Embodiment 1
[0045] Such as Figure 1-2 As shown, a guide vane control circuit stroke detection and debugging method with a pressure distribution valve includes the following steps:
[0046] S1: Design the guide vane control block diagram according to the mechanical equipment structure of the pumped storage unit, and use the two-stage amplification method of the electro-hydraulic converter and the pressure distribution valve to drive the guide vane servomotor to move through the oil pressure; therefore, the general design in the guide vane control circuit Cascaded way;
[0047] S2: Determine the stroke detection method of the guide vane servomotor and the main pressure distribution valve;
[0048] S3: making and installing a linkage mechanism and a sensor, the sensor is used to detect the stroke of the main pressure distribution valve and the guide vane, and the linkage mechanism is used to convert the stroke of the main pressure distribution valve and the guide vane into the measuring st...
