Description
Technical field:
The utility model relates to a kind of teaching aid, especially a kind of portable fluid mechanical test case.
Background technology:
Along with the required knowledge of current university students is more and more abundanter, and the continuous renewal of scientific theory is replaced, and light easy experimental box becomes one of indispensable instrument on classroom.Fluid mechanics as the stronger course of a theoretical property, a lot of phenomenon or concept more difficult be familiar with by learner and understand.Meanwhile, hydrodynamic calculations equipment sold on the market at present, often all causes this subject of fluid mechanics because volume is too huge, can not for everybody shows all kinds of phenomenon and concept on classroom.
Utility model content:
The utility model object is deficiency in order to solve above-mentioned technology and provides a kind of portable fluid mechanical test case, this portable fluid Experiments of Machanics case, there is the advantages such as easy to carry, simple to operate and observe phenomena convenience, can use as assistant teaching aid on classroom.
In order to solve the problem, the utility model solves the technical scheme that its technical matters adopts: a kind of portable fluid mechanical test case, is characterized in that: it is made up of upper bush, lower sleeve, instrument cases, variable valve, joint, flowmeter, organic glass straight tube, connecting hose, the first submersible pump, the second submersible pump, the first switch and second switch.Described upper bush and lower sleeve are polypropylene board, and upper bush and lower sleeve can be nested and connect and compose chamber; The first described submersible pump is connected with organic glass straight tube with connecting hose by joint; The second described submersible pump is connected with organic glass straight tube with connecting hose by joint; The first described switch is connected with the first submersible pump by wire, controls the duty of the first submersible pump; Described second switch is connected with the second submersible pump by wire, controls the duty of the second submersible pump; Described flowmeter is connected with organic glass straight tube with connecting hose by joint; Described variable valve is connected with flowmeter with connecting hose by joint, the flow velocity of the straight liquid in pipe of variable valve adjustable organic glass.
The beneficial effects of the utility model are: this portable fluid Experiments of Machanics case, have the advantages such as easy to carry, simple to operate and observe phenomena convenience, can use on classroom as assistant teaching aid.
Accompanying drawing illustrates:
In order to the technical scheme that the utility model is implemented more clearly is described, illustrates below in conjunction with accompanying drawing and with embodiment, the utility model to be further illustrated.

Wherein, 1-upper bush, 2-lower sleeve, 3-instrument cases, 4-variable valve, 5-joint, 6-flowmeter, 7-organic glass straight tube, 8-connecting hose, 9-first submersible pump, 10-second submersible pump, 11-first switch, 12-second switch.
Embodiment:
In the first embodiment shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, a kind of portable fluid mechanical test case, is characterized in that: it is made up of upper bush, lower sleeve, instrument cases, variable valve, joint, flowmeter, organic glass straight tube, connecting hose, the first submersible pump, the second submersible pump, the first switch and second switch.Described upper bush and lower sleeve are polypropylene board, and upper bush and lower sleeve can be nested and connect and compose chamber; The first described submersible pump is connected with organic glass straight tube with connecting hose by joint; The second described submersible pump is connected with organic glass straight tube with connecting hose by joint; The first described switch is connected with the first submersible pump by wire, controls the duty of the first submersible pump; Described second switch is connected with the second submersible pump by wire, controls the duty of the second submersible pump; Described flowmeter is connected with organic glass straight tube with connecting hose by joint; Described variable valve is connected with flowmeter with connecting hose by joint, the flow velocity of the straight liquid in pipe of variable valve adjustable organic glass.
In the second embodiment shown in Fig. 1, Fig. 2, Fig. 5, when if desired testing on classroom, take out the utility model, detach upper bush and lower sleeve, and colourless water is injected into upper bush, injecting lower sleeve by dripping the water having red ink, respectively the first submersible pump and the second submersible pump being positioned in the upper bush and lower sleeve being marked with liquid simultaneously.At this moment open the first switch, utilize colourless water by organic glass straight tube air discharge, when in organic glass straight tube without closing the first switch during air; Open second switch after closing the first switch, at this moment observe the fluidised form of organic glass straight tube red liquid, and utilize flowmeter to read the flow velocity of now red liquid; Regulated the flow velocity of red liquid by variable valve, observe the change of flow state of organic glass straight tube red liquid, and utilize flowmeter to read the flow velocity of now red liquid.When after off-test, take out the first submersible pump and the second submersible pump, liquid is poured out, test unit is positioned over instrument cases, and instrument cases plug-in mounting is entered in the chamber be made up of upper bush, lower sleeve.
The utility model is easy to carry, simple operation and other advantages, have expressed the concept of the correlated knowledge point such as laminar flow, turbulent flow in fluid mechanics and laminar flow, relation between turbulent flow and flow rate of liquid intuitively.Can use as assistant teaching aid on classroom.
Above embodiment is only be described preferred implementation of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineering technical personnel in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
