Issues related to cylinder vibration standards in reciprocating compressors
Thread Content
Given that, according to the vibration meter measurements, the axial vibration level of the cylinder reaches almost 9 mm/s, how can we determine whether the axial and radial vibration values of the cylinder are within a reasonable range? According to the GB/T7777 standard, a symmetric compressor is considered qualified if the vibration rate is no more than 18 mm/s; but won’t the cylinder fly off in that case? So how exactly should this vibration value be properly evaluated? 、?
Same question – is there anyone skilled enough to answer it? Also, the graph in GB/T7777 has messy lines; does anyone have a clearer version?
