精轧液压活套压力传感器故障快速判断与更换

Fast diagnosis of hydraulic loop transducer fault and exchange of the troubled device

武钢薄板坯连铸连轧生产线生产节奏快,而精轧液压活套压力传感器工作环境差,温度高,容易损坏,故障处理和更换时间过长甚至造成断浇。通过对液压活套压力传感器故障的判断、分析,研制出一种快速更换压力传感器的方法,即测压头、测压线以及传感器外挂的方法。实施此方法以后,彻底消除了因液压活套压力传感器引起的连铸断浇。

In the CSP line of WISCO the production rhythm is very fast and the environmental condition for installation of the hydraulic loop transducer is very tough and atmospheric temperature in the area is also quite high and therefore damage of the device frequently occurs in the process of installation. Furthermore longer duration time for device exchange and trouble shooting may cause termination of hot metal casting. By way of diagnosis and analysis on the fault of the hydraulic loop transducer a method of fast exchange of the transducer is developed according the the knowlege of mechanics, namely a method of installation of the hydraulic loop transducer by a pressure measuring cell and a pressure measuring wire and out hanging of the transducer. Ever since implementation of this method the accident of casting termination arising from the hydraulic loop transducer trouble has been completely eliminated.
