Description
Technical field
The utility model relates to a kind of car engine machine technology, especially a kind of high-order suction tude with secondary draining.
Background technique
At present, engine air inlet tube is motor desired gas passage, and air is removed airborne water droplet by suction tude, avoids motor because of the air water droplet detonation to take place too much, thereby motor is played a protective role.Especially in heavy rain, travel or stop and water inlet very easily takes place too much under the flame-out situation, motor is damaged.The suction tude drainage pattern that at present domestic and international auto vendor generally adopts mainly is that design eddy flow impeller unit or electronics butterfly valve etc. add mechanism and reach drainage effect by the increase filter screen.Though these methods can effectively reduce the water inlet of motor, complex production process, cost is higher, the resource cost amount is bigger.
The model utility content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, a kind of high-order suction tude with secondary draining is provided, and this suction tude need not any peripheral hardware mechanism can realize the drainage effect identical with adding peripheral hardware mechanism, has simplified production procedure, reduce cost of production, saved resource.
For achieving the above object, the utility model adopts following technical proposals:
A kind of high-order suction tude with secondary draining, the suction tude middle part offers suction port on the side, the suction port place is provided with grid, the suction port bottom has first drain opening that communicates with the external world, vertically be provided with the first aqueous vapor separating plate in the suction tude relative with suction port, the side of the first aqueous vapor separating plate closely links to each other with the suction tude inwall respectively with the base, and upper side and suction tude inwall have the space; The first aqueous vapor separating plate bottom, and the suction tude inwall relative with its position is provided with the second aqueous vapor separating plate that oblique camber down extends; The top of the second aqueous vapor separating plate closely links to each other with the suction tude inwall respectively with side, and is gapped between bottom and the corresponding suction tude inwall; Second aqueous vapor separating plate bottom margin below is provided with second drain opening that communicates with the external world, other the 3rd aqueous vapor separating plate that extends obliquely that is provided with of second drain opening, the bottom of the 3rd aqueous vapor separating plate links to each other with the second drain opening edge, and side closely links to each other with the suction tude inwall; The suction tude bottom is connected with empty filter; Described first, second, third aqueous vapor separating plate is separated into S shape gas-entered passageway with suction tude inside.
Described grid is by the intake grill place of rivet in suction tude.
The bottom of the described first aqueous vapor separating plate is curved, the top of the first aqueous vapor separating plate is to the suction tude inwall bending corresponding with it, and the lateral cross section that forms between this place's first aqueous vapor separating plate and the suction tude inwall is long-pending more than or equal to 20% of empty filter cross-section of pipeline area.
Form a low wide and up narrow intake grill passage between the described first aqueous vapor separating plate and the suction tude inwall.
Described the 3rd aqueous vapor separating plate is curved, and the part of the longitudinal projection of second, third aqueous vapor separating plate coincides.
In order not allow the water droplet that enters suction tude directly enter the sky filter, intake grill of the present utility model is opened in the side, middle part of whole suction tude, and the outside is added with grid, with the intake grill place of rivet in suction tude.The intake grill bottom has first drain opening, and the intake grill passage is low wide and up narrow, forms the water droplet windage, can effectively stop water droplet to enter the opposite side tube chamber, and the water droplet more than 95% is hindered in first drain opening.Air flue is upwards by changing another downward tube chamber over to behind 1 180 ° the turning, this tube chamber bottom is offered second drain opening and is reached air flue obliquely, gas moves upward along air flue obliquely in tube chamber, be inhaled into the water droplet of tube chamber on a small quantity, then fall under gravity into second drain opening, turning back again after gas makes progress enters the sky filter by connection mouth downwards.By twice filtration, just unnecessary water droplet is kept off fully in the outside like this, guaranteed the safety of motor.
In order to increase the effect of draining for the first time, the reduced cross-sectional area of the peak that the air water fluid-mixing is climbed, but be not less than sky filter pipeline section long-pending 20%, under the prerequisite that guarantees system wind resistance, widen the ratio of suction port sectional area and this place's sectional area, cause the air pressure difference at two sections place to strengthen, than a lot of slowly at the peak place, the resistance of air at suction port place will be less than the peak place at the suction port place for air velocity, the suffered suction of suction port water droplet is less, falls easily.
The suction port sectional area should be done greatly as far as possible, but be subjected to the restriction of body dimensions, opening can't be accomplished infinity, so still having a spot of raindrop can be inhaled into, therefore need further stop the more raindrop of minor diameter with the 3rd aqueous vapor separating plate, so before the fluid that air water mixes enters into the sky filter, be provided with air-water separation passage for the second time in the suction tude bottom, allow the bigger water droplet of inertia collide on the air intake pipe inwall, flow into second drain opening, be discharged to the outside, gas then enters another tube chamber along passage obliquely.
In addition, air intake filter screen (being grid) is designed in the side, and in order to reduce windage, the opening of filter screen is also done greatly as far as possible, reduce air to the shearing force of raindrop.
By above twice drainage procedure, the water droplet in the gas substantially all keeps off in empty filter outside.The utility model was done simulation at truck.In the motor experiment of drenching with rain under the state of operation continuously, according to 6m
3The super extra torrential rain amount of/3min, the inflow of empty filter has only 2ml, has reached usage requirement fully.
The utility model is foundation with the air rheology on the basis of mechanics principle, and suction tude structurally is optimized design, need not any peripheral hardware mechanism and can realize the drainage effect identical with adding peripheral hardware mechanism thereby reach.The utility model has been simplified production procedure, has reduced cost of production, has saved social resources, thereby can form good social benefit.
