Embodiment
As shown in Figure 1, the auxiliary delay oil supplying device of a kind of exhaust-gas turbocharger that the utility model provides comprises turbosupercharger 20, and described turbosupercharger 20 comprises shell 1, connects turbo machine 4 and gas compressor 5 respectively on the both sides of shell 1.Turbo machine 4 connects gas compressor 5 by running shaft 6, also is connected with bearing 2 on running shaft 6.Be respectively equipped with inflow pipeline 8 and flowline 7 at shell 1, inflow pipeline 8 and flowline 7 are connected, and it is characterized in that also comprising:
In the rear end of valve body 10, portion is provided with two end cap oilhole 16a by threaded ends 16 at adjustment end cap 16 within it, and valve body 10 communicates by end cap oilhole 16a and oil storage tank 17.Be provided with the main valve 11 that is slidingly matched in valve body 10, described main valve 11 connects one group of main valve spring 14 for having the opening cylinder of ladder 11b between ladder 11b and adjustment end cap 16.The opening of main valve 11 is crossed center line at base plate and is provided with central oilhole 23a by the base plate 23 that is threaded.Match with end cap oilhole 16a at the bottom of the valve of main valve 11.
At the bottom of the valve of main valve 11, cross center line and be provided with through hole 11a, in main valve 11, be provided be slidingly matched auxiliary-valve 12, the bottom of described auxiliary-valve 12 is provided with base 12a, be provided with directional post 12b at base 12a, be provided with at least one at directional post 12b and adjust packing ring 15, directional post 12b matches with through hole 11a.Between at the bottom of the valve of base 12b and main valve 11, be provided with one group of auxiliary-valve spring 13.Side in valve body 10 is provided with side opening 10b, and valve body 10 is connected with oil storage tank 17 by side opening 10b.
Front end at valve body 10 is provided with pipeline 10a, one of them outlet of three-way valve 9 before pipeline 10a connects, and preceding three-way valve 9 another outlets also are connected inflow pipeline 8 and oil pump respectively with entrance.
Working principle
Behind the engine start, the lubricant oil that is transported by oil pump is to the turbo machine fuel feeding, because the firm entry into service of motor, the quantity and the pressure that are positioned at the exhaust-gas turbocharger machine oil of lubricating system end are not very high, can not back down main valve, the bypass oil duct is in closed condition, and the machine oil that come by oil pump this moment all enters pressurized machine, guarantees that pressurized machine has enough lubricant oil.
After the pressure of lubricant oil was elevated to certain value, unnecessary machine oil flowed to valve body by preceding three-way valve, first jack-up main valve, and compression main valve spring rises main valve.This moment, lubricant oil entered the auxiliary-valve chamber by the central oilhole on the base plate, and compression auxiliary-valve spring is closed auxiliary-valve.Final main valve rises to and props up the adjustment end cap, closes the end cap oilhole.
When main valve is elevated to when exposing side opening, lubricant oil just enters oil storage tank by side opening.After machine oil is full of oil storage tank, unnecessary machine oil by oil returning tube through after three-way valve flow back to oil sump.The effect of metering hole is to prevent that too much lubricant oil from flowing back into oil sump by oil returning tube, influences the lubricant oil quantity of turbo machine.
Behind engine misses, oil pump fuel cut-off, turbo machine also will continue to operate a period of time, the engine oil pressure that acts on the main valve below this moment is 0, main valve moves down under the effect of main valve spring, has opened the end cap oilhole, and main valve is taken a seat and closed side opening.But the central oilhole in this process on the base plate is unimpeded.
Because the oil pump fuel cut-off, the pressure balance of auxiliary-valve is at this moment broken, and the pressure of auxiliary-valve below is 0, and the auxiliary-valve spring begins to uphold, and under the effect of auxiliary-valve spring, auxiliary-valve is lifted off a seat, and oil circuit is connected.The lubricant oil of oil storage tank by the oil channel hole on the end cap of valve termination, auxiliary-valve, main valve central authorities oilhole, enter preceding tee union, flows to turbo machine at last under the effect of self gravitation.
After the lubricant oil of oil storage tank flowed out, the space increased in the oil storage tank, vacuum occurs, at this moment replenished air by oil returning tube, realized pressure balance, guaranteed that the lubricant oil of oil storage tank can all flow out.
The main valve spring tension is regulated by adjusting end cap.During the precession end cap, the main valve spring tension increases, and the pressure that main valve is opened also increases.On this end cap oilhole is arranged, when main valve is opened maximum, close oilhole, when engine stoping operation, main valve is descending, and this oilhole is opened, and guarantees that oil storage tank communicates with auxiliary-valve.The auxiliary-valve spring tension is regulated by the quantity of adjusting packing ring.
