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
parsing: The exhaust volume is determined by cylinder volume, speed and number of cylinders.
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.
A. 0.5-0.6 B. 0.7-0.85 C. 0.9-1.0 D. 1.1-1.2 Answer: B Analysis: When selecting the model, it needs to be multiplied by an efficiency factor of 0.7-0.85.
A. 50% B. 60% C. 75% D. 80% answer: C analysis: Environmentally friendly oil-free air compressors reduce oil pollution, thereby reducing the frequency of filter replacement and optimizing maintenance costs.
