摘要: 为满足连续式跨声速风洞对主回路驱动压缩机运行范围宽广、气动性能优良、转速控制精度高、密封严密、喘振预防安全可靠的特殊要求,开展0.6 m连续式风洞驱动压缩机针对性设计,并进行机械运转试验、气密性试验、转速控制精度测试试验、热力性能试验、喘振预防试验验证。根据一体化设计理念,对压缩机进气室、排气室分别与风洞第1拐角段和第2拐角段整体设计,使结构紧凑、流动均匀、压力损失降低;采用充气密封和设置放空腔等设计,有效防止了润滑油泄漏到风洞内流道以及风洞内部试验气体向洞体外泄漏和风洞外部的湿空气进入风洞内部;基于主从控制模式和矢量控制技术,成功实现了两台电机的双端同步拖动。试验结果表明:0.6 m连续式风洞驱动压缩机设计合理,气动性能优良,运行平稳,密封效果良好;压缩机转速控制精度优于0.03%,防喘振控制安全可靠。

Abstract: In order to meet the special requirements of continuous transonic wind tunnel for the main circuit driven compressor, including wide operating rang, excellent aerodynamic performance, high rotational speed control accuracy, tight sealing, and safe and reliable surge prevention, a compressor was designed for 0.6 m continuous transonic wind tunnel, and the test verification was also made through mechanical running test, air tightness test, rotational speed control accuracy test, thermal performance test, and surge prevention test. The compressor's inlet chamber is integrated with the first corner of the wind tunnel and its outlet chamber is integrated with the second corner by adopting the integrated design concept. The structures of inlet and outlet chambers are compact, the gas flow is uniform, and the pressure loss is lower. The gas seal and cavity are used to effectively prevent the leakage of lubrication oil into the wind tunnel, the leakage of test gas out of the wind tunnel and the leakage of wet air into the wind tunnel. The master-slave control mode and vector control technology are used to realize the synchronous driving of two motors successfully. The test results show that the design of compressor for 0.6 m continuous wind tunnel is reasonable, of which aerodynamic performance is excellent, operation is stable, sealing effect is good, speed control accuracy of compressor is better than 0.03%, and surge prevention is safe and reliable.
