AI Technical Summary
Traditional air-suspended blowers are prone to problems such as component deformation and failure, and bearing damage in high-temperature environments. Existing cooling methods have poor heat dissipation effects and are difficult to operate stably in fields such as nuclear power and chemical industry.
The cooling system combines air-cooled and liquid-cooled circuits. The air-cooled circuit cools the air by circulating gas, while the liquid-cooled circuit cools the air by circulating coolant. Combined with heat insulation plates to block heat, a multi-level cooling mechanism is formed.
This improves the stability and reliability of air-suspended blowers in high-temperature environments, meeting the high-temperature operation requirements of industries such as nuclear power and chemical engineering.
