There are main differences with axis flow in multiple aspects:
The direction of exhaust air: The exhaust direction of the axis fans is directly discharged along the direction of the shaft. The air inlet and exhaust port of the fan are on a shaft parallel line.The winding direction of the centrifugal fan is vertically in the direction of the air inlet, which can achieve 360 ??-degree designated directional exhaust.
Installation difficulty: The installation of the axis flowers is relatively simple, and is generally installed directly on the wall or connecting the duct.In contrast, the installation of centrifugal fans is relatively complicated. When installation, the bearing seat and the base must be closely connected. The cutting surface of the base should be properly protected and should not be corroded or operated.When the fan is looking for, the radial positioning shift should not exceed 0.05 mm.
Air volume and wind pressure: The air volume of the axis flowers is relatively small, and there is basically no wind pressure.The air volume pressure of the centrifugal fan is relatively large, which is especially suitable for pipeline pumping or air supply. It is usually used in pipeline to transport air. It can be used without corrosion, flammable and explosive gas places, which can achieve good ventilation effects.
The appearance of the appearance: The appearance of the axis fans is basically a cylindrical shape, and the appearance of the centrifugal fan is snail -shaped.
Electric connection method: The motor connection of the bearing fan is generally in the body of the fan.The motor of the centrifugal fan is connected by the axis, which is generally outside the fan pumping.
In addition, there are some characteristics of centrifugal fans:
Convenient maintenance: Some models of the centrifugal fan can be equipped with cleaning doors. There is no need to disassemble the machine during maintenance, saving time.Moreover, the impeller design of the centrifugal fan is reasonable, without friction during runtime, the noise is very low and it is not easy to stick to dust, which is very convenient to maintain.
Strong corrosion resistance: The surface of the centrifugal fans is spraying, strong antioxidant, and is not easy to be corroded.The case and the impeller use the high -quality steel plate, making the centrifugal fan very strong and durable.
In general, there are obvious differences in centrifugal fan and shaft fan in terms of air discharge direction, difficulty in installing, air volume and wind pressure, appearance shape, and motor connection.Features.The choice of fan depends on the specific application scenarios and needs.
