Description
Technical field
The present invention relates to engine lubrication system technical field, be specifically related to a kind of electromotor cost, effectively of effectively reducing
Reduce engine motor oil air content, integrated engine oil scaleplate pipe, tension device and the electromotor rotor integrated machine of Oil-gas Separation function
Oil pump.
Background technology
During electromotor work, friction surface is (such as crankshaft journal and bearing, camshaft journal and bearing, piston ring and cylinder
Wall, timing gear wheel set etc.) between perform relative motion with the highest speed, the friction between metal surface not only increases in electromotor
The power consumption in portion, makes parts working surface wear and tear rapidly；The produced heat of friction is also possible to make some working part table
Face is melted, and causes electromotor to run well.Therefore for ensureing the normal work of electromotor, it is necessary to relatively transport in electromotor
Dynamic component surface is lubricated, and namely covers one layer of lubricant (machine oil or oils and fats) at friction surface, makes between metal surface
Between the thin oil film of alternating floor, to reduce frictional resistance, to reduce power attenuation, alleviate abrasion, increasing service life of engine.
If these surfaces not being lubricated, between them, strong friction will be there is.Dry friction between metal surface
Not only increase the power consumption of electromotor, accelerate the abrasion on part time job surface, but also be likely to be due to fricative heat and incite somebody to action
Part time job surface scaling loss, causes electromotor to operate.
Lubricating oil pump is most important parts in engine lube system, and its function is to provide enough pressure and flow for lube system
Machine oil, oil pressure must assure that in certain scope, to ensure that each friction member is sufficiently lubricated and do not damages phase
The pressure part closed.Lubricating oil pump has conclusive effect in the exploitation of whole engine lubrication system, and we can be whole
The blood circulation of lubricating system metaphor adult body, lubricating oil pump is exactly the heart of lubricating system, and each oil duct branch road is exactly blood
Pipe, lubricating oil pump provides the circulation of blood in the operation process of electromotor continuously for each parts, it is ensured that electromotor
Under each operating mode properly functioning.
On the one hand, along with the development of auto industry, the design competition of internal combustion engine is the most more and more fierce, and at car in modern age
On, owing to being limited by electromotor installing space, it is desirable to closely, meanwhile, densification is also that raising is interior to the structure of adnexa
One key factor of combustion engine competitiveness.In the design of former vehicle lubricating system, dipstick, tensioner mounting bracket,
Gas and oil separating plants etc., all design respectively as individual components.So making space arrange mixed and disorderly, product is in the competitiveness in market
Substantially weaken.
On the other hand, when electromotor works, the high pressure combustion mixture of combustor and burnt gas, more or less can lead to
Cross the gap between piston set and cylinder and leak in crankcase, cause gas blowby.The composition of gas blowby is unburned fuel vapor, steam
With waste gas etc., this can dilute machine oil, reduce the serviceability of machine oil, accelerates the oxidation of machine oil, goes bad.Condensation of moisture is at machine oil
In, greasy filth, clogged oil line can be formed；Sour gas in waste gas is mixed into lubricating system, can cause engine part corrosion and
Accelerated wear test；Gas blowby also can make the hypertonia of crankcase destroy the sealing of crankcase, makes engine oil leakage run off.
For preventing crankcase pressure too high, extend machine oil useful life, reduce parts depreciation and corrosion, prevent electromotor from leaking
Oil, it is necessary to carry out crankcase ventilation.Additionally, be to meet the emission request of increasingly stringent and improve economy, in automobile engine
Also must the design of march ventilation system for shaft box in design process.
Though a part for gs-oil separator only crankcase ventilation system, effect can't neglect, and, it unlike
As you think, its purpose is just made by the vacuum of steam intake manifold forces crankcase gas blowby to be discharged！
Gs-oil separator following points effect:
The first, cavaera, crankcase release it are forced to！This is topmost effect！The most how piston ring seals, and it also has
Gap, in addition itself has opening, although two seals ring with together with the opening of oil ring all stagger, but also can't stop cylinder
The crunch of interior mixed steam blast, still has partial high pressure waste gas and rushes in crankcase.So, present internal combustion engine is designed with
Crankcase ventilation system.Do not look down upon these waste gas, be mostly and be made up of the Hydrocarbon not burnt, these waste gas meetings
Water down, pollute machine oil, and also engine parts can be corroded.The most at high speed, serious gas blowby more can cause piston ring
And the scarce machine oil phenomenon between cylinder block, certainly, is expelled directly out, can pollute environment.The purpose of crankcase ventilation system is just
It is to guide these waste gas to enter cylinder second-time burning by air distribution system again, because themselves being flammable after entering steam intake manifold
Gas, reaches fuel-efficient purpose, but main purpose is to reduce the injury to engine of these gas blowbies, avoids it to enter atmospheric pollution ring simultaneously
Border.
The second, waste gas is purified.Gs-oil separator internal gas circulation so completes: the high temperature come in from valve-chamber cover
Waste gas, run into the Cryogenic air that (relative to the waste gas) come in from air filter upper strata filter through air filter and bump against, the machine oil in waste gas
Steam is with cold, and the oil droplet that congeals into falls down, and the pipe leading to air filter lower floor from gs-oil separator bottom is discharged car, it is ensured that secondary input is sent out
Machine oil is not had inside the waste gas of motivation.
3rd, control pollute, fuel-efficient.It is flammable that gs-oil separator has still existed after the waste gas of crankcase has been separated machine oil
Hydrocarbon secondary input electromotor, this is the most fuel-efficient.Gs-oil separator is mainly as far as possible machine oil vapor removal
For: machine oil (flowing back to oil sump), air (flow to inlet pipe and enter engine combustion), if it is damaged, mainly result in: electromotor is cold
Shake after startup, electromotor burn oil.
