[0002] Demulsification is an important indicator to measure the ability of turbine oil to separate from water. When the oil has strong demulsification performance, the oil-water emulsion can be quickly separated in the oil tank, thereby effectively reducing the damage of the oil film, preventing the corrosion of metal parts and delaying the aging of the oil, ensuring the normal operation of the equipment. However, if the demulsification performance is weak, the oil-water emulsion is separated slowly, which will lead to the rupture of the oil film, the corrosion of metal parts, and the acceleration of oil aging. These will increase the friction between parts and may cause equipment overheating or even damage.

[0055] Operation process: When the test tube 103e is moved into the storage tube, the movable arc block 201c is pushed to move in the displacement groove 201b. At this time, the embedded block 201g in the test tube 103e moves out of the compression groove 201e due to the action of the first spring 201f and touches the displacement groove 201b to make a sound. At this time, the movable arc block 201c and the embedded block 201g occupy the entire displacement groove 201b so that the test tube 103e will not fall off, and the servo motor 102a can be driven to drive the first threaded rod 102b and the first threaded rod 102b connected to the test tube 103e. The lifting seat 102f and the storage shell 103d are deflected 90 degrees and moved downward, so that the test tube 103e can enter the placement shell 101c, and the test tube 103e is heated by the heating seat 101b to improve the test efficiency. During the installation of the test tube 103e, the lifting block 201d on the moving arc block 201c pushes the passive block 203c to move the falling block 203b and the moving block 102c, and the embedded block 201g on the moving block 102c moves into the follower ring 203e corresponding to the falling groove 202c;
[0056] When the motor on the second energy storage block 203h is started, the moving block 102c and the first energy storage block 202e on the moving block 102c can also move accordingly, so that the rotating shaft 202f and the stirring rod 202g on the first energy storage block 202e can move synchronously, and only the part where the test tube 103e is installed will move accordingly. When the rotating shaft 202f and the stirring rod 202g enter the test tube 103e, the motor on the first energy storage block 202e can be controlled to start so that the rotating shaft 202f rotates and the stirring rod 202g rotates synchronously, so that the reagent in the test tube 103e is stirred, which is convenient for subsequent further detection and observation of the demulsification degree.
[0057] Example 3
[0058] Reference Fig.11 - Fig.12 , as a third embodiment of the present invention, provides a method for determining demulsification degree, comprising the following steps:
[0059] S1, through preparation and initial setup and water bath heating;
[0060] S2, then automatically measure and record and output the results;
[0061] S3. Finally, automatic cleaning and drying are performed to complete the whole process of demulsification degree detection.
[0062] Among them, water bath heating and constant temperature control are composed of temperature sensors, including thermostats, over-temperature protection switches, etc.
[0063] Among them: the temperature sensor adopts 4-wire PT100 to ensure accuracy; the over-temperature protection switch adopts 85℃ temperature protection switch; the thermostat adopts intelligent thermostat. The main parameters are shown in Table 1 below:
[0064] Table 1 Main parameters of intelligent thermostat
[0065]
[0066]
[0067] The water bath thermostatic automatic temperature control module has the functions of water bath temperature control, water temperature value setting, automatic water circulation, real-time temperature display, etc. It adopts PID control technology, and improves the analog-to-digital conversion (A / D) accuracy of the PID circuit to 24 bits, the digital-to-analog conversion (D / A) accuracy to 16 bits, increases the number of floating-point arithmetic bits and increases the minimum control output percentage (OP) to 0.01%, and controls the accuracy of constant temperature control within 0.1%.
[0068] Among them, multiple channels can selectively lift and stir automatically;
[0069] The device is designed to realize functions such as automatic lifting and automatic constant speed stirring after the test tube 103e is installed with selectable channels. Before the test begins, 1-4 test tubes 103e with samples are placed in the test tube 103e installation position. After the test is started, the installed test tube 103e will be moved to the corresponding position first. After the water bath constant temperature time of the sample to be tested reaches 20 minutes, the stirring blade at the corresponding test tube 103e position is controlled to extend into the test tube 103e, and the stirring is started and continued for 5 minutes. After the stirring is completed, the stirring rod 202g is controlled to rise again. Due to the structure of the stirring rod 202g, it is convenient for the emulsion on it to flow back into the test tube 103e.
[0070] Among them, machine vision automatic detection;
[0071] The machine vision automatic detection module adopts the method of industrial camera + visual detection, which is composed of PC host computer, machine vision software, single chip control unit, high-definition camera, etc. It has the functions of automatically judging the end point of oil sample demulsification degree determination and automatically detecting the height of emulsion layer, such as Fig.11 As shown;
[0072] The machine vision detection module consists of a high-definition camera and a host computer equipped with machine vision algorithm software. When the oil sample is stirred, the stirring rod is raised, and the timing starts at the same time. The machine vision detection system also starts to intervene. The camera takes pictures of the real-time status of 1-4 oil samples to be tested at a speed of dozens of frames per second. The pictures are transmitted to the host computer. The host computer software determines the upper and lower positions of the emulsified part through digital detection and boundary detection, and determines the width of the emulsified layer and the position of the lower liquid level of the oil through the distance measurement algorithm. When the width of the emulsified layer is less than or equal to 3mL, the measurement ends, the timing result is obtained, and the pictures taken are stored in the host computer for inspection. The machine vision detection method is used to do these jobs that previously required manual work, completely liberating manpower, thereby realizing truly fully automatic detection.
[0073] Among them, automatic cleaning and drying, such as Fig.12 As shown;
[0074] The automatic cleaning and drying module of the test tube 103e is composed of a cleaning paddle assembly, a switching valve assembly, a pipeline assembly, a dry air generating assembly, a control unit, etc., and has the functions of automatically dropping the cleaning paddle, automatically discharging waste oil / waste cleaning liquid / waste distilled water / waste petroleum ether, automatically adding cleaning liquid / distilled water / petroleum ether, automatically washing the test tube 103e, automatically drying the test tube 103e, and automatically retracting the cleaning paddle;
[0075] After the determination is completed, the equipment automatically drops the cleaning paddle, and the switching valve switches to the waste liquid discharge pipeline to discharge the residual waste oil in the test tube 103e; then, the switching valve switches to the cleaning liquid addition pipeline and introduces 80mL of cleaning liquid, and then starts the cleaning paddle to stir and clean the test tube 103e. After the cleaning is completed, the switching valve switches to the waste liquid discharge pipeline to discharge the waste cleaning liquid; the switching valve switches to the distilled water addition pipeline and introduces 80mL of distilled water, and then starts the cleaning paddle to stir and clean the test tube 103e. After the cleaning is completed, the switching valve switches to the waste liquid discharge pipeline to discharge the waste distilled water; the switching valve switches to the petroleum ether addition pipeline and introduces 80mL of petroleum ether, and then starts the cleaning paddle to stir and clean the test tube 103e. After the cleaning is completed, the switching valve switches to the waste liquid discharge pipeline to discharge the waste petroleum ether; the switching valve switches to the distilled water addition pipeline and adds 80mL of distilled water, and then starts the cleaning paddle to stir and clean the test tube 103e. After the cleaning is completed, the switching valve switches to the waste liquid discharge pipeline to discharge the waste distilled water; repeat this operation to ensure that the oil sample is thoroughly cleaned.
[0076] After the cleaning is completed, the switching valve is switched to the dry air channel, and the dry air generating component is started to blow out 54°C hot air to dry the test tube 103e. After the drying is completed, the cleaning paddle is put away, and the entire detection process of the equipment is completed.
[0077] Among them, automatic timing and printing;
[0078] The automatic timing and printing module consists of a PC host computer, a single-chip control unit, a printer, etc. The timing starts from the injection of 40mL of oil sample and 40mL of distilled water, the constant temperature water bath is set for 20 minutes, and the sample to be tested is stirred for 5 minutes. After stirring, the emulsion separation time is measured until the emulsion layer is less than or equal to 3mL to obtain the demulsification time, and the test results are automatically printed through the printer;
[0079] The demulsification degree of turbine oil is automatically tested by means of a demulsification degree tester, and the entire testing process is automatically controlled and tested, so as to greatly shorten the time for sample testing. At the same time, the influence of manual judgment and manual timing on the test results is eliminated, making the test data more stable and accurate. The test process is made more automatic and intelligent, reducing manpower, lowering human resource requirements, liberating labor, and improving the stability, accuracy and work efficiency of test results.
