工作温度和回水温度对水喷射泵性能的影响
Effect of water supply and return temperature on performances of water injector
摘要：
比较了其他参数相同而流体工作温度和回水温度分别变化10 ℃时，二者对水喷射泵性能的影响。结果表明，回水温度变化对水喷射泵的截面比和性能影响较大，因此在供热系统运行中应尽量减小回水温度的波动。

Abstract：
Compares the effects when water supply and return temperatures vary 10 ℃ respectively while other parameters remain unchanged. As a result, the water return temperature affects cross-section area ratio and performances of the injector more heavily, hence the water return temperature should be kept as steady as possible during operation of a heating system.
