Investigating the centrifugal force acting at the root of the blades of a low-rotor-speed impeller in a high-pressure centrifugal fan

The high-pressure centrifugal fan is a commonly used high-pressure centrifugal fan in our daily life. This type of high-pressure centrifugal fan can be applied in various aspects of various industries. For example, ventilation in buildings and smoke treatment in kitchens require ventilation devices. Whether it is a centrifugal fan or a high-pressure centrifugal fan, rotating blades are required. During the rotation of the blades, centrifugal force is inevitable, but if the centrifugal force exceeds the allowable limit of the material, the blades will be damaged and fly out, which is extremely dangerous to production and life. To avoid this situation, we calculated and studied the centrifugal force of the path of the high-pressure centrifugal fan. 

1. When calculating the centrifugal force at the tip of the cutting tool, what needs to be analyzed is the centrifugal force of the blade. First, the centrifugal force at the tip of the tool needs to be determined based on the speed. The speed of the blade can be adjusted during the manufacturing process in China. 

2. The shear force of the high-pressure centrifugal fan is the result of dividing the centrifugal force by the root area of the blade. This is a fixed value that remains unchanged during the processing. Due to the material limitations of the blade itself, the allowable stress is restricted. To study this, the faster the blade rotates, the greater the centrifugal force acting on the root of the blade. 

3. If the centrifugal force at the root of the blade of the high-pressure centrifugal fan causes a shear stress that exceeds the allowable shear stress of the blade, the blade will be damaged. To avoid this danger, the speed is limited to below the maximum speed.
