Abstract
The invention belongs to materials processing technology, is related to a kind of material processing method using air pocket principle.The material processing method is based on system of processing, and the system of processing includes：Liquid input sources (1), air pocket segment occurred (2), machined material (3), liquid output (4), liquid input sources (1), air pocket segment occurred (2), machined material (3), the UNICOM basin of liquid output (4) one liquid communication of composition；Machined material (3) is in air pocket segment occurred (2), liquid has certain pressure and evaporating pressure in air pocket segment occurred (2), when flow rate of liquid exceedes certain limit, produce air pocket, appropriate cavitation impacts power will carry out configuration to machined material (3) or mechanical characteristic is transformed, so as to realize processing purpose.
Description
Technical field
The invention belongs to materials processing technology, is related to a kind of material processing method using air pocket principle.
Background technology
Air pocket is a common liquid phenomenon, allows pipeline damage, quant breakage etc. to have many destructive power, still
Past formula in fact is:
Wherein C air pockets discriminant coefficient, PrReference pressure, PvLiquid evaporation pressure, ρ fluid densities, v flow rate of liquid, if C
Air pocket will be produced much smaller than 1, when C will likely not produce much larger than 1 air pocket.
The 22 days June of 2017, Zhao Pan, Akihito Kiyama et al. provide acceleration and cavitation erosion by research
Relation is published in《Proceedings of the National Academy of Sciences》, its discrimination formula is：
Wherein, Ca air pockets discriminant coefficient, a acceleration, h liquid heights.There is no air pocket generation when Ca is more than 1, when Ca is small
It is to have air pocket generation in 1, may know that by above formula ought be more than appropriate acceleration, it is possible to air pocket occurs.
Air pocket has powerful destructive power, but we can be carried out using its powerful active force to material to material
The special processing such as processing, this processing relevant explosive has its security, feature of environmental protection etc., and can carry out at low temperature, is
A kind of brand-new processing method.
The content of the invention
The present invention seeks to：A kind of active force powerful using air pocket is provided and the destructiveness to material adds to material
The method of work.
The technical scheme is that：A kind of material processing method using air pocket principle, the material processing method base
In system of processing, the system of processing includes：Liquid input sources 1, air pocket segment occurred 2, machined material 3, liquid output 4, liquid
Body input source 1, air pocket segment occurred 2, machined material 3, the UNICOM basin of one liquid communication of composition of liquid output 4；It is processed
Material 3 is in air pocket segment occurred 2, and liquid has certain pressure and evaporating pressure in air pocket segment occurred 2, when flow rate of liquid exceedes necessarily
During scope, by formula (1) there may be air pocket, appropriate cavitation impacts power will carry out configuration to machined material 3 or mechanics is special
Property is transformed, so as to realize processing purpose.
The beneficial effects of the invention are as follows：The present invention can be added using it to the powerful active force of material to material
The special processing such as work, this processing relevant explosive has its security, feature of environmental protection etc., and can carry out at normal temperatures, is one
The brand-new processing method of kind.
Brief description of the drawings
Fig. 1 is system schematic of the present invention using the material processing method of air pocket principle；
Wherein, 1- liquid input sources, 2- air pockets segment occurred, 3- machined materials, the output of 4- liquid.
Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings.
Referring to Fig. 1, liquid input sources 1 are water under high pressure, air pocket segment occurred 2, machined material 3, liquid 4 low pressure water structures of output
Into the UNICOM basin of a liquid communication, machined material 3, such as glass etc. are in air pocket segment occurred 2, and liquid occurs in air pocket
Section 2 has certain pressure and evaporating pressure, when flow rate of liquid exceedes certain limit, by formula (1) there may be air pocket, suitably
Cavitation impacts power will carry out configuration to machined material 3 or mechanical characteristic is transformed, for example is broken into fritter, so as to realize processing
Purpose.
Claims (1)
1. a kind of material processing method using air pocket principle, it is characterized in that：The material processing method is based on system of processing, institute
Stating system of processing includes：Liquid input sources (1), air pocket segment occurred (2), machined material (3), liquid output (4), liquid input
Source (1), air pocket segment occurred (2), machined material (3), the UNICOM basin of liquid output (4) one liquid communication of composition；Added
Work material (3) is in air pocket segment occurred (2), and liquid has pressure and evaporating pressure in air pocket segment occurred (2), when flow rate of liquid surpasses
When crossing certain limit, air pocket is produced, cavitation impacts power will carry out configuration to machined material (3) or mechanical characteristic is transformed,
So as to realize processing purpose.
