4.2. Compressor vibration
Measuring points of compressor vibration are the following: V1/1, V1/2, V1/3 ÷ V6/1, V6/2, V6/3. For workstation no. 6 before modernization the following maximum speeds of vibration were reported: 5.07; 3.99; 3.86; 3.85 mm/s. After the modernization the following maximum speeds of vibration were reported: 1.19 ; 1.09 ; 0.983 ; 0.964 mm/s. It is apparent that the speed of vibration for these compressors decreased even fourfold.
An average speed of compressor vibration was 2.8 mm/s for motor compressor no. 6 before the modernization and 0.53 mm/s after the modernization, which is considered a very good value.
