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.
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.
