Description
Technical field
The invention patent relates to instruments used for education, specially a kind of simple Hydromechanics experimental device.
Background technique
Hydrodynamics is the important content of middle school physics, to allow student to understand thoroughly and grasp hydromechanical science former
Reason, it is necessary to take action on one's own to test " Chinese language is read, and mathematics practices physics and chemistry and do it yourself one time "；But existing instrument demonstrating effect is very
Difference, especially student cannot do it yourself to make, can not practice and the innovation of training student well ability.
Summary of the invention
In order to solve the problems, such as existing instrument effect difference and be not easy to student to do it yourself to make, a kind of simple stream is provided
Mechanics experimental provision；
The invention patent is realized with following technical scheme；
A kind of simple Hydromechanics experimental device, including pedestal, the lower section device glass water tank of pedestal fill in glass water tank
Miniature immersible pump is set, while device drains plug；Submounts have bottom plate, the thick water pipe of bottom plate apparatus, thin conduit and medium water pipe,
Piece thin glass tube of device on each water pipe draws water level contour in substrate, there is connection water on the right side of thick water pipe
Pipe is connected to water storage cylinder, and water storage cylinder is connected with upper hose with miniature immersible pump.
Detailed description of the invention
Fig. 1 is the invention patent front plan view.
In figure：1, glass water tank；2, micro pump；3, power-line plug；4, upper hose；5, water storage cylinder；6, thick water pipe；7,
Medium water pipe；8, thin conduit；9, vertical glass tubes；10, water level contour；11, bottom plate；12, pedestal；13, plug is drained.14,
It pours water lid.
Specific embodiment
A kind of simple Hydromechanics experimental device is mainly characterized by including pedestal (12), the lower section device of pedestal (12)
Glass water tank (1), the inner device miniature immersible pump (2) of glass water tank (1), while device draining plug (13)；Pedestal (12) is above
Have bottom plate (11), the thick water pipe of device (6) on bottom plate (11), thin conduit (8) and medium water pipe (7), device one on each water pipe
The vertical thin glass tube of root (9) draws water level contour (10) in bottom plate (11) above, has connection water on the right side of thick water pipe (6)
Pipe is connected to water storage cylinder (5), and water storage cylinder (5) is connected with upper hose (4) with miniature immersible pump (2).
The invention patent using bernoulli principle design, be sent by upper hose and stored up by immersible pump by the water in glass water tank
Water drum, then thick water pipe, medium water pipe and thin conduit are flowed by water storage cylinder, thin conduit outlet is blocked with finger, three water pipes are full of
When water, for the inside water due to not flowing, pressure is equal, thus in three vertical glass tubes water level be it is identical, work as relieving
Finger water starts to flow, because the diameter of thickness water pipe and medium water pipe is different, volume is also different, so three water pipe water
Flowing velocity with regard to different, the water flowing in thin conduit is fastest so pressure is minimum, under atmospheric pressure, water level
That drops is minimum, and medium water pipe water level takes second place, and water flowing speed is most slow in thick water pipe, therefore the water level highest of vertical water pipe thereon.Again
Water outlet is blocked with finger, water level can be maintained on same contour again in three vertical water pipes.
The invention patent can make of waste, be convenient for student's manual fabrication, what thickness water pipe can be discarded with size
Syringe jacket is got up, and glass water tank can cut viscous, water storage cylinder beverage sky cylinder with cullet.Manufacture craft is simple, not only has new
Newness and science, and have good practicability.
Experimental method is as follows：
Opening lid (14) of pouring water is poured water in the glass water tank (1), and tank connects immersible pump to miniature immersible pump is flooded later
(2) power supply, immersible pump (2) start to work, water are continually pumped into water storage cylinder (5), flow into three following water pipes；Use hand
Finger is realized and is firmly fine into water pipe water outlet, enters vertical glass tubes (9) simultaneously after three water pipe water are full, due to three water pipes water not
Flowing, pressure is equal, so the water level in three vertical glass tubes is maintained at equal height；Decontroling finger makes in three water pipes
Water start to flow, since the flow velocity of water in three water pipes is different, so different pressure is generated, in the effect of external atmosphere pressure
Under, different height can be presented in water level in three vertical glass tubes；Water outlet is covered again, is tested repeatedly.It proves vividly
The faster pressure of flow velocity smaller fluid mechanics principle.In demonstration, in order to reinforce visuality, red ink can be added to allow in water
Water reddens.
