The utility model is composed of an instrument bracket which is provided with a slid slot and a ruler, a four-core socket, a transparent container with one closed end, an instrument base (which is provided with a balance level, and regulating screws are arranged below the base), a positioning cover, a U-T switching device which is composed of four photoelectric doors, etc. The utility model adopts light balls and utilizes multiple photoelectric doors which are connected with a computer millisecond meter to test the liquid viscosity coefficient. The utility model has the advantages of simple structure, convenient operation, strong reliability and high measuring precision.
Description
The utility model relates to the coefficient of viscosity technical field of measurement and test, especially in Application in Teaching.
At present domestic each colleges and universities almost all adopt manual time-keeping when adopting falling ball method to measure coefficient of viscosity.Adopt the method timing, the action of people during by stopwatch and falling sphere be initial to fall and the moment of the end of falling is difficult to cause personal error often synchronously.And it is measure number of times, even more usually at 6-10 time.For above-mentioned reasons, the method ubiquity that extensively adopts at present two problems: the accuracy of timekeeping of (1) manual time-keeping is not accurate enough.(2) because most liquid (as glycerine etc.) is after temperature changes, very big to the influence of coefficient of viscosity.When fluid temperature once changed, the rate of change of coefficient of viscosity was sometimes up to more than 10%.Because the number of times of measuring is more, from beginning to measure to generally need finishing tens of minutes to the percentage clock.Because many students enter all multifactor influences such as laboratory, can make in the laboratory and the fluid temperature rising in the meantime, general temperature lift-off value can reach 1-2 ℃, thereby causes that each time measured value deviation is excessive.Like this, when we survey data substitution Error Calculation formula with institute, will inevitably cause than mistake.
The purpose of this utility model is to obtain one group of high-precision time difference data by a falling sphere test, thereby calculates coefficient of viscosity.
The utility model is realized by following scheme.The transparent cylindrical container that materials such as glass or organic glass are manufactured is vertically mounted on the horizontal base.At a side mounting and fixing bracket of container, a plurality of photogate are installed on the fixed support.Photogate equidistantly distributes vertically in the side of cylindrical container, and per from top to bottom two photogate can be connected into one group mutually, and is connected to form the U-T transformational structure with a four-core socket.When measuring coefficient of viscosity, a density is put into liquid less than 6 gram/cubic centimetres and greater than the bead of survey fluid density by the top center of container.Each group photogate is linked to each other with computermatic digital millisecond counter by the four-core socket.When bead falls by liquid in container,, show by digital millisecond counter to obtain a plurality of time time difference value, just can adopt the coefficient of viscosity that calculates the transparency liquid under the transient temperature by the method for difference then through each photogate.
Fig. 1 is many photogate coefficient of viscosity tester.
Wherein: the 1-8 photogate; 9 spirit-leveling instruments; 10 adjusting screw; 11 bases; 12 four-core sockets; 13 tighten up screw; 14 fixed supports; 15 glass infusers; 16 transparency liquids; 17 location lids; 18 beads.
Below in conjunction with description of drawings embodiment.
Embodiment 1: the employing glass infuser is a liquid container.Fixed support 14 and glass infuser 15 are vertically mounted on the base 11.Photogate 1 and 2 is in series among eight photogate 1-8, and 3 and 4 are in series, and 5 and 6 are in series, and 7 and 8 are in series, and constitutes the U-T transformational structure.Four four-core sockets 12 are installed on the fixed support.Be painted with meter ruler on the fixed support, and have chute.Photogate is fixed on the support bracket fastened chute by tightening up screw 13.The effect of chute is to make photogate can move and adjust distance each other, and spirit-leveling instrument 9 is housed above the base 11, and three adjusting screw 10 are arranged below, can be with base furnishing horizontality.The location lid 17 that center drilling is arranged at the top of glass infuser 15.Adopt aluminium matter bead.
When the test liquid coefficient of viscosity, measure △ t12 by digital millisecond counter, △ t34, △ t56, △ t78, △ t13, △ t35, △ t57 waits seven time difference datas, adopts then by the difference method and handles experimental data.
Embodiment 2: adopt eight expanding units, can lay 16 photogate simultaneously, one-shot measurement obtains 15 groups of data.
Many photogate coefficient of viscosity tester adopts photogate to link to each other with computermatic digital millisecond counter, shows falling sphere time time difference value, measuring accuracy height by digital millisecond counter.This testing tool is simple in structure, easy to operate, good reliability, be easy to promote.
