Description

The fuel economizer suction tude of double-type eddy current blended fuel oil and air
Technical field
The utility model relates to a kind of suction tude, relates in particular to the fuel economizer suction tude of a kind of double-type eddy current blended fuel oil and air.
Background technique
Carburetor is under the vacuum action producing in engine operation, the mechanical device that a certain proportion of fuel oil is mixed with air; Carburetor is as a kind of mechanical device of precision, it can be referred to as " heart " of motor to the important function of motor, wherein the trunnion of Carburetor is as the place of a kind of blended fuel oil and air, wherein the flow velocity of air has determined the degree of mixing to a certain extent, the suction tude of simultaneously current connecting engine only plays the effect of conduit, if fuel oil and air are unmixed in trunnion, evenly can not further mix it, may cause fuel utilization ratio to reduce.
Model utility content
The purpose of this utility model is just to provide in order to address the above problem the fuel economizer suction tude of a kind of double-type eddy current blended fuel oil and air.
The utility model is achieved through the following technical solutions above-mentioned purpose:
The fuel economizer suction tude of a kind of double-type eddy current blended fuel oil and air, comprise trunnion and jet pipe, described trunnion comprises small venturi and large trunnion, the oil outlet end of described jet pipe is communicated with described small venturi, the lower end of described small venturi is arranged in the upper end of described large trunnion, and between the inwall of described large trunnion and the outer wall of described small venturi, be provided with gap, on described gap, be provided with air conduit, the lower end of described large trunnion is provided with rotatable solar term plate.
The twin-choke that large trunnion and small venturi combine, when identical air inflow, the degree of vacuum of nozzle exit end is large, and the relative flowing velocity of fuel oil and air increases, and fuel oil reduces from the particle of oil nozzle ejection, and the quality of atomization improves.
Particularly, described solar term plate is circular corrosion protection rubber plate, on described solar term plate, is provided with a plurality of through holes.
Particularly, described through hole comprises six large through-holes and four small through hole, and six described large through-holes and four described small through hole are all evenly distributed on described solar term plate along the center of circle of described solar term plate, and symmetrical along the rotating shaft being arranged on described solar term plate.
Particularly, the internal diameter of described large trunnion is 36mm, and the internal diameter of described small venturi is 26mm, and the internal diameter of described large through-hole is 4mm, and the internal diameter of described small through hole is 2mm.
On solar term plate, be provided with two groups of through holes that vary in size, can block the mixed airflow of fuel oil and air, fuel particles splatter is pulverized; When mixed airflow passes through solar term sheet, produce eddy current air-flow; When air-flow is by different pore size simultaneously, produce different pressures, mixed gas, from high pressure to the lateral communication of low pressure place, makes its mixing more even.
The beneficial effects of the utility model are:
The fuel economizer suction tude of the utility model double-type eddy current blended fuel oil and air increases the vacuum ratio of fuel oil and air mixing place by twin-choke, fuel-oil atmozation quality is improved, by being provided with the solar term plate of a plurality of through holes, make mixed gas produce eddy current air-flow simultaneously, make its mixing more even.
Accompanying drawing explanation
Fig. 1 is the structural representation of the fuel economizer suction tude of the utility model double-type eddy current blended fuel oil and air, there is shown its internal structure;
Fig. 2 is the structural representation of solar term plate described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As depicted in figs. 1 and 2, the fuel economizer suction tude of the utility model double-type eddy current blended fuel oil and air, comprise small venturi 1, large trunnion 2 and jet pipe 3, the oil outlet end of jet pipe 3 is communicated with small venturi 1, the lower end of small venturi 1 is arranged in the upper end of large trunnion 2, and be provided with gap between the large inwall of trunnion 2 and the outer wall of small venturi 1, on gap, be provided with air conduit 4, the lower end of large trunnion 2 is provided with rotatable circular corrosion protection rubber solar term plate 5, on solar term plate 5, be provided with six large through-holes 7 and four small through hole 8, six large through-holes 7 and four small through hole 8 are all evenly distributed on solar term plate 5 along the center of circle of solar term plate 5, and symmetrical along the rotating shaft being arranged on solar term plate 5, the internal diameter of large trunnion 2 is 36mm, the internal diameter of small venturi 1 is 26mm, the internal diameter of large through-hole 7 is 4mm, the internal diameter of small through hole 8 is 2mm.
The working principle of the fuel economizer suction tude of the utility model double-type eddy current blended fuel oil and air is as follows:
By jet pipe 3, float chamber and small venturi 1 are connected, when fuel economizer is worked, when identical air inflow, small venturi 1 is with respect to common trunnion, the degree of vacuum of jet pipe 3 outlet end is larger, the relative flowing velocity of fuel oil and air increases, fuel oil reduces from the particle of oil nozzle ejection, the quality of atomization improves, and then pass through air conduit 4 to the interior conveying air of large trunnion 2, the higher mixed gas of atomization quality is further mixed with air, reduce the fuel oil ratio in mixed gas, mixed gas flow to solar term plate 5 again, on solar term plate 5, be provided with two groups of through holes that vary in size, can block the mixed airflow of fuel oil and air, fuel particles splatter is pulverized, when mixed airflow passes through solar term sheet, produce eddy current air-flow, further promote the condensation rate of fuel oil, when air-flow is by different pore size simultaneously, produce different pressures, make mixed gas from high pressure to the lateral communication of low pressure place, make its mixing more even.
