Selection of lubricating oil pump for reciprocating compressors? Should I choose a dual electric pump or one shaft head with one electric pump?
Thread Content
The medium is hydrogen-rich and has a low molecular weight; therefore, shaft-mounted pumps are used as the primary option with electric pumps serving as a supplement, or two electric pumps – one as the primary pump and the other as a supplement. What are the advantages and disadvantages of these two approaches? What is the basis?
Regarding this topic, it depends on the importance of this device in the production process; please clarify.
Currently, most hydrogen compressors are equipped with shaft-mounted pumps. Then the oil battle is paired with dual pumps. Fear that the oil pump will lose power while the compressor is still running. If it is a pump without a shaft head, emergency measures must be taken in case of a sudden loss of lubricating oil pressure to ensure safe operation
