[0002] Lubricating oil is used in mechanical equipment. Different machines are used in different environments and conditions, which will also place the lubricating oil in different environments. In one case, high-temperature steam enters the lubricating oil. When the steam contacts the lubricating oil, it will condense into water, which will then cause the lubricating oil to emulsify. The emulsification of lubricating oil will have hazards such as reducing the lubricating performance, increasing equipment wear, corroding the contacting parts, reducing equipment efficiency, and affecting the equipment life. Therefore, during the production process of lubricating oil, corresponding emulsification measurement is required to ensure the quality of the lubricating oil. However, in existing measuring instruments, the heating structure for generating steam is mostly arranged outside the steam generator, resulting in problems such as low heating efficiency and large heat waste. In addition, during the cooling process of the steam, an external water source is generally required, making it difficult to ensure a constant temperature of the cooling water and prone to wasting water resources. Therefore, a lubricating oil steam emulsification measuring device is needed. Summary of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer to Figure 1 , the lubricating oil steam emulsification tester, including a bottom table 1, a heating component, a low-temperature circulating bath 5, a steam generator 6, an emulsification cylinder 11, a measuring ring 13, a cooling pipe 15 and a graduated cylinder 16. A fixed seat 2 is fixedly installed on the upper surface of the bottom table 1, and there are three fixed seats 2. A fixed vertical rod 3 is fixedly installed at the upper end of each fixed seat 2. The steam generator 6 is assembled on the left fixed vertical rod 3, and the heating component is assembled on the steam generator 6. The emulsification cylinder 11 is assembled on the middle fixed vertical rod 3, and a steam transmission pipe 12 is assembled between the emulsification cylinder 11 and the steam generator 6. The measuring ring 13 is sleeved on the outer wall of the emulsification cylinder 11. The cooling pipe 15 is assembled on the right fixed vertical rod 3, and the cooling pipe 15 is connected to the low-temperature circulating bath 5 through a pipeline. A steam discharge pipe 14 is assembled at the upper end of the emulsification cylinder 11, and the cooling pipe 15 is sleeved on the outside of the steam discharge pipe 14. The graduated cylinder 16 is assembled on the upper surface of the bottom table 1, and the lower end of the steam discharge pipe 14 is located inside the graduated cylinder 16.

[0020] The bottom table 1, the fixed seat 2, etc. are all aluminum products, which improve the overall stability and aesthetics.

[0021] The heating component includes an electric furnace wire 8. The steam generator 6 is composed of an upper spherical container and a lower cylindrical container. The electric furnace wire 8 is assembled in the cylindrical container of the steam generator 6.

[0022] The steam generator 6 needs to be filled with 2L of distilled water and the water level height is marked.

[0023] The electric furnace wire 8 is arranged in the steam generator 6. Compared with heating from the outside, it can better complete the heating work, improve the heating efficiency and reduce the heat loss.

[0024] In addition, a heat insulation layer can be provided on the outer surface of the cylindrical container of the steam generator to further improve the heating efficiency.

[0025] 100 mL of lubricating oil sample is injected into the emulsification cylinder 11, and the lower end of the steam transmission pipe 12 is close to the lowermost end of the inner cavity of the emulsification cylinder 11.

[0026] The temperature of the cooling water in the cooling pipe 15 is 15 - 30 °C. The temperature control is achieved through the low-temperature circulating bath 5. Among them, the temperature of the cooling water can be set, and the temperature stability is achieved through the low-temperature circulating bath 5.

[0027] In actual use, ground joint clamps need to be installed on the steam transmission pipe 12 and the steam discharge pipe 14.

[0028] Specifically, as Figure 1 shown, the heating assembly further includes an electric control box 4 and a junction box 7. The junction box 7 is assembled on the outer wall of the steam generator 6, and the junction box 7 is electrically connected to the electric furnace wire 8. The electric control box 4 is fixedly installed on the upper surface of the base table 1, and the electric control box 4 is electrically connected to the junction box 7.

[0029] The electric control box 4 controls the heating of the electric furnace wire 8 and can control its heating power. By heating the electric furnace wire 8, the distilled water in the steam generator 6 evaporates. The steam enters the lower end in the emulsifying cylinder 11 through the steam transmission pipe 12 and contacts the lubricating oil. Then the steam flows into the steam discharge pipe 14, and under the cooling effect of the cooling water in the cooling pipe 15, the steam condenses into water and finally falls into the measuring cylinder 16.

[0030] Specifically, the electric furnace wire 8 is made of nickel-chromium wire, and the electric furnace wire 8 is located in the steam generator 6, which can improve the heating power and ensure the heating stability.

[0031] Specifically, as Figure 1 shown, one connection end of the connector 9 is assembled at the upper end of the steam generator 6. The steam transmission pipe 12 has three connection ends. The second connection end is connected to the steam transmission pipe 12, and the third connection end is assembled with an air release cock 10.

[0032] Before the distilled water is heated and evaporated, the air release cock 10 needs to be opened to ensure the pressure balance in the steam generator 6.

[0033] After emulsification is completed, the air release cock 10 is opened to interrupt the steam supply.

[0034] Specifically, as Figure 2 shown, a rectangular hole is formed on the outer surface of the measuring ring 13. One side wall of the rectangular hole is provided with a zero scale 131 and a sinking scale 132, and the sinking scale 132 is located below the zero scale 131. The other side wall of the rectangular hole is provided with a rising scale 134. A zero graduation line 133 is formed on the outer surface of the measuring ring 13 below the rectangular hole.

[0035] The distance between the sinking scale 132 and the zero scale 131 is 55 mm, that is, the sinking scale 132 is a 55-mm measurement mark.

[0036] The distance between the rising scale 134 and the zero graduation line 133 is 65 mm, that is, the rising scale 134 is a 65-mm measurement mark.

[0037] Specifically, as Figure 1As shown, interfaces are provided at the upper and lower ends of the cooling pipe 15. The lower interface is the water inlet, and the upper interface is the water outlet. The water inlet and the water outlet are respectively connected to the low-temperature circulating bath 5 through pipelines, so that the cooling water flows upward from bottom to top.

[0038] The usage method of this lubricating oil steam emulsification tester includes preparation work and measurement process. The preparation work is as follows:

[0039] 1. Remove the connector 9, fill the steam generator 6 with 2 L of distilled water, and mark the water level height;

[0040] A total of multiple measurements need to be carried out. After each measurement, the water must be added to the marked water level. After a total of ten measurements, the steam generator needs to be emptied, cleaned, and then refilled with water for use;

[0041] 2. Reinsert the connector 9 and open the air release cock;

[0042] 3. At room temperature (18 - 28 °C), inject 100 mL of the sample into the emulsification cylinder 11, taking care not to wet the cylinder wall above the sample liquid level, and then place the cylinder in a bath at 65 ± 5 °C and heat for at least 15 minutes;

[0043] Before each measurement, the emulsification cylinder 11 and the steam discharge pipe 14 need to be rinsed with toluene, and then rinsed with acetone, concentrated sulfuric acid, and water. The cleaned device is dried in an oven at (105 ± 2) °C;

[0044] 4. Turn on the cooling water system and pass continuous cooling water into the condenser at a temperature of 15 - 30 °C.

[0045] The test process of this lubricating oil steam emulsification tester includes Method 1 and Method 2. Method 1 requires measuring the sedimentation time of the water phase, and Method 2 requires measuring the separation time of the two phases.

[0049] 3. After the water boils and generates steam, rotate the adjustment knob counterclockwise to make the heating power between 750 ± 10 W;

[0050] 4. Then take out the emulsification cylinder 11 from the bath and fix it on the fixed vertical rod 3;

[0051] 5. Preheat the steam transmission pipe 12 to allow steam to pass through the steam transmission pipe 12 for 2 minutes until no continuous water droplets are formed;

[0054] 8. To verify the uniform discharge of steam, measure the volume of the condensed water generated in the graduated cylinder 16 every 5 minutes, and it must reach 205 ± 5 mL after 20 minutes. If the rate is not reached, the heating power can be adjusted. If the volume exceeds this value, reduce the power; otherwise, increase the power;

[0055] 9. Shortly before the end of the steam introduction, push the measuring ring 13 onto the emulsifying cylinder 11 as Figure 3 shown;

[0056] 14. After 20 minutes, interrupt the steam supply by simultaneously opening the air release cock 10 and turning off the power supply. Adjust the zero scale 131 mark of the measuring ring 13 to the interface between the emulsion and the air within at most 2 s after the end of the steam injection, and start the stopwatch;

[0057] 10. Observe the sinking of the aqueous phase in the lubricating oil. When the oil-water phase boundary reaches the sinking scale, read the time from the stopwatch. If the time is less than 1800 seconds, record the measurement time. If the time exceeds 1800 seconds, end the measurement.

[0065] 7. Start timing with a stopwatch from when the steam is introduced into the emulsifying cylinder 11 and continue for 20 minutes under the action of flowing steam;

[0066] 8. To verify the uniform discharge of steam, the volume of the condensed water generated in the graduated cylinder 16 is measured every 5 minutes and must reach 205 ± 5 mL after 20 minutes. If the rate is not reached, the heating power can be adjusted. If the volume exceeds this value, the power is reduced; otherwise, the power is increased.

[0067] 9. Shortly before the end of steam discharge, the measuring ring 13 is pushed onto the emulsifying cylinder 11, as Figure 4 shown, so that the zero graduation line 133 of the measuring ring 13 is in the same plane as the bottom of the inner cavity of the emulsifying cylinder 11.

[0068] After 20 minutes, the steam supply is interrupted by simultaneously opening the air release cock 10 and turning off the power supply, and the stopwatch is started.

[0069] 10. The rise of the aqueous phase in the sample is observed. When the phase boundary between the water and the sample reaches the 65 - millimeter measurement mark, the time is read from the stopwatch. If the time is less than 1800 seconds, the measurement time is recorded. If the time exceeds 1800 seconds, the measurement ends.

[0070] For Method 1 and Method 2, regarding the result representation, the following requirements are as follows:

[0071] 1. The water separation ability, that is, the time required for the sedimentation or separation process, is given in seconds, rounded to the nearest second according to this standard.

[0072] 2. If the water separation ability is less than 30 s, the result should be "30 s"; if the water separation ability exceeds 1800 s, the result must be "1800 s".

[0073] 3. If the lubricating oil has been filtered before the test, the type of filtration must be indicated in the result.

[0074] 4. When rounding to the last digit to be specified, Part 2 of DIN 1333 (the method of expressing numerical data formulated by the German Institute for Standardization) must be considered.

[0075] The above content is only the preferred embodiment of the present utility model. For those of ordinary skill in the art, based on the idea of the present utility model, many changes can be made in the specific implementation manner and application scope.
