摘要
本文从理论方面阐述和用实验数据证实,长喉管射水抽气器效率高,能耗低,并指出改进短喉管射水抽气器工作量不很大,花费不多,见效快,效益显著。同时还介绍了设计改进步骤和计算方法公式。
This paper presents ample experimental data which show that the improvement ofwater-jet pumps from short throats into long ones costs a little work and expense and the im-proved throat is efficient and energy-saving. And then, it also introduces the designing stepsand calculating formulas.
