Abstract
The utility model relates to an induction-type ball-falling method liquid viscosity determinator which is characterized in that the outside of the glass measuring cylinder full of the liquid to be tested is horizontally sheathed with two induction coils, making the falling metal balls in the liquid of the measuring cylinder drill through the two induction coils in sequence. The perforation of the metal balls can cause the changes of induction coil electricity parameters. The lead wires of the two induction coils are connected with the determinator main set which can work out with accuracy testing of ball falling speed and the viscosity of liquid through processing the signals about the changes of electricity parameters and the application of other parameters like the distance between coils, the diameters of balls and measuring cylinder, and the density of balls and liquid. The utility model reduces the difficulty of the liquid viscosity testing experiment, improves the efficiency of the experiment, and gets no influence from light transmittance of liquid.
Description
Affiliated technical field
The utility model relates to a kind of teaching and experiment equipment, especially induction type falling ball method liquid viscosity analyzer that carries out falling ball method liquid viscosity mensuration with induction mode.
Background technology
In the instrument of measuring liquid viscosity, the most general at present with the method for measuring liquid viscosity with falling ball method.This method normally fills with testing liquid in a vertical glass cylinder of placing, when a prill falls liquid from the top of graduated cylinder and during successively through certain two specific scale mark position, according to bead the time interval when these two specific scale mark positions and the distance between two scale marks just can be regarded as the speed that falls of bead, according to the bead that records and the parameters such as diameter, bead and density of liquid of graduated cylinder, the viscosity of using corresponding physical computing formula just can calculate liquid is come again.And measure time interval when can whether crucial accurately liquid viscosity one of measure bead exactly exactly through two specific scale mark positions in this way, and further calculate the speed that bead falls according to the distance between two scale marks.Measure this time interval, the method for taking at present has two kinds: the first is directly come timing with range estimation with by the method for stopwatch, and this method is owing to being to operate by eye-observation with hand, so the error ratio of operational measure is bigger; It two is to use the method for laser beam secondary shading timing is measured, though the precision of measuring is higher, because the light beam of laser is thinner, bead is difficult to guarantee secondary shading exactly in dropping process.In addition, above-mentioned two kinds of methods all can't be measured being difficult for the liquid of printing opacity.
Summary of the invention
The utility model has designed a kind of falling ball method liquid viscosity analyzer of induction type at above-mentioned existing problems.This instrument adopts the method for induction to survey when falling through certain two ad-hoc location to bead, and measures the time interval of bead through these two ad-hoc locations with the method for electric time-keeping, thereby calculates the speed that bead falls.So both guarantee the accuracy that the time interval and falling speed are measured, and avoided again when requiring bead to fall and strictness to have aimed at the problem of laser beam, thereby reduced the difficulty of experiment, improved the efficient of experiment.Even for lighttight liquid, still can normally carry out viscosity measurement.
The technical scheme that its technical matters that solves the utility model adopts is: the diverse location up and down outside the glass cylinder of contain fluid overlaps two inductive coils respectively, when the prill that falls in the liquid at graduated cylinder passes these two inductive coils successively, can cause the variation of inductive coil electrical quantity, the extension line of this inductive coil is linked to each other with instrument host.Instrument host is handled by the signal that this electrical quantity is changed, and the parameters such as diameter, bead and density of liquid of distance, bead and graduated cylinder between the substitution respective coil, can accurately realize the measurement of bead falling speed and the calculating of liquid viscosity.
The beneficial effects of the utility model are: reduce the difficulty of measuring viscosity of liquid, improved the efficient of experiment, and the not influence of liquid body printing opacity degree.
Description of drawings
Accompanying drawing is each critical piece structural representation of the present invention.
In the accompanying drawings: 1. two inductive coils that are enclosed within graduated cylinder outside; 2. glass cylinder; 3. the testing liquid in the glass cylinder; 4. instrument host.
Embodiment
In the accompanying drawings, the outside of filling with the glass cylinder (2) of testing liquid (3) is being overlapped two inductive coils (1) abreast, the extension line of these two inductive coils is linked to each other with instrument host (4), so that the signal that electrical quantity changes when allowing instrument host that these two inductive coils (1) are detected prill and pass is done further to analyze, just can calculate the viscosity of the testing liquid (3) in the glass cylinder (2).
Claims (1)
1. induction type falling ball method liquid viscosity analyzer, it is characterized in that: put two inductive coils abreast in the outside of the glass cylinder that fills with testing liquid, make the prill that falls in the liquid of graduated cylinder can pass this two inductive coils successively, the extension line with these two inductive coils links to each other with instrument host respectively again.
