The working principle of high pressure centrifugal fan

The electric motor starts and drives the impeller to rotate through a transmission device (such as a direct connection or belt drive).

Axial fan, also known as local fan

Axial flow fan refers to the fan whose air flow direction is in the same direction as the axis of the wind blade, that is, the gas flows parallel to the fan axis. It works similar to the wing of an airplane, but the axial fan is fixed in position and moves the air. When the impeller rotates, the gas enters the impeller from the inlet axially, and the energy rises after being pushed by the blade, and then flows into the guide vane. The guide vane changes the direction of the deflected air flow into axial flow, at the same time, the gas is introduced into the diffuser tube, and the kinetic energy of the gas is further converted into pressure energy, and finally into the working pipeline.

Axial fan is mainly composed of impeller, shell, motor and other parts.

Axial fan is mainly composed of impeller, shell, motor and other parts. The bracket is connected with the shell air duct by section steel. Among them, the impeller is composed of a hub and a blade, which are fixed together with the shaft to form the rotor of the fan. The rotor is supported on the bearing, and when the motor drives the fan impeller to rotate, there is a relative air flow through each blade. In addition, the axial fan also includes a collector, a streamline body, a rectifier, a diffuser and other components.

Axial fans are usually used in situations where the flow requirement is high and the pressure requirement is low

Axial fans are usually used in situations with high flow requirements and low pressure requirements, such as ventilation in factories, warehouses, offices, homes and other places, and can also be used for cold fans (air coolers), evaporators, condensers, spray dust removal, etc. In addition, there are axial flow fans for mining and anti-corrosion and explosion-proof axial flow fans, which can be used to transport explosive, volatile and corrosive gases.

Conversion transformation and energy saving

When the axial fan is started, the current of the motor will be 5-6 times higher than the rated value, which will not only affect the service life of the motor, but also consume more electricity. Therefore, the conversion transformation is very necessary. The inverter can realize the soft start of the motor, achieve the purpose of energy-saving speed regulation by changing the input voltage frequency of the equipment, and provide the equipment with over-current, over-voltage, overload and other protection functions.
