Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment; technological scheme in the utility model embodiment is clearly and completely described; obviously; described embodiment is only the utility model part embodiment; instead of whole embodiments; based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
Refer to Fig. 1-2, the utility model provides a kind of technological scheme: diesel engine highi degree of accuracy speed regulator, comprises shell 13 and is arranged on the fly weight 3 of shell 13 inside; Described fly weight 3 to be fixedly connected with speed bar 1 by fly weight support 2 and speed bar 1 is positioned at fly weight 3 rotating center; Described speed bar 1 to be connected with rocking bar 5 by hinge and rocking bar 5 one end is fixedly connected with the compensating piston 8 being arranged on fluid servomotor 7 inside; Described compensating piston 8 with between rocking bar 5, buffer 6 is installed and inside is communicated with Throttle needle valve 9 by pipeline; Described Throttle needle valve 9 is arranged on live axle 11 top and is communicated with gear oil pump 10; Described compensating piston 8 one end and counterbalance spring 4 compact siro spinning technology be fixed on shell 1; Described shell 13 inside arranges connecting rod 12 and is positioned at speed bar 1 one end; Described connecting rod 12 is connected with live axle 11 gear be arranged on bottom fluid servomotor 7; The counterbalance spring 4 of described diesel engine highi degree of accuracy speed regulator, buffer 6 and compensating piston 8 are positioned on the same axis of shell 13 inside, and when retarder is worked, sensitivity is higher; Fluid servomotor 7 is positioned at buffer 6 right-hand member, and the lower end of fluid servomotor 7 is frustoconic shape structure, the use material of speed regulator is saved and gap between inside is less; Counterbalance spring 4 welds with rocking bar 5 and counterbalance spring 4 inside is connected by nut with compensating piston 8.
As concrete principle of the present utility model: 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, working oil is filled with 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 is stressed, in buffer 6 cylinder, liquid flows to another space from a space through Throttle needle valve 10, throttling due to Throttle needle valve 10 makes the movement of compensating piston 8 more delayed than the movement of buffer 6, play buffer function, due to by the function of the flexible recovery of counterbalance spring 9 compressed, A point is made to drive compensating piston 6 to move right in buffer oil cylinder, get back 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 also to get back to initial position, engine speed after such speed regulation process terminates can keep former speed constant, play speed governing buffer function.
As using method of the present utility model: when changing oil, hotly to drain the oil, when diesel engine just stops, state bleeds off lubricating oil while hot, be filled with clean Diesel oil, compensating needle valve opens several turns, start diesel engine to fluctuate one minute self-cleaning internal galleries by speed regulator, machine stops rear diesel oil is put only, if the diesel oil of releasing is dirtier, can again be filled with clean Diesel oil, again clean as stated above, change new lubricating oil to regulation oil level, people carries out purging for making the fluctuation of speed, adjust compensating needle valve, after short-time running, the lubricating oil newly changed is bled off again, then new lubricating oil is injected.
Last it is noted that the foregoing is only preferred embodiment of the present utility model; be not limited to the utility model; although be described in detail the utility model with reference to previous embodiment; for a person skilled in the art; it still can be modified to the technological scheme described in foregoing embodiments; or equivalent replacement is carried out to wherein portion of techniques feature; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
