Core Materials and Formulas of Products

Some of our products utilize aerospace-grade 20CrMnTi alloy steel (GB/T 3077-2015 compliant) with HRC58-62 hardness and ≥1200MPa tensile strength, delivering superior wear resistance (43% lower wear rate vs. 42CrMo). Sealing materials employ FKM composite formula (PTFE+ graphene) or PU dynamic system (nano-SiO₂ + carbon fiber), with automated mixing ensuring ≥99.8% homogeneity. The lubrication system is optimized for various conditions: high-temperature (>150°C) uses PAO + 8-10% EP additives, while low-temperature (-50°C) adopts alkyl naphthalene + pour-point depressants, reducing -40°C startup torque by 62% and enhancing 150°C oxidation stability by 3.2x.

Key Parts Production Process

ritical components employ CNC precision machining & intelligent surface treatment: Gears are processed with 5-axis CNC machines (DIN 3962 AA grade) achieving tooth profile error ≤0.02mm (ISO 1328 compliant). Surface treatment combines deep carburizing (0.8-1.2mm hardened layer, HRC60±1) and mirror polishing (Ra≤0.2μm), tripling wear life. Pump bodies adopt low-pressure sand casting with hydrogen removal (H≤0.15ml/100g) and intelligent thermal control, maintaining porosity <0.3%. Precision boring (±0.005mm tolerance) and digital face grinding ensure dynamic gear-pump clearance 0.03-0.05mm, reducing leakage by 68%.

Assembly and Performance Optimization

Core assembly employs intelligent thermoforming & multi-stage sealing: Shaft-gear components achieve zero-clearance interference fit (IT4 grade) via induction heating with ±5℃ precision, combined with triple FKM seals (axial O-ring + radial step-ring) and servo press-fitting (±0.5% force control), ensuring leakage rate ≤0.01ml/min. Performance optimization includes dual-plane dynamic balancing (residual unbalance ≤0.5g·mm/kg) and extreme condition testing: At 4000rpm (ISO 1940 G2.5 compliant), vibration ≤1.8mm/s with 62dB(A) noise (DIN 45635 certified), reducing energy loss by 40% vs industry benchmarks.

Quality Testing and Certification

Our quality assurance combines comprehensive performance validation & authoritative certifications: 10-30MPa pressure-flow characteristic testing with multi-channel DAQ (1kHz sampling) maintains flow fluctuation ≤±1.5% (ISO 4400-2022 compliant). 500-hour accelerated endurance testing (80℃ oil + peak pressure shocks) achieves <2.8% efficiency decay, surpassing industry standards. Certified by TÜV Rheinland (EN ISO 13849-1 safety) and CE Machinery Directive, with SGS third-party reports (including HTHP test bench raw data), guaranteeing global compliance.
