Thread Content
This post was last edited by “Back to Cambridge” on September 28, 2016, at 09:27. Starting today, the Chemical Engineering Theory section is launching the “Question of the Day” activity, aimed at helping everyone reinforce their fundamental knowledge in chemical engineering. Subsequently, series such as “Principles of Chemical Engineering”, “Mass Transfer and Separation”, “Chemical Thermodynamics”, and “Chemical Process Technology” will also be introduced. We hope for your active participation! Wishing you all a Merry Christmas~~ For replies to the “Question of the Day” activity, answers can be viewed directly; however, the thread will be closed after one day! ! To encourage everyone’s continued participation this year! Participation earns 3 wealth points, with an additional 4 wealth points for correct answers~~~ Short answer question: What measures should operators take for the maintenance of filtration equipment used in water treatment? Answer: The maintenance personnel submit a thermal machinery work order; according to the scope of the equipment to be maintained, they shut down the equipment in question, close the inlet doors of the filtration equipment, and open the bottom drain valves to drain all the water. Close the main air valve used for operating this filter, install the relevant control valves on the panel, and place warning signs in place.

Close the main air valve used for operating this filter, install the relevant control valves on the panel, and place warning signs in place.
First, the maintenance personnel submit a thermal mechanical work order. Next, depending on the scope of the equipment to be maintained, the equipment in question is taken out of service; the inlet doors of the filtration equipment are closed, and the bottom drain valves are opened to drain all the water. To shut down this filter, close the main air valve used for operation, operate the relevant control valves, and then place a warning sign in place.
