Answer: According to the provisions of JB/T 53056-1999 "General Oil-Injected Screw Air Compressors", the vibration intensity of screw air compressors should not exceed 7.1mm/s. When the vibration of the air compressor exceeds this requirement, the most likely harm to the air compressor is: the connecting pipes of the air compressor leak under the influence of vibration, such as the outlet expansion joint cracks due to vibration. More serious harm will accelerate the damage of the air compressor bearings and reduce the overall life of the air compressor. Therefore, this regulation must be strictly observed during the operation of the air compressor.
