Single Tube screw valve Eccentric Screw Rotor Dispensing Valve
Machine Introduction
Single-tube screw valves are precision volumetric metering and conveying devices that cater to a broad spectrum of high-precision quantitative conveying applications. The single-component screw pump boasts a spiral design structure, incorporating a self-sealing arrangement between the screw and stator. As the screw rotates inside the stator cavity, it fulfills a quantitative conveying function. This conveying process is gentle, as it avoids applying any shear force to the medium, thus preserving its properties. Furthermore, the pump can be reversed using the motor, enabling efficient suction and facilitating easy adhesive breaking. This feature offers an effective remedy to the challenges of dripping and pulling encountered during the dispensing process.
Working Principle
The volumetric metering and filling system of the single-tube screw valve operates on the infinite piston principle, characterized by a hermetic seal between the rotor and stator. As the rotor rotates within the stator core, it achieves precise quantitative delivery of colloids and fluids with a wide range of viscosities, from low to high.
The volumetric delivery metering pumps, which are central to each application, ensure pressure stability and linear pump characteristics. These pumps establish a predictable correlation between pump speed, time, and flow rate, allowing for consistent material metering through either time control or pump rotational speed.
Regardless of whether the fluids have low or high viscosity, are made of abrasion-resistant materials, or are highly filled and sensitive to structural changes, the dispensing accuracy remains unaffected by viscosity variations.
