Answer: The compressor uses water instead of oil to lubricate the screw elements, eliminating the risk of oil contamination in the compressed air.
Answer: The main features include energy efficiency, low pressure, oil-free operation, and water lubrication, providing pure compressed air suitable for industries with high air quality requirements.
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.
A. Small market share B. Few product types C. Insufficient technological innovation D. Large market share and rich product categories Answer: D. Large market share and rich product variety
A. Spraying and sandblasting operations B. Home use of C. Commercial places use D. Agricultural production uses answer: A. Spraying and sandblasting operations
Answer: By adopting water lubrication technology, it avoids oil contamination of compressed air and uses an efficient oil-air separation system to ensure the purity of compressed air.
