AI Technical Summary
Existing technologies struggle to achieve wide head range coverage, ensure measurement accuracy, and flexibly switch between multiple operating conditions on micro-sized pump-turbine test benches. They also present challenges related to thermal barriers and complex flow path design, resulting in low test accuracy and efficiency.
A multifunctional test bench for miniature water pumps and turbines was designed. It adopts a dual-pump series-parallel switching water supply and pressurization system, combined with a bypass pipeline and pressure stabilization system for turbine operating conditions, to achieve wide head range coverage and flow reversal. Through a dual-range flow measurement system and a simple flow path structure, it ensures measurement accuracy and ease of operation.
It enables coverage of a wide head range from 10m to 200m in small closed systems, reduces throttling losses, improves testing accuracy and ease of operation, and lowers construction and operating costs.
