Problems solved by technology

However, there are some defects in the existing double-oil circuit pressure atomization fuel nozzles. The fuel injection in the main oil circuit is atomized first, and then mixed with air, so the quality of fuel and air mixing is not high, and the fuel in the auxiliary oil circuit only uses pressure mist The atomization quality is not high

Embodiment 1

[0032] see Figure 1-7 , according to an embodiment of the present invention, a dual-oil nozzle structure includes an oil supply pipe seat 1 and a nozzle seat 2, the oil supply pipe seat 1 is provided with a main oil pipe 3 and an auxiliary oil pipe 4, and the inside of the nozzle seat 2 A main oil passage mechanism 5 connected to the main oil pipe 3 is arranged, and an auxiliary oil passage mechanism 6 connected to the auxiliary oil pipe 4 is arranged inside the nozzle seat 2. The output end of the main oil passage mechanism 5 A radial swirler 7 and an axial swirler 8 are provided, a Rafal nozzle 9 is provided on the output end of the auxiliary oil passage mechanism 6, and the main oil passage mechanism 5 includes a An annular groove 10 near one end of the oil supply pipe seat 1 and arranged along the circumference of the nozzle seat 2, the annular groove 10 communicates with the main oil pipe 3 correspondingly, and the main oil pipe 10 is connected to the annular groove 10 ...

Embodiment 2

[0034] Such as Figure 3-4 As shown, the sealing mechanism includes a first cylinder 23 fixedly sleeved on the oil supply pipe seat 1 and a second cylinder 24 fixedly sleeved on the nozzle seat 2, the first cylinder The diameter of 23 is smaller than the diameter of the second cylinder 24, and the first cylinder 23 is inserted into the second cylinder 24, and the inner wall of the first cylinder 23 is pasted with a high temperature resistant first sealing ring 25, The nozzle seat 2 is inserted into the first cylinder 23, and the first sealing ring 25 wraps the outer surface of the nozzle seat 2, and the second sealing ring 26 is pasted on the inner wall of the second cylinder 24. The second sealing ring 26 wraps the outer surface of the first cylinder 23, the oil supply pipe seat 1 is fixedly provided with a third cylinder 27, and the inner wall of the third cylinder 27 is pasted with a third sealing ring 28, The second cylinder 24 is inserted into the third cylinder 27, and ...

Embodiment 3

[0037] Such as Figure 3-4 As shown, the anti-screw fall-off mechanism includes a fourth cylinder 29 fixedly sleeved on the oil supply pipe seat 1, and a fifth cylinder 30 is sleeved inside the fourth cylinder 29, and the fifth cylinder 30 is sleeved inside the fourth cylinder 29. The cylinder 30 is sleeved on the third cylinder 27 through a spring mechanism, the spring mechanism includes a spring 31, the inner wall of the fourth cylinder 29 is provided with a spring arrangement groove 32, and one end of the spring 31 is fixed on the The other end of the spring 31 is fixed on the fifth cylinder 30 .

Abstract

The invention discloses a double-oil-way nozzle structure which comprises an oil supply pipe seat and a nozzle seat, a main oil pipe and an auxiliary oil pipe are arranged in the oil supply pipe seat, a main oil way mechanism connected with the main oil pipe is arranged in the nozzle seat, an auxiliary oil way mechanism connected with the auxiliary oil pipe is arranged in the nozzle seat, and the main oil way mechanism and the auxiliary oil way mechanism are arranged in the nozzle seat. The output end of the main oil way mechanism is provided with a radial swirler and an axial swirler, and the output end of the auxiliary oil way mechanism is provided with a Laval nozzle. The beneficial effects are that the swirl plate is provided with the swirl hole used for allowing fuel oil to pass through and generating swirl, the fuel oil generates swirl so as to improve the atomization quality of the fuel oil of the auxiliary oil path, the whole auxiliary fuel oil is differentiated, the swirl effect of the fuel oil is better, ignition of a combustion chamber is more convenient, gas is pressurized by an air pump and enters through an air inlet channel, and the fuel oil atomization effect is improved. And the cyclone mechanism is matched, so that air entering the cyclone mechanism generates cyclone, and the ignition performance generated by subsequent air and fuel oil is better.

Description

technical field [0001] The invention relates to the field of oil path nozzles, in particular to a double oil path nozzle structure and a nozzle system thereof. Background technique [0002] In the combustion chamber of the engine, the fuel is injected into the combustion chamber through the fuel nozzle. In the design of the dual oil circuit fuel nozzle, the fuel injection of the auxiliary oil circuit is mainly used for the ignition of the combustion chamber, and the main oil circuit is used for heavy working conditions. fuel supply. In the traditional double oil circuit pressure atomization fuel nozzle, the atomization of fuel oil in the main and auxiliary oil circuits generates strong centrifugal force through high-speed swirling flow, thereby compressing the liquid film, gradually breaking the liquid film and forming small droplets. However, there are some defects in the existing double-oil circuit pressure atomization fuel nozzles. The fuel injection in the main oil circ...
