One week per pump curve by hand? 6-station pump bench scans PWM duty points automatically and plots H-Q curves in one click

The problem

BLDC pumps with PWM speed control need a full curve per sample; manual point-by-point testing takes an hour per pump and five endurance channels cannot be logged by hand for months. This bench scans duty points automatically and merges up to 10 pumps into one Excel report.

Capability

6 independent water circuits: 1 performance + 5 endurance, for large/small flow pumps; test objects: household booster / submersible / drainage pumps up to 200W and 10A; head 0-50m (0-500kPa), pressure sensor class 0.1; flow 5-40L/min, performance circuit accuracy plus/minus 0.5 percent, endurance circuits plus/minus 1 percent; program-controlled DC supply DC0-300V/10A with communication, plus DC0-120V/2KW; PWM output capture DC0-300V with fault and speed signal detection; stepper motor adjusts outlet valve opening (5 percent steps) for automatic multi-point scanning (at least 10 points); curves auto-generated to Excel, up to 10 pumps per sheet, screen readings match gauges; program-based OK/NG judgement against set flow/head/power/efficiency limits; medium tank 0.4m3, temperature 25-85C settable; power-fail data protection; Mitsubishi FX3U PLC + 10-inch Weintek HMI + 15-inch industrial PC + ForceControl software; over-temperature / over-current protection; frame approx. 1550x880x1730mm, 220V/50Hz, braked casters.
