The blower is a multifunctional and efficient equipment widely used in industrial and agricultural fields. It accelerates the air through a high-speed rotating impeller and reduces the air temperature by changing the flow direction and deceleration, while increasing the condensation effect of air humidity to achieve cooling and drying effects.
The structure of a blower includes an air inlet, impeller, diffuser, housing, motor, and other parts.
Among them, the air inlet is the inlet of the centrifugal fan, the impeller is a component of the centrifugal fan, the diffuser and housing are auxiliary components of the impeller, and the motor is the power source of the blower.
The impeller is a component of a blower, consisting of multiple blades. The shape and number of blades can affect the performance of the blower.
During operation, the motor drives the impeller to rotate at high speed, and the gas at the inlet is sucked into the impeller. The impeller accelerates the gas and discharges it through the diffuser and housing.
The working principle of the blower is based on the action of centrifugal force.
When the impeller rotates at high speed, the gas is accelerated under the action of centrifugal force, resulting in a pressure difference.
The pressure of the gas at the inlet is lower, while the pressure of the gas at the outlet is higher, so the gas will flow from the inlet to the outlet along the pressure gradient.
The working efficiency of a blower is related to factors such as the design of the impeller, the layout of the diffuser and casing, and the power of the motor.
In practical applications, we need to choose suitable blowers according to specific needs to improve ventilation efficiency and save energy.
