Working principle of the hydrogen compressor
Hydrogen compressor structure is more complex, the more important components are cast iron cylinder, cast iron cylinder sleeve, cast iron cylinder head, cast iron crankshaft, connecting rod, crosshead (including crosshead slide), filler, piston (including piston ring), scraping oil ring, stainless steel piston connecting rod, stainless steel gas valve, etc., in addition to some auxiliary equipment, such as gas filter, buffer, lubricating oil pipeline, etc. Like other reciprocating compressors, the hydrogen compressor comprises three processes: suction, compression, and exhaust.Under the motor drive, the crankshaft drives the crosshead, the piston connecting rod and the piston back and forth in the cylinder, and the gas is finally discharged through the air valve under the piston compression.
