●双螺杆泵有密封式和不密封式两种类型，按介质从一端还是从两端进入啮合空间，双螺杆又被分为双吸式和单吸式两种结构。双螺杆泵是外啮合的螺杆泵，它利用相互啮合，互不接触的两根螺杆来抽送液体。双螺杆泵为一种双吸式非密闭的双螺杆泵。一端伸出泵外的主动螺杆由原动机驱动。主动螺杆与从动螺杆具有不同旋向的螺纹。螺杆与泵体紧密贴合。从动螺杆是通过同步齿轮由主动螺杆带动的。doublescrew pump has sealed and not enclosed two types, according to themedium from the side or from both ends into space meshing, doublescrew was divided into double suction type and structure of singlesuction type two kinds.screw pump, twin screw pump is the externalgear utilizing the mesh each other, mutual contact of two screw topumping li screw pump is a kind of double suction notairtight double screw pump.active outside the side out of the pumpscrew driven by a prime mover.driving screw and driven screw threadwith different handedness.screw pump body and tightly.driven screwis driven by synchronous gear by the active screw.
●双螺杆泵作为一种容积式泵，泵内吸入室应与排出室严密地隔开。因此，泵体与螺杆外圆表面及螺杆与螺杆间隙应尽可能小些。同时螺杆与泵体、螺杆与螺杆间又相互形成密封腔，保证密闭，否则就可能有液体从间隙中倒流回去。doublescrew pump as a positive displacement pump, the pump suctionchamber should be closely separated and discharge chamberinside.therefore, the pump body and screw cylindrical surface andscrew and screw clearance should be as small as possible.screw pumpbody and at the same time, each other between the screw and screwand form a sealed chamber, ensure airtight, otherwise there may beliquid backflow from the gap.
●双螺杆泵可分为内置轴承和外置轴承两种形式。在内置轴承的结构型式中轴承由输送物进行润滑。外置轴承结构的双螺杆泵工作腔同轴承是分开的。由于这种泵的结构和螺杆间存在的侧间隙，它可以输送非润滑性介质。此外，调整同步齿轮使得螺杆不接触，同时将输出扭矩的一半传给从动螺杆。正如所有螺杆泵一样，外置轴承式双螺杆泵也有自吸能力，而且多数泵输送元件本身都是双吸对称布置，可消除轴向力，也有很大的吸高。doublescrew pump can be divided into internal bearing and the outerbearing two forms.in the built-in bearing structure bearinglubrication by conveying material.working with external bearingstructure of the double screw pump bearings are separated.owing tothe pump structure and side clearance between screw, it cantransport non-lubricative medium.in addition, the adjustment of thesynchronous gear makes the screw does not contact, at the same timethe output torque of the half to driven screw.like all of the screwpump, external bearing type twin-screw pump, and most are doublesuction pump element itself symmetric arrangement, can eliminatethe axial force, also has a lot of high absorption.
●双螺杆泵系列产品分为单吸双螺杆泵和双吸双螺杆泵两大类。该系列产品具有特殊的螺杆型线和与之配套的特殊结构，广泛适用于石油、化工、冶金、钢铁、电力、船舶、制药、食品、建材等各种行业，其适用介质之多、输送范围之广、应用工况之复杂是其它泵类产品无法比拟的。这些特点也使得该系列泵具有潜在的使用发展前景。doublescrew pump series products are divided into single suction of twokinds of double screw pump and double suction double screwpump.this series of products have special screw lines and form acomplete set with the special structure, widely used in petroleum,chemical industry, metallurgy, steel, electricity, shipbuilding,pharmaceutical, food, building materials and other industries, byas much as its applicable medium, transmission range wide,application condition of the complex is unmatched by other pumpproduct.these features also makes the use of this series of pumpswith potential development prospects.
●泵体内装有两根左、有施单头螺纹的螺杆，主动螺杆2由动力机驱动转动时，靠同步齿轮1带动从动螺杆3转动。两根螺杆以及螺杆与泵体.之间存在着间隙，该间隙靠齿轮和轴承保证。其间隙大小，取决于液体粘度、工作压力等因素。由于每根螺杆两端螺纹的旋向相反，螺杆转动时，由螺杆啮合线形成的泵工作腔。e two left in the pump body, a single thread screw, active screwdriven by engine 2 turns, driven by synchronous gear 1 driven screw3 rotation.two screw and screw and pump body. there is a gapbetween the gap by gear and bearing.the gap size, depends on theliquid viscosity, pressure and other factors.because each threadrotate to the opposite on both ends of the screw, the screwrotates, formed by the screw meshing line pump workingchamber.
●该型泵采用双吸式结构，螺杆两端处于同一压力腔中，轴向力可以自行平衡。两端轴承采用外装式，单独采用润滑油(脂)润滑，因而不受输送介质的影响。两螺杆间用一对同步齿轮驱动，螺杆齿面间并不接触，而留有一微小间隙，介质中的杂质并不能对螺杆齿面产生直接的磨损(除冲刷外)。除一些小排量泵外(2w.w4.0以下)，一般在泵体上都带有内流式安全阀，当排放压力超过额定值时，有一定的保护作用。泵体上的进出口方向有两种，一为水平进，水平出;二为水平进，垂直向上出;用户可根据自己需要选择。this type pumpadopts double suction type structure, at the same pressure in thecavity on both ends of the screw, the axial force can balanceitself.both ends of bearing mounted outside using, lubricated bylubricating oil (grease) separately, and therefore not affected bythe medium.with a pair of synchronous gears drive between the twoscrew, the screw does not contact between tooth surfaces, and leavea small gap, the impurities in medium can not be directly on thescrew tooth surface wear (except wash).except a few smalldisplacement pump (below 2 w. w4.0), generally contain flow reliefvalve on the pump body, when the discharge pressure exceeds rating,has certain protective effect.there are two kinds of the directionof the import and export on the pump body, one for level,level;secondly, level, vertical;user can choose according to theirown needs.
