Lianhe DWF natural-gas transfer — named duty and package scope — Bengbu Lianhe Compressor

Datasheet

Product overview

Power: DWF-5.4:offered motor to confirm · Pressure: DWF-5.4:0.17–0.345 →2.1 MPa · Flow: DWF-5.4:5.4 m³/min;reference to agree

Lianhe names DWF-5.4/(1.7-3.45)-21 for natural-gas pressure boosting and transfer. Its header publishes 5.4 m³/min, 0.17–0.345 MPa inlet and 2.1 MPa discharge. The flow reference is not fully stated, and a motor or dimensional value for this named header is not supplied. Do not assign a different family-table row's motor or envelope to DWF-5.4.

The manufacturer's description calls this gas compression non-lubricated and lists compressor, motor, coupling, flywheel, piping, cooling, electrical and auxiliary equipment. Cooling may be water, air or mixed; package forms include fixed, mobile, skid and acoustic enclosure by requirement. Define the actual gas-path lubrication boundary, package drawing and supplied auxiliaries. This wording does not make every bearing or drive mechanism lubricant-free.

A separate table row DW-4.9/(1.5-2.5)-22 lists 700 Nm³/h, 0.15–0.25 MPa inlet, 2.2 MPa discharge, 110 kW and 740 rpm, water cooling, 3800 × 2700 × 1800 mm and approximately 6000 kg. Another separate VWF-1.65/(25-35)-50 row gives 2500 Nm³/h, 2.5–3.5 MPa inlet, 5.0 MPa discharge, 90 kW and air cooling. These are family selection examples, not specifications of the pictured DWF header machine.

The page describes alarms/stops for low oil pressure, low water pressure, high temperature, low inlet pressure and high discharge pressure, with remote display/control by requirement. Obtain offered instruments, setpoints, interfaces and shutdown responsibility in the actual control schedule. Generic multi-industry application sentences do not establish food-contact, instrument-air or other gas suitability.

Provide composition, temperature, complete suction envelope, flow basis, required receiving pressure, liquid/contaminant conditions and duty cycle. Agree materials, sealing, purity/carryover, conditioning, vents and cooling utilities. Obtain offered performance, package input, P&ID, electrical/control and installation/foundation drawings, maintenance clearances, manuals and factory/acceptance tests. Specify commissioning, training, warranty scope and destination support. The complete original machine photograph is the manufacturer's non-standard natural-gas example, not every family configuration.
