4. Maintenance Strategy

4.1 Routine Inspection Points

Pressure monitoring: Record shell/tube side pressure gauge readings each shift; initiate cleaning if differential exceeds 0.1MPa

Temperature monitoring: Maintain 5-8℃ cooling water inlet/outlet difference; check flow control valves if abnormal

Leak detection: Use infrared thermography to scan tube connections; investigate if temperature difference >3℃

4.2 Scheduled Maintenance

Interval Maintenance Task Technical Requirement Quarterly Finned tube cleaning Compressed air blow pressure ≤0.6MPa Semi-annually Cooling water quality test Total hardness ≤150ppm, pH 6.5-8.5 Annually Seal replacement Fluororubber material (-40℃~+150℃) 3 years Tubing inspection Eddy current detects 0.1mm defects

4.3 Troubleshooting Guide

Symptom 1: Abnormal outlet temperature increase

Diagnosis:

Check cooling water flow (should be ≥15m³/h)

Measure finned tube cleanliness (clean if dust >2mm)

Verify temperature valve opening (normal range 40-80%)

Symptom 2: Tube leakage

Solution:

Minor leaks: Use J-B Weld cold weld sealant

Major leaks: Replace single tube (requires hydraulic tube expander)
