Abstract:
This study touches deeply into the issues inherent in two typical heat exchanger structures, including excessive flow resistance and insufficient heat exchange efficiency. An optimized design solution is proposed, involving larger coil diameter, dual-coil structure, and a removable cleaning mechanism. In the end, it analyzes the application of the optimized heat exchanger in mechanical seal systems of high-risk chemical pumps. This provides a theoretical basis for optimizing mechanical seal cooling systems in high-risk chemical pumps, effectively enhancing the reliability and safety of chemical equipment operation.
