What are the main characteristics of oilless air compressors?
- A. Produce lubricating oil
- B. No production of lubricating oil
- C. Need to change lubricating oil frequently
- D. high noise
Answer: B. No production of lubricating oil
A. The actual volume of compressed gas output by the air compressor per unit time B. Gas discharge capacity after considering efficiency loss C. Theoretical value of the geometric volume swept by the piston per unit time D. The value that needs to be converted to the standard state will answer…
Answer: Follow the manufacturer’s instructions for safe shutdown procedures to avoid damage to the compressor.
A. Lower B. Higher C. Same as oilless air compressor D. The answer cannot be determined: B Analysis: The lubricating oil from the oil-injected air compressor will be partially mixed into the compressed air, resulting in a high oil content in the compressed air.
A. Compressed air demand B. Industry Applications C. Budget D. Equipment life answer: A analysis: When selecting an air compressor, the primary consideration is the compressed air demand, including purity requirements and use scenarios.
Answer: The noise level is relatively low, typically below [Z] dB(A).
