Description

Pulse type high-flow injection device

Technical Field

The invention relates to the technical field of water jet, in particular to a pulse type high-flow injection device.

Background

The water jet technology is a new material removing technology, and is widely applied to various fields of cleaning, manufacturing, processing, mining and the like due to the advantages of simple process, no dust, no spark, low noise and the like. In practical application, when the jet medium is kept unchanged, the water jet mainly comprises three types, namely continuous jet, pulse jet and cavitation jet. The pulse water jet has stronger impact energy because of continuously generating water hammer pressure in the jet process, has material destructive power obviously superior to that of continuous jet, and has wide application prospect.

According to the generation mode of the pulse water jet, the pulse water jet can be divided into a self-excited type and a separately excited type. Due to the fact that the self-excited pulse water jet is complex in research mechanism, the generated pulse oscillation frequency is difficult to adjust, and the self-excited pulse water jet is large in limitation on occasions needing certain specific water jet frequencies. The separately excited pulsed water jet can automatically adjust the pulse impact frequency of the water jet through external intervention, and can meet the pulse jet environment under different frequency requirements. Separately excited pulsed water jet can be classified into mechanical block type, extrusion type, explosion type, impact type and other generation modes according to the generation mechanism. The explosive type and impact type pulse water jet generation modes aim to generate single or few jet pulses, continuous and controllable work cannot be achieved, and the method is rarely applied to engineering practice. At present, the pulse jet generation modes applied to engineering practice and experimental exploration are mostly mechanical cut-off type and extrusion type. The extrusion type pulse jet flow generation mode has wide application prospect in engineering practice due to the characteristic of high energy utilization rate.

Extrusion formula pulse jet equipment single injection liquid volume is less among the prior art, and the pressure of spraying mainly depends on water pressure, and the pressure of spouting water can't be adjusted, can't adapt to multiple injection pressure operational environment's demand, needs to prepare large-scale supercharging equipment to water pressure boost, and is heavier and difficult regulation.
