Multistage centrifugal fan is a type of fan commonly used in industrial and construction fields, and its structural composition usually includes the following main parts:
Shell: The shell of a multi-stage centrifugal fan is the outermost structural component. It is usually made of steel plate or aluminum alloy to protect the various components inside the fan, and connects the air or gas Imported from the outside.
Impeller: The impeller is a key part of a multistage centrifugal fan. It consists of multiple blades and is usually made of aluminum alloy or steel. When the fan is running, the impeller spins and draws in air or gas, which is then accelerated by centrifugal force and sent to the next stage or final discharge.
Vane guide: The vane guide is a device used to adjust the flow and pressure of a multi-stage centrifugal fan. It is usually installed at the inlet of each impeller and consists of multiple rotatable blades. By adjusting the angle of the blades, the vane guide can change the flow direction and speed of the inlet fluid, thereby affecting the output of the fan.
Drive device: The drive device usually consists of a motor and a transmission mechanism to provide power to drive the impeller to rotate. The motor usually adopts a three-phase asynchronous motor, and the power of the motor is transmitted to the impeller through a transmission mechanism such as a belt or a gear, thereby driving the impeller to rotate.
Support frame: The support frame is used to support the various components of the multi-stage centrifugal fan, and is usually made of steel or aluminum alloy. Its structure is stable and can ensure the normal operation of the fan.
Control system: The control system of multi-stage centrifugal fan is usually composed of frequency converter, PLC, sensor and so on. The frequency converter can adjust the speed of the motor, the PLC can control the operation of the entire fan, and the sensor can monitor the status of the fan.
Each component plays an important role, and through mutual cooperation, the normal operation of the fan is realized. Our company can also provide customized services according to your needs for parts.
