The product is driven by an explosion-proof motor in the hydraulic drive system, which drives the hydraulic oil pump to actuate the piston in the hydrogen pressurization system, compressing the hydrogen gas.
The hydrogen pressurization system adopts single-stage compression. The pressurization system integrates a cooling system and has a compact structure.
A. Product Highlights-Oil isolation technology
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
Compared with traditional methods, liquid-driven hydrogen compressors have the following advantages:
(1) The equipment runs at a low speed and has little vibration;
(2) Multiple protection devices make operation safer;
(3) The structure is classical and of reasonable design;
(4) The exhaust volume can be adjusted to protect the environment;
(5) One machine can be used for multiple purposes, such as filling the car, emptying the tank, etc., to meet the various needs of users;
(6) Simple maintenance and low overall use cost;
(7) Frequent start and stop are suitable for real working conditions;
(8) Oil-free lubrication is safe and reliable;
(9) The piston seal has a long service life and no pollution

The current displacement of our liquid drive compressor products covers the filling needs of two displacements: 500kg and 1000kg.
The liquid-driven hydrogen compressor skid uses a hydraulic system to drive the gas booster cylinder to pressurize the low-pressure hydrogen to fill Pressure, system start/stop and output pressure control PLC The system is integrated into the compressor electrical control cabinet. It can be connected with the user's electrical control system to achieve automatic control.
(1) Pressurization system
The booster system is the core component of the compressor, which consists of the cylinder, oil cylinder, isolation chamber, purge pipeline, hydrogen The low-pressure gas source enters the booster system and drives the hydraulic system to The hydraulic cylinder drives the gas cylinder to reciprocate, and the difference in area between the two is used to pressurize the hydrogen.
