(A) Set screw (B) Push rod 1 (C) Push rod 2 1. Adjustment of the aneroid compensator itself and the adjustment after mounting the governor (1)Set the speed of the pump to N1 r/min and fix the control lever at the full set position. (2)Screw in (A) to obtain the performance shown in the graph (to obtain L1). (3)Adjust the (D) spacer so that dimension L2 is obtained. (4)As there is hysterisis, measure when the absolute pressure drops. (5)Hysterisis must not exceed rack position = h1.
