Overview

twin-screw pump is a device that conveys fluid by rotating twin-screw. It uses two screws that cooperate with each other, one of which is a driving screw and the other is a driven screw. The fluid is sent from the suction end to the discharge end through the intermeshing screws. In the process of use, the twin-screw pump has the advantages of large flow, flexible and reliable, and strong self-priming ability. It is suitable for a variety of fluid transportation and applications.

working principle The working principle of the

twin-screw pump is to squeeze the liquid from the suction end to the discharge end through two intermeshing screws. Among them, the driving screw actively rotates, and the driven screw is pulled and rotated to form a sealed spiral cavity, and the fluid moves sequentially in the cavity. When the screw rotates once, the liquid is smoothly transported from the suction end to the discharge end. According to the number and shape of the screw, the twin screw pump can be divided into different types, such as ordinary twin screw pump, three screw pump, four screw pump and so on.

advantages and applications

twin-screw pump has many advantages, including:

1. High efficiency: twin-screw pump has the characteristics of high flow and high head, at a lower speed can transport a large number of liquids.

2. Flexible: Twin-screw pump is suitable for conveying a variety of fluids, including high viscosity, high temperature, high corrosion and other liquids.

3. self-priming ability: twin-screw pump has good self-priming ability, suitable for suction containing gas, foam, water and other liquids.

4. Convenient maintenance: The twin-screw pump has a simple structure and is easy to maintain and clean.

twin-screw pumps are widely used in petroleum, fine chemical, food, pharmaceutical, paper and other industries, such as conveying various liquid products, liquid processing raw materials, waste liquid treatment, wastewater treatment, sludge treatment, etc. At the same time, the twin-screw pump can also be used in conjunction with the frequency converter to achieve precise control of flow and head. Its wide applicability and superior performance have been recognized and widely used by users in many industries.

conclusion

twin-screw pump as an efficient, flexible, self-priming fluid conveying equipment, has been widely used in many industries. By understanding the working principle, advantages and application areas of the twin screw pump, consumers can better understand and use the device, thereby achieving more efficient fluid delivery and processing.
