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.
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.
Answer: The main features include energy efficiency, low pressure operation, oil-free water lubrication, and high reliability.
A. Screw B. Piston C. Centrifugal wheel D. Scroll disk answer: B. piston
A. Stable growth B. Volatility growth C. Declining year by year D. Stagnation Answer: A. steady growth
A. Lower B. Higher C. Same as oilless air compressor D. The answer cannot be determined: B Analysis: The lubricating oil from the oil-injected air compressor will be partially mixed into the compressed air, resulting in a high oil content in the compressed air.
