1. Liquid driven compressor

■ For the compressor, the oil cylinder is separated from the gas cylinder, of which the oil-free lubrication is used for the piston, preventing the compressed medium from being contaminated during the compression process. Multi-seal is used for the gas and oil chambers in a special form of oil-gas isolation chambers to completely separate oil and gas. This structure of oil-gas isolation chambers ensures that hydrogen will not be exposed to oil even in case of any damage to the sealing ring, which further maintains the gas purity at the outlet. No lubrication system is needed for this compressor without components such as crankshafts and connecting rods.

 

■ Hydraulic piston compressors have a low linear speed and switching frequency. In contrast to other types of reciprocating compressors, hydraulic piston compressors have extremely low reciprocating frequency and piston linear speed, ensuring prolonged service life the sealing and valves.

 

■ The gas cylinder piston of the compressor is driven by a hydraulic system with less vibrations and low noise, in which the motor drives the high-pressure oil pump and then the compression cylinder under stable loading and operating conditions, extending the service life of the compression cylinder and motor.

At the same time, for critical parts such as electrodes and membranes, we have independently designed and developed the only testing platform in the industry, considering the current absence of relevant testing standards and significant fluctuations in experimental results of conventional testing methods. We have carried out a large number of research and development experiments and established the details of system testing methods to solve the problems of complex testing and significant fluctuations in results of critical components such as electrodes and membranes, achieving the multi-dimensional assessment of the performance of critical core components and effectively ensuring their advancement and stability.
