封式兩種類型(xíng)，按介質從(cóng)一端還(hái)是 從兩(liǎng)端進入齧合(hé)空間，雙螺(luó)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(gǎn)泵，它(tā)利用相互齧合，互不接觸的兩根螺杆來抽送液體。雙螺杆泵為一種雙吸式非密閉的雙螺杆泵。一端(duān)伸出泵(bèng)外的(de)主動螺杆由原動機驅動。主(zhǔ)動螺杆(gǎn)與從(cóng)動螺杆具有(yǒu)不同旋向的螺(luó)紋(wén)。螺杆與(yǔ)泵體緊密(mì)貼合。從動螺杆是通過同步齒輪由主動(dòng)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(rù)室應與排出室嚴密地隔開。因此，泵體與螺杆外圓表面(miàn)及螺杆(gǎn)與螺杆間隙應盡可(kě)能小(xiǎo)些。同(tóng)時螺杆與泵體、螺杆與螺杆間又相互形成密封腔，保證密閉，否則(zé)就可能有液體從間隙中(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)外置軸承兩種形式。在内置軸承的結構(gòu)型式中軸承由輸送(sòng)物進行(háng)潤滑。外(wài)置軸承結構的雙螺杆泵(bèng)工作腔(qiāng)同軸承是分開的。由于這種泵的結構和螺杆間存在的(de)側間隙，它可以輸(shū)送非潤滑性介(jiè)質。此(cǐ)外，調整同步齒輪使得螺杆不接觸，同時将輸出扭矩的一半(bàn)傳給從動螺杆。正如(rú)所有螺杆泵一樣，外置軸承式雙螺杆泵也有(yǒu)自吸能力，而且多數泵輸送元(yuán)件(jiàn)本身都是雙吸對稱布置(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.
●雙螺杆泵(bèng)系列産品分為單吸雙螺杆泵和雙吸雙螺杆泵兩大類(lèi)。該系列(liè)産品具(jù)有特殊的螺杆(gǎn)型線和與(yǔ)之配套的特殊結構(gòu)，廣泛适(shì)用于石油、化工、冶(yě)金、鋼鐵、電力、船舶(bó)、制藥、食品、建材等各種行業，其适用(yòng)介質之多、輸送範(fàn)圍之(zhī)廣、應用工(gōng)況之複雜是其它泵類産品無(wú)法比拟的。這些特點也使(shǐ)得該系列泵具有(yǒu)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)的螺杆，主動螺杆2由動力機驅(qū)動轉動時，靠同步齒輪1帶(dài)動從(cóng)動螺杆3轉(zhuǎn)動。兩根螺杆以及螺(luó)杆與泵體.之間(jiān)存在着間隙(xì)，該(gāi)間隙靠齒輪和(hé)軸承保證。其間隙大(dà)小，取決于液體粘度、工作壓力等因素。由于每根螺杆兩端螺紋的(de)旋(xuán)向相(xiàng)反，螺(luó)杆轉動時，由螺杆齧合線形(xíng)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.
