Aiming at the core challenges faced by 90 MPa diaphragm hydrogen compressors in high-pressure hydrogen energy refueling scenarios,such as equipment vibration,hydrogen corrosion,diaphragm fatigue,and seal failure,this paper constructs an integrated solution encompassing"design-materials-processes-safety-industrialization"through gas-solid-liquid multi-physical field coupling simulations,anti-hydrogen embrittlement structural innovations,oil-gas synergistic control technologies,and composite diaphragm cavity profile designs.The study optimizes a two-column symmetrically balanced main machine structure,incorporating an integrated cylinder head with an embedded valve distribution disc,an integrated hard-sealed diaphragm,and a parabolic-circular arc composite diaphragm cavity profile.Additionally,it develops an integrated high-low pressure oil pump drive mechanism,a wave spring gas valve,and a highly reliable connecting rod bushing.Performance test results indicate that the overall machine vibration is≤8 mm s,diaphragm lifespan is increased to over 8000 hours,connecting rod bushing lifespan exceeds 50,000 hours,and the exhaust pressure is stably maintained at 90 MPa(with an exhaust volume of 500 m 3 h),achieving a 95%localization rate.This research provides crucial technical support for the localization and large-scale application of high-pressure hydrogen energy equipment,with the equipment performance reaching international advanced levels.
