Embodiment Construction
[0027] Below in conjunction with accompanying drawing, the present invention will be further described: Figure 1-2 As shown, the multi-functional self-vibration period deflection pulse jet generator is mainly composed of upper nozzle 1, adjusting ring 2, rolling bearing 3, baffle plate 4, rotor 5, abrasive conveying pipe 6, shell 7, oscillation cavity 8, lower nozzle 9 composition.
[0028] Such as image 3 As shown, the upper nozzle 1 is connected to the high-pressure water inlet pipe (not shown in the figure) through the external thread 12 at the end, and connected to the internal thread 15 in the ring of the adjustment ring 2 through the external thread 13 at the middle; the adjustment ring 2 The screw passes through the through hole 14 on the end face of the adjustment ring to connect with the left end threaded hole 24 of the oscillation cavity at the left end of the oscillation cavity 8 .
[0029] The rolling bearing 3 is fixed on the oscillating cavity 8 through inter...

The invention belongs to the field of high-pressure water jets, and in particular relates to a multifunctional self-vibration period deflection pulse jet generator which forms self-priming abrasives or air through self-excited oscillation. It is mainly composed of an upper nozzle, an adjusting ring, a rolling bearing, a baffle, a rotor, an abrasive conveying pipe, a casing, an oscillating cavity, a lower nozzle, and a high-pressure air conveying pipe; the upper nozzle is connected to the adjusting ring through threads; the adjusting ring, The baffle plate, the shell and the oscillation chamber are connected by screws, and the rolling bearing and the rotor are enclosed therein; the lower nozzle is connected with the oscillation chamber by screws. Its advantages are: using the characteristics of the self-excited oscillating pulse jet, through the periodic barrier of the rotor to the through hole on the shell and the wall of the oscillating cavity, the abrasive or air is periodically sucked into the cavity, resulting in periodic deflection of the jet, Then the strike effect and action range of the self-excited oscillating pulse jet are enhanced, and its application range is expanded.
Description
technical field [0001] The invention belongs to the field of high-pressure water jets, and in particular relates to a multifunctional self-vibration period deflection pulse jet generator which forms self-priming abrasives or air through self-excited oscillation. Background technique [0002] High-pressure water jet technology is a new type of technology developed in recent decades, widely used in coal, petroleum, mining, processing, manufacturing, military and other fields. Compared with other processing methods and methods, water jet is the only cold processing method, which has unique advantages in processing many materials, especially heat-sensitive materials. In high-pressure water jet, self-excited oscillating pulse jet is widely used because of its simple structure, low cost and good effect. [0003] The self-excited oscillating pulse jet is a new type of high-efficiency pulse jet developed by the theory of fluid resonance, elastohydrodynamics, hydroacoustics, and tra...
