Method measures its dynamic viscosity.The disadvantage is that constituting complicated, it is difficult to clean, sample consumption is big (about 20ml), and minute is long (about
30min), it is very difficult to its viscosity of quick precise measurement.Currently, there are the shortcomings of three aspects for conventional use of viscosity instrument: sample
And cleaning agent dosage is big；It is thorough to be difficult cleaning since its volume is larger；It measures too long with heating time.
Summary of the invention
The utility model provides a kind of oil product viscosity milligram ammonia measurement device, to solve to produce currently used for measurement petroleum
The problem that structure is complicated for product viscosity device, cleaning is difficult, sample consumption is big and minute is long.

Further, constant temperature bath temperature sensor is equipped in constant temperature bath.
The utility model detects laser displacement sensor applied to viscosmeter, accurate time control (0.0025
Second, precision are as follows: 25/,100 ten thousand), ensure that total measurement accuracy and repeatability, overcome conventional viscosity measurement instrument using red
The not high defect of measurement accuracy caused by external square type detection.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of oil product viscosity milligram ammonia measurement device.
Fig. 2 is a kind of oil product viscosity milligram ammonia measurement device detection schematic diagram.
Wherein: 1, constant temperature bath, 2, viscosmeter pipe, 3, capillary, 4, viscosity detection cell, 5, laser displacement sensor, 6, light
Galvanic reflex plate, 7, constant temperature bath temperature sensor.
Specific embodiment
Below in conjunction with attached drawing and specific embodiment, the present invention is further illustrated.
As shown in Figure 1, a kind of oil product viscosity milligram ammonia measurement device, which includes a constant temperature bath 1, the constant temperature
The volume of bath is 7.5L；Constant temperature bath temperature sensor 7 is equipped in constant temperature bath, temperature range is 20-120 DEG C.For measuring stone
The viscosmeter pipe 2 of oil product viscosity is inserted into constant temperature bath 1, capillary 3 is equipped in viscosmeter pipe 2, in viscosmeter pipe 2
Lower part is equipped with viscosity detection cell 4, it is preferred that two viscosity detection cells 4 are arranged, pass through capillary 3 between two viscosity detection cells 4
Connection.It is equipped with laser displacement sensor 5 in the side of viscosity detection cell 4, due to being preferably provided with two 4 (volumes of viscosity detection cell
May be the same or different), it is therefore desirable to it is equipped with the test point of three laser displacement sensors, from top to bottom, three accordingly
A test point is that position is successively set at the sample inlet of viscosity detection cell 1, is at the sample export of viscosity detection cell 1 and glutinous
It spends at the sample export of detection cell 2.Photoelectric reflection plate 6 is equipped in the other side of viscosity detection cell 4.
As shown in Fig. 2, a kind of oil product viscosity milligram ammonia measurement device detection schematic diagram.The inspection of viscosmeter sample liquid level
Survey is one of key point of the utility model, i.e. the meniscus detection of sample, and laser displacement sensor is examined applied to viscosmeter
It surveys.When the meniscus of sample passes through the 1st test point, laser displacement sensor 5 obtains inductive signal, when the meniscus of sample
When by the 2nd test point, laser displacement sensor 5 obtains inductive signal again, according to the calculation formula of liquid motion viscosity
(ν=C τ, wherein C be capillary constant, the capillary constant of the viscosmeter of different size be it is determining, τ be sample outflow inspection
Time needed for surveying pond body product V；If temperature is t DEG C, liquid motion viscosity when measuring temperature is t DEG C is expressed as: ν t=C
τ t), the viscosity of you can get it sample, similarly, sample meniscus can be counted again by the 2nd test point and the 3rd test point
Sample viscosity is calculated, as comparing.
Since laser action can be unable to get reflection letter directly through directive unlimited distance when the pipeline of glassware
Number, it is therefore desirable to photoelectric reflection plate 6 is set in the other side of tube wall, so that auxiliary laser displacement sensor 5 judges whether there is sample
Product liquid flows through viscosity detection cell 4.
The relevant detection device of the utility model, such as constant temperature bath temperature sensor 7 and laser displacement sensor 5, Yi Jiqing
It washes equipment, gas source and ancillary equipment and is respectively connected with computer control system, so as to be accurately controlled temperature, reach ± 0.01
℃.Entire measurement links are automatically performed by instrument completely, and every step has clearly that information is shown, are convenient for changing viscosmeter pipe, with
Adapt to the sample of different coefficient of viscosities；It is set as a kind of micromation, high-precision automatic integrated makeup, the utility model is not only full
The multi-field rigors of foot, have efficient sample feeding, excellent repeatability, man machine operation interface, when having saved
Between and consumptive material, while improve viscosity analysis accuracy, improve working efficiency, mitigate analysis personnel labor intensity.
Due to the miniaturization feature of the utility model, each sample only needs 0.3~0.5ml, is conventional viscosity analysis sample
The consumption of the 1/20 of dosage, same cleaning agent is extremely low, and only conventional 10%.The measurement of sample can be increased simultaneously without increasing
Add the volume of constant temperature bath 1.
