C. 15-25%
D. 30-40%
Answer: C
parsing: The clearance volume of reciprocating air compressors causes a 15-25% reduction in efficiency.
What aspect of the company does ISO 50001 certification focus on? A. Quality management system B. Environmental Management System C. Energy Management System D. Occupational health and safety management system answer: C analysis: ISO…
Answer: The isothermal compression is achieved through the use of water lubrication, which helps to dissipate heat more effectively.
A. Higher B. Lower C. Same as oil injection air compressor D. The answer cannot be determined: B Analysis: Oil-free air compressors do not need to replace lubricants and oil filters, so the maintenance cost is low.
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.
Answer: It can monitor parameters such as discharge pressure, temperature, motor current, and lubrication water level.
