Description
Technical field
This utility model relates to mechanical lubrication technical field, is specifically related to a kind of single plunger vacuum oil dripping type oil syringe.
Background technology
Oil syringe is one of capital equipment of centrifugal oil pump oil supply system.Constitute: main by jet pipe. mixing chamber and diffusion
Pipe forms.Pressure is accelerated in jet pipe by main oil pump, thus forms negative pressure in the mixing chamber of jet pipe.Due to negative pressure and freedom
The Involving velocity of jet, constantly brings diffuser pipe into by the oil in the mixing chamber in fuel tank, and miscella stream slows down in diffuser pipe and rises
Main oil pump is sent into or for bearing lubrication oil after pressure.
Existing oil syringe is primarily present the problem that fuel delivery cannot accurately regulate, and uses and regulates not only efficiency manually
Low, and degree of regulation is inadequate, easily causes device damage.
Utility model content
This utility model overcomes the deficiencies in the prior art, it is provided that a kind of single plunger vacuum that can accurately regulate fuel delivery is dripped
Oil formula oil syringe.
For solving above-mentioned technical problem, this utility model by the following technical solutions:. single plunger vacuum oil dripping type oiling
Device includes the oil syringe pump housing, and described pump housing bottom connects has fuel sucking pipe, top to be provided with fuel feeding valve, and the described pump housing is additionally provided with
Inverted U oil dripping tube, U-shaped oil dripping tube top is provided with pressure port, and pressure port surface is provided with caulking gum sheet, and sheet rubber outer surface is provided with
Pressure inductor；
The pump housing is provided with adjusting nut, and adjusting rod is positioned at adjusting nut, and lever is connected on the pump housing by fulcrum post
On pillar, driving means the eccentric cam driven contacts with lever one end, and the lever other end contacts with adjusting rod；
Plunger bushing one end is connected with described pump body, and plunger at one end enters the pump housing, the other end and lever through plunger bushing
Connect, between plunger bushing and plunger ring flat-plate, be provided with spring；
Pressure inductor is connected with driving means by controller.
Further, fuel feeding valve is provided with regulation ball with the junction of the described pump housing, and regulation ball surface is plastics.
The beneficial effects of the utility model are: when oil is through U-shaped oil dripping tube, can give one pressure of sheet rubber, feeling of stress
Answering device to be defeated by controller after gathering this force value, controller adjusts driving means duty according to force value, thus comes
Eccentric adjustment cam rotary speed.
Accompanying drawing explanation
Fig. 1 is the structural representation of utility model.
Fig. 2 is that this utility model controls schematic diagram.
Such as figure,1-fuel sucking pipe, 2-spring, 4-plunger, 5-plunger bushing, 6-regulates ball, the 7-pump housing, 8-oiling
Valve, 9-pressure inductor, 10-controller, 11-U type oil dripping tube, 12-sheet rubber, 13-adjusting nut, 14-adjusting rod,
15-pillar, 16-lever, 17-fulcrum post, 18-eccentric cam, 19-driving means, plunger ring flat-plate 20.
Detailed description of the invention
Such as Fig. 1, single plunger vacuum oil dripping type oil syringe includes the pump housing 7, and the pump housing 7 bottom connects has fuel sucking pipe, top to arrange
Having fuel feeding valve 8, the pump housing 7 is additionally provided with inverted U oil dripping tube 11, U-shaped oil dripping tube 11 top is provided with pressure port, and pressure port surface sets
Caulking gum sheet 12, sheet rubber 12 outer surface is had to be provided with pressure inductor 9；
The pump housing 7 is provided with adjusting nut 13, and adjusting rod 14 is positioned at adjusting nut 13, and lever 16 is connected by fulcrum post 17
On pillar 15 on the pump housing 7, driving means 19 eccentric cam 18 driven contacts with lever 16 one end, lever 16 another
End contacts with adjusting rod 14；
Plunger bushing 5 one end and the described pump housing 7 are internal to be connected, plunger 4 one end through plunger bushing 5 enter the pump housing 7, the other end and
Lever 16 connects, and plunger ring flat-plate 20 is located on plug 4, is provided with spring 2 between plunger bushing 5 and plunger ring flat-plate 20；
As in figure 2 it is shown, pressure inductor 9 is connected with driving means 19 by controller 10.
During work, eccentric cam 18 starts to rotate under the driving of driving means 19, and the part of eccentric cam 18 projection pushes away
Dynamic lever 16 rotates with fulcrum post 17 for axle, and lever 16 rotates and makes plunger 4 move up (going deep in the pump housing 7), eccentric cam 18
When non-protruding part contacts with lever 16, plunger 4 (leaves in the pump housing 7) under the effect of spring 2, moving back and forth of plunger 4
Produce negative pressure, make oil enter the pump housing 7 by fuel sucking pipe 1, and discharged the pump housing 7 by after U-shaped oil dripping tube 11 by fuel feeding valve 8, oil
During by U-shaped oil dripping tube 11, apply pressure can to sheet rubber 12, pressure inductor 9 this force value of Real-time Collection, and by pressure
Data input controller in real time, and controller, according to the change of force value, adjusts driving means 19 duty, driving means 19
After duty change, its eccentric cam 18 rotary speed also changes, and then makes plunger 4 move back and forth speed also to occur
Changing, it produces negative pressure value and also can change, and the size of the oil inlet quantity in the pump housing 7 is directly determined by vacuum magnitude.By right
The control of negative pressure, it is achieved accurate fuel feeding.
Preferably, fuel feeding valve 8 is provided with regulation ball 6 with the junction of the pump housing 7, and regulation ball 6 surface is plastics.
