A shock-absorbing installation device for a centrifugal fan

technical field

The utility model relates to a shock-absorbing installation device for a centrifugal fan, which belongs to the technical field of centrifugal fan installation.

Background technique

The centrifugal fan is based on the principle of converting kinetic energy into potential energy. It uses a high-speed rotating impeller to accelerate the gas, then decelerates, changes the flow direction, and converts kinetic energy into potential energy (pressure). Centrifugal fans, as important supporting equipment in industry, are widely used in electric power, cement, petrochemical, coal, mining and environmental protection fields, and are also used in cooling and ventilation of air conditioning equipment and household appliances, wind tunnel wind sources and hovercraft Inflatable and propulsion fields.
