Drive Arrangement A
Structural Features: Drive Arrangement A involves a drive assembly consisting of a main shaft, bearing housing, rolling bearings, and a pulley. In this configuration, the motor transmits power to the main shaft via a pulley and belt, driving the impeller to rotate.
Application Scope: This drive method is suitable for fans with moderate power requirements, such as the 4-72 series. It is commonly used for ventilation in general factories and large buildings.
Drive Arrangement B
Structural Features: Drive Arrangement B utilizes a belt drive but differs from Arrangement A in that it is typically used for higher-power fans. In this configuration, the motor is located outside the fan housing and transmits power to the impeller via a longer drive shaft.
Application Scope: Drive Arrangement B is suitable for fans with higher power requirements, such as the 4-72 series. It is used in settings requiring large air volumes, such as industrial plants and power stations.
Drive Arrangement C
Structural Features: Drive Arrangement C, also known as a direct coupling drive, connects the motor and impeller directly via a coupling. This method offers higher transmission efficiency and stability by minimizing energy loss during power transmission.
Application Scope: Drive Arrangement C is primarily used for fans requiring high power and efficiency, such as the 4-72 series. It is widely applied in industrial environments that require continuous, long-term operation.
Drive Arrangement D
Structural Features: Drive Arrangement D is a multi-stage transmission method typically used in applications requiring extremely high pressure and air volume. In this configuration, the motor distributes power to multiple impellers via a multi-stage transmission system to achieve high-pressure output.
Application Scope: Drive Arrangement D is suitable for large-scale fan systems, such as the 4-72 series. It is frequently employed in large industrial facilities and demanding engineering projects.
