Rotating and torsional shaft vibration, as well as the vibration of drivers (electric motors, engines) and driven auxiliary equipment, are outside its scope and must be evaluated using the other applicable standards for those machine types.<\/p>\n

Does ISO 20816-8 Cover Flexible (Spring-Isolated) Foundations?<\/h2>\n

No \u2014 ISO 20816-8 applies to reciprocating compressors mounted on rigid foundations and does not define a separate zone table for flexible (spring-isolated) installations. For spring-isolated machines, the tool offers optional engineering guidance boundaries \u2014 A\/B at 9.0 mm\/s RMS, B\/C at 18.0 mm\/s RMS, and C\/D at 36.0 mm\/s RMS \u2014 extrapolated from the rigid-foundation values to reflect the additional frame motion that spring isolation permits. These guidance values are not part of ISO 20816-8, and an assessment based on them should not be reported as an ISO 20816-8 zone classification.<\/p>\n\n\n\n\n\n\n\n

Reciprocating compressors have significantly higher acceptable vibration levels than rotating machines. The Zone A upper limit for reciprocating compressors on rigid foundations is 7.1 mm\/s RMS \u2014 roughly five times the 1.4 mm\/s RMS Zone A\/B boundary for a medium-size rotating machine (ISO 20816-3, formerly ISO 10816-3, Group 2 on rigid support). This difference exists because the reciprocating mechanism inherently generates higher vibration that is considered normal operation.<\/p>\n\n\n\n\n\n\n\n\n\n

        ISO 20816-8 assessments require vibration velocity measurements in mm\/s RMS taken on the compressor frame or main bearing housings. Measurements should be taken at steady-state operating conditions in all three axes (horizontal, vertical, axial), with the highest value used for zone classification. Broadband measurements covering at least 2\u20131000 Hz are recommended.<\/p>\n

          For reciprocating compressors on rigid foundations, vibration velocity up to 7.1 mm\/s RMS is considered excellent (Zone A), and up to 14.0 mm\/s RMS is acceptable for unrestricted long-term operation (Zone B) per ISO 20816-8. For flexible (spring-isolated) foundations ISO 20816-8 does not define limits; the tool’s extrapolated engineering guidance uses 9.0 and 18.0 mm\/s RMS respectively.<\/p>\n

          No. ISO 20816-3 applies exclusively to rotating machines. Reciprocating compressors generate inherently higher vibration due to the piston-crank mechanism, and their acceptable levels are several times higher than typical rotating machine limits. Always use ISO 20816-8 for reciprocating compressors to avoid false alarms and unnecessary shutdowns.<\/p>\n

          Does ISO 20816-8 define limits for flexible (spring-isolated) foundations?<\/h3>\n

          No. ISO 20816-8 applies to reciprocating compressors on rigid foundations and defines zone boundaries for rigid installations only. The flexible-foundation values offered by the tool (for example, 9.0 mm\/s at the A\/B boundary versus 7.1 mm\/s for rigid) are extrapolated engineering guidance \u2014 approximately 27\u201329% above the rigid boundaries, reflecting the additional frame motion allowed by the isolation system \u2014 and are not ISO 20816-8 limits.<\/p>\n

          What are common causes of high vibration on reciprocating compressors?<\/h3>\n

          Common causes include worn crosshead or piston rod packing, loose foundation bolts, unbalanced opposing cylinders, degraded or leaking compressor valves, gas pulsation resonance in the piping system, misalignment between the compressor and driver, and crankshaft or bearing wear. The specific vibration frequency content (spectral analysis) helps distinguish between these root causes.<\/p>\n

          Is the Vibration Limits \u2014 Reciprocating Compressors tool free to use?<\/h3>\n

          Yes. The Vibration Limits \u2014 Reciprocating Compressors tool is a free browser-based engineering calculator (Free Engineering Tool #024) that implements ISO 20816-8 zone classification. It requires no registration, software installation, or payment. Engineers can input their measured vibration values and receive instant zone classification with operational recommendations.<\/p>","protected":false},"excerpt":{"rendered":"
