Abstract
The utility model relates to an inductive ball falling method liquid viscosity measuring instrument, which comprises a glass test pipe, a test instrument, a test ball and infrared ray sensors, wherein the infrared ray sensors are arranged at the outer side of the test pipe, and the two groups of infrared ray sensors are arranged and are respectively arranged at the upper end and the lower end of the test pipe. The inductive ball falling method liquid viscosity measuring instrument adopts the infrared ray for replacing the existing visual measurement or laser measurement to be used as a measuring measure, so that the measurement precision is high, the difficulty of experiments for measuring the liquid viscosity is reduced, and the experiment efficiency is improved.
Description
Technical field
The utility model relates to a kind of detecting instrument, and definite says, is a kind of falling ball method liquid viscosity analyzer.
Background technology
At present, in the method for measuring liquid viscosity, use the most general falling ball method that is, promptly in a vertical glass infuser of placing, fill with the liquid that desire is measured, doing two marks on the glass infuser on glass infuser, to delimit a segment distance, when falling to the first road mark liquid from the top of glass infuser, bead picks up counting, stop timing during to the second road mark, determine the movement velocity of bead by the distance between the time interval and the mark, again according to the diameter of bead and glass infuser, the viscosity of calculation of parameter liquid such as bead and fluid density.Most critical is how to measure the time interval of bead through the twice mark accurately in this process, general measuring method is ocular estimate and laser optical method at present, even ocular estimate detects by an unaided eye, then when coming meter by stopwatch, this method is because by the operation of eye-observation and armrest, so error is bigger; Though adopt the laser optical method precision very high, laser beam is thinner, bead is difficult to guarantee laser beam is covered when falling, and therefore has the possibility of measuring failure, makes troubles to surveying work.
Summary of the invention
The purpose of this utility model is to provide a kind of falling ball method liquid viscosity analyzer of brand new to solve the problems referred to above.
The utility model adopts following technical scheme to be realized:
A kind of induction type falling ball method liquid viscosity analyzer, comprise glass testing tube, tester, test ball, described analyzer also comprises the infrared induction device, described infrared induction device is arranged on the testing tube outside, described infrared induction device is connected with tester, and described infrared induction device is provided with two groups, is separately positioned on the top and bottom of testing tube.
The utility model adopts infrared ray as measurement means, makes the precision of measurement more accurate, has reduced the difficulty of measuring viscosity of liquid, has improved the efficient of experiment.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein: 1-testing tube, 2-tester, 3-test ball, 4-infrared induction device.
Embodiment
Below in conjunction with Figure of description the utility model is described in further detail:
The utility model relates to a kind of induction type falling ball method liquid viscosity analyzer, comprise the testing tube 1 that a glass is made, upper end and lower end at testing tube respectively are provided with one group of infrared induction device 4, described infrared induction device 4 connects tester 2, described infrared induction device 4 is divided into infrared end and infrared ray receiving end, both are oppositely arranged, and the infrared signal that its result who reaches sends for the infrared end passes testing tube 1, is then received by the infrared ray receiving end.
Below by an object lesson the utility model is described:
At first, will fill testing liquid in the testing tube, make bead fall into liquid from the testing tube top, when first infrared induction device of bead process, the infrared signal that first infrared induction device sends is cut off by bead, and it gives tester a commencing signal, and tester picks up counting; When bead during through second infrared induction device, the infrared signal that second infrared induction device sends is cut off by bead, and it has given the tester stop signal, then just can draw the viscosity of testing liquid according to the data that detect.
