Answer: “Low pressure” refers to the compressor’s ability to operate at relatively low pressure levels, making it suitable for applications that require low-pressure 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: 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. Higher cost B. Limited scope of application C. Maintaining complex D. Compressed air has high oil content Answer: D analysis: The shortcomings of oil-free air compressors include high cost and limited scope of application, but low maintenance costs, compressed air…
Answer: It consumes less energy and operates more efficiently, resulting in lower operating costs.
A. Higher B. Lower C. Same as oil injection air compressor D. The answer cannot be determined: A Analysis: The manufacturing cost of oil-free air compressors is usually high, and the initial investment is large, but the long-term maintenance cost is low.
