Description
Technical field
The present invention relates to Hydrodynamic Cavitation Technology field, particularly a kind of multifactor water hole cavitation experimental provision.
Background technology
Occur non-stationary cavity in liquid and indicate the nascent of cavitation in liquid, once there is cavitation in liquid, will break
The continuity of bad liquid, makes the hydrodynamic characterisitic of liquid motion change, and cavitation corrosion, generation cavitation noise are induced in solid wall surface
And possible excited vibrational etc..At present, being related to the field of cavitation phenomenon mainly has：High performance airscrew, high-speed torpedo, high speed submarine,
Water pump, the hydraulic turbine, hydraulic outlet works etc..For a long time, the consequence brought due to cavitation corrosion is all than more serious, so research is empty
The range of change, depth are all gradually increasing.
At this stage, the experimental facilities of Investigation of Cavitation Bubble Collapse mainly has：Circulating water tunnel, decompression cabinet, Venturi tube, electric spark are empty
Change and occur equipment etc..In this several equipment, although the research starting of circulating water tunnel is more early, so far, only pressure-adjustable
The circulating water tunnel without table, pressure-adjustable have this two class of the circulating water tunnel of table.The factor of influence cavitation compares
It is many, but this two class is for pressure this factor design, although and its is complicated, and operating process is cumbersome, but function compares piece
Face.Meanwhile, liquid stream needs to overcome substantial amounts of frictional resistance in cyclic process, causes equipment not save.
Therefore, it is badly in need of a kind of simple in construction, energy- and time-economizing, the multifactor water hole cavitation experiment dress with stronger applicability
Put.
The content of the invention
The present invention is intended to provide a kind of multifactor water hole cavitation experimental provision, for solving present in circulating water tunnel at this stage
It is complicated, operating process is cumbersome, function is simple, energy charge when, the series of problems such as applicability is poor.
The technical solution adopted for the present invention to solve the technical problems is：
This multifactor water hole cavitation experimental provision by visual Venturi tube, source of the gas, tracheae, gas core shower nozzle, enter liquid case, list
To pump, feed tube, two-way pump, switch, liquid outlet tank, drain pipe, water conservancy diversion leaf, pressure gauge, flowmeter composition.Four gas core shower nozzles are equal

To pump；Visual Venturi tube upstream line corner is provided with two water conservancy diversion leaves.
Advantages of the present invention：
The present apparatus can study the how many influences pair cavitation of air content provided with four gas core shower nozzles；There is switch on gas core shower nozzle,
Regulation switches on degree and can adjust the air inflow of each gas core shower nozzle and the turbulent extent of fluid, for study air content or
Influence of the turbulent extent to cavitation；Enter in liquid case and add liquid of different nature, liquid stream viscosity, polymer etc. can be studied to cavitation
Influence.The equipment is although simple in construction, simple to operate, but the cavitation influence factor that can be studied is more.In visual Venturi tube
Outbound pipeline corner can reduce the energy loss of upstream liquid stream on the corner, device is more saved provided with two water conservancy diversion leaves.Downstream
Liquid stream can be stood in liquid outlet tank after, be pumped into liquid case, recycled with two-way pump, reduced the waste of water resource, and make dress
Put clean-up performance higher.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the present apparatus.
Fig. 2 is sectional view at gas core shower nozzle.
In figure：Visual Venturi tube 1, source of the gas 2, tracheae 3, gas core shower nozzle 4, enter liquid case 5, it is one-way pump 6, feed tube 7, two-way
Pump 8, switch 9, liquid outlet tank 10, drain pipe 11, water conservancy diversion leaf 12, pressure gauge 13, flowmeter 14.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated：
This multifactor water hole cavitation experimental provision is by visual Venturi tube 1, source of the gas 2, tracheae 3, gas core shower nozzle 4, feed liquor
Case 5, one-way pump 6, feed tube 7, two-way pump 8, switch 9, liquid outlet tank 10, drain pipe 11, water conservancy diversion leaf 12, pressure gauge 13, flowmeter
14 compositions.Four gas core shower nozzles 4 are evenly distributed on the upstream tube wall of visual Venturi tube 1, and gas core shower nozzle 4 is provided with switch 9-
3—9-6；Enter and two-way pump 8 is installed between liquid case 5 and liquid outlet tank 10；The visual upstream line corner of Venturi tube 1 is provided with two
Water conservancy diversion leaf 12.
During work, start after one-way pump 6, since liquid flow entering liquid case 5, then flows sequentially through one-way pump 6, feed tube
7th, water conservancy diversion leaf 12, pressure gauge 13, flowmeter 14, visual Venturi tube 1, finally return to liquid outlet tank 10 from drain pipe 11.
When opening switch 9-3-9-6 on gas core shower nozzle 4, while regulation four switchs opening degrees, and keep adjusting every time
Four switch opening degrees are identical after section, and gas flows out from source of the gas 2, flows through tracheae 3, gas core shower nozzle 4, and sprayed by gas core shower nozzle 4
Gas core is formed afterwards, is finally dissolved in liquid.In such cases, available for the how many influences pair cavitation of air content in research liquid stream.
Two or more opening degrees in switch 9-3-9-6 on opening gas core shower nozzle 4, but this four switches
It is different, or wherein some or the multiple switch of this four switches are only opened, the turbulent extent for ultimately resulting in liquid stream is different.
In such cases, the influence available for research turbulent extent to cavitation.
One or more working solutions are added toward entering in liquid case 5, liquid, polymerization thing liquid is such as viscosified, it is viscous available for research respectively
Influence of the one or more factors such as degree or polymer to cavitation.
The pump pressure of one-way pump 6 is adjusted, pump pressure is different, then the pressure of liquid stream, flow can also change therewith, and corresponding data can
Measured from pressure gauge 13, flowmeter 14, now the influence available for research pressure, flow to cavitation.
Work after a period of time, the liquid entered in liquid case 5 can be gradually decreased, and the liquid in liquid outlet tank 10 can gradually increase
Plus, liquid can stand a period of time in liquid outlet tank 10, two-way pump 8 and switch 9-1,9-2 then be opened, by impure few liquid
Body is pumped into liquid case 5 from liquid outlet tank 10, for recycling., can be feed liquor when experiment terminates, and all liquid no longer needs
Remaining liquid is pumped into liquid outlet tank 10 and disposed together in case 5.
The present apparatus can not only study the how many influences pair cavitation of air content, it can also be used to study provided with four gas core shower nozzles 4
Influence of the fluidised form to cavitation.Enter and liquid of different nature is added in liquid case 5, liquid stream viscosity, polymer etc. can be studied to cavitation
Influence.The visual upstream line corner of Venturi tube 1 can reduce the energy of upstream liquid stream on the corner provided with two water conservancy diversion leaves 12
Loss, device is more saved.After the liquid stream in downstream can be stood in liquid outlet tank 10, it is pumped into two-way pump into liquid case 5, circulation profit
With, the waste of reduction water resource, and make device clean-up performance higher., can be when experiment terminates, and all liquid no longer needs
Enter remaining liquid in liquid case 5 and be pumped into liquid outlet tank 10 and dispose together.
This multifactor water hole cavitation experimental provision is simple in construction, energy- and time-economizing, with stronger applicability.
