Description
Technical field
The present invention relates to the vehicle component oil supply lubrication device, particularly a kind of turbosupercharger postpones oil supplying device.
Background technique
At present, the application of exhaust-gas turbocharger on big-and-middle-sized diesel engine is general, and it has obvious 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, is mainly 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 turn 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 remaining in operation just can stop, turbine shaft is in unlubricated state during this period of time, close to dry friction, temperature can raise very soon, can increase the wearing and tearing of bearing, life-span impact on the pump shaft oil sealing is very large, if the driver have run up after flame-out custom (the old driver who has likes suddenly banging two foot throttles before flame-out) immediately, will have a strong impact on so working life of turbo machine.Through extensively retrieval, still find no relevant technological scheme.
Summary of the invention
The objective of the invention is for solve present stage diesel-oil vehicle flame-out after no longer to the shortcoming of exhaust-gas turbocharger fuel feeding, and a kind of turbosupercharger that proposes postpones oil supplying device.
To achieve these goals, the present invention has adopted following technological scheme:
A kind of turbosupercharger postpones oil supplying device, comprises turbosupercharger, and described turbosupercharger comprises shell, connects respectively turbo machine and gas compressor on the both sides of shell, and turbo machine connects gas compressor by running shaft, bearing set on running shaft.Connect respectively a seal ring at the two ends of shell, also be provided with inflow pipeline and flowline on shell, make lubricant oil enter the turbocharger lubrication bearing from inflow pipeline and flow back to oil sump by flowline.Characterized by further comprising:
Connecting tank body on turbosupercharger, is hatch frame in the rear end of tank body, connects a diaphragm on opening, and top cover is housed above diaphragm, is provided with air equalizer opening on the end face of top cover.When lubricant oil enters housing internal air pressure equalizing orifice for pressure inside and outside balance.
Be provided with the plunger that is slidably 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 top cover by diaphragm spring again.Diaphragm of clamping between two diaphragm backplates, the two ends of diaphragm all connect between tank body and top cover.
Front end at tank body is provided with pipeline, one of them outlet of pipeline connecting tee 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.Be threaded connection flow-limiting valve in pipeline, be provided with metering-orifice on flow-limiting valve.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 lubricant oil.
On the basis of technique scheme, following further technological scheme can be arranged:
Described diaphragm backplate is comprised of upper guard board and lower backplate, accompanies diaphragm between upper guard board and lower 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.
The invention has the advantages that: 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 affect the normal operation of the lubrication system of former car even this device breaks down.
Description of drawings
Fig. 1 is basic structure schematic diagram of the present invention.
Embodiment
As shown in Figure 1, a kind of turbosupercharger provided by the invention postpones oil supplying device, comprises turbosupercharger 20, and described turbosupercharger 20 comprises shell 1, connects respectively turbo machine 4 and gas compressor 5 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 on shell 1, characterized by further comprising:
Be provided with the plunger 12 that is slidably matched in tank body 10, plunger 12 is connected with the side of diaphragm backplate 13 by piston spring 17, is being connected on top cover 16 by diaphragm spring 15 on the another side of diaphragm backplate 13.Diaphragm backplate 13 is comprised of upper guard board and lower backplate, and upper guard board is pasted together with viscose and diaphragm 14, and diaphragm 14 sticks on lower backplate with viscose again.The periphery of diaphragm 14 extends between lower flange 10a and 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 rear outlet 9b of three-way valve 9, and the front 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.Be threaded connection flow-limiting valve 11 in pipeline 10c, be provided with metering-orifice 11a on flow-limiting valve 11.
Working principle
After 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 rear 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 sufficient lubricants capacity.
After the oil mass of tank body increased gradually, the compression plunger spring promoted plunger and moves up, and above plunger, 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 atmospheric equilibrium mouth drain tank.When diaphragm arch reach capacity and plunger on move when reaching capacity, it is maximum that the oil-filled amount in tank chamber reaches, and keep motionless.The lubricant oil that comes from oil pump more later on will all enter turbosupercharger and be used for lubricated.
After engine stop work, the oil pump fuel cut-off, but turbine is still at High Rotation 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 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.
