Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment oil-gas separating device for engine is described in detail.
The utility model embodiment provides a kind of oil-gas separating device for engine, comprise oil-gas separation chamber 11, oil-gas separation chamber 11 is communicated with oil and gas import 12 and oil gas vent 13 respectively, oil gas vent 13 comprises gas outlet 131 and return opening 132, in oil-gas separation chamber 11, be provided with rotating impeller 14, impeller 14 is arranged between oil and gas import 12 and oil gas vent 13, and the blade 141 of impeller 14 is netted blade.
In the oil-gas separating device for engine that the utility model embodiment provides, be provided with oil-gas separation chamber, oil-gas separation chamber is communicated with respectively oil and gas import and oil gas vent, and oil gas vent comprises gas outlet and return opening, in addition, in oil-gas separation chamber, be provided with rotating impeller between oil gas suction port and oil gas vent, the blade of this impeller is netted blade.Analyze thus knownly, when motor is worked under running on the lower load, oil and gas content is less in crankcase, and now impeller does not rotate substantially, but still can carry out Oil-gas Separation by the collision with fuel-air mixture; When motor is worked under middle and high load working condition, in crankcase, oil and gas content is very large, thereby fuel-air mixture promotes impeller, occurs to rotate continuously, carries out Oil-gas Separation.Therefore, this deaerator all can be realized Oil-gas Separation under the different operating modes of automobile, and does not need the power of extra consumption of engine, and practicability is high.
It should be noted that, the varying strength (comprising speed and pressure) that rotatable impeller in the present embodiment can enter suction port according to fuel-air mixture produces different rotating speeds, thereby can meet the requirement of the Oil-gas Separation of automobile under the different operating modes such as low speed, high speed.
Simultaneously, the fuel-air mixture entering in deaerator has certain pressure, thereby promote impeller and rotate motion, therefore known, mode by air work, when reaching the object of Oil-gas Separation, can also reduce the pressure loss of the deaerator inside of automobile under different operating modes.
When automobile low speed driving, motor is worked under running on the lower load, in crankcase, oil and gas content is less, the underpressure of common fuel-air mixture is in such cases rotated continuously to blow impeller, fuel-air mixture and impeller bump and carry out Oil-gas Separation, in this process, self pressure of fuel-air mixture is less, so its pressure loss in deaerator is also very little.
When galloping, motor is worked under middle and high load working condition, oil and gas content in crankcase is many, therefore enter the pressure of the fuel-air mixture of oil and gas import 12, speed is also larger, the rotating speed of impeller 14 is also large and can rotate continuously accordingly, easily cause impeller 14 after carrying out Oil-gas Separation, there will be and get rid of oily phenomenon, being machine oil after separation is thrown toward oil gas vent 13 regions with the rotation of impeller 14, easily make machine oil hang over the position that is unfavorable for oil return on deaerator inwall, cause the problems such as oil return is not smooth, therefore, in oil-gas separation chamber 11, between rotatable impeller 14 and oil gas vent 13, can be provided with baffle plate 15, this baffle plate 15 can keep off the machine oil being thrown out of after separation in lower above-mentioned situation effectively.Wherein, because the machine oil being separated need to carry out oil return by return opening 132, so be provided with gap between baffle plate 15 and the lower surface of oil-gas separation chamber 11.This wherein, air outlet 131 can be arranged at the upper surface of oil-gas separation chamber 11, return opening 132 can be arranged at the lower surface of oil-gas separation chamber 11, thereby make to give vent to anger and oil return operation between there is independence.
In Fig. 1, oil and gas import 12 can be communicated with by oil and gas pipes 16 with the crankcase of motor; Gas outlet 131 can be communicated with by outlet pipe 17 with the suction tude of motor; Return opening 132 can be communicated with by oil returning tube 18 with the crankcase of motor, and oil and gas pipes 16 and oil returning tube 18 can vertically arrange downwards, outlet pipe 17 can vertically make progress setting.
Wherein, oil and gas pipes 16, oil returning tube 18 and outlet pipe 17 arrange can increase corresponding fuel-air mixture from crankcase to oil and gas import the distance between 12, the machine oil after separation from return opening 132 to the distance crankcase and the gas separation from gas outlet 131 to the distance suction tude.Thereby fuel-air mixture is applied to before impeller 14, becomes and more relax, be convenient to fuel-air mixture and carry out Oil-gas Separation operation by the collision with impeller 14; The setting of oil returning tube 18 can be played the effect of collecting machine oil, avoids occurring the phenomenon of local trapped fuel, and the oil level after simultaneously collecting is many, and whole gravity is larger, is convenient to, by the oil return of machine oil self gravitation, improve oil return efficiency; And outlet pipe 17 can make gas after separation the process from gas outlet 131 to suction tude, deposit the effect by self gravitation of a little machine oil within it further from wherein separating, to reach fully the effect of Oil-gas Separation.
In the structure of the deaerator shown in Fig. 1, no matter motor is under running on the lower load or under middle and high load working condition, machine oil after separation all need to flow with oil return along the lower surface of oil-gas separation chamber, therefore between baffle plate 15 and the lower surface of oil-gas separation chamber 11, there is gap, and this gap can be between 2mm to 5mm, can certainly be other gap length, make the machine oil after separation and the machine oil that kept off by baffle plate 15 can both carry out oil return by this gap, improve oil return efficiency.
It should be noted that herein, the distributed architecture of each parts and relative position relation each other in deaerator shown in Fig. 1, be only the structure of binding engine and a kind of preferred embodiment of processing and forming technology, it can certainly be other set-up mode.
In addition, the length of oil and gas pipes 16, outlet pipe 17 and oil returning tube 18 can need to set according to the structure of motor and actual demand.
Concrete, when baffle plate 15 is set, it can be located at the arbitrary position on the deaerator inwall between impeller 14 and oil gas vent 13, but as preferably, be located at the section that enters respectively the airflow of gas outlet 131 and return opening 132 after fuel-air mixture separation, be that machine oil after separation and gas are being divided into two strands through after baffle plate 15, along gas outlet 131 and return opening 132 separately, give vent to anger and oil return operation respectively, so baffle plate 15 is located at, and above-mentioned section makes the machine oil after separation and gas is directly given vent to anger after baffle plate 15 and oil return operation, prevent that gas from taking away a part of machine oil again, improve oil gas separation.
In the process of practical operation, when operator easily find that machine oil carries out oil return operation by self gravitation in oil returning tube 18, when machine oil flows out inflow crankcase from oil returning tube 18, if this place is made as throat structure, can make machine oil oil return in oil returning tube 18 concentrate, now return opening 132 can be circular hole, and oil returning tube 18 is cylindrical-shaped structure, can certainly be other structure, for example rectangular or taper.
It should be noted that herein, when machine oil passes through oil returning tube 18 oil return, conventionally also need a return tube that oil returning tube 18 is connected to below crankcase machine oil liquid level, thereby make the pressure in oil returning tube 18 not be subject to external influence, avoid the not smooth problem of oil return.
Therefore, consider the object that oil return is even and concentrated, can be successively decreased along oil return direction in the cross section of the oil returning tube of cylindrical-shaped structure 18, thereby make its formation be similar to the structure of funnel, make oil return homogenization.Wherein, outlet pipe 17 also can be made the mode that its cross-sectional sizes is successively decreased successively along outgassing direction, thereby reduce the speed of giving vent to anger, increase the time that the gas after separation stops in outlet pipe 17, can make to exist a little oil droplet in gas more effectively by self gravitation, again to be separated, improve oil gas separation.
Certainly, for the requirement of air inflow and air inlet pressure etc. in oil and gas pipes 16, also can make throat structure as shown in Figure 1, thereby when can control air inflow, can also make oil gas even.Now oil and gas pipes 16 can extend the distance between oil and gas import 12 and crankcase, the structure of the oil and gas pipes 16 shown in while Fig. 1, after making fuel-air mixture via oil and gas pipes 16, after turning, be applied to impeller 14, effectively make to act on the gas pressure intensity homogenization of impeller 14, prevent impeller 14 and neglect soon slow rotation suddenly, improve oil gas separation effect herein.
In the oil-gas separating device for engine that above-described embodiment is described, as depicted in figs. 1 and 2, impeller 14 can comprise that the corresponding deaerator inwall of the rotatingshaft 141(being located on deaerator inwall is provided with the mounting hole of rotatingshaft 141) and be fixedly located at a plurality of blades 142 on rotatingshaft 141; On each blade 142, be evenly provided with a plurality of mesh 21.Impeller 14 is mainly used in the separation of oil gas, therefore blade 142 is only set to platy structure, thereby by the shock of oil gas, reaches the object of Oil-gas Separation, and the separating effect of this kind of mode is not high, and crushing is larger, therefore the structure that can increase oil gas separation need to be set on blade 142.Employing in the present embodiment arranges a plurality of mesh 21 on a plurality of blades 142, can increase the area of contact of fuel-air mixture and blade 142 by mesh 21, has effectively improved oil gas separation.
Wherein, for the quantity of blade 142 and the quantity of the mesh 21 on each blade 142, be not all restricted, with the numerical value obtaining through test of many times, be as the criterion, the arrangement mode of the mesh 21 on blade 142 can adopt the form of matrix simultaneously, evenly reliable.Certainly, the shape of mesh 21 can, for circular (diameter is at 1mm to 5mm), rectangle or other polygonal etc., also can adopt other arrangement mode.
According to the theory of above-mentioned raising oil gas separation, gas oil separation structure on blade 142 also can be for adopting other modes, for example, can on blade 142, set up a plurality of dividing plates, each dividing plate is the edge direction setting parallel with rotatingshaft 141 on blade 142, thereby increases the area of contact of fuel-air mixture and blade 142.
In practical operation, impeller 14 carries out Oil-gas Separation by rotation, gas after separation and machine oil are sent into oil gas vent 13 directions simultaneously, therefore, in the situation that not affecting impeller 14 rotation, shorten the marginal end of blade 142 of impeller 14 and the distance between oil-gas separation chamber 11 inwalls as far as possible, thereby avoid fuel-air mixture to walk around impeller 14, directly arrive oil gas vent 13, affect oil-gas separation efficiency.Material and cost in conjunction with actual processing, can have slight distance, but this distance is very little on the impact of oil gas separation, can ignore between the marginal end of blade 142 and the inwall of oil-gas separation chamber 11.
After passing through the Oil-gas Separation of impeller 14, the machine oil after separation flows in oil returning tube 18 along oil-gas separation chamber 11 lower surfaces.Therefore, in order to facilitate machine oil flowing on oil-gas separation chamber 11 lower surfaces, the lower surface of oil-gas separation chamber can be made as to streamlined structure, thereby machine oil can well flow and oil return along this streamlined structure.Certainly, the gas after separation can blow the motion of machine oil after separation equally, therefore above-mentioned streamlined structure can make machine oil more efficiency carry out oil return.
This wherein, the distance between impeller 14 and oil and gas pipes 16 can be zero, also can be greater than zero.When oil level after separation is larger, may fail all to enter in time in oil returning tube 18, cause part machine oil to be thrown toward oil and gas pipes 16 directions with the rotation of impeller 14, cause the inefficient problem of oil return, therefore by increasing the distance between impeller 14 and oil and gas pipes 16, can reduce the incidence rate of above-mentioned situation, indirectly improve oil return efficiency.
