Abstract
The utility model relates to a self-circulation static pressure transmission automatic water pumping instrument used for the teaching of fluid mechanics. The utility model comprises a back valve which can seal a pressure tank upwards and supply water automatically, a siphon which can seal the pressure tank downwards and discharge water automatically and a self-circulation water supply system. The teaching experiments, such as the theory of static-pressure spectacle, siphonage, etc. can be completed. The utility model has the advantages of automatic continuous experiments to and fro, high delivery lift, big flow quantity, spectacular phenomenon, beautiful appearance, good direct-viewing performance and excellent teaching effect, and can be used for the course teaching experiments of the engineering fluid mechanics in colleges for professional training.
Description
The invention belongs to teaching and experiment equipment.
The Hydrostatic Transfer Device phenomenon claims " static pressure wonder " again.The Hydrostatic Transfer Device experimental provision is the crucial instruments used for education of a class that carry out the aspect researchs such as energy conversion of hydrostatic pressure transmission characteristic, fluid.Existing this quasi-instrument is only by the upper and lower sealing load water tank 3 and 9 in the accompanying drawing, upper and lower header tank 4 and 12 and parts such as downcomer 8, snorkel 7 constitute.Its advantage is can clear demonstration Hydrostatic Transfer Device phenomenon.Its course of work is: the water in the upper condensate sump 4 flows into lower seal pressure water tank 9 through downcomer 8, case 9 middle water levels increase makes the gas compression, surface pressure increases, pass to sealing load water tank 3 through snorkel 7 equipressures, hydraulic pressure in the case 3 is raise, and water body just sprays through sparge pipe 2 and raises eminence in the case.Its shortcoming is: when water body in the last sealing load water tank 3 has sprayed or after lower seal pressure water tank 9 middle water levels completely push up, test just Halfway Stopping, and must manually open the gag of water tank 3 and 9, bleed off the water in the case 9, give in the case 3 again and add water, and supply water by manually replenishing to upper condensate sump 4, finished these a series of manually-operateds after, can proceed experiment.
The utility model purpose is an installing self-loopa water supply installation in instrument, supply water so that can replenish to upper condensate sump 4 automatically, and the sealing load water tank 3 that can make progress automatically adds water and can make the 9 automatic drainings of lower seal pressure water tank, overcomes the manually-operated drawback of dependence.
The utility model main points are: be provided with the self-loopa water supply installation that is made of lower condensate sump 12, electric water pump 11, upper condensate sump 4 and outlet conduit 1 in the instrument; Last sealing load water tank 3 is connected with upper condensate sump 4 by reverse checkvalve 6 and corresponding valve road; Lower seal pressure water tank 9 is provided with U trap 5 and is connected with lower condensate sump 12.Reverse checkvalve 6 is made of the valve and the corresponding valve of the shape road of tapered piston formula or dull and stereotyped female cap formula, and this valve cuts out when last sealing load water tank 3 internal pressures are higher than upper condensate sump 4 pressure, opens when being lower than.U trap 5 entrance points insert and near the bottom of lower seal pressure water tank 9, endpiece is lower than the entrance point position, and the U trap top is lower than and near the peak level of upper condensate sump 4.Crossing water system all adopts transparent organic glass to make.
The Hydrostatic Transfer Device of this instrument is tested automatic principle of work as shown in drawings.Now specify in conjunction with the accompanying drawings:
The water body that has in the upper condensate sump 4 of certain position potential energy flows into lower seal pressure water tanks 9 through downcomer 8, surperficial pressure in the case 9 is increased, and pass to sealing load water tank 3 through snorkel 7 equipressures, make the water body in the case 3 under surperficial pressure action, be ejected into eminence, realize the experiment purpose of pumping up water by Hydrostatic Transfer Device through lifting pipe and shower nozzle 2.After the water level in the case 9 completely pushed up, hydraulic pressure continued to rise, and flowed to making U trap 5 interior water levels completely push up and siphon takes place, and the water in the case 9 is entered lower condensate sump 12, and make the surperficial pressure in case 9 and the case 3 reduce.At this moment, because of the emptying substantially after a period of time, spray was raised of the water body in the last sealing load water tank 3, its surperficial pressure more reduces, and under the effect of water pressure of upper condensate sump 4, reverse checkvalve 6 is just opened automatically, and water flows into case 3 automatically from water tank 4.Water level in the case 4 decreases, and is lower than pipe 8 import, and the water body in the case 9 can not get external replenishing, and has arranged through U trap very soon.Then, under the effect of water pump 11, make the work of self-loopa water supply installation, water in the case 12 is supplied water through pipeline 1 feed-tank 4, the import that makes the water level in the water tank 4 raise gradually and flood pipe 8, so for the second time the Hydrostatic Transfer Device phenomenon of pumping up water repeats beginning again, so go round and begin again, formed " static pressure wonder " experimentation that the self-circulation type Hydrostatic Transfer Device is pumped up water automatically.
The utility model is manufactured experimently into sample in the laboratory, and except that water pump 11 and electric panel room, all members of experimental system are all made of transparent organic glass.Test findings shows that when upper and lower sealing load water tank discrepancy in elevation 40cm was above, the water spray lift was higher than 30cm, and whole reciprocal experimentation is automatic, coordination, continuous.The model machine volume is 70 * 15 * 80 (cm)
3, power consumption is 70W.Can clearly observe the energy conversion relation between Hydrostatic Transfer Device phenomenon, water spray height and the drop of " static pressure wonder " and the multinomial experiments such as occurrence condition of siphon in the experiment.
The advantage of this self-loopa Hydrostatic Transfer Device water pumping instrument is:
1. self-loopa is supplied water, can automatic reciprocating property be tested continuously, frees the trouble of artificial plumbing fully.
2. the amount of pumping up water is big, and the fountain magnificence is compared with former Hydrostatic Transfer Device experiment instrument with volume, and the amount of pumping up water can increase more than ten times.Because after the originally the sort of instrument amount of pumping up water increases, the number of times of artificial plumbing just increases greatly, reduces manually-operated number of times so have to reduce flow.
3. organization plan of this instrument and principle have engineering practical application meaning, for example, and purposes such as mountain area water lift.
4. the small and exquisite visuality attractive in appearance, transparent of external form is good, and experiential function is complete, very suitable teaching demand.
In the education experiment of the engineering fluid mechanics of specialties such as the present invention can be widely used in greatly, the aviation of special secondary school universities and colleges, water conservancy, machinery, chemical industry, building, metallurgy, traffic, environmental protection, bioengineering, food, medical science.
