According to the urea pump performance test system and a method thereof, software parameters in the host computer are calibrated and the control circuit board is instructed to control the diesel vehicle post-processing device to carry out test work; performance such as liquid conveying, spraying, unfreezing, pumpback and spraying precision of the urea pump can be tested, and a matching test can beconducted on the urea pump in the whole diesel vehicle aftertreatment device. Compared with an actual loading test, the device provided by the utility model is simple in structure system, economicaland practical, can complete the function verification and parameter calibration work of the actual loading test, can greatly improve the convenience of the diesel engine aftertreatment device test, and effectively shortens the development period of a urea pump and components thereof in a diesel vehicle aftertreatment device. 本实用新型提供的尿素泵性能的测试系统及其方法采用上位机中软件参数标定并指令控制电路板控制柴油车后处理装置进行测试工作，可以对尿素泵输液、喷射、解冻、回抽和喷射精度等性能进行测试，也可以对尿素泵在整个
