Advantages and Characteristics
Dual function integrated design:
Energy storage end: using high-strength alloy cylinder (such as 42CrMo)+rubber airbag/piston seal, gas leakage rate ≤ 0.5%/year, can stably store energy in an environment of -40 ℃~+80 ℃;
Execution end: The surface of the piston rod is plated with hard chromium (20-30 μ m), combined with a wear-resistant guide sleeve, to achieve synchronous driving and energy release, reducing the number of system components.
Ultra long energy storage retention capacity:
The sealing system adopts a polyurethane+metal skeleton composite structure, combined with phosphating treatment on the inner wall of the cylinder. During static pressure holding, the pressure attenuation is ≤ 1%/24 hours, which can meet the emergency power needs of equipment shutdown within 72 hours .
High environmental adaptability:
Anti vibration: able to withstand 50Hz, 50g acceleration vibration, suitable for bumpy working conditions of construction machinery;
Resistant to medium pollution: Equipped with high-precision filters, extending the lifespan of seals to 8-10 years.
