Answer: “Low pressure” refers to the compressor’s ability to operate at relatively low pressure levels, making it suitable for applications that require low-pressure compressed air.
A. Inspect reinforced gas piping B. Replace the leaking valve C. Check or replace air valve D. These are all answers: D. all of the above are
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.
A. Compressed air pure B. Low manufacturing cost C. Simple maintenance D. Low energy consumption Answer: A Analysis: The main reason why the food production industry chooses oil-free air compressors is that its compressed air is pure and meets the hygiene requirements of food production…
A. Higher B. Lower C. Same as oil injection air compressor D. The answer cannot be determined: A Analysis: The manufacturing cost of oil-free air compressors is usually high, and the initial investment is large, but the long-term maintenance cost is low.
Answer: Regular inspections of the air filter, lubrication system, and motor can help prevent premature wear and tear.
