N:Pump speed (r/min) R:Rack position (mm) Adjusting shim A Guide screw B (c) Nut (d) Nut (e) nut Torque control spring adjustment method for model responding to speed droop [Advice] Confirm that adjusting shim (A) thickness t = 1.3~1.5 mm is assembled before beginning adjustment. (1)Temporary idle lever position setting 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083). (2)Idling spring adjustment 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083). (3)Governor spring setting adjustment 1. Temporarily fix so that the governor shaft's guide screw B protrudes L2 (18 mm) from the end of the governor. 2. Set the control lever where it contacts the idle stopper bolt. 3. Increase the speed to Nh2+100 r/min or more. 4. Adjust using the two nuts C and D so that L1 = 0.3+0.5 mm and fix temporarily. 5. Adjust the protrusion L2 of the guide screw (B) so that the rack position at Nh1 is Rh1 and at Nh2 is Rh2. Then fix using the nut (E). 6. Further increase the speed and readjust the two nuts (C) and (D) so that there is no change in L1 until Nf+50 r/min. Then fix temporarily. [Advice] When L1 becomes smaller while speed is increasing to Nf+50 r/min, decrease speed by Nh2+100 r/min. Adjust so that L1 is even smaller, then again increase speed to Nf+50 r/min and confirm that L1 does not change. (4)Full load position setting 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083). (5)Torque control spring adjustment 1. Set the control lever so that it contacts the full speed stopper bolt. 2. At the specified speed Nf, adjust using the full speed stopper bolt so that governing begins, then fix temporarily. 3. Increase the speed and adjust using the two nuts (C) and (D) so that the rack position Rg can be obtained at the specified speed Ng. Fix temporarily. 4. Decrease the speed and confirm the governing point (the beginning of governing point) at the specified speed Nf. 5. Set the speed at Nf-50 r/min. 6. Measure the torque control stroke (L1) and adjust to the specified stroke (L1) using the shim (A). 7. After completing shim adjustment, repeat the above adjustment using the two nuts. 8. After confirming the specifications Nf and Ng, fix the two nuts (C) and (D). 9. In this condition, increase the speed and confirm that R = 0 can be obtained. (6)Full speed lever position setting 1. Set the control lever so that it contacts the full speed stopper bolt. 2. At the specified speed Nu, adjust using the full speed stopper bolt so that governing begins, then fix temporarily 3. Increase the speed and confirm that the specified rack position Ru can be obtained. 4. Adjust using the full speed stopper bolt so that governing begins at the specified speed Nf, then fix. 5. Confirm that the result is the same as that in '(5) Torque control spring adjustment.' 6. Confirm that the control lever operating angle is within the specifications. (7)Rack limit adjustment 1. Refer to the RLD type governor service manual (Publication no. EE13E-11083).
