Abstract
The utility model relates to a closed constant temperature viscometer which comprises a test tube, a tester, a test ball, an infrared induction device, an insulating cover and an upper cover provided with a ball falling hole, wherein the insulating cover is sleeved on the test tube, the upper cover is arranged above the insulating cover, the test tube is arranged in a space formed by the insulating cover and the upper cover, and the infrared induction device is arranged outside the test tube and is connected with the tester. The closed constant temperature viscometer disclosed by the utility model is good in insulating effect, stable in test environment, convenient to use and more precise in measurement precision, and the difficulty on viscosity experiment of the measured fluid is reduced, and the experimental efficiency is improved.
Description
Technical field
The utility model relates to a kind of detecting instrument, and definite says, is a kind of closed constant temperature viscosity apparatus.
Background technology
At present, in the method for measuring liquid viscosity, use the most general falling ball method that is, namely in a vertical glass infuser of placing, fill with the liquid that wish is measured, on glass infuser, doing two marks on glass infuser, to delimit a segment distance, when bead, when falling to the first mark liquid, the top of glass infuser starts timing, during to the second mark, stop timing, by the distance between the time interval and mark, determine the movement velocity of bead, again according to the diameter of bead and glass infuser, the viscosity of the calculation of parameter liquid such as bead and fluid density.Most critical is how to measure accurately the time interval of bead through the twice mark 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 by stopwatch, carrying out meter, this method is owing to by eye-observation and armrest, operating, so error is larger; Although adopt the laser optical method precision very high, laser beam is thinner, bead is difficult to guarantee laser beam is covered when falling, therefore exist and measure failed possibility, 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 determinator of brand new to solve the problems referred to above.
The utility model adopts following technical scheme to be realized:
The disclosed closed constant temperature viscosity apparatus of the utility model, comprise testing tube, tester, test ball, infrared induction device, muff and be provided with the upper cover of ball-dropping hole, described muff is set on testing tube, described upper cover is arranged on the muff top and testing tube is arranged in the space of muff and upper cover formation, described infrared induction device is arranged on the testing tube outside, and described infrared induction device is connected with tester.
A kind of improvement of the disclosed closed constant temperature viscosity apparatus of the utility model, described infrared induction device arranges two groups, is separately positioned on the top and bottom of testing tube.
The utility model adopts infrared ray as falling sphere speed and time measurement means, adopt simultaneously muff that the thermal environment of temperature constant is provided for viscosity apparatus, can guarantee consistance and the stability of measures ambient temperature, make the precision of measuring more accurate, reduced the difficulty of measuring viscosity of liquid, improve the efficiency of experiment, also had advantages of simultaneously the cheap and equipment simple and stable of use cost.
The accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Wherein: 1, testing tube; 2, tester; 3, test ball; 4, infrared induction device;
5, muff.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail:
The disclosed closed constant temperature viscosity apparatus of the utility model, comprise testing tube 1, tester 2, test ball 3, infrared induction device 4, muff 5 and be provided with the upper cover of ball-dropping hole, described muff 5 is set on testing tube 1, described upper cover is arranged on muff 5 tops and testing tube 1 is arranged in the space of muff 5 and upper cover formation, described infrared induction device 4 is arranged on testing tube 1 outside, and described infrared induction device 4 is connected with tester 2.
As a kind of preferred, described infrared induction device 4 arranges two groups, is separately positioned on the top and bottom of testing tube 1.
The utility model adopts infrared ray as falling sphere speed and time measurement means, adopt simultaneously muff that the thermal environment of temperature constant is provided for viscosity apparatus, can guarantee consistance and the stability of measures ambient temperature, make the precision of measuring more accurate, reduced the difficulty of measuring viscosity of liquid, improve the efficiency of experiment, also had advantages of simultaneously the cheap and equipment simple and stable of use cost.
