Embodiment Construction
[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0032] see Figure 1-13 , the embodiment of the present invention discloses an internal swirl cross-hole injector, comprising: a main body 1, the main body 1 has a first cavity 2, a second cavity 3, a first channel 4 and a second channel 5, the first cavity The body 2 is arranged on the first end face of the body 1, the first cavity 2 is a blind hole arranged on the axis of the body 1, the second cavity 3 is sleeved on the periphery o...

The invention discloses an internal rotational flow cross hole ejector which comprises a body, the body is provided with a first cavity, a second cavity, a first channel and a second channel, the first cavity is formed in the first end face of the body and is a blind hole formed in the axis of the body, the second cavity is arranged on the periphery of the first cavity in a sleeving mode, and the first cavity and the second cavity are coaxially arranged; the bottom end of the second cavity is a blind end, the first cavity and the second cavity are communicated through a first channel, the second channel is arranged on the second end face of the body, and the second channel is communicated with the first cavity. The jet device has the beneficial effects that two kinds of fluid are introduced into the first cavity and the second cavity respectively, then turbulence disturbance in the jet holes of the jet device can be enhanced, better mixing and jetting characteristics are obtained, meanwhile, the high-disturbance jet device enhances the solution atomization effect, the spray particle size is reduced by 25% or above under the same jetting pressure, and the spraying efficiency is improved. And the fluid evaporation, atomization and mixing efficiency is improved by more than 50%.
Description
technical field [0001] The invention relates to the technical field of injectors, and more particularly to an internal swirl cross-hole injector. Background technique [0002] At present, the ejector is used in many kinds of spraying, spraying, oil spraying, sandblasting, spraying and other equipment, and plays an important role, and is a very critical component that affects the effect of fluid atomization. Injectors are widely used in the industry, but still have the following shortcomings: [0003] For example: First, in the field of internal combustion engine in-cylinder fuel atomization and injection, the atomization effect of fuel has a great influence on the fuel combustion effect, which directly affects the emission of pollutants. With the increasingly stringent national emission regulations, The requirements for fuel injectors are becoming more and more stringent; second, in order to reduce NOx emissions in the engine after-treatment system, a reducing agent is inje...
