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.
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.
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. Adopt energy-efficient design B. Increase noise C. Reduce power D. Reduce maintenance Answer: A. Adopt energy-efficient design
A. An altitude of 1500 meters causes intake pressure loss B. After-treatment equipment pressure loss 6% C. The capacity of the air storage tank is too large D. The ambient temperature is too high Answer: C Analysis: Insufficient capacity of the gas storage tank is a problem. Too large will not affect the gas production…
A. Portable air compressor B. Industrial air compressor C. Medical air compressor D. Mine air compressor Answer: A. portable air compressor
