C. building construction
D. pharmaceutical industry
Answer: C
Analysis: Due to the high oil content of compressed air, oil-injected air compressors are usually used in occasions where the purity of compressed air is not high, such as construction.
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.
A. 0.05 bar B. 0.1 bar C. 0.2 bar D. 0.5 Bar Answer: B Analysis: The pressure drop per 50 meters of pipeline increases by 0.1 bar, and the flow loss is about 2%.
Answer: The biggest difference is that the GWL Series compressor does not use lubricating oil during the compression process, providing oil-free compressed air.
A. Volume efficiency loss B. Air compressor brand premium C. Intake air temperature D. Filter pressure loss answer: B Analysis: Gas production is affected by mechanical efficiency, environmental factors and system matching, and has nothing to do with the brand.
Answer: It alerts the operator with visual and audible warnings, and provides diagnostic information to help identify the problem.
