Performance testing device for jet pump

The utility model relates to the field of aircraft fuel systems, and particularly discloses a jet pump performance testing device which comprises a main fuel tank and an auxiliary fuel tank. A to-be-tested jet pump is arranged at the upper end in the main oil tank, a first inlet of the jet pump is communicated with the bottom of the auxiliary oil tank through a pipeline, and a second inlet of the jet pump extends below the liquid level of the main oil tank through a pipeline; and the outlet of the jet pump guides the mixed liquid into the auxiliary oil tank through a pipeline. The test device is simple in structure and high in integration level, and can simulate and test the performance of the jet pump at different heights and fuel temperatures. 本实用新型涉及飞机燃油系统领域，具体公开了一种引射泵性能测试装置，包括主油箱、副油箱；待测试引射泵设置于主油箱内上端位置处，引射泵第一入口与副油箱底部通过管路连通，引射泵第二入口通过管路伸入主油箱液面下；引射泵出口通过管路将混合液体导入副油箱中。本实用新型是一种结构简单、高集成度的测试装置，模拟测试不同高度及燃油温度下引射泵性能的功能。
