    ●雙(shuāng)螺杆泵有(yǒu)密封(fēng)式和(hé)不(bú)密封式(shì)兩(liǎng)種類型(xíng)，按介(jiè)質從一端還是 從兩端(duān)進(jìn)入齧合空(kōng)間(jiān)，雙螺杆又被分(fèn)為雙吸(xī)式(shì)和單吸式兩(liǎng)種結構。雙螺杆(gǎn)泵是外齧(niè)合的(de)螺杆泵，它(tā)利用(yòng)相互(hù)齧合，互不(bú)接觸(chù)的兩(liǎng)根螺(luó)杆來抽送液體(tǐ)。雙螺杆泵(bèng)為一(yī)種雙吸(xī)式(shì)非密閉的雙(shuāng)螺(luó)杆泵。一端伸出(chū)泵外(wài)的主(zhǔ)動螺杆由原動機驅動。主(zhǔ)動螺杆與從動螺杆(gǎn)具有不同(tóng)旋向的螺紋。螺(luó)杆與(yǔ)泵體緊密(mì)貼合。從(cóng)動螺杆是通過同步齒(chǐ)輪由主(zhǔ)動螺杆(gǎn)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(gǎn)泵作(zuò)為一種容(róng)積式泵(bèng)，泵(bèng)内吸入室(shì)應與(yǔ)排出(chū)室嚴密(mì)地隔開(kāi)。因此，泵體(tǐ)與螺(luó)杆外(wài)圓表面及(jí)螺杆與螺杆間(jiān)隙應盡(jìn)可能小(xiǎo)些。同時(shí)螺杆與泵(bèng)體、螺杆與螺(luó)杆間又相(xiàng)互(hù)形(xíng)成密封腔，保證(zhèng)密閉，否則就可能有液體(tǐ)從間(jiān)隙中倒流(liú)回去(qù)。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(zhóu)承和外置軸(zhóu)承兩種(zhǒng)形式(shì)。在内置軸承的結(jié)構型式(shì)中軸(zhóu)承(chéng)由(yóu)輸(shū)送物進(jìn)行潤滑。外置軸承結構的(de)雙螺杆泵工作(zuò)腔同(tóng)軸承是分(fèn)開的(de)。由(yóu)于這種(zhǒng)泵的結構和螺(luó)杆間(jiān)存在的側間隙，它可(kě)以輸(shū)送非潤(rùn)滑性介(jiè)質。此外，調(diào)整同(tóng)步齒(chǐ)輪使得螺(luó)杆不接觸，同時(shí)将輸(shū)出扭(niǔ)矩的一半傳(chuán)給(gěi)從動(dòng)螺杆。正(zhèng)如所有螺杆泵一樣，外(wài)置軸(zhóu)承式雙螺(luó)杆泵也有(yǒu)自吸(xī)能(néng)力，而且多數(shù)泵輸送元(yuán)件(jiàn)本身都(dōu)是(shì)雙吸對(duì)稱布置，可消除(chú)軸向(xiàng)力，也(yě)有很(hěn)大的(de)吸(xī)高(gāo)。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.

    ●泵體内裝有兩(liǎng)根左(zuǒ)、有施(shī)單(dān)頭螺紋(wén)的螺杆，主動螺(luó)杆2由動力(lì)機(jī)驅(qū)動轉(zhuǎn)動時(shí)，靠同(tóng)步齒輪(lún)1帶(dài)動從(cóng)動螺(luó)杆3轉動。兩(liǎng)根螺杆以(yǐ)及螺(luó)杆與泵體(tǐ). 之間存在着間隙，該(gāi)間隙(xì)靠齒輪和(hé)軸承保證(zhèng)。其間(jiān)隙大(dà)小，取決于(yú)液體粘度、工作(zuò)壓力等因素。由(yóu)于每(měi)根(gēn)螺杆兩(liǎng)端螺(luó)紋的(de)旋向相反，螺杆(gǎn)轉動(dòng)時，由螺(luó)杆齧(niè)合(hé)線形成的(de)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.

   ●該(gāi)型泵采(cǎi)用雙(shuāng)吸式結構(gòu)，螺杆兩端處于(yú)同一壓(yā)力腔中(zhōng)，軸向(xiàng)力可以自(zì)行平衡。兩(liǎng)端軸(zhóu)承采(cǎi)用外裝式(shì)，單獨采用潤滑油(脂)潤(rùn)滑(huá)，因而(ér)不受(shòu)輸送(sòng)介質(zhì)的影響(xiǎng)。兩螺杆(gǎn)間用一對同步齒輪(lún)驅動，螺杆(gǎn)齒面間并(bìng)不(bú)接(jiē)觸，而留有一微(wēi)小間隙，介(jiè)質中(zhōng)的雜(zá)質并不能對螺杆(gǎn)齒面産(chǎn)生直(zhí)接的磨(mó)損(sǔn)(除沖(chòng)刷(shuā)外(wài))。 除一(yī)些小排量泵外(wài)(2w.w4.0以下(xià))，一般在泵(bèng)體上(shàng)都(dōu)帶有内(nèi)流式(shì)安(ān)全閥，當(dāng)排放壓力(lì)超過額定(dìng)值時，有一(yī)定的保護作用(yòng)。 泵(bèng)體上(shàng)的(de)進出(chū)口方向有兩種，一為(wéi)水平(píng)進，水(shuǐ)平出;二為水平(píng)進，垂(chuí)直向(xiàng)上出;用戶可根據自(zì)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.
