Description
Technical field
The utility model relates to a kind of Ubbelohde viscometer, particularly the full-automatic Ubbelohde viscometer of a kind of jacket type bottom sample introduction.
Background technology
Ubbelohde viscometer is mainly used in measuring the kinematic viscosity of liquid, it is a kind of capillary viscosimeter of gravity-type, be based on the principle design of relative measurement method, also namely measure the limiting viscosity of liquid according to the rate of outflow of liquid in kapillary, compare with other gravity-type viscosity meters, it belongs to suspension liquid column type viscosity meter.Existing Ubbelohde viscometer is comprised of dress liquid pipe, supervisor and arm, all from the top application of sample, the bottom discharge opeing, owing to being subjected to the impact of liquid level, having that poor accuracy, the sampling of measuring are inconvenient, a testing tube shortcoming such as easy cleaning not, and be the artificial visually examine when measuring, need to use the eye gaze scale mark, cooperate stopwatch to measure, introduce human factor, measuring result error is large; And what adopt when constant temperature is large-scale tank, not only wastes resource and the constant temperature effect is relatively poor.
The utility model content
Technical problem to be solved in the utility model is, provides a kind of jacket type bottom sample introduction full-automatic Ubbelohde viscometer.It is full automatic working, has advantages of to measure accurate, take a sample convenience, easy cleaning, good constant-temperature effect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: the full-automatic Ubbelohde viscometer of a kind of jacket type bottom sample introduction comprises chuck and is installed in chuck interior main test tube, liquid suction pipe and evacuated tube; Main test tube comprises and is positioned at top straight tube, impact bag, measurement ball, kapillary and the bottom application of sample pipe that same axis connects successively from top to bottom, and main test tube is communicated with liquid suction pipe and evacuated tube; Measure the ball top and be provided with and measure the position, the below of measuring ball is provided with lower measurements position, on chuck with measure the position and a lower measurement corresponding position is respectively equipped with the installation of sensors pipe.
The above-mentioned full-automatic Ubbelohde viscometer of jacket type bottom sample introduction, the upper end of described measurement ball is inserted in the impact bag, is provided with overflow vent on the top of measuring ball; Impact bag is communicated with waste liquid bottle by liquid suction pipe, at waste liquid bottle the vacuum drawing liquid pump is housed.
The full-automatic Ubbelohde viscometer of aforesaid jacket type bottom sample introduction, described overflow vent is tilt port.
The full-automatic Ubbelohde viscometer of aforesaid jacket type bottom sample introduction, described chuck is glass material, chuck and the complete sealed attachment of main test tube, liquid suction pipe and evacuated tube.
The full-automatic Ubbelohde viscometer of aforesaid jacket type bottom sample introduction is provided with inlet in the bottom of described chuck, and the top is provided with liquid outlet, and inlet is connected thermostat with liquid outlet.
The full-automatic Ubbelohde viscometer of aforesaid jacket type bottom sample introduction, solenoid valve is equipped with on the top of described top straight tube and evacuated tube.
Compared with prior art, the utlity model has following advantage:
1, can realize all automatic measurement analysis, increase substantially the accuracy of measurement, avoid estimating the personal error of generation.Prior art is the artificial visually examine when measuring, and needs to use the eye gaze scale mark, cooperates stopwatch to measure, and introduces human factor, and measuring result error is large.Chuck of the present invention and measuring position are provided with corresponding installation of sensors pipe, can by accurately monitor liquid level through situation such as auxiliary group of equipment such as infrared rays, accurately obtain liquid and flow through the upper and lower time of measuring the position; The installation of sensors pipe does not contact with liquid in the chuck, avoids the liquid disturbed test, can select flexibly various liquid level sensors again, has formulated preferred plan for realizing automatically measuring.
2, constant temperature measurement for the measurement of viscosity provides a stable temperature, has improved the accuracy of measuring, and energy-conservation, economical.A temperature flowability to the viscosity sample has a great impact, and also is one of key factor that affects viscosity measurement; Because the relation of viscosity and temperature is very close, viscosity measurement all need to be carried out under constant temperature; The calibration cell that is used for Ubbelohde viscometer must possess following condition: (1) sufficiently high temperature-controlled precision and warm homogeneity; (2) cell wall is transparent, has view window at least, so that the plumbness of temperature and inspection viscosity meter etc. is observed, read in timing; (3) cell body should be enough dark, makes the viscosity meter that is placed in one that the above surplus of about 2cm be arranged up and down; What prior art adopted is that large-scale tank carries out constant temperature, not only waste resource, and the constant temperature effect is also relatively poor.Chuck of the present invention is provided with upper and lower liquid in-out mouth and is communicated with thermostat, and isothermal liquid guarantees the flowability that sample is good by circulating the stable temperature field of manufacturing, thereby improves the degree of accuracy of measuring.
Add sample thief when 3, measuring and suck from main test tube bottom, not only inhale sample prescription just, can avoid the top application of sample to produce air bubble, and easy to clean, drying effect are good, continuous coverage is convenient and swift.The kapillary of Ubbelohde viscometer must and wash with the cleaning solution immersion, can use after 105 ℃ of oven dry; Must vertically be fixed in the water bath with thermostatic control, otherwise affect flow velocity, cause the error of measurement result.The Ubbelohde viscometer of prior art need to add a large amount of samples and repeatedly washes by measuring tube after a upper sample test is complete, from the bottom waste liquid is got rid of, and routinely experiment need be carried out 3 such operations and just calculate displacement and finish; And clean the method for soaking that can adopt, filling whole viscosity tube needs a lot of reagent.And the present invention adopts the mode of displacement, similar new sample is directly sucked displacement get final product; In like manner, can replace sample to finish with solvent during cleaning, only need to clean a pipe, reduce reagent consumption.
4, measuring repeatability is good.Before measuring, the Ubbelohde viscometer of prior art needs sample to be inhaled or be pressed onto the upper only about half of position of bead of supervisor, but at every turn all can be different, can not avoid the mushing error of bringing to measurement because of the height of liquid level difference; And overflow vent of the present invention is tilt port, affected by liquid level little, and each liquid level that promotes is constant, can reduce error during duplicate measurements.
