Answer: The compressor uses water instead of oil to lubricate the screw elements, eliminating the risk of oil contamination in the compressed air.
A. There are oil screw air compressors, oil-free screw machines, centrifuges, vacuum pumps, etc. B. Air compressors used in homes and air compressors used in commercial places C. Air compressors for the oil and natural gas industry, air compressors for the construction industry D. Manufacturing air compressors,…
A. Price and brand B. Performance, price and brand C. Market share and technological innovation D. Production date and transportation method Answer: C. Market share and technological innovation
A. Water-cooled and air-cooled B. Oil cooled and air cooled C. Water cooling and oil cooling D. The answer cannot be determined: A Analysis: The cooling system of oil-injected air compressors usually includes two types: water-cooled and air-cooled, which are used to cool the compressor and compressed air…
A.≤0℃ B.≤-10℃ C.≤-20℃ D.≤-30℃ Answer: C Analysis: The spraying process requires a compressed air dew point of ≤-20℃ (PDP) to prevent moisture condensation from affecting the coating quality.
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.
