Uncontrolled vibration transfers stress to piping and foundations; Xiteliduo specifies isolator selection and installation limits for piston compressors. Cold storage refrigeration compressor generates periodic vibration from reciprocating piston motion; rigid mounting transmits vibration to pipework and building structure. Semi‑hermetic piston compressor rubber isolation pads are suitable for small units; spring isolators are required for compressors above 15 kW rated power. Refrigeration compressor for food cold room installed on upper floors must control vibration to avoid disturbing adjacent production and storage areas. R404A piston refrigeration compressor isolators are selected with static deflection of 10–15 mm to shift natural frequency away from piston excitation frequency. Low temperature cold storage compressor and 2‑stage piston refrigeration compressor have larger mass and pulsation, requiring heavier‑duty spring isolation sets. Chinese refrigeration compressor manufacturer vibration test data shows properly isolated units reduce piping vibration amplitude by 70–82%. Semi‑hermetic compressor price comparison seldom includes certified vibration isolators; many installers mount compressors directly on rigid steel base frames. Refrigeration compressor fault troubleshooting for cracked discharge pipes and broken pressure taps often traces back to inadequate vibration isolation. Cold chain refrigeration unit compressor skids are pre‑fitted with matched isolators, with flexible metal hoses on suction and discharge connections. Flexible joints must be installed straight, without offset or angular bending; misalignment creates extra stress and shortens hose service life. Xiteliduo warns that anchor bolts must not lock down isolators; isolators must float freely to absorb cyclic vibration energy. Isolator inspection every 12 months checks for rubber aging, spring fatigue and settling, re‑leveling the base frame as required. If vibration still persists after isolation, suction and discharge piping need additional pipe hangers with spring supports to break vibration transmission paths.
FAQ
What isolator type is recommended for piston compressors above 15 kW? Spring isolators are required for larger compressors over 15 kW.
What static deflection range is used for piston compressor isolators? 10–15 mm static deflection to detune vibration resonance.
How much vibration reduction can qualified isolators achieve? Proper isolation cuts piping vibration amplitude by 70% to 82%.
What installation mistake defeats vibration isolation function? Over‑tight anchor bolts locking the isolator and eliminating float.
What accessory separates compressor vibration from fixed piping? Flexible metal hose joints on suction and discharge lines.
What is the recommended annual inspection item for isolators? Check rubber aging, spring fatigue and base frame level condition.
