This post was last edited by zshiwei2008 on 2015-12-16 08:25. Points system for the daily question: Participation – 1~3 points; Correct answer – 5 points; In-depth analysis – 5~10 points. The answer is provided the next day. Due to limited capabilities, I am unable to provide more in-depth explanations for each question; therefore, on the second day, in addition to offering reference options, I will also remove the restriction on reading replies. I hope that all candidates can learn from one another and improve together! Daily Question (2015-12-10): 1. “When designing the layout of pumps, they should be arranged as closely as possible in a line, with the motor ends aligned and facing the road.” Which of the following statements regarding the pump layout is correct? A. The distance between pumps depends on their size; it is generally not less than 1.0 m. B. The distance between twin-row pumps is generally not less than 1.5 m. C. The distance between a pump and a wall is generally not less than 1.2 m to allow for easy passage. D. The foundation of a pump is generally 400–500 mm above the ground level. 2. Please indicate which of the following data regarding safety distances is incorrect. A. The distance between rotary machines should be at least 1.5 m. B. The distance between storage tanks should be at least 0.4–0.6 m. C. The distance between heat exchangers should be at least 1.0 m. D. The distance between towers should be 1.0–2.0 m. Answer: 1. C. This is the correct answer. Solution: The distance between pumps should generally be at least 0.7 m, while the distance between two rows of pumps should be at least 2.0 m. The pump foundations are usually raised 100–200 mm above the ground level. A, B, D are incorrect answers. 2. A. Correct answer. Solution: According to the \"relevant dimensions for workshop layout design and the safety distances between equipment,\" the distance between rotary machines should be no less than 0.8–1.2 m. B, C, and D are incorrect options.
