bg4.png [Daily Question] [Static Equipment Exchange Edition...Question 95] Adapted multiple choice question on April 5, 2019...Happy Holidays......................................................................The question comes from the book: I hope everyone will point out the lax adaptation of NB/T 47041-2014 "Tower Container". If you have good suggestions, you can also reply with comments and no hesitation will be rewarded. .................................................................................... Please fill in the answers (single choice, single choice, single choice) in order. Bonus rules: Participation will reward 1 wealth, and correct answers will reward 3 wealth for each item, with a maximum of 10 wealth. .................................................................................1. For multi-cavity tower vessels composed of 2 or more pressure chambers, the test pressure of each pressure chamber is determined according to (), and each pressure chamber is subjected to a pressure test separately. A. Work pressure ； B. Calculate pressure ； C. Design pressure (or maximum allowable working pressure) ； ---------------------2. For multi-cavity tower vessel testing: a) Check the stability of common components under test pressure ； b) If the stability requirements cannot be met, () should be performed first, and then the withstand voltage test should be performed after passing the test. When conducting a pressure test, a certain pressure should be maintained in adjacent pressure chambers so that the pressure difference in each pressure chamber does not exceed the allowable pressure difference at any time during the entire test process (including pressure increase, pressure maintenance and pressure relief). This requirement and the allowable pressure difference value should be indicated on the drawing. ； A. Leak test ； B. Leak check ； C. Air tightness test ； ---------------------3. For tower vessels that cannot be subjected to pressure test according to standards, the manufacturing unit shall propose safety measures that should be taken to exempt the pressure test on the premise of ensuring the safe operation of the tower vessel, and indicate this on the drawing after approval by the technical person in charge of the design unit. () A. Correct ； B. Error ； ---------------------Answer: (Investigating the pressure test of tower vessels) 1. C 2. B 3. B (The design unit should propose...)
