Description
Technical field
The utility model relates to a kind of deaerator.
Background technique
Motor is in running, and the lower gas blowby at piston and rings place can mix machine oil oil droplet.As separated this machine oil oil droplet, will environment be produced greatly and be destroyed, deaerator can be realized the separation of mixed oil and gas.After filtering by deaerator, isolated machine oil oil droplet, this part machine oil can flow back to oil sump by the pipeline of a connection deaerator and crankcase (being deaerator return tube).
Deaerator return tube connects deaerator bottom topmost, directly communicates with external engine air, is connected bottom with crankcase.In the case, the oil gas in crankcase can directly enter into atmosphere by the return tube of deaerator; Also may occur that the machine oil that oil gas flow velocity in return tube is high and cause part to be filtered off is also blown to outside motor, cause engine oil consumption to increase.Therefore, at present motor mostly adopts direct insertion, U-shaped tubular type or one-way valve type structure, avoids mixed oil and gas directly to be entered suction tude or flowed into atmosphere by deaerator return tube.
At present, deaerator return tube mostly adopts direct insertion, U-shaped tubular type or one-way valve type, no matter which kind of structure, all can have the machine oil of certain liquid height, in the time that crankcase pressure moment increases in return tube, liquid level height can increase moment, greatly increase machine oil by lubricant pipe, through deaerator, enter the danger of suction tude or atmosphere.
Model utility content
The technical problems to be solved in the utility model is for above-mentioned defect, and a kind of deaerator that is beneficial to oil return is provided.
In order to solve the problems of the technologies described above, the crankcase steam outlet pipe that the utility model comprises deaerator, is communicated with crankcase, on described deaerator, be also provided with air outlet slit, its structural feature is between described deaerator and crankcase steam outlet pipe, to be communicated with rubber suction tude and rubber return tube, and described crankcase steam outlet pipe is provided with the lateral duct that inserts into the inner chamber and be communicated with rubber return tube.
Described lateral duct comprise the horizontal segment that stretches in crankcase steam outlet pipe and upwards bending, can install for rubber return tube vertical section.
Described deaerator is provided with can be for the deaerator suction tude that rubber suction tude is installed, and on described deaerator, being also provided with can be for the deaerator return tube that rubber return tube is installed.
Described horizontal segment and the vertically angle between section are acute angle or right angle.
The inner end of described horizontal segment is arranged on the central position in crankcase steam outlet pipe cross section.
The end face of the horizontal segment in described crankcase steam outlet pipe is inclined-plane.
The caliber of described lateral duct is less than the caliber of crankcase steam outlet pipe.
The caliber at described crankcase steam outlet pipe place reduces 10% ~ 20%.
Compared with prior art the utlity model has following advantage: the rubber suction tude being communicated with between deaerator and crankcase steam outlet pipe and rubber return tube, crankcase steam outlet pipe comprises lateral duct, and the end of lateral duct is inclined-plane and the central position that is positioned at crankcase steam outlet pipe cross section, can increase the negative pressure at lateral duct place, be conducive to the oil return of deaerator return tube; Suction tude is rubber pipe, and return tube is also rubber pipe, because rubber has plasticity, therefore can change arbitrarily its shape, and for convenience detach and replacing; The caliber of lateral duct is less than the caliber of crankcase steam outlet pipe, can realize gas backflow in return tube, and the oil return that also can realize deaerator refluxes smoothly; The caliber at crankcase steam outlet pipe place reduces, and can improve flow velocity, increases its negative pressure degree, is conducive to set up the pressure reduction at return tube two ends, realize smooth oil return, and the utility model is simple in structure, and oil return is effective.
Brief description of the drawings
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail:
Fig. 1 is structural representation of the present utility model;
Fig. 2 be in Fig. 1 A-A to sectional view.
Embodiment
As depicted in figs. 1 and 2, the crankcase steam outlet pipe 32 that this deaerator comprises deaerator 1 and is communicated with crankcase 2, on deaerator 1, be also provided with air outlet slit 5, between deaerator 1 and crankcase steam outlet pipe 32, be communicated with rubber suction tude 8 and rubber return tube 7, crankcase steam outlet pipe 32 is provided with the lateral duct 6 that inserts into the inner chamber and be communicated with rubber return tube 7, lateral duct 6 comprises horizontal segment and the upwards bending stretched in crankcase steam outlet pipe 32 as shown in Figure 2, can be set with for oil return rubber pipe 7 vertical section, angle in the present embodiment between horizontal segment and vertical section is preferably 90 °, in the present embodiment, vertically section keeps vertical state.The inner end of horizontal segment is arranged on the central position in crankcase steam outlet pipe 32 cross sections, can increase the negative pressure at this place, the end face of the horizontal segment in crankcase steam outlet pipe 32 is inclined-plane, the end face of horizontal segment also can be whittled into difformity, ensure that its end face is inclined-plane, can further increase the negative pressure at this place, be conducive to the oil return of deaerator return tube 18.In the present embodiment, deaerator 1 is provided with the deaerator suction tude 31 that can supply to install rubber suction tude 8, on deaerator 1, being also provided with can be for the deaerator return tube 18 that rubber return tube 7 is installed, one end of rubber suction tude 8 is sleeved on deaerator steam outlet pipe 31, the other end is sleeved on crankcase steam outlet pipe 32, one end of rubber return tube 7 is sleeved in lateral duct 6, the other end is sleeved on deaerator return tube 18, because rubber has plasticity, therefore can change arbitrarily its shape, and for convenience detach and replacing.
In the present embodiment, the caliber of lateral duct 6 is less than the caliber of crankcase steam outlet pipe 32.Based on bernoulli principle, can make like this negative pressure at lateral duct 6 places increase, can realize gas backflow in return tube, the oil return that also can realize deaerator refluxes smoothly.The caliber of crankcase steam outlet pipe 32 can suitably reduce, and the caliber in the present embodiment before the relative improvement of the caliber of crankcase steam outlet pipe 32 reduces 10% ~ 20%.According to bernoulli principle, dwindle caliber, can improve flow velocity, increase its negative pressure degree, be conducive to set up the pressure reduction at return tube two ends, realize smooth oil return.
The bottom angled setting of deaerator 1 as shown in Figure 2, rubber return tube 8 is positioned at the least significant end of the bottom of deaerator 1, ensures that the oil in deaerator 1 is concentrated outflow.Air outlet slit 5 be oppositely arranged with deaerator suction tude 31 and the position of air outlet slit 5 higher than the position of deaerator suction tude 31, guarantee that the gas mixture in deaerator 1 can directly not flow out from air outlet slit.
In the utility model, deaerator is not limit, can be mazy, multistage cyclone formula, filtering type etc.
The utility model is not limited to above-mentioned embodiment, and those skilled in the art, not departing under the prerequisite of spirit and scope of the present utility model, can do some changes and modification.Protection domain of the present utility model should be as the criterion with claim of the present utility model.
