Working Principle

When the impeller of the equipment is opened and rotated at high speed, the air of each part of the impeller will also be driven to rotate together. At this time, the air at the impeller position will be thrown out. As the centrifugal force acts on the edge of the impeller, a vacuum position will be formed at the impeller position. Then the outside air will continue to flow in under the action of the pressure difference, and then be added to the impeller position, so that the fan has the ability to inhale air.

Place the tunnel axial flow fan in a separate dust removal room and configure the corresponding air duct and dust cover, connect the dust collector and plug in the power supply to turn on the fan button. At this time, the dust-laden air will pass through the tunnel fan from the dust source. Dust hood, air inlet, etc. enter the box because the airflow will suddenly expand, so the flow rate will suddenly decrease, so that large particles will be separated from the dust-containing air under the action of their own weight. It comes and falls into the ash hopper, and other dust particles will also stay at the outlet position of the outer wall of the filter element due to the filtration, collision, static electricity, etc. of the filter element.

Performance Characteristics

1. Material selection of tunnel axial flow fan. Corrosion resistant materials can be selected according to the use environment. Starting from the physical and chemical properties, cost performance and many other factors, the strength is basically determined. From the data itself, the target material is safe.

2. Tunnel axial fan design. Excellent design can extend the service life of the equipment and ensure the safety of the equipment. For structural design, stress concentration tendency and gap environment are the main defects of accelerated corrosion design. When voids are generated, interstitial corrosion occurs due to changes in the chemical and electrochemical states of the internal solution. The appearance of the tunnel axial fan also needs to be well protected. Surface treatment is generally flange, galvanized, chrome plating, chemical plating, etc.
