高压水射流两个主要特点决定了它的应用范围。 1、比能高,当机械工具只有几焦耳/厘米~3时,它却超超过500焦耳/厘米~3; 2、功率转移(1000千瓦/厘米~2)远远大于普通工具所允许的值(1千瓦/厘米~2)。这两个特点表明,高压水射流不仅能用来破碎大块物料,而且更确切地说它是一种特殊的采掘工具,能切割岩槽、凿岩,亦可作为破岩刀具的辅助工具。 (一)水射流切割岩槽如果我们让一束高压水射流在一块岩石上移动(为了不让能量在空气中损失太大,使喷嘴尽量接近岩石的表面,例如为1厘米),若压力足够大的话,那么,我们可以得到一个狭
Two main features of high pressure water jet determine its scope of application. 1, high specific energy, when the mechanical tools only a few joules / cm ~ 3, it exceeds 500 joules / cm ~ 3; 2, power transfer (1000 kW / cm ~ 2) is much larger than the value of ordinary tools (1 kW / cm ~ 2). These two characteristics show that high-pressure water jet can not only be used to crush large pieces of material, but rather it is a special extractive tool that can cut rock trenches and rock and can also be used as a tool for rock breaking tools. (A) water jet cutting rock groove If we let a bunch of high-pressure water jet on a rock (in order to prevent energy loss in the air too much, the nozzle as close as possible to the rock surface, for example, 1 cm), if the pressure is sufficient Big words, then, we can get a narrow
