Oil and Water Constant Pressure System

Oil and Water Constant Pressure System transfers the pressure generated in the oil circuit to the water through a transparent oil–water chamber, delivering clean and bubble-free flow to the triaxial cell. Its compact, bench-top construction integrates a pressure control panel, fine-adjust regulators/valves, safety relief system, and quick-connect couplings into a single body. The system provides a continuously variable pressure and stepless control within standard laboratory ranges. A digital pressure gauge allows smooth adjustment to the target pressure; pressure increase or decrease is operated via the front-panel control lever. A high-visibility reservoir enables easy monitoring of the water level and trapped air; the de-airing line allows rapid removal of air from the circuit. Adequate water capacity is provided for long-duration tests. The chemically compatible hoses are resistant to water and laboratory fluids. Quick-release fittings allow direct integration with the triaxial cell, the volume-change device, and pore-water pressure transducers.
