DCS fault prevention and maintenance measures sharing

Whether building new units or upgrading DCS, the configuration of systems and controllers should focus on reliability and load rate (including redundancy) indicators. The design of communication bus load rate must be controlled within a reasonable range, and the load rate of the controller should be balanced as much as possible to avoid the occurrence of "high load" problems that affect the safe operation of the system due to insufficient funds caused by large-scale involvement.

Summary of principles and methods for selecting various flow meters

Since its first industrial application in China in the late 1950s, electromagnetic flowmeters have been rapidly used and developed in flow measurement in the 1970s and 1980s. The working principle of an electromagnetic flowmeter is based on Faraday''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''

30 common faults and their solutions in on-site instruments

There is a problem with the instrument, and the reasons are quite complex. It is difficult to find the root cause at once. At this time, it is necessary to remain calm and analyze in stages. Firstly, analyze which unit the cause lies in, which can be roughly divided into three stages: on-site detection, intermediate transmission, and terminal display; At the same time, seasonal factors should also be considered, such as preventing high temperatures in summer and freezing in winter; When the para
