The problem

Pump-extraction failures mean half the pressure at the cup; manual simulation cannot reproduce real usage rhythm, and 5000 cycles cannot be pressed by hand. This bench runs both aging and linked modes with full performance-decay curves.

Capability

6 parallel stations (3+3 two layers), independent cylinder and program per station; 12V, 5000 aging cycles (60s work / 60s standby); period setting [(on x, off y) x m + rest z] x n, momentary or held press selectable; auto actions: fill (level-controlled), button press & gear select, stirring, drain valve, fan cooling (adjustable); cooling re-test every 100 cycles (fan 5min + HMI prompt); V/A/power per station live display; pressure & flow sensors per station with thresholds (pressure -15%, flow -20%, power +25%, no-flow 30s); 3-channel thermocouples per layer; PID bath 92-93C; sensors 4-20mA/RS485 MODBUS; Siemens PLC + HMI + 12V/60A supply; PC data management software optional.
