Hangyang nitrogen reciprocating compressor duty selections — Hangzhou Hangyang Compressor

Datasheet

Product overview

Power: 400 / 185 kW, distinct nitrogen duties · Pressure: 0.108 → 3 or 0.105 → 9.5 MPa; inlet absolute · Flow: 2160 / 660 m³/h, source reference to confirm

Hangyang's nitrogen table gives model-specific flow, inlet/outlet states, speed, motor and cooling-water requirements. ZW-36/30 is listed at 2,160 m³/h, 0.108 MPa(A) inlet and 34°C, with 3 MPa outlet and 40°C. It runs at 593 rpm with a Y5001-10 motor rated 400 kW / 6,000 V and a total water figure of 45 t/h. The source labels this flow m³/h without N, and gives outlet pressure as MPa without an absolute/gauge indication. Request these reference conditions in the technical offer.

Its arrangement table gives vertical construction, three rows and three stages, with installation dimensions of 7,500 × 5,000 × 3,600 mm and 20,000 kg mass. ZW-11/95 is a separate higher-pressure duty: 660 m³/h, 0.105 MPa(A) inlet at 35°C, 9.5 MPa outlet at 40°C, 590 rpm and a Y355L2-10P motor rated 185 kW / 380 V. Its water figure is 12.5 t/h. That machine is vertical, three rows and four stages, at 3,800 × 3,200 × 3,000 mm and 9,776 kg.

Neither duty can be selected from discharge pressure alone. Define nitrogen purity and impurities, source pressure over operation, inlet temperature, volume reference and the receiving-system requirement. Review cooling supply and return conditions, power and starting method, piping/support interfaces, sealing and vent scope, and current arrangement drawings with maintenance space. Ask for the actual project's pulsation/vibration analysis and performance/acceptance records. The nitrogen-family photograph illustrates the manufacturer catalog; it does not prove the depicted assembly is either named model.
