IOT DW-1.94/(1.5~2)-(3~3.2) natural-gas compressor — defined boosting duty — Bengbu IOT Compressor

Datasheet

Product overview

Power: 11 kW motor · Pressure: 0.15–0.20→0.30–0.32 MPa · Flow: 250–270 Nm³/h;normal reference to agree

IOT's natural-gas table gives DW-1.94/(1.5~2)-(3~3.2), normal capacity 250–270 Nm³/h, suction 0.15–0.20 MPa and delivery 0.30–0.32 MPa. Treat these as the offered boosting reference, distinct from general natural-gas/CNG applications. Pressure convention and normal-volume reference are not fully defined by the page.

The D-type is one-stage, two-cylinder, direct-driven and water-cooled. It lists 720 rpm compressor speed, 11 kW motor, 380 V and a 30–50 Hz variable-frequency entry. The frequency interval is not a tested flow/turndown map. Approximate envelope and weight are 2000 × 1600 × 1500 mm and 980 kg; the inlet temperature entry is ≤40°C.

Provide actual gas analysis and variation, inlet pressure and temperature envelope, condensate/contaminants, receiving pressure, normal base/peak flow and operating cycle. Obtain the duty curve for those conditions rather than extrapolating capacity from frequency or assuming the maximum pressure and flow combine under every inlet state. Request actual cooling-water demand and inlet/outlet conditions.

The source explicitly separates non-lubricated cylinders and packing from pressure-lubricated crankshaft, connecting rod and crosshead. Define seals/materials, carryover/purity and gas-path scope. Its IP55/DIIBT4 motor wording requires offered documents and destination suitability checks; broad component-brand references do not establish the bill of materials for all packages.

The historical CN114251248B publication names the company for a connection/protection design, but does not identify this DW row as a tested implementation. Ask for the supplied P&ID, separators/filters/instruments, control and protective interfaces, installation/removal drawing and actual acceptance records. Agree manuals, spares, commissioning and order-specific warranty/support. Original catalogue image retained complete; no current customer installation is inferred.
