轴流风机静叶调节系统改进与应用
|
摘要
AV50-12轴流式主风机是一种12级全静叶可调式轴流压缩机,静叶调节系统为典型的电液伺服控制系统。由于长时间受油质污染、环境等因素的影响,静叶角度调节存在控制精度差、飘移、响应迟缓等问题。为此对该系统进行改进,采用REXA电液执行器替代原静叶调节系统。系统改造后,不仅解决了原调节系统存在的问题,并且提高了系统可靠性,同时大大简化了系统结构,节约了能源。
AV50-12 axial main fan is a 12-stage adjustable axial compressor with static blade. Due to the influence of oil pollution,environment and other factors for a long time, there were problems in the static blade regulation, such as poor control accuracy and slow response. So the system was improved. The original stator blade control system was replaced by REXA electro-hydraulic actuator.After the system transformation, the existing problems of the original adjustment system were solved, the system reliability was improved, and the system structure was greatly simplified, and energy consumption was decreased.
