Oil-free hydrogen reciprocating compressors — Anshan Libang Compressor

Datasheet

Product overview

Power: 3 / 7.5 / 18.5 kW, selected model rows · Pressure: Selected rows: 0.05 MPa inlet; 1.0 MPa outlet · Flow: 10 / 30 / 90 m³/h, selected rows; confirm basis

Libang's hydrogen family uses oil-free gas-side reciprocating compression with self-lubricating sealing and guiding components. The manufacturer describes single- or multistage and different cylinder arrangements, with air or water cooling selected for the duty. Its hydrogen page names hydrogen-production systems and process circulation or reaction applications and gives a family suction envelope of 0–0.6 MPa(G) and discharge up to 5 MPa(G). Select from an actual confirmed configuration; the envelope is not a rating for every model.

The original model table labels volumetric flow in m³/h. VWZ-10/0.5-10 is listed at 10 m³/h, 0.05 MPa inlet, 1.0 MPa outlet and 3 kW, with 1,100 × 1,000 × 1,100 mm dimensions and 300 kg mass. VWZ-30/0.5-10 gives 30 m³/h at the same table pressure pair and 7.5 kW. SWZ-90/0.5-10 gives 90 m³/h and 18.5 kW, with 1,250 × 1,700 × 1,200 mm dimensions and 485 kg. Request the flow reference conditions; this table must not silently be relabeled as the nitrogen table's Nm³/h.

Specify the actual hydrogen concentration, impurities, inlet temperature and pressure variation, required delivery, process connection and installation environment. Agree the gas-side materials, sealing/leakage acceptance, applicable area/equipment protection documentation, controls, monitoring and qualified commissioning responsibilities. The controller's high-temperature and pressure-protection functions and configurable remote controls should be defined for the offered package. A component marking in a catalog photograph does not establish the complete assembly's current approval scope.
