Some discussions on reciprocating compressors
Thread Content
1. Fuselage vibration: Meets the requirements of GB/T7777-2003 standard (Is 18 mm/s too high?) ) 2. Lifespan of vulnerable components: Cylinder liner: 24,000 hours; Piston rod: 24,000 hours. Is it too low?
1. We are* used to requiring that the aircraft body vibration be ≤11.2 mm/s; generally, an alarm is triggered at ≥8 mm/s and the system shuts down at ≥12 mm/s (first-tier domestic manufacturers can basically achieve this)； 2. 24,000 hours is a considerable amount; it’s the international standard, but we *prefer* a requirement of >30,000 hours.
