For achieving the above object, the present invention provides following technical scheme: a kind of hydrodynamic governor, including shell and the fly weight being arranged on enclosure；Described fly weight is connected and speed bar is positioned at fly weight center of rotation by fly weight support and speed bar are fixing；Described speed bar is connected with rocking bar by hinge and rocking bar one end is fixing with the compensating piston being arranged within fluid servomotor is connected；Buffer is installed between described compensating piston and rocking bar and inside is connected with Throttle needle valve by pipeline；Described Throttle needle valve drives axle top with being arranged on and connects with gear oil pump；Described compensating piston one end and the counterbalance spring compact siro spinning technology being fixed on shell；Described enclosure arranges connecting rod and is positioned at speed bar one end；Described connecting rod is connected with the axle shaft gear being arranged on bottom fluid servomotor.
Further, described counterbalance spring, buffer and compensating piston are positioned on the same axis of enclosure.
Further, described fluid servomotor is positioned at buffer right-hand member, and the lower end of fluid servomotor is truncated cone-shaped structure.
Further, described buffer inside for T-shaped structure and can be moved at compensating piston.
Further, described counterbalance spring welds with rocking bar, and counterbalance spring inside is connected by nut with compensating piston.
Compared with prior art, the invention has the beneficial effects as follows: the counterbalance spring of this kind of hydrodynamic governor, buffer and compensating piston are positioned on the same axis of enclosure, when making decelerator work, sensitivity is higher；Fluid servomotor is positioned at buffer right-hand member, and the lower end of fluid servomotor is truncated cone-shaped structure, and what make speed regulator uses the gap between material saving and inside less；Counterbalance spring is internal with rocking bar welding and counterbalance spring to be connected by nut with compensating piston, makes speed regulator can regulate the scope of rotating speed according to user, and this kind of hydrodynamic governor is easy to use, degree of regulation and highly sensitive, good stability, wide accommodation, practical, it is suitable for promoting the use of.

Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention; technical scheme in the embodiment of the present invention is clearly and completely described; obviously; described embodiment is only a part of embodiment of the present invention; rather than whole embodiments; based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of protection of the invention.
Referring to Fig. 1-2, the present invention provides a kind of technical scheme: a kind of hydrodynamic governor, including shell 13 and be arranged on the fly weight 3 within shell 13；Described fly weight 3 is fixed with speed bar 1 by fly weight support 2 and is connected and speed bar 1 is positioned at fly weight 3 center of rotation；Described speed bar 1 is connected with rocking bar 5 by hinge and rocking bar 5 one end is fixing with the compensating piston 8 being arranged within fluid servomotor 7 is connected；Buffer 6 is installed between described compensating piston 8 and rocking bar 5 and the internal pipeline that passes through connects with Throttle needle valve 9；Described Throttle needle valve 9 drives axle 11 top with being arranged on and connects with gear oil pump 10；Described compensating piston 8 one end and counterbalance spring 4 compact siro spinning technology being fixed on shell 1；Described shell 13 is internal to be arranged connecting rod 12 and is positioned at speed bar 1 one end；Described connecting rod 12 is connected with driving axle 11 gear being arranged on bottom fluid servomotor 7；The counterbalance spring 4 of described hydrodynamic governor, buffer 6 and compensating piston 8 are positioned on the same axis within shell 13, and when making decelerator work, sensitivity is higher；Fluid servomotor 7 is positioned at buffer 6 right-hand member, and the lower end of fluid servomotor 7 is truncated cone-shaped structure, and what make speed regulator uses the gap between material saving and inside less；Counterbalance spring 4 welds with rocking bar 5 and counterbalance spring 4 is internal is connected by nut with compensating piston 8.
nullConcrete principle as the present invention: this speed regulator increases an elastic link in inside，It is by buffer 6、Compensating piston 8、Counterbalance spring 9、Throttle needle valve 10 forms elastic link，It is filled with working oil in buffer 6 oil cylinder，Two spaces, left and right are connected by pipeline and Throttle needle valve 10,When moving left and right after buffer 6 stress，In buffer 6 cylinder, liquid flows another space from a space through Throttle needle valve 10，Owing to the throttling of Throttle needle valve 10 makes the movement of compensating piston 8 more delayed than the movement of buffer 6，Play cushioning effect,The function of the flexible recovery of counterbalance spring 9 owing to being compressed，A point is made to drive compensating piston 6 to move right in buffer oil cylinder，Return to origin-location，Oil in the oil cylinder of compensating piston right is back to left through Throttle needle valve 8，Last counterbalance spring 9 and rocking bar 5 all return to origin-location，Speed bar 1 is made to also return to original position,Such speed regulation process terminate after engine speed former speed can be kept constant,Play speed governing cushioning effect.
Using method as the present invention: when changing oil, hot drain the oil, when diesel engine just stops, state bleeds off lubricating oil while hot, it is filled with the light diesel fuel of cleaning, compensating needle valve opens several turns, start diesel engine by speed regulator one minute self-cleaning internal galleries of fluctuation, machine is put diesel oil only after stopping, if the diesel oil released is dirtier, can again be filled with the light diesel fuel of cleaning, again clean as stated above, change new lubricating oil to regulation oil level, the fluctuation of speed is artificially made to carry out purging, adjust compensating needle valve, after short-time running, the lubricating oil newly changed is bled off again, it is then injected into new lubricating oil.
Last it is noted that the foregoing is only the preferred embodiments of the present invention; it is not limited to the present invention; although the present invention being described in detail with reference to previous embodiment; for a person skilled in the art; technical scheme described in foregoing embodiments still can be modified by it; or wherein portion of techniques feature is carried out equivalent replacement; all within the spirit and principles in the present invention; any amendment of being made, equivalent replacement, improvement etc., should be included within protection scope of the present invention.
