Abstract
A kind of demonstration model for teaching of air pumping.It by No. 1, tank, No. 2, tank, water pump, tensimeter, liquid flowmeter, U-tube, enter tracheae and oral siphon forms, this utility model can simulate oil reservoir by water pump to water filling in oral siphon, change the gaseous tension passed into into tracheae, the water in No. 1, tank is made to enter in No. 2, tank by U-tube, the registration of recording manometer and liquid flowmeter, carrys out the relation of simulated injection different pressures gas and rate of flow of fluid.This model is convenient to be observed, and structure is simple and clear, is very applicable to teaching demonstration.
Description
Technical field
The utility model relates to a kind of model, the demonstration model for teaching of particularly a kind of air pumping.
Background technology
Various demonstration model for teaching brings a lot of convenience to student, and student can be helped to understand various phenomenon.But a lot of teaching mode is still directly perceived not.Therefore, for air pumping phenomenon, the demonstration model for teaching that design can show a kind of air pumping of the relation of injecting gas pressure and rate of flow of fluid intuitively seems necessary.
Summary of the invention
For the problems referred to above, the utility model provides a kind of demonstration model for teaching of air pumping, and this modular concept is simple, learns injecting gas pressure and rate of flow of fluid relation by observation tensimeter and liquid flowmeter registration.
The utility model solves the technical scheme that its technical matters adopts: it by No. 1, tank, No. 2, tank, water pump, tensimeter, liquid flowmeter, U-tube, enter tracheae and oral siphon forms, enter tracheae and be connected to tank No. 1 upper left quarter, tensimeter is arranged on into tracheae centre position, oral siphon is connected to tank No. 1 lower left quarter, water pump is arranged on inlet orifice medium position, No. 1, U-tube left end connection water channel, No. 2, right-hand member connection water channel, liquid flowmeter is arranged on U-tube inside.
The beneficial effects of the utility model are, type can simulate oil reservoir by water pump to water filling in oral siphon, change the gaseous tension passed into into tracheae, water in No. 1, tank is made to enter No. 2, tank by U-tube, the registration of recording manometer and liquid flowmeter, carrys out the relation of simulated injection different pressures gas and rate of flow of fluid.This device is convenient to be observed, and structure is simple and clear, is very applicable to teaching demonstration.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
In Fig. 1,1. tensimeter, 2. water pump, 3. liquid flowmeter, 4.U type pipe, 5. No. 1, tank, 6. No. 2, tank, 7. enters tracheae, 8. oral siphon.
Embodiment
The utility model by tensimeter (1), water pump (2), liquid flowmeter (3), U-tube (4), tank No. 1 No. 2, (5) tank (6), enter tracheae (7) and oral siphon (8) forms.In No. 1, tank (5), water is injected via oral siphon (8) by water pump (2), require that the height of water did not have U-tube (4) lower end, switch off the pump (2), to entering tracheae (7) interior injecting gas, the registration of now tensimeter (1) and liquid flowmeter (3) is recorded when liquid flowmeter (3) can just be passed to U-tube (4) in the water top of tank No. 1 (5) by the gaseous tension injected, by in the unit interval to entering the gas injecting different pressures in tracheae (7), the water in No. 1, tank (5) is allowed to flow in No. 2, tank (6) by U-tube (4), recording manometer (1) and liquid flowmeter (3) registration, injecting gas pressure and rate of flow of fluid relation during discussion air pumping, the utility model is convenient to be observed, structure is simple and clear, very be applicable to teaching demonstration.
