[Daily Question 20090205] What should the automatic adjustment system do during system cold debugging? Summarize: See the reply on the 2nd floor
Use analog signals to check the basic errors of the system and the quality of pipeline connections. Determine the action direction of the regulator, actuator, valve positioner, etc., and it should comply with the design regulations and process operation requirements. The error and working performance of the regulator and actuator should also be checked. Conduct open-loop tests to check the correctness of the system.
During cold debugging, each unit in the automatic regulating system should be debugged and calibrated individually, including the transmission unit, regulating unit, actuator, air system, etc. This post was last edited by abkzp123 on 2009-2-5 20:54 ]
What work should be done during cold debugging of the automatic adjustment system? answer: Use analog signals to check the basic errors of the system and the quality of pipeline connections. Determine the action direction of the regulator, actuator, valve positioner, etc., and it should comply with the design regulations and process operation requirements. The error and working performance of the regulator and actuator should also be checked. Conduct open-loop tests to check the correctness of the system.
Is the second joint calibration of the system a cold debugging or a hot debugging? Is the joint test run cold debugging or hot debugging? Second joint calibration (carry out joint debugging of each analog signal to confirm that the connection is correct and the display is normal. Conduct linkage debugging of each adjustment signal to confirm that the valve operates normally, the air is opened and closed correctly, and the positive and negative effects are determined according to the process. Contact the field device to make sure that the DO signal controls the field device to operate normally and the DI signal displays normally. Contact the on-site equipment to confirm that the control scheme operates normally, the interlock output is normal, and can meet the needs of process start-up. )
