The Nitrogen-Hydrogen circulating
compressor is of reciprocation, double action, balanced
opposed type with 2-throws single stage. In the
middle-sige packaging equipment for producing synthetic
ammonia, the unreacted mixture of nitrogen and hydrogen
will be boosted in the compressor and will return
to the ammonia converter to continue synthetic reaction.
The compressor features high working pressure,
small compression rate. In practice of several decades.
Dalong circulators have succeeded in solving the
problems of vulnerable parts' life and pipeline-vibration,
gas-discharge will be oil-free according to the
process requirement. So it is in users' favour.
