Description
Technical field
This utility model is related to a kind of experiment survey meter device, and in particular to a kind of tester for viscosity factor.
Background technology
Various actual liquids have different degrees of viscosity.When liquid flows, parallel to each laminar flow of flow direction
Body speed is different from, that is, there is relative slip, then just have the generation of frictional force between the layers, and this frictional force just claims
For viscous force.It is oriented parallel to contact surface, and which is directly proportional less than gradient and contact area of speed greatly, and proportionality coefficient η is just
The referred to as coefficient of viscosity, it is to characterize the strong and weak important parameter of fluid viscosity, and its measurement is very important.
The coefficient of viscosity of measurement liquid has various methods, laboratory in colleges and universities's back warp frequently with falling ball method measure.It is existing
Some falling ball method analyzers include a base plate, and the pipe of one group of different-diameter, the axis and base plate of each pipe are provided with base plate
Vertically, there is air level indicating instrument horizontality on base plate, have two graduation mark of A, B on each pipe, and between two graduation marks
Distance it is equal, by experiment steel ball to be put into different tube center positions and falls, measure successively by groove A in each pipe,
The time of B, so as to the coefficient of viscosity of liquid is calculated by formula.
But, student is in experiment, it may appear that following problem：1st, due to being the centre bit that pipe is judged by naked eyes
Put, then steel ball is put in tweezers, error easily occur, particularly in the pipe of small diameter, bad of center
Hold, error ratio is larger.What the 2nd, experimental liquid was selected is the larger oil-based liquid of the coefficient of viscosity, by steel ball along tube wall is suctioned out when
Wait, the fluid of steel ball upper band is easily dripped on base plate, cause the bad cleaning of base plate, cleaning unclean.3rd, experiment stopwatch is single
Solely place, stopwatch leaves about after experiment often occurs in Jing, can not find, the problems such as stopwatch is broken.
Utility model content
The purpose of this utility model is to devise a kind of tester for viscosity factor for the problem in background technology, to solve
Certainly existing analyzer measures the problems such as inaccurate, base plate is not easily cleaned, thing leaves about.
The technical solution of the utility model：
A kind of tester for viscosity factor, including an experiment steel ball, a stopwatch, a base plate be different with a group be placed on base plate
The pipe of diameter, it is characterised in that：Positioner is provided with above the pipe, the positioner is a long location-plate, fixed
Position plate has location hole for different-diameter tube center position, and steel ball is put in pipe by location hole；The base plate
Surface is provided with one layer of non-sticking lining；Casing is provided with below the base plate, base plate is fixed on casing；The casing front is provided with
Window, stopwatch are fixed on the window.
Preferably, the location hole is arranged below stopper, is engaged between stopper and pipe, makes positioner be fixed on pipe
On son.
Preferably, the positioner is plastic, transparent material.
Preferably, the non-sticking lining is ceramic coating.
Preferably, the window is arranged on the upside of casing, is provided with drawer, drawer for shelf test tweezer on the downside of casing
The apparatus such as son, rag.
One layer of non-sticking lining is provided with the outside of the casing.
Further, the stopper is with diameter greater than steel ball size.
The beneficial effects of the utility model：This utility model simple structure, it is novel in design, steel ball is made by Design Orientation hole
Liquid center position can accurately be placed；By non-sticking lining being arranged in backplate surface, facilitate the cleaning of base plate greasy dirt；By setting
Casing is put, stopwatch is fixed on casing, is easy to the protection of stopwatch, while what is arranged on casing takes out storage of the note beneficial to article,
Will not be in disorder.
Description of the drawings
Fig. 1 is structural representation axonometric chart of the present utility model.
Fig. 2 is this utility model base arrangement schematic diagram.
Specific embodiment
With reference to the accompanying drawings and examples this utility model is further elaborated.
As shown in figure 1, a kind of tester for viscosity factor of the present utility model, including experiment steel ball, stopwatch 4, base plate 1, put
The pipe 2 and casing 3 of one group of different-diameter on the base plate.Wherein, base plate 1 is fixed on casing 3.It is provided with above pipe 2
Long location-plate 5, location-plate have location hole 6 for different-diameter tube center position, and location hole 6 is arranged below stopper 7,
It is engaged between stopper and pipe, long location-plate is fixed on pipe.Window is provided with the upside of 3 front of casing, stopwatch 4 is fixed on
On the window.Downside is provided with drawer 7, drawer for apparatus such as shelf test tweezers, rags.
As shown in Fig. 2 base plate 1 includes basal plate 1.1 and surface non-sticking lining 1.2；Non-sticking lining is ceramic coating.
Specifically used mode：
Long location-plate is fixed on pipe by stopper, steel ball has been pinched by location hole point with tweezers during student experimenting
It is not put in different pipes, while calculating time of the steel ball by AB on pipe by stopwatch on casing, each pipe has been tested
Cheng Hou, steel ball is tested for next pipe after wall sucking-off.After off-test, lower shoe is wiped with rag, while
The instruments such as tweezers, rag are put in casing drawer.
To sum up, this utility model reaches expected purpose.
