What are the characteristics of the hydrogen compressor?

1. The working pressure range of the hydrogen compressor is large. Different pump types can be selected to obtain different pressure ranges, and the inlet air pressure and outlet air pressure can be adjusted accordingly. Can reach extremely high pressure, liquid 300 MPa, gas 90 MPa

2. The hydrogen compressor has a large flow range and can work smoothly for all kinds of pumps with only 1 kg air pressure. At this time, the minimum flow rate is obtained, and after setting the inlet air volume, different flow rates can be obtained.

3. The hydrogen compressor is easy to control, from simple manual control to fully automatic control, the requirements can be met.

4. The automatic restart of the hydrogen compressor, regardless of what causes the pressure drop of the pressure holding circuit, is automatically restarted to supplement the leakage pressure and keep the circulation pressure constant.

5. The operation of the hydrogen compressor is safe, gas-powered, without arcs and sparks, and can be used in dangerous situations.

6. The maximum energy saving of the hydrogen compressor can reach 70% because maintaining the pressure does not consume energy.

How does a hydrogen compressor work?

The structure of the hydrogen compressor is more complicated. The more important components are cast iron cylinder, cast iron cylinder liner, cast iron cylinder head, cast iron crankshaft, connecting rod, cross head (including cross head slide), packing, piston (including piston ring), oil wiper rings, stainless steel piston rods, stainless steel air valves, etc., in addition to some auxiliary equipment such as gas filters, buffers, lubricating oil lines, etc. Like other piston compressors, hydrogen compressors comprise three processes: suction, compression, and discharge. Driven by the engine, the crankshaft drives the cross head, the connecting rod of the piston and the piston to move back and forth in the cylinder, and the gas is finally discharged through the gas valve under the compression of the piston.

What are the applications of hydrogen compressors?

1. In the chlorine-alkali industry, the main function of the hydrogen compressor is to cool and clean the wet high temperature hydrogen from the electrolysis process, put it under pressure, and keep the pressure of the hydrogen system stable, to ensure safe and stable operation of the electrolyser.

2. At present, the enormous environmental pressure and the gradual depletion of traditional fossil fuel energy are causing all countries of the world to actively seek new clean energies. Hydrogen energy and hydrogen fuel cells have attracted increasing attention in countries around the world due to their good environmental performance, high energy conversion efficiency and certain economic efficiency. Improving hydrogen energy infrastructure is essential to drive the development of hydrogen energy. The hydrogen compressor is one of the three most important monomer equipment required for the construction of a hydrogen filling station.
