汽轮机调节系统自动停车装置故障的处理

空压机汽轮机调节系统自动停车装置发生故障,速关油压泄不掉,联锁信号发出不跳车,查找原因,消除隐患,保证机组安全运行。     

冰机跑油原因分析及处理措施

由于浮环磨损造成间隙增大,使污油回油量增大,超过污油捕集器的处理能力,造成冰机跑油.通过对冰机低压缸低压侧浮环及其对应的污油捕集器采取相应的措施,保证冰机稳定运行.     

High thermal stable gold catalyst supported on La2O3 doped Fe2O3 for low-temperature CO oxidation

La2O3 doped Fe2O3 support was prepared by co-precipitation method,and gold was loaded by deposition-precipitation.Thermal stability of gold catalyst was enhanced considerably by La2O3 doping.Even when calcined at 500 oC for 12 h,the catalyst doped with La2O3 could convert 90% of CO at 28.9 oC,while the catalyst without La2O3 doping achieved 90% CO conversion at 43.5 oC.Characterization techniques,such as N2 adsorption-desorption,X-ray diffraction(XRD),transmission electron microscopic(TEM) and thermogravime...
