Answer: Perform a series of tests to check the discharge pressure, capacity, and energy efficiency, and compare the results with the manufacturer’s specifications.
A. Dust content B. Oil content C. Dew point temperature D. Pressure fluctuations Answer: B Analysis: Oil mist emissions violate environmental regulations, and environmentally friendly oil-free air compressors combined with environmental management system certification can ensure compliance.
A. Water lubrication B. Oil lubrication C. No need for lubrication D. Special lubricant lubrication Answer: D Analysis: Oil-free air compressors usually use special lubricants to cool and lubricate parts to ensure the purity of compressed air.
Answer: It should be installed in a cool, dry place with adequate ventilation and away from sources of heat and moisture.
Answer: The main features include energy efficiency, low pressure operation, oil-free water lubrication, and high reliability.
Answer: The main features include energy efficiency, low pressure, oil-free operation, and water lubrication, providing pure compressed air suitable for industries with high air quality requirements.
