Description
Technical field
The utility model relates to vehicle lubrication device, particularly a kind of auxiliary delay oil supplying device of exhaust-gas turbocharger.
Background technique
At present, the application of exhaust-gas turbocharger on big-and-middle-sized diesel engine is general, and it has tangible effect to aeration quantity, the raising engine power that improves motor.In real work, usually finding has the working life of many exhaust-gas turbochargers shorter, and its phenomenon is pressurized machine body drain oil, and abnormal noise is arranged.What have also can cause lubricant oil to be inhaled into the air inlet volute and enter cylinder, causes burn oil, makes the serious carbon deposit in firing chamber.
Causing pressurized machine short reason in working life, mainly is two aspects: the one, and the driver misoperation, flame-out immediately after the high engine speeds running, another is that the lubrication system architecture of pressurized machine own causes.
The automobile exhaust-gas turbocharger is to utilize the energy impact turbo machine of engine exhaust to rotate, and the gas compressor that drives the other end by an axle rotates, and realizes the purpose of calming the anger to gas handling system.The rotating speed of turbo machine can change up to per minute 100,000, and the lubricated of it is by the lubricant oil of in-engine oil pump to turbo machine force feed certain pressure, realizes pressure lubrication.Machine oil after lubricated flows back to oil sump by return tube.
Flame-out after the high engine speeds running, oil pump has just stopped fuel feeding at once, the axle of turbo machine is also running up, but also a period of time of will remaining in operation just can stop, turbine shaft is in unlubricated state during this period of time, close to dry friction, temperature can very fast rising, can increase the wearing and tearing of bearing, life-span influence to the pump shaft oil sealing is very big, if the driver have run up after flame-out custom (the old driver who has likes banging suddenly two foot throttles before flame-out) immediately, will have a strong impact on working life of turbo machine so.Through extensively retrieval, still find no relevant technological scheme.
The model utility content
The purpose of this utility model be for solve present stage diesel-oil vehicle flame-out after no longer to the shortcoming of exhaust-gas turbocharger fuel feeding, and the auxiliary delay oil supplying device of a kind of exhaust-gas turbocharger that proposes.To achieve these goals, the utility model has adopted following technological scheme:
A kind of auxiliary delay oil supplying device of exhaust-gas turbocharger comprises turbosupercharger, and described turbosupercharger comprises shell, connects turbo machine and gas compressor respectively on the both sides of shell, and turbo machine connects gas compressor by running shaft, bearing set on running shaft.Connect a seal ring respectively at the two ends of shell, on shell, also be provided with inflow pipeline and flowline, make lubricant oil enter the turbocharger lubrication bearing from inflow pipeline and flow back to oil sump by flowline.It is characterized in that also comprising:
Tank body is provided with opening in the rear end of tank body, at the opening top cover that is connected, is provided with air equalizer opening at the end face of top cover.Be provided with the plunger that is slidingly matched in tank body, plunger is connected with a side of diaphragm backplate by piston spring, and the opposite side of diaphragm backplate is connected on the top cover by diaphragm spring again.Diaphragm of clamping between two diaphragm backplates, the two ends of diaphragm all connect between tank body and the top cover.Front end at tank body is provided with pipeline, and pipeline connects one of them outlet of three-way valve, and another outlet of three-way valve connects the inflow pipeline of turbosupercharger, and the entrance of three-way valve is by pipeline junctor oil pump.In pipeline, by the flow-limiting valve that is threaded, be provided with metering-orifice at flow-limiting valve.
On the basis of technique scheme, following further technological scheme can be arranged:
Described diaphragm backplate is made up of upper guard board and following backplate, accompanies diaphragm between upper guard board and following backplate.
The rear end of described tank body is provided with lower flange, and lower flange is corresponding with the upper flange on top cover, at lower flange and upper flange uniform four corresponding screws all.Tank body, diaphragm and top cover are linked together by bolt at screw.
Described tank body is connected on the turbosupercharger, be to be used for pressure inside and outside the balance when lubricant oil enters housing internal air pressure equalizing orifice in the purpose that the end face of top cover is provided with air equalizer opening, metering-orifice on the described flow-limiting valve forms metering hole in pipeline, its effect is that lubricant oil is played certain metering function, makes the initial stage of engine start guarantee that turbo machine has sufficient lubricating oil.
Advantage of the present utility model is: this device working stability is reliable, and is little to the lubricating fitting change of former car, and can not increase extra power consumpiton to vehicle, also can not influence the proper functioning of the lubrication system of former car even this device breaks down.
Description of drawings
Fig. 1 is basic structure schematic representation of the present utility model.
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, it is characterized in that also comprising:
Be provided with the plunger 12 that is slidingly matched in tank body 10, plunger 12 is connected with the side of diaphragm backplate 13 by piston spring 17, is being connected on the top cover 16 by diaphragm spring 15 on the another side of diaphragm backplate 13.Diaphragm backplate 13 is made up of upper guard board and following backplate, and upper guard board is pasted together with viscose and diaphragm 14, and diaphragm 14 sticks on down on the backplate with viscose again.The periphery of diaphragm 14 extends between lower flange 10a and the upper flange 16a, and by bolt 18 compression fit.
Front end at tank body 10 is provided with pipeline 10c, and pipeline 10c is connected with the back outlet 9b of three-way valve 9, and the preceding outlet 9a of three-way valve 9 connects inflow pipeline 8, and the entrance 9c of three-way valve 9 is connected with oil pump.In pipeline 10c, by the flow-limiting valve 11 that is threaded, be provided with metering-orifice 11a at flow-limiting valve 11.
Working principle
Behind engine start, lubricant oil enters three-way valve from oil pump, and the lubricant oil overwhelming majority flows to turbosupercharger in order to lubricating bearings under the effect of flow-limiting valve, and lubricated back lubricant oil enters oil sump by flowline.Wherein small part lubricant oil enters tank body.The purpose that flow-limiting valve is set is to guarantee that at the initial stage of engine start turbo machine has the sufficient lubricating oil amount.
After the oil mass of tank body increased gradually, the compression plunger spring promoted plunger and moves up, and plunger top volume dwindles, and pressure raises, and promotes the diaphragm assembly to arch, simultaneously the compressive films flat spring.The chamber of diaphragm top is because volume dwindles, and the air that air chamber is compressed passes through outside the atmospheric equilibrium mouth drain tank.When diaphragm arch reach capacity and plunger on move when reaching capacity, jar oil-filled amount in chamber reaches maximum, and keeps motionless.The lubricant oil that comes from oil pump again will all enter turbosupercharger for lubricated later on.
After motor quits work, the oil pump fuel cut-off, but turbine is still in rotation at a high speed, at this moment, this device beginning fuel feeding is namely under the acting in conjunction of piston spring and diaphragm spring, plunger moves down compresses into turbosupercharger with the lubricant oil in the tank body by flow-limiting valve, and bearing is lubricated.Lubricant oil after lubricated flows back to oil sump by the return tube of former car.
