Description
Technical field
The utility model relates to underwater cavitating jet nozzle, is specifically related to a kind of pre-rotation cavitation jet nozzle.
Background technology
For the cleaning of immersed body, can adopt underwater cavitating fluidics, utilize cavitation effect, use lower hydraulic pressure can produce good cleaning performance.Can utilize the nozzle arrangements that produces cavitation to have the type of streaming (center build nozzle, rotating vane type nozzle), shearing-type (simple dihedral, contraction cast, trumpet type etc.), oscillation mode (organ pipe self-excited oscillating type, Helmholtz self-excited oscillating type etc.) etc., the existing nozzle made from above-mentioned principle is all taper (cylindricality) jet nozzle, be that its nozzle cross-section is circle, jet becomes taper (column).Existing nozzle just utilizes cavitation effect to produce cavitation bubble, the effects such as the physics being produced by cavitation bubble, chemistry act on surface to be cleaned and reach cleaning object, generally will by increase rotating mechanism (use rotary seal structure) or repeatedly washing and cleaning operation reach better cleaning performance.In sum, an existing nozzle research and utilization cavitation forms cavitation bubble and reaches cleaning object, if strengthen cleaning performance, need to increase nozzle exit pressure and flow, increased accordingly the work power of the assembling unit, security control in equipment voltage endurance capability, operating process has been had to requirements at the higher level simultaneously, both increased construction cost, also reduced ease for operation and security.
Utility model content
In view of this, the purpose of this utility model is for deficiency of the prior art, a kind of pre-rotation cavitation jet nozzle is provided, can under Same Efficieney power consumption, increase the cleaning performance of jet, or under identical cleaning performance, the requirement of minimizing to water flow pressure, flow, reduction work power demand, saves energy consumption, makes work progress environmental protection more, safe, convenient simultaneously.
For completing above-mentioned purpose, the technical solution adopted in the utility model is: pre-rotation cavitation jet nozzle, described jet expansion is provided with pre-rotation structure, and the cross section of described jet expansion and described pre-rotation structure is in-line, cross, any one in square.
Further, described pre-rotation structure is traversed whole nozzle body, from nozzle water inlet, is shaped as the non-cylindrical of circumgyration stretch in nozzle chamber, and its cross section is in-line, cross, any one in square.
Further, described nozzle water inlet is taper, by wide gradually narrow, to reduce water inlet turbulization, reduces energy consumption.
Further, described in-line, cross, square edge are provided with chamfering, and edge is provided with chamfering, and chamfering can increase the scattering angle of nozzle, increase the shear effect with current.
Compared with prior art, the utility model is in conjunction with abnormity outlet and the design of pre-rotation double structure, and its special-shaped shape is adjustable, and the degree of depth, length, the chamfering of abnormity are variable; Pre-rotation structure can utilize structural design to make water jet before ejaculation, produce cross torsion power, produce rotating vortex, increased the shear surface with environment current, increased shear action, produced simultaneously cross torsion masterpiece is used for being cleaned face, can greatly strengthen the cleaning performance of jet after comprehensive function under same power and water environment, saves energy consumption, reduction is to water flow pressure and traffic requirement, safer to operating personnel.
