●性能范围:Range of performance:

    1、最高工作压力4.0MPa  1, the maximum working pressure of 4.0 MPa

    2、流量范围 11000m3/h 2, 1 ~ 1000 m3 / h flow range

    3、温度范围-20120  3-20 ~ 120 , temperature range

    4、介质粘度 13000mm2/s,降低转速可达到106mm2/s 介质粘度对双螺杆泵性能影响较大,泵的名义排量是指在特定粘度条件下的排量,为保证泵能在较高效率下工作,在试验不充分时,建议按下列粘度条件选择转速:介质粘度cSt转速r/min  <4001500  400 12001000  12003600750

    4, 1 ~ 3000 was/s, medium viscosity reducing speed can reach 106 was/s medium viscosity influence the performance of double screw pump, pump displacement refers to the specific viscosity of conditions in the name of the displacement, in order to ensure the pump can work in high efficiency, when the test is not sufficient, suggestion choice speed on the viscosity of the following terms and conditions: medium viscosity cSt speed r/min < 4001500 400 ~ 12001000, 1200 ~ 400.

    ●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。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.

 

    ●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。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.

    ●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。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.

    ●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。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。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.

 

 

   ●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()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 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.

   ●双螺杆泵如何进行日常维护与保养:daily maintenance and maintenance:

    1、每日的维护和保养1, daily maintenance and maintenance

    1.1在螺杆泵停泵时检查齿轮箱(04)内的油位。若有必要,拆下注油螺塞(131),加油至油标(106)的中心处为止。1.2听听是否有异常噪声与震动。1.3在泵运转时检查泵是否有泄漏。1.1 in the screw pump when the pump is going to check the oil level in the gear box (04).If necessary, disassembling bet on oil plug (131), go to the center of the oil standard (106).1.2 listen to whether there are abnormal noise and vibration.1.3 check for leaks pump when the pump is running.

    注意:对于机械密封,在大多数情况下,由于汽化导致从密封泄液孔处观察不到泄漏,但有时少量而又稳定的泄漏是允许的。Note: for mechanical seal, in most cases, due to evaporation from seal leakage of fluid leaking hole in observation, but sometimes a small amount and stable leakage is allowed.

    2、每周检查与保养2, weekly inspection and maintenance
