Line, stagger.Liquid in the gap of right angle tooth 7 and tilted teeth 9 by two dental structures high-pressure extrusion active force, static pressure is
Highest part in system.When two conllinear teeth stagger completely, when the first groove 8, the second groove 10 are completely conllinear, groove area shape
Into larger low-pressure area, liquid abruptly enters low-pressure area from extruding higher-pressure region, and static pressure reduction, cavitation is with the largest potentiality.Work as static pressure
When value is less than the saturated vapour pressure of liquid at such a temperature, occur cavitation phenomenon, it is conllinear in oblique tooth rotor 5, straight tooth rotor 6 two
The first groove 8, b meanings region in cavitation bubble, such as Fig. 4 is produced between the second groove 10.
3rd, in oblique tooth rotor 5, the straight relative rotational motion of tooth rotor 6, right angle tooth 7 is periodically common with tilted teeth 9
Line, stagger.Liquid in the gap of right angle tooth 7 and tilted teeth 9 by two dental structures high-pressure extrusion active force.In addition, high
Two rotors of speed rotation form the shear action to liquid because viscous effect drives liquid to relatively rotate again.In two teeth
Conllinear to during staggering completely, the geometry formation Venturi tube structure of right angle tooth 7 and tilted teeth 9 from starting.In shearing
Under power and the collective effect of Venturi tube structure, larger low-pressure area is formed between two conllinear teeth, when static pressure is less than liquid
During saturated vapour pressure at such a temperature, occur cavitation phenomenon, oblique tooth rotor 5,6 two conllinear diastema of straight tooth rotor it
Between produce in cavitation bubble, such as Fig. 4 c meanings region.
From above-mentioned, cavitation occurs mainly in three regions.First, between oblique tooth rotor 5, straight tooth rotor 6 and housing 3
Gap, cavitation is produced in the rotation most leading edge of right angle tooth 7 and tilted teeth 9；Second, the first groove 8, straight tooth when oblique tooth rotor 5 turn
When second groove 10 of son 6 is conllinear, cavitation can be produced between the groove of rotor；3rd, between oblique tooth rotor 5, the tooth of straight tooth rotor 6
Venturi space can occur cavitation.Oblique tooth rotor 5, straight tooth rotor 6 high-speed rotation under the driving of motor 4, cause pressure field
Quick change, so as to cause device, periodically pressure is reduced, and occurs violent cavitation phenomenon.
Described above is only the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, under the premise without departing from the principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
