Description

Technical Field

[0001] The utility model belongs to the technical field of demulsification degree detection, and particularly relates to a device for detecting the demulsification degree of turbine oil. Background Art

[0002] The demulsification degree refers to the time for water-oil separation measured under specified experimental conditions when an emulsion is formed by mixing oil and water, which is one of the main indicators for measuring the water-oil separation performance of oil products. During the operation of a turbine, if the water content in its lubricating oil system exceeds the standard, emulsification will occur under the action of surfactants and agitation, thus destroying the oil film on the metal surface. In addition, it is also prone to cause corrosion of metal components, accelerate the aging of oil products, and generate oil sludge. As an important indicator of turbine oil, the rapid and accurate detection of the demulsification degree is of great significance for ensuring the quality of oil products and improving production efficiency. At present, the detection of the demulsification degree of turbine oil is usually carried out by manual sampling, and the time is recorded after visually judging the water-oil separation. This measurement method has certain limitations and the results are not accurate. Content of the Utility Model

[0016] Refer to Figure 1 , according to the embodiment of the present invention Figure 1 A turbine oil demulsification degree detection device according to an embodiment of the present invention includes: a main control module 1, a reaction module 2, a constant temperature device 3, and a measurement module 4. The main control module 1 is electrically connected to the constant temperature device 3 and the measurement module 4 respectively. The main control module 1 is used to drive the measurement module 4 and the constant temperature device 3 to operate, and record the time when the measurement module 4 sends a test signal. The reaction module 2 is used to prepare an emulsion. The constant temperature device 3 is used to provide a constant temperature environment for the reaction module 2. The measurement module 4 is arranged in the constant temperature device 3 to monitor the state of the emulsion in the constant temperature device 3 and feedback a test signal to the main control module 1.

[0017] Specifically, the reaction module 2 includes: a first solution storage bottle 21, a second solution storage bottle 22, a third solution storage bottle 23, a pipette pump 24, and a reactor 25. Among them, one end of the pipette pump 24 is respectively connected to the first solution storage bottle 22, the second solution storage bottle 23, and the third solution storage bottle 24 through a solenoid valve 26, and the other end of the pipette pump 24 is connected to the reactor 27. The reactor 27 is arranged in the constant temperature device 3, and the height of the reactor is greater than the liquid level height of the solution in the constant temperature device.

[0018] Under the quantitative control of the solenoid valve, the pipette pump 24 can extract a quantitative solution from the first solution storage bottle 21 and the second solution storage bottle 22 respectively, so as to form an emulsion in the reactor 27. Among them, the first solution storage bottle 21, the second solution storage bottle 22, and the third solution storage bottle 23 store oil samples, water, and cleaning agents respectively. Preferably, in other embodiments, corresponding telescopic rods and stirrers 6 and other devices can also be arranged in the reactor 25 to accelerate the formation speed of the emulsion in the reactor.

[0019] Specifically, the measurement module 4 includes: a monochromatic light generator 41, a laser generator 42, a refractometer 43, and a photometer 44. The monochromatic light generator 41 and the laser generator 42 are respectively fixed on the inner peripheral wall of the water bath 31, and the refractometer and the photometer are respectively fixed on the outer peripheral wall of the water bath 31. Among them, the monochromatic light generator 41 is located below the laser generator 42. The emission signal of the monochromatic light generator 41 is received by the photometer 43, and the emission signal of the laser generator 42 is received by the refractometer 44. The connection line between the emission point of the monochromatic light generator 41 and the photometer 44 is perpendicular to the central axis of the reactor 25. The connection line between the emission point of the monochromatic light generator 41 and the photometer 44 is located below the liquid level in the reactor 25, and the connection line between the emission point of the laser generator 42 and the emission point of the refractometer 43 intersects with the connection line between the emission point of the monochromatic light generator 41 and the photometer 44. Preferably, in order to further accelerate the detection speed, the volume of the part of the solution level in the reactor 25 that is higher than the connection line between the emission point of the monochromatic light generator 41 and the photometer 44 is greater than 3 cubic centimeters.

[0020] Specifically, the photometer 44 is used to receive the emission signal of the monochromatic light generator 41 and obtain the absorbance of the corresponding solution, so as to feedback the absorbance signal to the main control module 1. The refractometer 45 is used to receive the emission signal of the laser generator 42 and obtain the refractive index of the corresponding solution, so as to feedback the refractive index signal to the main control module 1. Preferably, in other embodiments, in order to further improve the signal propagation effect, the measurement module 4 further includes a signal amplifier. The detection ends of the signal amplifier are respectively connected to the output of the monochromatic light generator 41 and the output end of the laser generator 42, so as to jointly form a test signal with the absorbance signal and the refractive index signal.

[0021] Among them, before preparing the emulsion in the reactor 25, the measurement module 4 first obtains the absorbance signal and the refractive index signal of the solution in the reactor 25 and feeds them back to the main control module 1. The main control module 1 records the absorbance and refractive index at this time as the stable state values. When performing the demulsification degree test, the operator determines the demulsification degree of the corresponding turbine oil by finding the time when the absorbance and refractive index of the emulsion in the test signal obtained by the main control module first return to the stable state values.

[0022] Specifically, the constant temperature device 3 includes: a water bath 31, a heater 32, and a temperature sensor 33. The heater 32, the temperature sensor 33, and the ultrasonic generator 34 are electrically connected to the main control module 1. Under the command of the main control device 1, the heater 32 is powered on to generate heat, so as to heat the aqueous solution in the water bath 31. The temperature sensor 33 controls the magnitude and stop of the heating according to the set temperature value, so as to provide a constant temperature environment for the emulsion in the reactor 27 in the water bath 31.

[0023] To quickly conduct multiple demulsification detection experiments on different turbine oils, a turbine oil demulsification detection device of the present application further includes: a cleaning module 5. Among them, the cleaning module 5 includes: a waste liquid storage tank 51 and an ultrasonic generator 52. The waste liquid storage tank 51 is arranged outside the water bath 31, and the waste liquid storage tank 51 is connected to the reactor 25 through a drain pump 53. The ultrasonic generator 52 is fixedly arranged on the outer bottom surface of the water bath 31, and the ultrasonic generator 52 is controlled by the main control module 1. After the demulsification test is completed, the main control module 1 starts the ultrasonic generator 52 to perform ultrasonic cleaning on the inside of the reactor 25. After the cleaning is completed, the main control module 1 controls the drain pump 53 to extract the solution in the reactor and discharge it into the waste liquid storage tank 51, thereby achieving the purpose of sustainable multiple tests.

[0024] In summary, the present utility model monitors the state of the emulsion in the constant temperature device through the action of the measurement module. After the measurement module feeds back the test signal, the operator can quickly obtain the demulsification degree of the corresponding emulsion according to the feedback time of the monitoring signal recorded by the main control device.
