ALLWEILER screw pump And Gear pump It is a common type of centrifugal pump. Although both are used to transport liquids or gases, they have different advantages in design and working principle.

first, ALL WEILER Screw pump The design of is simpler and consists of a main shaft and a screw. The main working principle of the screw pump is to use the rotation of the screw to form a sealing chamber, form a closed space between the screw and the pump housing, and then drive the liquid or gas from the suction end of the pump to the push end through the rotation of the screw. In contrast, a gear pump is composed of a pair of gears that mesh with each other, and the liquid or gas is driven by the rotating movement of the gears. Since the screw pump has only one main shaft and one screw, its structure is simpler, IMO agent The repair and maintenance are more convenient.

Secondly, ALLWEILER screw pump produces less pulsation during transportation. Screw pump conveys liquid or gas through continuous rotary movement, so the flow is relatively stable, the flow continuity is better, and the pulsation is smaller, which can reduce the vibration and impact generated by the fluid. This is very important for applications that require stable flow, such as transporting high viscosity liquids or gases, and transporting liquids or gases that are easily consumed.

In addition, ALLWEILER screw pump has strong self-priming capacity. The rotary motion of the screw pump can drive the liquid or gas to form a relatively low pressure at the suction end of the pump, thus generating a strong self-priming capacity, which can achieve self-priming function within a certain range. This is very advantageous for situations where liquid level changes greatly or long-distance suction is required, IMO screw pump It can greatly reduce the layout and maintenance cost of the pump station.

In addition, ALLWEILER screw pump can transport medium with higher temperature and viscosity. Because the structure of screw pump is relatively simple and there are fewer vulnerable parts, it can withstand higher temperature and viscosity media and is suitable for some special working conditions. At the same time, because of the special design of the screw pump, it can adapt to different liquids or gases, ALLWEILER Such as media with solid particles, high viscosity grease, etc.

Finally, ALLWEILER screw pump has better energy-saving effect. Due to the design principle of screw pump, the energy loss of liquid or gas is reduced and the pump efficiency is improved. In contrast, gear pump is prone to leakage and extrusion loss due to the meshing process of gears, and the energy loss is large. ALLWEILER screw pump

In conclusion, compared with gear pump, ALLWEILER screw pump has the advantages of simple design, small pulsation, strong self-priming capacity, wide adaptability and good energy-saving effect. These characteristics make the screw pump more widely used in some special working conditions, especially in the transportation of high viscosity liquids, high self-priming capacity requirements, high temperature requirements, and other occasions, the screw pump shows more excellent performance.
