Low temperature liquid pump: The flow rate of the low temperature liquid oxygen pump has reached 60,000 Nm3 / h and the pressure reached 8.0 MPaG. According to the API standard, it has completed a 72-hour continuous life test of liquid nitrogen. The pump can fully meet the 100,000 in terms of flow and pressure. The above requirements for dual-use and one-liquid preparation of liquid oxygen pumps in the air separation process.
