Embodiment:
Governor spring in this intermediate support pressure spring type mechanical governor, idle spring is positioned on the spring seat by central spindle of the spring, speed governing rocking arm pulling central spindle of the spring produces and gives compression, the speed-regulating arm upper end links to each other with the movable spring seat by hinge, the speed governing driving lever is fixed together by jack shaft and casing, the upper end of speed governing driving lever is linked to each other with the centre of driven lever by hinge, and the lower end is press-fitted negative school swivel nut; The negative correction push rod is housed in the swivel nut, and an end contacts with the speed governing sliding sleeve, and the other end contacts with screw on the negative correction rocking arm, and the other end of rocking arm contacts with the transmission push rod that be equipped with the speed regulator lower end, and the transmission push rod contacts with the speed governing driving lever; Supercharging compensation transmission levers upper end links to each other with hinge, and diaphragm is delivered on the hinge by booster rod with the variation of inflation pressure, the controlled lever restriction in transmission levers lower end; The driven lever upper end links to each other with buoyant beam, and buoyant beam connects the fuel-flow control ratch, the controlled lever restriction in lower end.
During diesel engine starting, the fuel-flow control ratch is positioned at the automatic start excess fuel device of low order end under the effect of primer spring.After the starting, engine speed rises, and flies piece and opens under centrifugal action, promotes move right speed governing driving lever and transmission push rod of sliding sleeve and collides, the speed governing driving lever is rotated around jack shaft under the promotion of sliding sleeve, drives the oil mass position before follower lever moves to the supercharging compensation.Rotating speed further rises, the engine charge boost pressure has overcome the tight power of giving of boost compensator spring, booster rod drives the pin hinge and moves downward, force transmission levers to move downward, drive the control lever and rotate, make follower lever around hinge through, cause the fuel-flow control ratch to move right, increase oil mass, contact with supercharging compensation stroke limit screw, finish the supercharging compensation process up to supercharging compensation rocking arm.Rotating speed continues to rise, according to motor actual conditions needs, the power that speed-regulating arm acts on the positive correction push rod begins less than the positive correction spring force, the positive correction push rod is pushed speed-regulating arm left open, the moving driving lever of band speed governing is rotated, force the fuel-flow control ratch to be moved to the left and reduce oil mass, contact with school swivel nut just, finish the positive correction process up to positive correction push rod omoplate position.Along with rotating speed continues to rise, the power that the speed governing sliding sleeve acts on the negative correction push rod begins greater than the tight power of giving of negative correction spring, the negative correction push rod promotes the negative correction rocking arm and rotates, the negative correction rocking arm promotes the transmission push rod and moves, the transmission push rod forces driving lever to be rotated around jack shaft, makes the fuel-flow control ratch move right, and increases oil mass, stroke limit screw on the negative correction rocking arm contacts with speed-regulating arm, finishes oil mass negative correction process.The oil mass ratch is parked in specified oil mass position, when rotating speed surpassed rated engine speed, the moment that flies the generation of piece thrust surpassed governor spring and gives the moment that tight power produces, and the speed governing sliding sleeve is pushed speed-regulating arm open and moved right, drive the fuel-flow control ratch and be moved to the left to cut-out position, realize the automatic control of oil mass.Pulling governor spring mandrel is in diverse location, can change the tight power of giving of governor spring, thereby the control diesel engine speed is realized omnidistance control; The precession of positive correction push rod and back-out can change the position of fuel-flow control ratch, thus quota stand oil amount.
Its advantage of the advantage that the utility model compared with prior art has be multiple functional, with low cost, Appearance and size is little, allowable rotating speed is high, can satisfy the requirement of modern engine with supercharger, can be widely used in fortune The diesel engine of the various uses such as defeated vehicle, engineering machinery, farm machinery and Diesel engine uses.
