The overall performance of the fan blade and the structure analysis of the annular multi-stage blade

The new fan blade can make the mold processing easier, reduce the manufacturing cost, change from the original multi-slider combination demoulding to the front and back direct demoulding, the multi-slider combination has poor processing accuracy, difficult tolerance matching, and high manufacturing difficulty. New structure There is no multi-slider combination for the fan blade, the mold is composed of two parts, the mold is more stable, and the cost is reduced. The manufacturing difficulty is lowered, but the product precision is improved.

How does the shape of the fan blade affect the air volume of the fan?

There are motor power, fan blade angle, fan speed, etc. in electromechanical equipment. If it is a mine fan, the downhole factors include changes in mine resistance, whether the air path has been adjusted, increase the resistance, and the fan will return to reduce the total air volume. But the general impact is not great.

Let's analyze the reasons why the speed of the DC cooling fan slows down

With the continuous improvement of people’s living standards, the application of DC cooling fan blades has become more and more extensive, have you noticed that sometimes it becomes slower and slower when in use? Don’t worry, the following article will simply share DC for everyone The reason why the speed of the cooling fan blades slows down.

Why do you want to reduce the noise of the fan blades?

The principle of energy-saving and noise-reducing fan The fan can be separated into two types: the core type and the axial type according to the principle. When the centrifugal fan rotates, the centrifugal force generated will throw the air between the blades to the outer edge of the impeller. Therefore, at the outlet of the outer edge of the fan impeller Pressure is formed at the place where the airflow changes in the direction of movement. At the same time, a large vortex is generated between the blades. Also, due to the improper matching of the shape of the wind cover and the fan, the airflow forms a local vortex in the outer cover, so the efficiency is only 20-30 %, the general wind consumption is about the motor capacity.

The function of axial fan blades and the calculation method of angular spacing

The improved axial flow fan blade can effectively overcome the shortcomings of the prior art, is convenient for stacking, prevents collision, and achieves the purpose of convenient packaging, transportation and storage. The fan blade includes a hub, a blade and a middle plate located in the hub.
