摘　　要：水蒸汽喷射泵设计过程计算量大且繁琐、效率低,还易引入误差,使设计出的喷射泵性能达不到要求。本文对蒸汽喷射泵的设计理论进行了推导,并结合水和水蒸汽热力学性质计算公式IAPWS-IF97,将水蒸汽的热力学性质的计算和结构设计理论程序化,建立了蒸汽喷射泵结构尺寸计算系统。通过算例证明了所建蒸汽喷射泵结构尺寸计算系统具有较高的准确性和可靠性,提高了水蒸汽喷射泵的设计效率。A large amount of calculation should be done in the verbose design process of the steam jet pump, so the efficiency is low and errors are easily brought in, which causes the performance of pumps not to reach the requirements. The calculating system of the size of the steam jet pump structure was established based on the design theory and IAPWS-IF97 which were programmed both in the thermodynamic features and the structure design theory. The system was used to design a pump and the result proves that the system has high accuracy and reliability, and therefore the efficiency of the design is oromoted.
