Working Principle

The G/QSJ series vertical circulating multi-curved mixer is a marvel of engineering, operating on a principle that is both innovative and efficient. Its impeller features a hyperbolic design, crafted through the elegant rotation of a hyperbolic bus around the impeller body's axis. This sophisticated impeller merges the art of fluid dynamics with precise mechanical motion. At the heart of its design is a hyperbolic equation, xy=b, elegantly rotated along the y-axis to create a uniquely curved surface. The central inlet of the impeller is meticulously engineered to streamline water flow, reducing turbulence and ensuring consistent liquid pressure across its surface—a key to achieving operational stability. The mixer boasts eight strategically positioned guide vanes on its involute double curved surface. Working in harmony with liquid weight pressure and the centrifugal force from impeller rotation, these vanes propel the liquid in a smooth tangential flow around the circumference. This action, enhanced by the reflective effect of the pool wall, establishes a dynamic top-down water circulation. It achieves cross-flow in both axial (y) and radial (x) directions, culminating in an unparalleled mixing efficiency.
The G/QSJ series vertical circulation multi-curved mixer stands out with its unique design, notably its strategic near-bottom pool installation. This thoughtful positioning is vital in preventing suspended matter from settling, thereby ensuring optimal mixing performance. It effectively eliminates dead zones and facilitates a high degree of water exchange, thanks to its larger specific surface area, ensuring every part of the pool remains vibrant and active.

Sizing Applications

The selection process for multi-curved mixers parallels that of other mixers, with the installation method being the only distinctive factor. Fundamental parameters, such as the type of pool, its volume, the depth of the liquid, the concentration of the medium, the temperature, and pH levels, are all vital components in making an informed selection.
The selection of curved mixers primarily depends on accurately determining the effective service area of each device. For rectangular pools, it is essential to maintain a length-to-width ratio of no more than two, enabling the pool to be divided into equal work units, which helps in determining the exact number of mixers required to achieve optimal efficiency.
For pools that exceed 5 meters in depth or those with concentrations that are higher than specified, it is imperative to consider enhancing either the power or the operational speed of the mixer. This enhancement ensures effective mixing, especially in scenarios involving large capacity and high concentration media.
Under standard operating conditions, a dry installation is highly recommended. However, in environments where noise or visual constraints are present, opting for a submersible installation is advisable. Our company is readily available to assist users in selecting the most suitable option for unique and special environments.
