Answer: The isothermal compression is achieved through the use of water lubrication, which helps to dissipate heat more effectively.
A. Wear of cylinder head and air liner B. Piston and piston rod damage C. Valve assembly failure D. These are all answers: D. all of the above are
Answer: Water lubricates the screw elements, cools the compressor, and helps to maintain optimal operating conditions.
A. Oil injection air compressor B. Oil-free air compressor C. Both can be D. The answer cannot be determined: B Analysis: The semiconductor manufacturing industry has extremely high requirements for the purity of compressed air, so oil-free air compressors are usually chosen.
Answer: The motor power typically ranges from [C] to [D] kW.
A. 50% B. 60% C. 75% D. 80% answer: C analysis: Environmentally friendly oil-free air compressors reduce oil pollution, thereby reducing the frequency of filter replacement and optimizing maintenance costs.
