The digital signals such as sulfur content, cylinder sleeve and the piston set break-in state of oil, provide optimal confession after calculating
Oil mass, and then control moment of described suction ferrum switch motion and actuating quantity to realize the accurate note of cylinder oil
Enter.Moreover, it is also possible to as required, according to the operating mode of diesel engine on man-machine interaction panel automatically or
Manually regulation injection flow and oiling timing.The operation principle of described control unit 2 and circuit belongs to ability
The conventional design of field technique personnel, does not repeats them here.
The principle that this lubricating system changes injection flow is as follows:
1) zero injection flow:
Now, described plunger 1f turns to zero oil mass passage 1f2 thereon and is directed at described oil return opening 1e's
Position, during moving up and down at described plunger 1f, described plunger cavity 1c is all the time by described
Zero oil mass passage 1f2 connects with described oil return opening 1e, thus the oil pressure in described plunger cavity 1c all the time with
Oil pressure in described oil return opening 1e is identical (for low oil pressure), and therefore, described oil syringe 1 cannot realize
Oiling i.e. injection flow is zero (seeing Fig. 7)；
2) centre note oil mass:
Now, described plunger 1f turns to control slot 1f3 thereon towards described oil return opening 1e's
Position, so, at described plunger 1f during extreme lower position moves upward to extreme higher position, institute
State plunger 1f and only just the fluid in described plunger cavity 1c can be carried out pressurization realization note in the incipient stage
Oil；When described plunger 1f moves to the position that described control slot 1f3 connects with described oil return opening 1e
Time, due to described plunger cavity 1c by described zero oil mass passage 1f2 and described control slot 1f3 with
Described oil return opening 1e connects, so the hydraulic oil in described plunger cavity 1c just runs through described oil return opening
1e is down to low pressure oil state, and described oil syringe 1 just cannot realize oiling；Therefore, at described plunger 1f
Whole stroke in, only the incipient stage can oiling, so by rotate described plunger 1f, regulation
Control slot 1f3 diagonally disposed on it, towards the position of described oil return opening 1e, changes described plunger
The pressure stroke of 1f just can realize the arbitrarily regulation (seeing Fig. 6) of injection flow；
3) maximum injection flow:
Now, described plunger 1f turns to it and is not provided with described zero oil mass passage 1f2 or described oil mass
The sidewall of regulating tank 1f3 is directed at the position of described oil return opening 1e, due to the fortune up and down at described plunger 1f
During Dong, described plunger cavity 1c does not connects with described oil return opening 1e, so in whole up mistake
Fluid in described plunger cavity 1c can be pressurizeed by Cheng Zhong, described plunger 1f all the time, it is achieved maximum oil mass
Oiling (sees Fig. 5).
The work process of the present invention is as follows:
First, described tappet 1g moves up and down under the rotation of described camshaft 1h；Meanwhile, institute
State tappet 1g drive described plunger 1f move upward, rise to when the end face of described plunger 1f described in enter
During hydraulic fluid port 1d and more than oil return opening 1e, the sidewall of described plunger 1f just cuts off described oil-in 1d and returns
The connection of hydraulic fluid port 1e and described plunger cavity 1c, described plunger 1f starts the oil in described plunger cavity 1c
Liquid pressurizes, when in described plunger cavity 1c, oil pressure exceedes the setting value of described draining valve assembly 1l, and high pressure
Oil will pass through described draining valve assembly 1l, oil pipe and pump nozzle 1a oiling in cylinder 3；Endure when described
When post 1g moves downward, described plunger 1f oil pressure in described plunger cavity 1c and the common work of gravity
Move downwardly together with described tappet 1g under with, when the end face of described plunger 1f drops to described oil-in
During below 1d, described oil-in 1d connects with described plunger cavity 1c, and the fluid in oil supply unit 4 is just
Enter in described plunger cavity 1c by described oil-in 1d, it is achieved the filling of fluid；At electromotor
In running, described control unit 2 can control described driving in real time according to the actual condition of electromotor
Device 1k drives described tooth bar 1j to move, so that described gear 1i rotates adjusts described plunger 1f's
Turned position, it is achieved the adjustment of injection flow.
The present invention adds zero oil mass passage 1f2 and control slot by using on plunger 1f sidewall
1f3, and with control unit 2 control in real time described driving means 1k drive described tooth bar 1j move, from
And make described gear 1i rotate the technical scheme of the turned position adjusting described plunger 1f, having reached can root
The purpose of injection flow, simple in construction and low cost it is automatically adjusted according to electromotor actual condition.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all at this
Within bright spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in
Within protection scope of the present invention.
