Axial fan

Introduction

Axial fan, is the airflow in the same direction of the wind blade (the flow direction and axis of the wind), such as electric fans, air conditioning external fans are axial flow Way to run the fan.

Axial fan is also a local ventilator, a fan commonly used in industrial and mining companies, which are different from a general fan, its motor and blanks are in a cylinder, the shape is a cylinder For local ventilation, convenient installation, the ventilation effect is obvious, safe, can be sent to the designated area.

Composition

Axial ventilator is mainly from 1-hub; 2-blade; 3-axis; 4-housing; 5-intensive; 6-streamlined; 7-rectifier; 8-diffuser. As well as the venting and impeller composition. The inlet wind is composed of a haindier and streamline, and the impeller is composed of hub 1 and blade 2. The impeller is fixed to the shaft 3 together to form a rotor of the vent, the rotor is supported on the bearing.

When the motor drives the venting of the vent, there is a relative airflow through each blade.

Working principle

However, the latter is the power to the wing and support the aircraft, while the axial fan is fixed and the air is moved. The gas stream enters an axial fan by the current vapor, and after the leader, the energy is obtained, and the energy is obtained in the leaf dynamic leaf, and the post-passage, the air flow can be converted to a static pressure, and the last gas flows through the diffuser. , The kinetic energy of a portion of the axial airflow is converted to a static pressure.

Classification

Press material Classification: Steel fan, FRP fan, plastic fan, PP fan, PVC fan, aluminum fan, stainless steel fan, etc.

Use: explosion-proof fan, anti-corrosion fan, explosion-proof anti-corruption fan and other types.

Classify: pipeline, wall type, post, fixed, rain, dust, motor external type.

Civil construction and other venues ventilated or strengthen heat dissipation. If the casing is removed, it can also be used as a free fan, and can be installed in the longer exhaust pipeline in series to improve the pipeline Wind pressure.
