Orient DF reciprocating process-compressor platform — Shanghai Orient Compressor Manufacturing

Datasheet

Product overview

Power: Selected process-duty driver · Pressure: Gas duty and frame selection · Flow: Composition and volume basis required

Orient describes DF as an internally developed technical product platform for process reciprocating compressors. Its product page discusses eight piston-force classes and opposed-balanced arrangements including odd-numbered rows. The company profile separately states a portfolio gas-force range of 4–155 tonne-force. That is a gas-force portfolio description, not an offered model's combined rod load, compressor weight, motor rating or pressure envelope.

The DF component account describes a cast-iron frame with multiple supports, CNC machining for main-bearing alignment, a forged alloy-steel crankshaft with one crank per row and short-stroke construction, forged alloy-steel connecting rods and adjustable crosshead shoes. It specifically describes aluminum-magnesium alloy bearing material. The original frame photograph shows an example assembly; its exact frame size and rated duty are not identified. Obtain the selected frame's speed, stroke, rows, rod loads and drawings.

The manufacturer describes modular development and computer-based design, plus controlled tightening using torque or hydraulic tools. General comparisons of wear life, noise or energy use are not substituted for test values at the buyer's operating point. DF-HA has its own bearing and lubrication description, so confirm the offered materials rather than transferring the general DF description to every derivative.

Specify actual process gas, suction variation, discharge, capacity/reference conditions, operating modes, gas-side lubrication and permissible carryover/leakage. Request materials, packing and distance-piece arrangement, valve selection, driver/site derating, pulsation/vibration study boundary, utilities, controls, foundation loads, performance/mechanical tests and serviceable parts. The existing page retains the platform name without inventing a duty-specific model, flow, motor power or operating pressure.
