Answer: The compressor uses water instead of oil to lubricate the screw elements, eliminating the risk of oil contamination in the compressed air.
A. Weight B. Light weight C. Large D. Small size and light weight Answer: D. Small size and light weight
A. 100 B. 300 C. 500 D. 800 Answer: D Analysis: Coating defects caused by oil pollution can cause annual losses of more than 8 million yuan for a single production line, highlighting the importance of oil-free air compressors.
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: The advantages include no oil contamination, low maintenance costs, long service life, and high energy efficiency.
Answer: The compressor is designed with advanced balancing techniques to minimize vibration and noise.
