(A) Housing (B) Snap ring (C) adjusting screw (D) Set screw (E): Push rod (F) Spacer 1. Adjustment of the aneroid compensator (1)Adjust with the (D) set screw so that the clearance between the (A) housing and (B) snap ring is L1. (2)Select the push rod (E) so that the distance from the end surface of the (F) spacer becomes L2. (3)(C) Turn the screw to adjust the beginning of aneroid compensator operation. 2. Adjustment when 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)Adjust using screw C to obtain the performance shown in the graph above. (3)After final adjustment, confirm that the gap between housing (A) and snapring (B) is L3.
