介绍一种新型射流——自振空化射流的设计原理、冲击压力特性、冲蚀破岩特性和现场应用情况。研究表明,以风琴管结构为基础设计的喷嘴可以产生强烈的自振空化射流,与锥角为 120°的普通锥形喷嘴相比,冲击压力脉动幅度和峰值分别提高24%和37%,冲蚀岩石效果提高1~2倍。自振空化射流已成功应用到石油工程中,研制出自振空化射流钻头、高压旋转自振空化射流处理近地层技术和自激波动注水技术,取得明显的经济效益。

A brushless electrically excited synchronous generator (BEESG) with a hybrid rotor is a novel electrically excited synchronous generator. The BEESG proposed in this paper is composed of a conventional stator with two different sets of windings with different pole numbers, and a hybrid rotor with powerful coupling capacity. The pole number of the rotor is different from those of the stator windings. Thus, an analysis method different from that applied to conventional generators should be applied to the BEESG. In view of this problem, the equivalent circuit and electromagnetic torque expression of the BEESG are derived on the basis of electromagnetic relation of the proposed generator. The generator is simulated and tested experimentally using the established equivalent circuit model. The experimental and simulation data are then analyzed and compared. Results show the validity of the equivalent circuit model.
