1.Liquid-Driven Compressor

■ The compressor features a unique design where the oil cylinder is distinct from the gas cylinder. Utilizing oil-free lubrication for the piston prevents contamination of the compressed medium during the compression process. Employing a multi-seal system for the gas and oil chambers, alongside specialized oil-gas isolation chambers, ensures complete separation of oil and gas. This innovative oil-gas isolation chamber structure guarantees that hydrogen remains uncontaminated even in the event of damage to the sealing ring, thus maintaining gas purity at the outlet. This compressor operates without components like crankshafts and connecting rods, eliminating the need for a lubrication system.

■ Hydraulic piston compressors exhibit low linear speed and switching frequency, resulting in extended service life for seals and valves compared to other reciprocating compressors. Their extremely low reciprocating frequency and piston linear speed contribute to prolonged durability.

■ The gas cylinder piston is propelled by a hydraulic system, minimizing vibrations and noise. The motor drives the high-pressure oil pump, subsequently powering the compression cylinder under stable loading and operating conditions, thereby extending the service life of both the compression cylinder and motor.
