Expansion Refrigeration Process

The DTRO membrane module includes a pressure vessel, a hydraulic disc, and a diaphragm sandwiched between every two discs. This special structure forms an open flow channel between the valve flap and the diaphragm.

The machine bed, column, saddle, worktable, and headstock are made of high-strength Meehanite cast iron molded with resin sand and a reasonable reinforcement structure. The machine tool adopts three-way cast iron hard guide rail, which has good rigidity and precision retention. Using disc cam type tool magazine, tool change time is short, and accurate and reliable. The main shaft adopts the well-known brand main shaft assembly, which has high precision and reliable operation. The CNC system and the servo drive adopt a complete set of systems with foreign brands, with a good working interface. Stable and reliable operation. It adopts timing and quantitative automatic lubrication device, which has low abrasion and is suitable for long-time operation requirements.
