Description
Technical field
The utility model relates to a kind of active deaerator, belongs to crankshaft of diesel engine box ventilation system Oil-gas Separation technology, belongs to automobile technical field.
Background technique
Crankcase ventilation system is the important constituent element of motor, and along with the increasingly stringent of Abgasgesetz, crankcase ventilation system also becomes the content of examination of regulation gradually.The GB11340 put into effect for such as 2005 just explicitly calls for petrol engine to adopt closed crankcase ventilation system.Although at present not to diesel engine mandatory requirement, in Europe six Abgasgesetz of up-to-date appearance, explicitly point out the waste gas that crankcase ventilation system is discharged to be introduced directly in tail gas and carry out unifying to detect.The enforcement of this regulation, can produce great pushing effect to crankcase ventilation system correlation technique undoubtedly.At present, domestic Medium or severe type diesel engine adopts open-circuit ventilation form substantially, and deaerator is as the core component of crankcase ventilation system, and its structure mostly is mazy type or Cyclone.This Oil-gas Separation technology due to its separation effect low, so be difficult to the requirement meeting closed crankcase ventilation system.Force employing that efficiency of turbocharger reduction, intercooler oil-feed and consumption of lubricating oil will be caused abnormal, and finally cause the problem such as overall performance, reliability decrease.
Summary of the invention
The purpose of this utility model is to provide a kind of active deaerator, and it can solve the problem that Medium or severe type diesel engine adopts overall performance and reliability decrease after closed crankcase ventilation system.
The technical solution of the utility model is achieved in that active deaerator, it is characterized in that: base assembly upper end is fixedly connected with upper housing assy, there is seal ring the joint of base assembly and upper housing assy, base assembly inner chamber is oil back chamber, upper housing assy inner chamber lower end is equipped with outlet chamber assembly, " O " RunddichtringO is provided with between outlet chamber assembly and upper housing assy, driving shaft assembly is arranged vertically in the cavity that base assembly and upper housing assy form, the part that driving shaft assembly is positioned at base assembly has auxiliary separating from impeller, the below of driving shaft assembly has machine oil spray orifice, the part that driving shaft assembly is positioned at housing assy is overlapped from bottom to up and is had lamination lower body, lamination, lamination upper body, lamination lower body limited location spring retainer, lamination upper body has jump ring spacing, pressing plate is had in upper housing assy upper side lid, pressing plate place is furnished with diaphragm, keep maximal clearance between diaphragm and air outlet, diaphragm is by pressure regulator valve spring supporting.
Good effect of the present utility model is that to which solve Oil-gas Separation product oil-gas separation efficiency in the market low, cannot meet the problem of closed crankcase ventilation system; Structure is simple, is convenient to complete machine and arranges; Lifelong service free, reduces customer using cost; Reliability is high, is applicable to the Medium or severe type diesel engine being required to meet Europe six Abgasgesetz.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is active oil-gas separator structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further: as Fig. 1, shown in Fig. 2, active deaerator, it is characterized in that: base assembly 1 upper end is fixedly connected with upper housing assy 10, base assembly 1 has seal ring 11 with the joint of upper housing assy 10, base assembly 1 inner chamber is oil back chamber 17, upper housing assy 10 inner chamber lower end is equipped with outlet chamber assembly 4, " O " RunddichtringO 12 is provided with between outlet chamber assembly 4 and upper housing assy 10, driving shaft assembly 2 is arranged vertically in the cavity that base assembly 1 and upper housing assy 10 form, the part that driving shaft assembly 2 is positioned at base assembly 1 has auxiliary separating from impeller 3, the below of driving shaft assembly 2 has machine oil spray orifice 18, the part that driving shaft assembly 2 is positioned at housing assy 10 is overlapped from bottom to up and is had lamination lower body 6, lamination 5, lamination upper body 7, lamination lower body 6 limited location spring 8 is spacing, lamination upper body 7 has jump ring 9 spacing, pressing plate 15 is had in side cover 13 above upper housing assy 10, pressing plate 15 place is furnished with diaphragm 14, keep maximal clearance between diaphragm 14 and air outlet, diaphragm 14 is supported by pressure regulator valve spring 16.
Extreme pressure lubricant enters in driving shaft assembly 2 by base assembly 1, and the machine oil spray orifice 18 along rotating center symmetry being 1.8mm by the diameter of two on driving shaft assembly 2 sprays.The couple that oil injection is formed drives driving shaft around central rotation; Lamination 5, lamination upper body 7 and lamination lower body 6 are fixed on driving shaft assembly 2 by limit spring 8 and jump ring 9, and carry out High Rotation Speed along with driving shaft assembly 2; The lamination of crankcase waste gas by High Rotation Speed of deaerator inside is now entered into by upper housing assy 10.Rotating the centrifugal force produced can make the liquid oil droplet in crankcase waste gas and particulate matter fly away from lamination and strike on the wall of housing assy 10, thus completes oil, gas separation process.Clean gas after separation can enter deaerator air outlet by outlet chamber assembly 4, and isolated oil droplet and particle can enter oil back chamber 17 by outlet chamber assembly 4.
Because the utility model is applied on closed crankcase ventilation system, so need to flow through the parts such as suction tude, pressurized machine, intercooler by the gas after Oil-gas Separation, and finally enter firing chamber participation burning.When the pressure that the negative pressure of crankcase and the negative pressure in pressure regulator valve outlet port produce with when being less than the pretightening force of pressure regulator valve spring 16, pressing plate 15 is had in side cover 13 above upper housing assy 10, pressing plate 15 place is furnished with diaphragm 14, maximal clearance is kept between diaphragm 14 and air outlet, diaphragm 14 is supported by pressure regulator valve spring 16, and along with the increase of pressure regulator valve outlet port negative pressure, pressure regulating spring 16 compresses, gap between diaphragm 14 and air outlet reduces gradually, until completely closed.
Owing to machine oil can be caused to splash when high pressure oil is sprayed onto oil back chamber 17 by machine oil spray orifice 18, so add auxiliary separating from impeller 3 between outlet chamber assembly 4 and oil back chamber 17.It to be fixed on driving shaft assembly 2 and High Rotation Speed thereupon.Stop the oil droplet of splashing to enter in outlet chamber assembly 4 under the influence of centrifugal force, thus ensure completely cutting off between oil back chamber 17 and outlet chamber assembly 4.
