Shenjiang W-1/7 piston machines — identify the complete receiver package — Changzhou Shenjiang Compressor

Datasheet

Product overview

Power: Offered motor rating required · Pressure: Actual model pressure sheet required · Flow: Delivered flow/test basis required

The official W-1/7 page identifies a piston air compressor and shows receiver-mounted units with motor drive and a reciprocating head. Its published group photograph is dated 17 November 2021. Use W-1/7 as the page's model identifier, not as a substitute for an independently read flow, pressure or motor rating: a numerical duty table is not supplied on this page.

The company's piston description explains motor-driven crank motion, reciprocating pistons and intake/discharge valves. Its wording labels an intake step as compression; the functions should instead be distinguished as drawing in air, compressing it and discharging it. The actual cylinder/stage and lubrication arrangement of the offered model must be confirmed, rather than copied from a generic working-principle paragraph.

Ask for motor power, voltage/phase/frequency, delivered flow with reference/test conditions, working/discharge pressure, permitted running cycle and load/unload or start/stop behavior. Agree receiver volume/design pressure, pressure-switch settings, relief arrangement and outlet connection. The visible receiver or a sticker does not establish a current certification, oil-free output or continuous-duty guarantee.

For workshop selection, provide the actual tool/process pressure, consumption during use, simultaneous tools, duty hours and hose/network losses. Check supply and starting capability, operating ventilation, guarding and service access. Request drainage and lubricant/maintenance instructions, filter or other treatment scope, wear parts and model-specific dimensions/mass and handling information.

Confirm the complete supplied boundary: head, motor/drive, guards, receiver, controls and auxiliaries, versus a head-only replacement. The manufacturer separately lists compressor heads and cast/machined parts; a similar-looking head is not automatically compatible with an existing assembly. Agree offered performance and delivery documents, packaging, destination pressure-equipment requirements, warranty and acceptance terms. The original photograph is a group view supplied by the manufacturer, not a measured drawing of each machine.
