Product Description
Hydrogen Gas Compressor
The hydrogen gas compressor is primarily utilized in hydro-generation stations to pressurize low-pressure hydrogen to a specified level and store it in hydrogen storage containers at hydrogen refueling stations or directly fill vehicle-mounted cylinders to meet customer demand for hydrogen gas refills.
Compared with the oil-isolating sealing structure of competitors, the LexFlow brand's unique cylinder seal + isolation chamber oil-isolating structure implements double isolation and protection of oil. The oil film part of the piston rod is isolated from the cylinder, which prevents oil from entering the cylinder and contaminating the medium at the molecular level. Build a "pollution-free" hydrogen refueling station.
B. High-efficiency spiral liquid cooling technology - calmly cope with various working conditions
The compressor cylinder adopts a 360-degree spiral cooling structure with no dead ends. The heat transfer efficiency is improved through structural optimization and the cooling capacity of the cooling medium is fully utilized. The exhaust temperature is 10°C lower than the exhaust temperature of conventional structures.
Key technical features
A. Specialized structural design and processing technology to enhance service life
B. Hydraulic system with simple control and low failure rate
C. Simple structure, minimal parts, and convenient maintenance, enabling replacement of a group of senior pistons within 30 minutes
D. Special construction design for improved heat conduction and enhanced volume efficiency of the compressor
E. Each product undergoes pressure, temperature, displacement, leakage, and other performance testing using helium gas before delivery.
The current displacement of our liquid drive compressor products covers the filling needs of two displacements: 500kg and 1000kg.
