A. lower
B. higher
C. Same as oil-free air compressor
D. unable to determine
Answer: B
Analysis: The lubricating oil from the oil-sprayed air compressor will be partially mixed into the compressed air, resulting in a high oil content in the compressed air.
Answer: It offers superior energy efficiency, lower maintenance costs, and a longer lifespan.
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.
A. Cylinder volume × speed × number of cylinders B. Gas production × efficiency coefficient C. Theoretical exhaust volume ÷ temperature correction coefficient D. Standard state gas production × altitude correction factor Answer: A Analysis: Discharge…
Answer: It ensures the purity of compressed air, which is essential for food safety and quality.
Answer: The competitive advantages include high energy efficiency, no oil contamination, low maintenance costs, long service life, as well as strong brand influence and technical support.
