The twin-screw pump is a very common fluid delivery device. Compared with other pumps, twin-screw pumps have the characteristics of small size, wide flow range, good mixing performance, and can transport high-viscosity media.
The working principle of the twin-screw pump is very simple. It consists of two co-rotating screws, one as the main screw and the other as the slave screw. When the twin-screw pump works, the main screw and the slave screw mesh with each other to form a reciprocating thread groove, which sucks the medium from the suction end of the pump, and then pushes it to the outlet of the pump through the rotation of the screw, thereby completing the liquid transportation process.
The twin-screw pump can transport various media when working. The leakage between its transport volume and the mechanical seal is very small. The performance of the pump is very stable. It is widely used in chemical industry, metallurgy, petroleum, medicine, food and other industries. It is especially suitable for media that are difficult to transport, such as those with high viscosity, easy to agglomerate, easy to crystallize, and easy to volatilize.
In short, the twin-screw pump is a very excellent fluid conveying equipment. It has a simple working principle, reliable performance, easy to use, and can be used under various working conditions.
