Description
Technical field
The utility model relates to turbo-charger technical field, particularly a kind of for the sealing configuration on turbocharger air compressor.
Background technique
Turbosupercharger is to utilize engine exhaust to drive, the air density that compression enters motor, thus increase cylinder volumetric efficiency, by improving engine combustion, to reach, strengthen power character, Eco-power object.Under the dual test of current fuel crises and Abgasgesetz; turbosupercharger is used more and more extensive; technology for Turbocharger Manufacturing is also more and more ripe, and VNT and two-step supercharging technology have all obtained developing rapidly, and turbosupercharger and Engine Matching technology are gradually improved.Yet the reliability of turbosupercharger becomes the key issue of turbosupercharger development, wherein turbosupercharger leakage and oil-break are the principal elements that affects Reliability of Turbochargers, therefore design a kind of good gas compressor end seal lubrication structure most important.
The compressor end sealing structure of turbosuperchargers generally adopting is at present as shown in Figure 2: comprise and be arranged on the split washer 2-5 on rotor shaft 2-2 between middle case 2-3 and compressor impeller 2-4, oil sealing cap seal ring 2-6, oil sealing cap 2-7, thrust bearing 2-8, seal ring 2-9, stuffing box gland 2-10 and thrust housing 2-11.Lubricant oil enters from the oil inlet hole of middle case 2-3, by oilhole, flow to thrust bearing 2-8, the lubricant oil that enters thrust bearing 2-8 flows to a side of stuffing box gland 2-10 and oil sealing cap 2-7 by the oilhole on thrust bearing 2-8 and oil groove, the upper processing oil closure gasket groove of stuffing box gland 2-10, pressure side seal ring 2-9 is assemblied between stuffing box gland 2-10 and oil sealing cap 2-7 endoporus, when lubricant oil enters in the gap that oil sealing cap 2-7 endoporus and stuffing box gland 2-10 form, the effect of pressure side seal ring 2-9 is exactly to prevent that lubricant oil from entering in the cavity that impeller 2-4 wheel is carried on the back and the end face of oil sealing cap 2-7 forms.
When turbosupercharger and motor joint work, motor itself can produce leakage contribution to pressurized machine,
Such as when too high, the air filtering obstruction of crankcase pressure, underrun and return tube design not at that time, pressure in middle case 2-3 all can be higher than compressor impeller 2-4 wheel counterpressure, thereby make lubricant oil leak into the cavity of the wheel back of the body of compressor impeller 2-4 and the end face formation of oil sealing cap 2-7 and then enter gas compressor from pressure side seal ring 2-9, form oil leakage fault.In addition, it is upper that each obturator of gas compressor end is all assemblied in the turbine rotor 2-13 of High Rotation Speed, so each part must have good lubricating ability, so just should not be because oil starvation causes core sintering generation machine failure in High Rotation Speed process.In a word, the particularity of engine operation and the special construction of pressurized machine, all determined sealing and lubricating ability that turbocharger air compressor end must be indispensable good, and therefore optimizing gas compressor seal lubrication structure has become matter of utmost importance.
1. sealing problem: turbosupercharger gas-tight sealing system of rotaty is very ripe, on the basis guaranteeing at part processing precision, the seal ring of pressurized machine can guarantee the hermetic seal of pressurized machine completely.And due to the key issue of the not good enough straight puzzlement pressurized machine of pressurized machine leakage of oil one reliability causing of each obturator of gas compressor end design.The structure that gas compressor end respectively seals component directly affects calming the anger of gas compressor side pressure end seal ring 2-9 both sides and oil sealing oil return effect, therefore improves the gas compressor that pressurized machine sealing must improve and optimizate existing pressurized machine and respectively seals component structural.
2. lubrication: each obturator of gas compressor end not only has outside material impact pressurized machine sealing, also most important to pressurized machine core part lubrication.Owing to forming each part of gas compressor end seal action, be also pressurized machine core vital part simultaneously, directly affect the axial-radial gap of whole pressurized machine, and these parts are to be all assemblied on the turbine rotor of High Rotation Speed to move, therefore the lubricant oil that enters bearing support must be to these part sufficient lubrications, if cause part oil starvation sintering for shortage of oil or lubricated insufficient meeting, directly cause pressurized machine machine failure.
