Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0031] A pre-mixed abrasive water jet continuous operation system, such as figure 1 As shown, it includes a jet pump 2 and a high-pressure pump device 1 that outputs high-pressure water. The high-pressure pump device 1 is connected to the input end of the jet pump 2 through a high-pressure water pipeline 5, and the suction port 2-2 of the jet pump 2 is directly connected to Abrasive tank 3 is filled with abrasive material, and the output end of the jet pump 2 is connected to the abrasive jet nozzle 4 through the abrasive water jet pipeline 6 .

[0032]As long as the system ensures that the abrasive in the abrasive tank 3 is uninterrupted, the abrasive can be sucked quickly by using the entrainment effect of the jet pump 2 and the weight of the abrasive itself. After the abrasive is mixed with water, it will be pressurized and accelerated through the abr...

Abstract

The invention provides a pre-mixed abrasive water jet type continuous working system. The system comprises a jet pump, and a high pressure pump device for outputting high-pressure water, wherein the high pressure pump device is connected with the input end of the jet pump through a high-pressure water pipeline; an abrasive tank is connected to a material sucking port of the jet pump; the output end of the jet pump is connected with an abrasive jet nozzle through an abrasive water jet pipeline. The invention also provides a pre-mixed abrasive water jet type continuous working method. According to the system and the method, the abrasive can be quickly pumped and sucked under the entrapment effect of the jet pump as well as the weight effect of the abrasive; after being mixed with water, the abrasive is pressurized and accelerated through the abrasive jet nozzle, and then a pre-mixed abrasive water jet can be sprayed out; and the stable pre-mixed abrasive water jet can be formed on the premise that the abrasive in the abrasive tank for supplying the abrasive is continuously supplied. Therefore, the problem that the abrasive cannot be continuously supplied in the prior art can be solved.

Description

technical field [0001] The invention relates to the field of fluid machinery, in particular to a pre-mixed abrasive water jet continuous operation system and method. Background technique [0002] Abrasive water jet technology is a new technology developed in modern times, which is widely used in industrial cutting, rock excavation, surface cleaning and drilling. According to different feeding methods, abrasive water jets are divided into pre-mixed abrasive water jets and post-mixed abrasive water jets. Since the post-mixed abrasive water jet cannot fully mix the abrasive with the high-speed flowing water, the transmission efficiency of the aqueous medium to the abrasive is significantly reduced. Under the same energy consumption, the cutting depth of the post-mixed abrasive water jet can only It reaches half of the cutting depth of the pre-mixed abrasive waterjet, and in rock excavation, drilling, etc., due to the poor rock-breaking ability of the post-mixed abrasive waterj...
