Problems solved by technology

Since the post-mixed abrasive water jet cannot fully mix the abrasive with the high-speed flowing water, the transmission efficiency of the water medium to the abrasive is significantly reduced, so under the same energy consumption, the cutting ability of the post-mixed abrasive water jet is far lower Depth of cut with pre-mixed abrasive waterjet
Therefore, the research on pre-mixed abrasive water jet has become the focus of abrasive water jet research, but for a long time a key issue in the application of pre-mixed abrasive water jet is the control of the amount of abrasive

Abstract

The invention discloses an ultra-high pressure pre-mixed abrasive jet abrasive feed device for adjusting the amount of abrasive, which belongs to the technical field of abrasive water jets. It can realize that the abrasive is added from the abrasive inlet and then connected to the outlet of a high-pressure air source, and the pressure is adjusted to the pressure of the jet fluid. Connect the discharge port to the jet pipeline, start the speed-regulating motor, and drive the outer magnetic steel seat to rotate synchronously. The parallel direction of the outer magnetic steel and the inner magnetic steel is N and S grades. The magnetic steel seat drives the feeding screw to rotate through the rotating shaft, and sends the abrasive to the discharge port. The feeding amount per unit time is determined by the rotation speed and the lead of the feeding screw. Therefore, adjusting the speed of the speed-regulating motor can quantitatively adjust the abrasive in the jet fluid. The ratio in the medium can realize the precise control of the amount of abrasive in the pre-mixed abrasive water jet. In addition, a grinding aid component is set to assist the mixing of abrasive and water to improve the uniform mixing effect, and to fully accelerate the abrasive in the water, so that it has higher kinetic energy. Thereby improving the working effect.

Description

technical field [0001] The invention relates to the field of abrasive water jet technology, and more specifically relates to an ultra-high pressure pre-mixed abrasive jet abrasive feed device for adjusting the amount of abrasive. Background technique [0002] Abrasive water jet is a kind of high pressure water jet. It uses water as the medium and uses a high-pressure generating device to obtain huge energy. The abrasive particles are accelerated by the high-pressure water jet, and are added to the high-pressure water jet through the feeding and mixing device to form a mixed jet. Cutting process. [0003] The abrasive water jet system is mainly composed of abrasive tank, high-pressure pump station, high-pressure water nozzle and abrasive nozzle. Abrasive particles have edges and corners, and their mass is larger than that of water. They are distributed in the water jet under the same high-pressure condition, and the impact grinding force of the abrasive water jet on the obj...
