Hengtong series HT5.1/D**

The circumference of the wheel hub is composed of four sets of hexagonal steel sliding cavities. Each group of sliding cavities has two sliding holes embedded with sliding blocks of the same shape. The front of both sliders are concave in shape. The front end of the leaf stem is equipped with a protruding lock block, which exactly matches the concave shape of the two sliding blocks. Two sliders are machined with a through hole in the center of the front end of the blade handle, and the fastening bolt runs through it to lock and fasten the three components together.

Superior technology • wheels

The hub is surrounded by four sets of hexagonal steel slip cavities.

Each set of sliding cavities has two sliding holes embedded with sliders of the same shape. The front of both sliders has a concave shape.

The front end of the petiole is provided with a convex lock block, which just fits the concave shape of the two sliders.

The two sliders are machined with a through-hole in the center of the front end of the petiole through which the fastening bolts lock and fasten the above three parts together.

The outer surface of the slider is covered with a rubber vibration isolation sleeve, in case of external force hitting the blade, the vibration energy is transmitted to the slider through the petiole, the rubber isolation sleeve will absorb most of the vibration energy, prolong the collision time, thereby slowing down the impact of the blade, petiole and hub.

Superior technology • blades

Made of magnesium and aluminum, 1.5 mm thick. Stamping process forming.

Hengzhengtong's self-made blades integrate the research results of modern aerodynamics.

Due to the huge fan size, the linear speed of the blades in all directions along the radius gradually increases, and the speed of the outermost edge of the blades exceeds 19 meters per second, while the speed of the root is only about 3 meters per second. The huge speed difference inevitably requires the blade to have a corresponding blade shape in the low-speed area and the high-speed area to maximize the air supply effect of the blade.

First of all, the width of Hengzhengtong blades in the low-speed area of the root is about twice that of the high-speed area of the tip, and the low-speed area relies on wide blades to drive more airflow, while the relatively narrow blades in the high-speed area convey airflow through the speed. Such a blade design makes the air supply of the entire blade more balanced.

Secondly, the angle of attack (inclination angle of the blade) of the blade has different requirements in the high and low speed areas.

In low-speed areas, it is hoped that the number of attack angles will be large, and the static pressure of the fan will be increased to expand the coverage area.

In the high-speed area, it is hoped that the number of angles of attack is small, increase the dynamic pressure of the fan, and increase the air volume.

Hengzhengtong blades meet the above aerodynamic requirements, and are twisted blades along the radius direction, under the same circumstances, not only increase the coverage area of the fan, but also take into account the fan air volume.

Finally, Hengzhengtong sets the fan blades to 3-5 degrees upturned at the tip of the blade, corresponding to the horizontally installed blades, and the upturned blades expand the direct coverage area.
