AI Technical Summary
Technical Problem
Existing pump assemblies face issues with inconsistent cooling due to varying engine exhaust air, leading to potential frost formation and inadequate temperature regulation of the hydraulic system and engine.
Method used
A pump assembly with integrated air passages for coordinated heat exchange between the hydraulic system and air, using a controlled air source to maintain consistent cooling and heating, ensuring the hydraulic system is cooled while the engine is warmed.
Benefits of technology
The system effectively regulates temperature by adapting cooling and heating based on operational conditions, preventing frost formation and maintaining optimal performance.
