When reaching the first electromagnetic cut-off valve 131, each valve is in the state at the beginning of the test, and an oil mixing cycle is completed.

During the counterclockwise rotation of the first oil-mixing interface, due to the further mixing of the first oil product and the second oil product during the rotation process, the chromaticity at the first oil-mixing interface changes, and the experimenter can see through the transparent arc tube at any time To observe, the flowmeter 121, chromaticity tester 122 and temperature sensor 123 of the two groups of mixed oil parameter measuring devices 12 measure the flow rate, chromaticity and temperature of the test oil flowing through the interior in real time online, and transmit each parameter to the Data acquisition and control module.

According to the test requirements, the aforementioned operations can be repeated in turn, and the length of the oil-contaminated section over time can be obtained through the detection of the color and density of the oil-contaminated section.

From the above, the device for testing the development law of oil-mixed interface in the sequential delivery of refined oil of the present invention has the following beneficial effects:

(2) In the test device for the development law of the mixed oil interface in the sequential delivery of finished oil of the present invention, the oil product is mixed in the mode of the test loop, which can meet the requirements of the long-distance delivery test measurement, and the bending radius of the test loop is relatively large. Neutralize the influence of centrifugal force and centripetal force on the oil mixing parameters during the test oil flow process, and further improve the test accuracy;

(3) In the test device for the development law of the mixed oil interface in the sequential delivery of refined oil of the present invention, the test loop is formed by connecting transparent circular arc tubes with smooth inner walls in multiple sections, and each transparent circular arc tube is made of transparent tempered glass tubes, which can be observed intuitively The flow conditions and color changes of the test oil products in the test loop realize the research and determination of the mixed oil length in the process of sequentially conveying refined oil from the perspective of chromaticity, and the change of chromaticity is more sensitive, making the sequential conveying of refined oil mixed in the present invention The test accuracy of the oil interface development rule test device is further improved; the inner wall of the transparent circular arc tube is smooth, which avoids the disturbance of the tube wall to the mixed oil, so that the experimental accuracy of the mixed oil parameters measured by the device test is further improved;

(4) The test device for the sequential delivery of oil-mixed oil interface development law of the present invention is simple in structure, easy to operate, and beneficial to popularization and application.

The above descriptions are only illustrative specific implementations of the present invention, and are not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principle of the present invention shall fall within the protection scope of the present invention.
