Key design considerations for cyclic hydrogen compressors
Thread Content
Dear marine industry professionals: What are the key design considerations for reciprocating piston-type hydrogen cycle compressors?
Special attention should be paid to the reverse angle of the cyclohydrogen compressor
Reply to 2# spoole: Could you explain in more detail?
The hydrogen circulator used in our factory is a 2D5.5/3.4-240-26 model
Is the model correct? What’s the power? Let’s talk about it in detail as well.
Reply to 5# lucy751b: Model: 2DZ5.5A-3.4/240-260; Power: 200KW; The medium is 99.99% pure hydrogen. Our machine is experiencing severe leakage of filler gas at the moment, and that issue hasn’t been resolved yet.
Oh, with such high pressure, the filler does tend to leak air. Which company makes the filler?
The design of hydrogen compressors must take into account the flammability and explosiveness of the medium; a dual-chamber design is required, and the chambers must be purged and sealed with nitrogen. If there are small amounts of other corrosive substances in the medium, hydrogen purging or sealing for the gaskets is also necessary.
Reply to 8# hanjun512: Could you explain it in more detail? It would be best to provide a structural diagram or some kind of blueprint.
Hydrogen will definitely leak from the filler area. To prevent this gas from entering the crankcase, a dual-chamber design serves as a protective measure; moreover, the hydrogen that leaks into these chambers is promptly removed using nitrogen, further preventing backflow of hydrogen and thus ensuring the safety of the unit’s operation. You can check API618; it contains information on hydrogen compressors.
That’s what everyone says; whether it can actually achieve the desired results will only be determined by time. Technology is known; the key is experience.
