Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water jet system, and more particularly to a water jet injection booster.

[0002]

2. Description of the Related Art A conventional water jet jets high-pressure water directly, or jets water containing high-pressure water mixed with a cutting auxiliary material at high speed.

[0003]

SUMMARY OF THE INVENTION An object of the present invention is to provide a water jet having excellent performance by significantly enhancing the jetting force as compared with the conventional water jet.

[0004]

[Means for Solving the Problems] Injecting high-pressure water
A main body provided with an injection fine hole of about 1 mm, and a compressed air is ejected around the injection fine hole at the tip of the main body 0.5
An air supply body having a conical member for forming a vacuum space of about mm is fitted, an air supply pipe is connected to the air supply body 12, and a fumarolic slit is formed in a space communicating with the conical member and the air pipe to form an air supply pipe. Water jet injection intensifier with mixed cutting aid material.

[0005]

When compressed air is sent from the jet air gap 17 and high-pressure water is jetted from the jet fine hole 12, a vacuum space is generated and the water is jetted at 5 to 6 times the speed of sound, and cuts the material to be cut. . In addition, mix the cutting auxiliary material from the air intake of the air supply pipe,
The cutting power is further enhanced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference numeral 11 in the drawing is a rod-shaped main body having a through hole having a 0.1 mm injection fine hole 12 formed at the tip thereof and communicating with a pressure water supply source. Reference numeral 14 denotes an air supply body fitted to the tip of the main body 11, and is provided with a front plate 18 for closely adhering a pyramidal member 15 fitted to the main body 11 and forming a fusible slit 17 around the pyramidal member 15. In addition, an air supply pipe 19 for sending air is inserted into the injection slit 17 so that water coming out from the injection small holes 12 of the main body 11 which has become a vacuum space is pulled in a conical area in the air in the front 20 to form a vacuum. Therefore, the pressure is further increased there, and the fuel is injected at a speed 5 to 6 times the speed of sound.

[0007]

According to the present invention, when the jet holes of the water jet are set in the vacuum space, the air resistance becomes 0, and the jetted water is pulled by the vacuum and accelerated to generate the pulling vacuum of the pulling vacuum created in the air. In the conical area, it is accelerated to 3 to 6 times the speed of sound. It is possible to cut any object by mixing cutting aid material with this ultra high speed water.
