(l)S series governor
EP/RSV represents the full program governor; EP/RS represents the bipolar governor; EP/RSUV stands for full-speed governor.
200~1100 - represents the speed range of the governor in r/min. A -- represents the supporting fuel pump series, such as M, A, 2W, MW and P, etc.
The Numbers in the grid represent O~9 of the revolution. For example, 0 indicates that it is a special flying hammer and speed regulating spring, and the combination determines the speed range. 1 represents 200~ 1400r/min; 5 represents 250~ 1600r/min; 9 represents 500~3000r/min.
String - the letters in the space represent the design variation code of the governor :A represents the first time; B stands for the second time; C stands for the third time; 0 is the fourth grade.
Torque - the number in a box represents the design symbol number of the governor.
1 -- represents the code number of the governor control mechanism: 1 represents the non-governor lever; 2 represents no stop rod; 3 represents the yuan stop device; The 4 - generation meter has no speed regulating rod and stop rod.
D -- represents the calibration device of the governor :0 represents the calibration device of the governor controlled by the spring; K represents the governor's correction device controlled by the calibration CAM.
R -- represents the installation position of the governor :R represents the installation position of the governor on the right of the fuel injection pump; L represents the installation position of the governor on the left of the fuel injection pump.
(2)Q series governor
RQ - stands for bipolar governor :RQV stands for full program governor; RQU represents a bipolar speed governor; RQUV stands for full-speed governor. Rqv-k represents a full-program governor with torque control. 200~1100 -- represents the speed range of the fuel pump, and the unit is r/min.
A -- represents the series of fuel injection pumps used for governor, such as A, P, MW, ZW, etc.
The letters in the grid represent the design variation code of the governor :A represents the first time; B stands for the second time; C is the third time, and so on.
String - the number in the box represents the design logo.
1 -- represents the code number of the governor control mechanism: 1 represents the yuan governor rod; 2 represents no stop rod; 3 represents the yuan stop device; The 4 - generation meter has no speed regulating rod and stop rod.
D -- represents the calibration device of the governor :D represents the calibration device of the governor controlled by the spring; K represents the governor's correction device controlled by the calibration CAM.
R -- represents the installation position of the governor :R represents the installation position of the governor on the right of the fuel injection pump; L represents the installation position of the governor on the left of the fuel injection pump.
(3) air film governor
EP/M -- represents the air film governor.
The letters in the grid represent idle speed control mode of the governor :N represents CAM adjustment; 2 represents screw adjustment. 60 -- indicates that the diameter of the diaphragm is 60mm.
Parliamentary -- the letters in the grid represent the supporting fuel injection pump series of the governor :M and A.
