But failure will cause the device to stop or accident, all kinds of trouble to the early detection and appropriate treatment it is very important. Our synthetic ammonia process using multiple sets of SUPCON JX-300XDCS control, control is stable and reliable. As raising the level of automation, DCS control system (DCS) has gradually replaced the conventional instrument, its superiority has been widely accepted by operators. But failure will cause the device to stop or accident, all kinds of trouble to the early detection and proper treatment is very important. Our synthetic ammonia process using multiple sets of SUPCON JX-300XDCS control, reliable control for some problems, based on years of maintenance experience, we summarize a set of effective identification and treatment failure. 1, view the monitor screen of data When the following occurs, indicating control problems, computer maintenance personnel should be immediately repaired to the scene while processing operator. (1) the same time constantly changing data, and the number of data or all data remain unchanged. (2) control group screen, manual can not switch automatically, or manually input data, is confirmed, then restore the original data, modification of them. (3) the trend graph screen, several trends are the same as the straight line. (4) monitor screen, multiple data also volatile. Determine whether fluctuations in the data process on the relevant parameters, if the relevant parameters and computer personnel to inform instrument check to see if the fluctuations of a regulation system parameters change, while related to manually adjust the system hit the state, if necessary, to the site regulation. Aqueous solution of the whole cycle of the device, such as urea synthesis reactor pressure is normal for the l9.67MPa, if a sudden large-scale fluctuations in time will inevitably lead to downstream pressure system Low System pressure fluctuations, this situation is due to several relevant parameters in a parameter fluctuations Other Parameters, not the fault control system itself. If the fluctuations in the data process no direct impact on each other, then the card may be parts of a computer failure, related to self-tune the system immediately hit the manual adjustment, if necessary, to adjust the scene, while a team of officers to inform computer and instrument . 2, the operators work station When they find an action stations crash, monitoring data does not refresh the screen, adjust the screen does not work, see the top right of the system warning light is normal, and check for other operating station is working properly, if normal, only the operating station a problem, notify the maintenance personnel computer repair. If the other operator station data unchanged, compared with system communications network failure, immediately notify maintenance personnel check the operation of network equipment, for repair.
