Comparison of two bracket cooling fans.clip fan Production

　　The bracket cooling fan is a very common cooling fan in industrial production. The bracket cooling fan has its own role in all aspects of industrial production, which can be said to be very important. There are many different types of bracket cooling fans, so let's find two common bracket cooling fans for comparison.

　　There are many model codes for cooling fans, and the numbering rules of different brands of fans are different, making it impossible to see its size and voltage at first glance. Today, I will explain the number of a common cooling fan and their differences.

　　FZY series power frequency axial flow fans should be the most commonly used fans in the market. There are many manufacturers producing this series of fans, and the prices vary greatly from low to high. The number 200 indicates the diameter of the fan blades in mm. It can be seen that this fan is relatively large. If the outer frame is included, the outer diameter of 200FZY-D is about 250mm, and the outer diameter of 200FZY-S is 225mm. In terms of parameters, because there are various specifications, there is nothing to compare. In appearance, 200FZY-D is round and 200FYZ-S is square. Each letter of FZY represents: F-fan, Z-axial flow, Y cylinder type. It can be seen that this is an authentic domestic fan, which is named after Pinyin. Recently, people often say that they need fans from Taiwan Sanxie, but the model reported is FZY. I really don't know how these people are fooled.

　　The biggest difference between these two fans is that on D and S, there are many fans who do not know the difference, and there are various explanations. For example, some people say that DS is a metal leaf and a plastic leaf. . . . The correct interpretation of D and S should be that D stands for single flange and S stands for double flange. Generally speaking, the D model has screw holes on one side to fix the fan, while the S model has screw holes on both sides.

　　When an axial fan works, the blades push the air to flow in the same direction as the shaft, so it is called an axial fan. Axial fans are divided into large axial fans, medium axial fans, and small axial fans. Choose the appropriate axial fan according to the required use. Generally speaking, large axial fans are mainly suitable for exhaust air in places such as dust and gravel fields; medium axial fans are mainly suitable for indoor ventilation and heat removal, such as granaries, etc.; small axial fans are mainly suitable for Ventilation and heat dissipation of mechanical equipment, such as electrical cabinets, etc.
