    ●雙(shuang)螺杆泵有密封(fēng)式和不密封式(shi)兩種類型，按介(jie)質從一端還是(shi) 從兩端進入齧(niè)合空間，雙螺杆(gǎn)又被分為雙吸(xī)式⭐和單吸式兩(liǎng)種結構。雙螺杆(gan)泵是外齧合的(de)螺杆泵，它利用(yong)相互📱齧合，互不(bu)接觸的兩根螺(luo)杆來抽送液體(ti)。雙螺杆泵為一(yi)種雙吸式非密(mi)閉的雙螺杆泵(bèng)。一端伸出泵外(wai)的主動螺杆由(yóu)原動機驅動。主(zhǔ)動螺杆與從動(dong)螺杆具有不同(tong)旋向的螺紋。螺(luo)杆與泵體緊密(mi)貼合。從動螺杆(gan)是通過💃同步齒(chi)輪由主動螺杆(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)泵作為一種容(róng)積式泵，泵内吸(xi)入室應與排🔴出(chū)室嚴✂️密💘地隔開(kai)。因此，泵體與螺(luó)杆外圓表面及(ji)螺杆與螺杆🛀🏻間(jian)隙應盡可能小(xiǎo)些。同時螺杆與(yǔ)泵體、螺🧑🏽‍🤝‍🧑🏻杆與螺(luó)杆間又相互形(xíng)成密封腔，保證(zheng)密閉，否則就可(ke)能有液體從間(jian)隙中倒流回去(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)為内置軸承和(hé)外置軸承兩種(zhong)形式。在内置軸(zhóu)承❌的結構型式(shì)中軸承由輸送(song)物進行潤滑。外(wai)✨置軸承結🧑🏽‍🤝‍🧑🏻構的(de)🔞雙螺杆泵工作(zuo)腔同軸承是分(fèn)開的。由于這種(zhong)⛹🏻‍♀️泵的結構和螺(luo)杆間存在的側(ce)間隙，它可以輸(shu)送非潤滑性介(jie)質。此外，調整同(tóng)步齒輪使得螺(luó)杆不接觸，同時(shí)将輸出扭矩的(de)一半傳給從動(dong)螺杆。正如所有(yǒu)螺杆泵一樣，外(wai)☎️置軸承式雙螺(luo)杆泵也有自吸(xī)能力，而且多數(shu)🏃‍♂️泵輸送元件本(běn)身都是雙吸🐆對(duì)稱布置，可消除(chú)軸向力，也有很(hěn)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.
