the working principle
1. Filtration stage
After the compressed air enters, it first strikes the baffle to produce a swirl, and large particles and liquid water are thrown to the water collection cup due to centrifugal force, and then the air is further purified through the filter element.
2, pressure reduction adjustment
Balanced state: The output pressure acts under the diaphragm and is balanced with the regulating spring force, and the spool maintains a stable opening.
Pressure fluctuation response:
Increased output pressure: the thrust on the diaphragm increases, the spring is compressed, and the spool is moved up to reduce the opening and limit the airflow.
Output pressure reduction: the spring pushes the diaphragm down, the spool opening increases, and the air supply increases.
Dynamic adjustment: Through the feedback mechanism to achieve automatic pressure stability, accuracy up to ±5%.
3. Typical work flow
Air intake (0.3-1.0MPa) → filtration (removing oil and water impurities) → decompression (adjusting to 0.1-0.7MPa) → stable output.
Core functions
Clean air: Protect precision pneumatic components (such as solenoid valves, cylinders) from contamination.
Stabilized output: eliminate the influence of air source pressure fluctuation on the actuator to ensure consistency of action.
Safety protection: Overpressure is prevented by overflow design, and some models integrate pressure switches to achieve interlock control.
