Product overview
Power: Selected L rows: 110 /132 kW · Pressure: Named inlet rows→25 MPa family delivery · Flow: Selected duties: 540 /800 /700 /1500 Nm³/h
Tongda presents L-type natural-gas compression for CNG standard stations. The page summary gives 0.20–5 MPa inlet, 75–132 kW, 25 MPa delivery and 500–1500 Nm³/h. Match the offered model's duty rather than treating maximum flow, minimum motor rating and all inlet states as a combined selection.
The original model table gives L-3.3/2-250 at 0.20 MPa inlet, 132 kW, 540 Nm³/h, 590 rpm, 200 mm stroke and four stages. L-1.3/10-250 gives 1.00 MPa inlet, 132 kW and 800 Nm³/h, 590 rpm/200 mm/four stages. Equal motor ratings under different inlet conditions are not evidence of an efficiency ranking.
L-1/12-250 gives 1.20 MPa inlet, 110 kW, 700 Nm³/h, 590 rpm, 200 mm stroke and three stages. L-0.66/40-250 gives 4.00 MPa, 132 kW, 1500 Nm³/h, 590 rpm, 200 mm stroke and two stages. Delivery is the page's 25 MPa family duty; pressure convention and normal-flow reference need agreement. Do not infer stage count or flow from an unrelated suffix.
For a standard station, supply pipeline pressure/temperature variation, gas analysis, normal base/peak requirement, filling profile and utilities. Specify actual gas treatment, dehydration, storage sequencing, dispenser/metering and controls. Obtain offered cooling/lubrication, gas-path materials/seals and protective interfaces, rather than borrowing XD's circuit or controls.
Compare compressor and total package/station input at the same duty. Request performance curves, P&ID, installation/lifting/maintenance drawing, actual applicable documents, factory/site tests, manuals and wear parts. Agree commissioning, warranty and destination support. The original L-page machine image is retained complete as a family reference; a station layout and accessory list require an offered drawing.
