Description
Technical field
The present invention relates to the plug-in respiratory organ structure of a kind of Diesel Engine Breather, specifically multi-cylinder diesel engine, belongs to bavin
Oil machine respiratory organ technical field.
Background technology
Diesel Engine Breather is not only essential and extremely important as an exclusive part of electromotor. Wo Menzhi
Road, diesel engine when normal work operates, in order to ensure friction pair can obtain effectively lubricating, exist in addition machining accuracy and
The reasons such as error, have certain interval between the reciprocating piston pair of high speed and cylinder wall（Otherwise, electromotor arises that drawing
Cylinder phenomenon, this will cause catastrophe failure）, therefore as the continuous reciprocating motion of piston has less during engine work
Amount pressure high temperature hot gas are continuously leaked in crankcase from combustor through this gap, cause the pressure in crankcase continuous
Increase;On the other hand, with the work of electromotor, the temperature of the sealing position such as valve cover can also reach a relatively high temperature
Degree, causes internal pressure to rise.Lubricating oil with cooling function is also continuously by the partial heat of higher temperature part
Take back oil sump, cause oil sump temperature constantly to rise, diesel engine oil pan temperature up to 110 DEG C, at this temperature, in machine oil
Lightweight volatile component constantly evaporate, be further exacerbated by the rising of crankcase pressure；If being discharged not in time,
The each sealing surface of diesel engine even body just has the danger that rises brokenly.Therefore equal in order to ensure diesel engines and atmospheric pressure
Weighing apparatus, diesel engine need to install respiratory organ additional.
Existing respiratory organ structure is common following three kinds：
1. crankcase bottom is located at, because nearer apart from crankcase position herein, absolute distance is short, so exhaust resistance is little, but
Its delivery temperature can be higher, and work has oil dripping phenomenon after a period of time.
2. engine valve cover top is located at：Can be better to Oil-gas Separation, but occupancy volume is larger, and Oil-gas Separation is not
Thoroughly.
3. respiratory organ is connected with air inlet：Exactly respiratory organ expellant gas are introduced directly into diesel engine air inlet system, carry out
Second-time burning, can cause NOx exceeded if Oil-gas Separation is bad, atmosphere pollution.

Upper end is provided with dividing plate, and dividing plate by upper shell and is usherd to seat lower housing cavity parting seal；Set in the middle part of filter screen bracket inner tube external surface
Have upper filter screen support, filter screen bracket inner tube external surface lower end is provided with lower filter screen support, upper filter screen support and lower filter screen support it
Between be provided with filter screen；Usher to seat lower house lower end connection back leakage connection；Upper shell upper end connects top cover, and upper casing body side surface is provided with aerofluxuss and connects
Mouthful.
Further, lower casing external surface both sides of usheing to seat are provided with fixed seat.
Further, back leakage connection and usher to seat between lower house lower end and be provided with check valve.
Further, upper filter screen support and lower filter screen support are conical structure, on upper filter screen support and lower filter screen support
It is provided with multiple for by the opening of machine oil, multiple openings are uniform along upper filter screen support and lower filter screen support conical surface
Distribution.
Further, top cover inner surface is provided with oil absorbent material.
Further, the entrance point of exhaust port stretches into upper shell center and is open towards top cover.
Compared with the prior art the present invention has advantages below：
Present configuration is simple, compact, reasonable, and Oil-gas Separation is thorough, reduces atmospheric pollution, while reducing consumption of lubricating oil, reduces
Customer using cost, using can meet national emission request on state four, five diesel engine of state；Easy to assembly, will to locus
Ask not high, fix in certain space of diesel engine.
