德国KAYSEN凯森进口双螺杆泵概述

进口双螺杆泵是由主从动轴上相互啮合的螺旋套和泵体或衬套间形成一个容积恒定的密封腔室，介质随螺杆轴的转动分别被送到泵体中间，两者汇合在一起，最终送达泵的出口，从而实现泵输送的目的。

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。

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。

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。
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。

主要特点：
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。

Germany Kaysen imported twin screw pump overview

The twin-screw pump forms a sealed chamber with a constant volume between the spiral sleeve and the pump body or the bushing which are engaged with each other on the main driven shaft, and the medium is respectively sent to the middle of the pump body with the rotation of the screw shaft, and the two are merged together. Finally, it is delivered to the outlet of the pump to achieve the purpose of pump delivery.

The twin-screw pump is available in both sealed and unsealed versions. The two screws enter the meshing space from one end or from both ends. The twin-screw is divided into two types: double suction and single suction.

The twin-screw pump is an externally engaged screw pump that uses two screws that are in mesh with each other and that are not in contact with each other to pump liquid.

The twin screw pump is a double suction non-closed twin screw pump. An active screw that extends out of the pump at one end is driven by the prime mover. The active screw and the driven screw have different directions of rotation. The screw is in close contact with the pump body. The driven screw is driven by the drive screw through the synchronizing gear.

The twin-screw pump is a positive displacement pump, and the suction chamber inside the pump should be closely spaced from the discharge chamber. Therefore, the outer surface of the pump body and the screw and the gap between the screw and the screw should be as small as possible. At the same time, the screw and the pump body, the screw and the screw form a sealed cavity between each other to ensure the sealing, otherwise the liquid may flow back from the gap.

Twin screw pumps can be divided into two types: built-in bearings and external bearings. In the structural version of the built-in bearing, the bearing is lubricated by the conveyed material. The twin-screw pump working chamber of the external bearing structure is separate from the bearing. Due to the structure of the pump and the side gaps between the screws, it can transport non-lubricating media. In addition, adjusting the synchronizing gear causes the screw to not contact and transmits half of the output torque to the driven screw. Like all screw pumps, the externally mounted twin-screw pump also has self-priming capability, and most of the pump delivery elements are themselves in a double-suction symmetrical arrangement that eliminates axial forces and also has a large suction height.

The twin-screw pump series is divided into two categories: single-suction twin-screw pump and double-suction twin-screw pump. This series of products has special screw type lines and special structures matched with them. It is widely used in various industries such as petroleum, chemical, metallurgy, steel, electric power, shipbuilding, pharmaceutical, food, building materials, etc. The wide range and complexity of application conditions are unmatched by other pump products. These characteristics also make this series of pumps have potential development prospects.

main feature:

The pump adopts a double suction structure, and both ends of the screw are in the same pressure chamber, and the axial force can be balanced by itself. The bearings at both ends are externally mounted and lubricated with lubricating oil (fat) alone, so they are not affected by the conveying medium. The two screws are driven by a pair of synchronous gears, and the tooth faces of the screw are not in contact with each other, leaving a slight gap. The impurities in the medium cannot directly wear the tooth surface of the screw (except for flushing). Except for some small displacement pumps (below 2W.W4.0), there are generally internal flow safety valves on the pump body. When the discharge pressure exceeds the rated value, it has a certain protective effect. There are two kinds of inlet and outlet directions on the pump body, one is horizontal and horizontal, and the other is horizontal and vertical. The user can choose according to his own needs.
