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.
Answer: Common faults include high temperature, low pressure, and motor overload.
Answer: It can be determined by observing the pressure differential indicator of the water filter or based on usage time and water quality.
A. Pressure and temperature B. Oil quantity and pressure C. Temperature and oil quantity D. The answer cannot be determined: A Analysis: The control system of an oil-free air compressor is mainly used to monitor and control the operating parameters of the compressor, such as pressure and temperature.
A. 1-3% B. 8-12% C. 15-25% D. 30-40% Answer: C Analysis: The clearance volume of reciprocating air compressor causes a 15-25% efficiency decrease.
Answer: Water lubricates the screw elements, cools the compressor, and helps to maintain optimal operating conditions.
