Reciprocating refrigeration compressor site acceptance test, performance witness and handover document checklist

Reciprocating refrigeration compressor site acceptance test, performance witness and handover document checklist

Site acceptance test verifies compressor performance, safety interlock and control function after installation or overhaul; only qualified acceptance allows formal handover to end user. Acceptance test includes 4-hour continuous rated load operation; key parameters including capacity, power, vibration, temperature shall all stay within factory specification range. Xiteliduo reciprocating compressor acceptance package includes performance curve report, sensor calibration certificate, safety interlock test log and spare parts list. Small 4-cyl reciprocating refrigeration compressor acceptance focuses on basic capacity and safety protection; most complex interlock functions are optional for compact units. Medium 4-cyl reciprocating refrigeration compressor acceptance shall include unloading mechanism step test; verify every capacity stage can switch smoothly without abnormal vibration. Large 4-cyl reciprocating refrigeration compressor acceptance requires oil sample analysis during rated load test; metal particle content must stay below warning threshold. Large 6-cyl reciprocating refrigeration compressor acceptance shall conduct individual cylinder performance test; each cylinder’s discharge temperature and pressure shall be recorded. Many projects skip full load acceptance test and directly hand over unit. Skipping witness test raises hidden fault discovery delay risk by 55%. Single-unit two-stage refrigeration compressor acceptance shall test low-stage and high-stage separately, then run combined full load test to verify interstage pressure stability. Cascade unit high-stage reciprocating refrigeration compressor acceptance must coordinate with low-stage commissioning; high-stage performance cannot be verified independently without low-stage operation.

FAQ

Q1: What is the required continuous running duration during reciprocating compressor site acceptance test? A1: 4-hour continuous operation under rated load condition. Q2: What documents are included in Xiteliduo compressor acceptance handover package? A2: Performance curve, sensor calibration certificate, interlock test log and spare parts list. Q3: What is the core acceptance content for small 4-cyl reciprocating refrigeration compressor? A3: Verify basic cooling capacity and safety protection functions. Q4: What test item must be performed for medium 4-cyl compressor unloading mechanism acceptance? A4: Step test for every capacity stage to confirm smooth switching. Q5: What oil analysis requirement exists for large 4-cyl compressor acceptance test? A5: Oil sample taken during rated load run, metal particles must remain below warning level. Q6: What risk will happen if full load witness acceptance test is omitted during project handover? A6: Hidden faults will be discovered late, with risk increased by 55%. Q7: Why cannot cascade high-stage compressor performance be tested independently? A7: High-stage operation relies on low-stage system running to maintain working condition.
