AI Technical Summary
Technical Problem
The existing motor cooling fan protective cover is icing up, which reduces the airflow capacity and affects the operation of the equipment. In addition, the existing de-icing method is inefficient and requires shutdown.
Method used
It employs an air pressure monitoring component and an air pressure de-icing component, which monitor the air pressure inside the protective cover and control the high-pressure gas purging to achieve automated de-icing.
Benefits of technology
The system achieves automated de-icing of the protective grid, avoiding manual intervention and downtime, and ensuring normal equipment operation.
