【摘要】 针对沈阳热电厂4号机组存在的滑负荷问题,通过测试分析、计算分析,确定主油泵出口压力波动为滑负荷问题的主要原因;通过模拟试验,将REXA执行器直接安装在油动机错油门上,解决了滑负荷问题,为电液调节系统改造提供了一定参考。更多还原

【Abstract】 In view of the load swing problem of No.4 steam turbine in Shenyang Thermal Powe r Work, through testing, calculating and analyzing, make sure that the pressure swing of the pump is the main reason of load swing. Through simulated test, sett ing the REXA Integrative Actuator on pilot valve and driving it directly, settle d the load swing problem. It provides the reference for the transform of Electrohydraulic Control System .更多还原
