A. 1-3%
B. 8-12%
C. 15-25%
D. 30-40%
Answer: C
parsing: The clearance volume of reciprocating air compressors causes a 15-25% reduction in efficiency.
Answer: The flow rate range also varies depending on the specific model, usually covering from a few cubic meters per minute to tens of cubic meters per minute.
A.≤0.5%FS B.≤1%FS C.≤1.5%FS D.≤ 2% FS Answer: A Analysis: Environmentally friendly oil-free air compressors need to meet pressure fluctuations ≤ 0.5% FS (0.7-1.0MP…
Answer: They provide consistent, high-quality compressed air for textile manufacturing and laboratory applications.
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.
