A.≤0℃ B.≤-10℃ C.≤-20℃ D.≤-30℃ Answer: C Analysis: The spraying process requires a compressed air dew point of ≤-20℃ (PDP) to prevent moisture condensation from affecting the coating quality.
Answer: Regular inspections of the air filter, lubrication system, and motor can help prevent premature wear and tear.
Answer: It uses water lubrication and does not produce any oil-related emissions.
A. Increase energy consumption B. Reduce noise C. Frequent start-ups and stops lead to loss D. Increase the exhaust temperature Answer: C Analysis: Insufficient capacity of the air storage tank will lead to frequent start-ups and stops of the air compressor and increase loss.
