简介:针对银川某液压厂数控机床工作在保压阶段液压泵功率浪费严重的情况,提出了一种应用开关磁阻电动机调速系统(SRD)降低液压泵输出功率以达到节能的方法。该系统采用TI公司电动机控制专用数字信号处理器(DSP)TMS320LF2407A为核心控制器,经过软硬件综合设计,最终实现了液压泵进入保压阶段时快速且稳定的降速从而到达了减少功率浪费的效果,使整个液压系统更节能。该调速系统的设计对液压动力装置减少功率浪费、降低生产成本有一定的参考价值。

简介:摘要GIS隔离开关分闸不到位是由操作机构决定的,操作机构的传动拐臂安装与设计角度有偏差,偏离正常运行轨迹,造成阻尼力矩的加大。因此,我们要重视在运输和安装过程中会对设备造成误差的影响因素,加强技术监督,完善设备管理,保证设备安全运行,从而确保电网安全运行。同时,在正常的运维工作中,加强对设备外观的检查,发现缺陷及时处理,确保缺陷得到根治。对于西北地区,春冬季节风沙较大、气温较低等都会影响到隔离开关操作机构的稳定运行。春检预试工作又是发生在这个阶段,所以操作前应提前认真对设备的外观进行检查,有冰雪应及时清理,有沙尘会影响润滑,应及时在机构输出轴、传动连杆、相间连杆等处的轴销、万向轴承处均涂抹润滑脂。
