Description
Technical field
The utility model relates to a kind of turbocharger protection device and method, particularly a kind of turbosupercharger intellective protector.
Background technique
Turbosupercharger utilizes motor combustion gas to drive turbine, turbine drives coaxial impeller again, impeller force feed is by air-strainer filtered air, make it supercharging and enter cylinder, when starting rotating speed to speed, the waste gas velocity of discharge and secondary speed also synchronously speed, the more air of wheel compresses enters cylinder, air pressure and density increase the more multi fuel that can burn, and increase the output power of motor, therefore turbocharging technology is widely applied.
For mass transit vehicle, be generally all provided with turbosupercharger now, mass transit vehicle more than 90 percent is all non-water-cooled pressurized machine, because it is often at a high speed, works under high temperature temperature, requires very high for its protection maintenance.
1, because pressurized machine is positioned at engine oil lubrication distalmost end, during pressurized machine work, its maximum speed reaches and per minutely tens thousand ofly goes to 200,000 turns, bearing used is floating bearing, floating bearing, under the pressure and rotating shaft turning effort of lubricant oil, carrying oil film is formed at its inner and outer surface, make rotor, bearing and bearing support work under non-contact condition, in engine starting process, supercharger rotor works, now because engine motor oil is delayed, bad wearing and tearing are caused to pressurized machine, vehicle need not also require to do pre-lubrication to the artificial lubricating oil filling of pressurized machine oil input channel more than (one week) for a long time, idling 3-5 minute after starting.
2, after high engine speeds running, can not stop working immediately, necessary idling 5 minutes, when reason is engine operation, supply pressurized machine machine oil is used for the lubrication and cooling of supercharger rotor and bearing, after unexpected shutdown, engine oil pressure is zero, oil lubricating interrupts, pressurized machine internal heat cannot be taken away by machine oil, at this moment booster turbine part conducts heat to bearing, temperature in bearings shell continues to raise, and simultaneously supercharger rotor still High Rotation Speed under effect of inertia, can cause like this and kill between supercharger rotor and bearing and damage bearing and axle, suddenly the temperature of flame-out final vacuum pipe and waste gas volute is very high, the machine oil coking being trapped in pressurized machine inside is formed carbon deposit (machine oil coking temperature about 230 degree) by (more than 600 degree) its heat, filler opening will be blocked when carbon deposit is cumulative, cause axle sleeve oil starvation, acceleration turbine rotor and bearing wear increase resistance simultaneously, bearing heating, vicious circle makes turbocharger impairment.(delivery temperature about 200 degree during idle running, idling 5 minutes objects drop to less than 230 degree to charge temperature).
Chinese patent literature publication number is IO2536441A; patent name is " automatic protection device for exhaust gas turbocharger "; comprise storage battery, power switch, relay, machine oil pressure warning sensor; electromagnet, initial lubrication accumulator and flame-out lubrication accumulator, described storage battery, power switch, relay, machine oil pressure warning sensor are connected by wire successively with electromagnet.Can store when using the utility model can ensure engine work and there is certain lubricant oil.When the engine is started, provide certain lubricant oil to turbine shaft and bearing in advance by Fuel Tanking Unit, when engine stop rotates, play the effect of lubrication turbine shaft and bearing, thus decrease the damage of exhaust-gas turbocharger.Its Problems existing is: realize entering of lubricant oil by electromagnet, spring and piston, and its reliability is bad, easily breaks down, and can not extensively be applied; In addition, do not form a product directly can installed yet, make it reequip work difficulty larger.
In addition, to install minitype carrier vehicle and the family-sized car of turbosupercharger: general employing water-cooled pressurized machine, although volute temperature is too high after not having vehicle flame-out, cause the problem of carbon distribution, after switch-off, turbine remains under the effect of inertia, continue to do high speed rotary motion, and lubrication system now decompression quitting work, this just causes the wearing and tearing of turbine, reduce the working life of turbine, add the burden of car owner; And dilly does not have pre-lubrication system, so also there is the turbine wear problem at vehicle launch initial stage yet, cause decline the working life of turbine.
