Application scope
The QSJ and GSJ series of hyperbolic surface agitators are the flagship products of our company. It is widely used in industries such as environmental protection, chemical engineering, energy, and light industry where solid-liquid-gas stirring and mixing of liquids are required. It is particularly suitable for use in coagulation tanks, regulating tanks, anaerobic tanks, nitrification and denitrification tanks in the sewage treatment process.
Structural Introduction
The hyperbolic surface agitator is composed of transmission components, impellers, bases, hoisting systems and electrical control systems. See the picture
Work characteristics
This is a stirring device capable of creating a large volumetric flow rate and can achieve large-area circulation and gentle water flow with relatively small power. The unique impeller structure design perfectly combines fluid characteristics with mechanical motion to the greatest extent. The surface of the hyperbolic impeller is a curved surface body formed by rotating the curve along the Y-axis with the equation xy=b. To accommodate the water flow, the design allows water to enter from the center of the impeller. This not only reduces the turbulence of the incoming water but also ensures that the pressure of the liquid on the impeller surface is uniform, thereby maintaining the balance of the entire machine during operation. Eight guide vanes are evenly distributed on the gradually opening double arc surface. The potential energy obtained by supplementing the water inflow with the self-weight pressure of the liquid and the kinetic energy generated by the centrifugal force when the impeller rotates form the kinetic energy. Under the condition of gravitational acceleration, the liquid moves tangentially along the circumference of the impeller. Under the reflection effect of the pool wall, a circulating water flow from bottom to top is formed, so the intersection in the axial (y) and radial (X) directions can be achieved Water flow. It is precisely because of the structural characteristics of the hyperbolic surface mixer impeller and its installation feature close to the bottom of the pool that it can achieve an ideal stirring effect during operation and effectively eliminate stirring dead corners.

Application selection
The selection of QSJ and GSJ is exactly the same; the only difference between them is the installation method. Just like the selection of all agitators, the selection of hyperbolic surface agitators is related to the on-site pool shape, volume, liquid concentration, medium temperature and PH, etc.
The selection of hyperbolic surface agitators is determined based on the effective service area of each hyperbolic surface agitator. According to the principle that the lengto-width ratio of the pool does not exceed twice, the rectangular pool is divided into equal working units to determine the number of agitators.
In addition, for water depths exceeding 8 meters or liquid concentrations exceeding the specified limits, when selecting the type, it is necessary to consider increasing the power or raising the working speed of the mixer to ensure the mixing effect in large-volume and high-concentration liquids. Under normal working conditions, the QSJ series can be selected. In harsh environments with high temperatures, high corrosion and abrasiveness, the GSJ series can be chosen. Our company can assist users in selection under special circumstances.
Installation method of 1GSJ
It is positioned by a bridge frame (full bridge or half bridge), powered by a thousand-type motor reducer, and the impeller has an automatic deviation correction function. The operation is relatively stable and maintenance is convenient.

2.QSJ installation method
Figure 1 shows the mixer being directly lifted into the designated position by a long-arm truck crane
Figure 2 shows the manual hoisting through the walkway bridge set by the pool.
Both of the above two methods involve direct hoisting and positioning by the self-weight of the equipment
