Description

Technical Field

[0001] The present invention relates to the technical field of lubricating oil detection, and specifically to a lubricity detection device for lubricating oil production. Background Art

[0002] As the "blood" of mechanical equipment, the lubricating performance of lubricating oil directly affects the service life and operation efficiency of the equipment. Currently, a series of indicators such as viscosity, flash point, and anti-wear property are usually used to comprehensively judge the lubricity of lubricating oil. Among them, the viscosity index plays a crucial role in the lubricity of lubricating oil.

[0003] Currently, in factories, a kinematic viscosity meter is usually used to judge the viscosity of lubricating oil. For example, the patents "CN206920280U Kinematic Viscosity Meter" and "CN109342268A A Fast and Fully Automatic Kinematic Viscosity Measuring Device" both disclose a technical solution for liquid viscosity measurement. However, in the actual detection process, air bubbles sometimes mix into the lubricating oil, thereby interfering with the test results. The existing detection devices usually lack effective pretreatment components, resulting in a decrease in detection accuracy. Secondly, after the detection is completed, the cleaning and drying process of the viscosity tube is cumbersome and usually requires special cleaning equipment and drying equipment, which not only increases the equipment occupation space but also improves the maintenance cost. Finally, before detecting the lubricating oil, the viscosity tube usually needs to be installed and calibrated, and the whole process is relatively complex and usually requires professional equipment such as a plumb bob and a level to ensure that the viscosity tube is vertical, which is very inconvenient for non-professional inspectors to use. Summary of the Invention

[0004] The purpose of the present invention is to provide a lubricity detection device for lubricating oil production to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A lubricity detection device for lubricating oil production, the detection device includes a console, a lower end cover, a heat preservation box, and an upper end cover are sequentially arranged above the console, a water bath box is arranged inside the heat preservation box, a temperature adjustment mechanism and a stirring mechanism are arranged inside the water bath box, a fixing mechanism and an installation box are arranged on the upper end cover, the fixing mechanism is detachably installed on the upper end cover through bolts, the installation box is fixedly installed at one end of the upper end cover close to the temperature adjustment mechanism, a viscosity tube is arranged on the fixing mechanism, a pretreatment component is arranged inside the installation box, and before testing the lubricating oil in the viscosity tube, the pretreatment component can effectively remove air bubbles in the lubricating oil to be detected.

[0006] Further, the fixing mechanism includes a first fixing seat, a second fixing seat and a second electromagnet. The second fixing seat is arranged inside the first fixing seat. Two groups of positioning holes are arranged on the second fixing seat, and a group of positioning components are arranged at the side end of each group of positioning holes. An installation groove is arranged at the lower end inside the first fixing seat, and a limiting groove is arranged at the upper end inside the first fixing seat. A limiting block is arranged on the outer side of the second fixing seat, and the limiting block is located in the limiting groove. The limiting block is connected to the limiting groove through a compression spring. The second electromagnet is arranged in the installation groove, and a first magnetic block is arranged on the limiting block.

[0007] When the present invention is working, the staff can first remove the fixing mechanism from the upper end cover and remove the viscosity tube from the fixing mechanism. Then, pour pure water into the water bath tank and turn on the temperature adjustment mechanism and the stirring mechanism. Through the temperature adjustment mechanism and the stirring mechanism, the water temperature in the water bath tank can quickly reach the required temperature. Then, the staff adds the lubricating oil to be tested into the viscosity tube. When ready, insert both ends of the viscosity tube into the two groups of positioning holes, and fix the viscosity tube in the fixing mechanism through the two groups of positioning components. After that, the staff can put the viscosity tube into the water bath tank and fix the fixing mechanism on the upper end cover through bolts. According to the number of bubbles in the lubricating oil, the staff can connect the pretreatment component to the viscosity tube and turn on the pretreatment component at the same time. Through the pretreatment component, the viscosity tube is in a vacuum state to remove the bubbles in the lubricating oil to be tested. When the bubbles in the lubricating oil are removed, the staff can intermittently turn on the second electromagnet (the length of the time to turn on is determined by the staff according to needs). Through the second electromagnet, the second fixing seat can make a reciprocating lifting movement in the first fixing seat. At this time, the lubricating oil in the viscosity tube will vibrate slightly, so as to accelerate the heat exchange between the lubricating oil to be tested and the surrounding environment. When the temperature of the lubricating oil reaches equilibrium with the water temperature in the water bath tank, the staff can continuously turn on the second electromagnet and generate a magnetic field that attracts the first magnetic block through the second electromagnet. Fix the second fixing seat firmly in the first fixing seat through the second electromagnet to prevent the viscosity tube from shaking due to the external environment during the detection of the lubricating oil. When detecting the lubricating oil in the viscosity tube, the staff needs to separate the pretreatment component from the viscosity tube, and then suck the lubricating oil in the viscosity tube into the upper scale line position through a suction ball. By recording the time for the lubricating oil to flow through the two scale lines of the viscosity tube, calculate the viscosity of the lubricating oil, so as to indirectly judge whether the lubricity of the lubricating oil is qualified (the specific detection steps are common knowledge in the field and will not be described in detail here). Compared with the capillary fixture used in the current detection device, the fixing mechanism in the present invention can, on the one hand, fix the viscosity tube, and on the other hand, when the viscosity tube is placed in the water bath tank, the fixing mechanism can accelerate the temperature of the lubricating oil in the viscosity tube to be consistent with the water temperature in the water bath tank, thereby improving the detection efficiency.

[0008] Further, the positioning assembly includes a positioning groove and a positioning frame. There are two groups of positioning frames, which are relatively arranged at the side ends of the positioning holes. One group of positioning grooves is provided on the side of each group of positioning frames away from the positioning holes. One group of telescopic spring rods is provided in each group of positioning grooves, and each group of telescopic spring rods is fixedly connected to one group of positioning frames. At the middle position inside the second fixing seat, there is a first electromagnet and a liquid storage tank. In the liquid storage tank, there is a piston and hydraulic oil. A second magnetic block is provided on the piston. The liquid storage tank is communicated with the positioning groove through an infusion channel. In the present invention, the movement of the piston is controlled by the first electromagnet. When both ends of the viscosity tube are inserted into the two groups of positioning holes, a magnetic force that repels the second magnetic block is generated by the first electromagnet. At this time, the piston will squeeze the hydraulic oil in the liquid storage tank into the positioning grooves in the two groups of positioning assemblies. Under the action of hydraulic pressure, the positioning frames in the two groups of positioning assemblies will generate a clamping force on the viscosity tube, so as to achieve the purpose of fixing the viscosity tube. Compared with the current methods of fixing the viscosity tube, on the one hand, the present invention has a faster fixing speed, and on the other hand, it can effectively ensure that the two groups of corresponding positioning frames move the same distance, ensuring that the center line of the viscosity tube is aligned with the center line of the positioning hole, and reducing the probability of the viscosity tube not being perpendicular to the control console.

[0009] Further, at one end of each group of positioning frames close to the positioning hole, there is a group of calibration units, and the calibration units are used to judge whether the center line of the viscosity tube is aligned with the center line of the positioning hole.

[0010] Further, the calibration unit includes induction blocks and piezoelectric wafers. There are two groups of induction blocks, which are respectively arranged at the upper and lower ends of the positioning frame. One group of piezoelectric wafers is provided on the side of each group of induction blocks away from the positioning hole. Each group of induction blocks is connected to the piezoelectric wafer through an induction spring. The straight line formed by the two groups of induction blocks is in the same plane and parallel to the center line of the positioning hole.

[0011] Further, when the positioning frame in the present invention contacts the outer wall of the viscosity tube, the induction block will first contact the viscosity tube. At this time, the induction spring will deform due to compression, and at the same time, the piezoelectric wafer will generate a group of electrical signals. Finally, since the straight line formed by the two groups of induction blocks on the positioning frame is in the same plane and parallel to the center line of the positioning hole, therefore, when the center line of the viscosity tube is aligned with the center line of the positioning hole, the two piezoelectric wafers will generate the same electrical signal. On the contrary, when the center line of the viscosity tube is not aligned with the center line of the positioning hole, the electrical signals generated by the two piezoelectric wafers will be different. Through the above technical solution, the present invention can timely judge whether the position of the viscosity tube is normal without relying on professional equipment such as plumb bobs and spirit levels, thereby reducing the complexity of the operation and facilitating non-professional inspectors to detect the lubricating oil.

[0012] Further, a cleaning assembly is also provided in the installation box, and the viscosity tube is cleaned and dried through the cooperation of the cleaning assembly and the pretreatment assembly.

[0013] Further, the pretreatment component includes a fan, a first valve, a second valve, a first hose and a second hose. Sealing caps are provided at one ends of the first hose and the second hose extending out of the installation box. The first hose is communicated with the second valve. The second hose is communicated with the first valve and the second valve through a connector. The fan is communicated with the first valve. Before detecting the lubricating oil in the viscosity tube in the present invention, the staff can fix the sealing caps provided at one ends of the first hose and the second hose extending out of the installation box at both ends of the viscosity tube. The remaining ports on the viscosity tube can be blocked manually. Then, the staff can turn on the fan to evacuate the viscosity tube through the fan, so as to remove the bubbles in the lubricating oil to be detected.

[0014] Further, the cleaning component includes a liquid pump, an exhaust pipe and a drain pipe. The first valve is a three-way valve, and the second valve is a four-way valve. One end of the first valve is communicated with the fan. The other two ends of the first valve are respectively communicated with the connector and the drain pipe. One end of the second valve is communicated with the liquid pump. The other three ends of the second valve are respectively communicated with the exhaust pipe, the first hose and the connector.

[0015] Further, the temperature adjustment mechanism includes a heat conduction cylinder, a heating unit and a heat exchange cylinder. The heat exchange cylinder is arranged inside the heat conduction cylinder. The heating unit is arranged between the heat conduction cylinder and the heat exchange cylinder. The pure water in the water bath box is heated through the heating unit. One end of the heat exchange cylinder is communicated with the fan through a second conduit. The other end of the heat exchange cylinder is communicated with the external environment through a first air duct.

[0016] After the detection of the lubricating oil in the present invention is completed, the staff can connect the liquid inlet end of the liquid pump to an external cleaning system and connect the drain pipe to an external waste liquid recovery system. Then, fix the sealing caps on the first hose and the second hose at both ends of the viscosity tube. Manually block the remaining ports on the viscosity tube. Finally, adjust the communication states of the first valve and the second valve so that the first hose is communicated with the liquid pump and the second hose is communicated with the drain pipe. At this time, the liquid pump will transport the cleaning liquid in the external cleaning system along the second valve, the first hose, the viscosity tube, the second hose and the drain pipe, and clean the viscosity tube through the cleaning liquid transported by the liquid pump. When the cleaning of the viscosity tube is completed, the staff can turn off the liquid pump and then change the communication states of the first valve and the second valve so that the second hose is communicated with the fan and the first hose is communicated with the exhaust pipe. At this time, the hot air in the heat exchange cylinder can flow along the first valve, the second hose, the viscosity tube, the first hose and the exhaust pipe through the fan, so as to achieve the purpose of drying the viscosity tube.

[0017] Further, a baffle is provided inside the heat exchange cylinder. The baffle can extend the flow path of the external ambient air inside the heat exchange cylinder, thereby ensuring that the temperature of the external ambient air meets the standard when it flows out of the heat exchange cylinder. A heat-conducting medium is filled between the heat-conducting cylinder and the heat exchange cylinder. Through the heat-conducting medium, the heat generated by the heating unit can be conveniently transferred to the water bath or inside the heat exchange cylinder.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows: Compared with the current detection device, the present invention is provided with a pretreatment component and a cleaning component. Before testing the lubricating oil in the viscosity tube, the pretreatment component can effectively remove the bubbles in the lubricating oil to be detected, thereby improving the detection accuracy, avoiding unstable flow of the lubricating oil during the detection process, generating abnormal phenomena, and interfering with the test results. After the lubricating oil detection is completed, the present invention can directly clean the viscosity tube through the cooperation of the cleaning component and the pretreatment component, and at the same time dry the inner wall of the viscosity tube with the heat of the temperature adjustment mechanism. Compared with the current special cleaning equipment and drying equipment for cleaning and drying the viscosity tube, the present invention can significantly improve the operation efficiency, reduce the equipment occupation space, and reduce the maintenance cost. Through the integrated design, the automation level and reliability of the detection process are further improved. The present invention is also provided with a fixing mechanism. Compared with the capillary fixture used in the current detection device, the fixing mechanism on the one hand serves the purpose of fixing the viscosity tube, and on the other hand, when the viscosity tube is placed in the water bath, the fixing mechanism can accelerate the lubricating oil in the viscosity tube to be consistent with the water temperature in the water bath, thereby improving the detection efficiency. Finally, the present invention is provided with a positioning component and a calibration unit in the fixing mechanism. Through the positioning component, the fixing speed is increased on the one hand, and on the other hand, it can effectively ensure that the center line of the viscosity tube is aligned with the center line of the positioning hole, reducing the probability of the viscosity tube not being perpendicular to the console. Through the calibration unit, the staff can timely judge whether the position of the viscosity tube is normal without the help of professional equipment such as a plumb bob and a spirit level, thereby reducing the complexity of the operation and facilitating non-professional inspectors to detect the lubricating oil.

Specific embodiments

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0029] Embodiment: As Figures 1 - 8 shown, the present invention provides a technical solution, a lubricity detection device for lubricating oil production. The detection device includes a control console 1. Above the control console 1, a lower end cover 2, a heat preservation box 6 and an upper end cover 5 are sequentially arranged. Inside the heat preservation box 6, there is a water bath box 7. Inside the water bath box 7, there is a temperature adjustment mechanism 9 and a stirring mechanism. On the upper end cover 5, there is a fixing mechanism 3 and an installation box 4. The fixing mechanism 3 is detachably installed on the upper end cover 5 through bolts. The installation box 4 is fixedly installed at one end of the upper end cover 5 close to the temperature adjustment mechanism 9. A viscosity tube 8 is arranged on the fixing mechanism 3. A pretreatment component is arranged inside the installation box 4. Before testing the lubricating oil in the viscosity tube 8, the pretreatment component can effectively remove the bubbles in the lubricating oil to be detected.

[0030] As Figures 2 - 4As shown, the fixing mechanism 3 includes a first fixing base 31, a second fixing base 32, and a second electromagnet 33. The second fixing base 32 is arranged inside the first fixing base 31. Two groups of positioning holes 325 are arranged on the second fixing base 32. A group of positioning components are arranged at the side end of each group of positioning holes 325. An installation groove is arranged at the lower end inside the first fixing base 31, and a limiting groove is arranged at the upper end inside the first fixing base 31. A limiting block 321 is arranged on the outer side of the second fixing base 32. The limiting block 321 is located in the limiting groove, and the limiting block 321 is connected to the limiting groove through a compression spring. The second electromagnet 33 is arranged in the installation groove, and a first magnetic block is arranged on the limiting block 321.

[0031] When the present invention is in operation, the staff can first remove the fixing mechanism 3 from the upper end cover 5 and then remove the viscosity tube 8 from the fixing mechanism 3. Next, pour pure water into the water bath tank 7 and turn on the temperature adjusting mechanism 9 and the stirring mechanism. Through the temperature adjusting mechanism 9 and the stirring mechanism, the water temperature in the water bath tank 7 can quickly reach the required temperature. Then, the staff adds the lubricating oil to be tested into the viscosity tube 8. When everything is ready, insert both ends of the viscosity tube 8 into the two sets of positioning holes 325, and fix the viscosity tube 8 in the fixing mechanism 3 through the two sets of positioning components. After that, the staff can put the viscosity tube 8 into the water bath tank 7 and fix the fixing mechanism 3 on the upper end cover 5 with bolts. According to the number of bubbles in the lubricating oil, the staff can connect the pretreatment component to the viscosity tube 8 and turn on the pretreatment component at the same time. Through the pretreatment component, the viscosity tube 8 is in a vacuum state to remove the bubbles in the lubricating oil to be tested. When the bubbles in the lubricating oil are removed, the staff can intermittently turn on the second electromagnet 33 (the length of the time of turning on is determined by the staff according to needs). Through the second electromagnet 33, the second fixing seat 32 can make a reciprocating lifting movement in the first fixing seat 31. At this time, the lubricating oil in the viscosity tube 8 will vibrate slightly, so as to accelerate the heat exchange between the lubricating oil to be tested and the surrounding environment. When the temperature of the lubricating oil reaches equilibrium with the water temperature in the water bath tank 7, the staff can continuously turn on the second electromagnet 33 and generate a magnetic field that attracts the first magnetic block through the second electromagnet 33, and fix the second fixing seat 32 firmly in the first fixing seat 31 through the second electromagnet 33 to prevent the viscosity tube 8 from shaking due to the external environment during the detection of the lubricating oil. When detecting the lubricating oil in the viscosity tube 8, the staff needs to separate the pretreatment component from the viscosity tube 8, and then suck the lubricating oil in the viscosity tube 8 to the upper scale line position with a suction ball. By recording the time for the lubricating oil to flow through the two scale lines on the viscosity tube 8, calculate the viscosity of the lubricating oil, and indirectly judge whether the lubricity of the lubricating oil is qualified (the specific detection steps are common knowledge in the art and will not be described in detail here). Compared with the capillary fixture used in the current detection device, on the one hand, the fixing mechanism 3 in the present invention serves the purpose of fixing the viscosity tube 8. On the other hand, after the viscosity tube 8 is placed in the water bath tank 7, through the fixing mechanism 3, the lubricating oil in the viscosity tube 8 can be accelerated to be consistent with the water temperature in the water bath tank 7, thereby improving the detection efficiency.

[0032] As Figures 4 - 6As shown in the figure, the positioning component includes a positioning groove 327 and a positioning bracket 328. There are two sets of positioning brackets 328, which are relatively arranged at the side ends of the positioning holes 325. One set of positioning grooves 327 is provided on the side of each set of positioning brackets 328 away from the positioning holes 325. One set of telescopic spring rods is provided in each set of positioning grooves 327, and each set of telescopic spring rods is fixedly connected to one set of positioning brackets 328. At the middle position inside the second fixing base 32, there is a first electromagnet 322 and a liquid storage tank 324. A piston 323 and hydraulic oil are provided in the liquid storage tank 324. A second magnetic block is provided on the piston 323. The liquid storage tank 324 is communicated with the positioning groove 327 through a liquid delivery channel 326. In the present invention, the movement of the piston 323 is controlled by the first electromagnet 322. When both ends of the viscosity tube 8 are inserted into the two sets of positioning holes 325, a magnetic force that repels the second magnetic block is generated by the first electromagnet 322. At this time, the piston 323 will squeeze the hydraulic oil in the liquid storage tank 324 into the positioning grooves 327 in the two sets of positioning components. Under the action of the hydraulic pressure, the positioning brackets 328 in the two sets of positioning components will generate a clamping force on the viscosity tube 8, so as to achieve the purpose of fixing the viscosity tube 8. Compared with the current method of fixing the viscosity tube 8, on the one hand, the present invention has a faster fixing speed, and on the other hand, it can effectively ensure that the two sets of corresponding positioning brackets 328 move the same distance, ensuring that the center line of the viscosity tube 8 is aligned with the center line of the positioning hole 325, and reducing the probability that the viscosity tube 8 is not perpendicular to the control console 1.

[0033] As Figures 4 - 6 shown, one set of calibration units is provided at one end of each set of positioning brackets 328 close to the positioning holes 325, and the calibration units are used to judge whether the center line of the viscosity tube 8 is aligned with the center line of the positioning holes 325.

[0034] As Figures 5 - 6 shown, the calibration unit includes induction blocks 3281 and piezoelectric wafers 3282. There are two sets of induction blocks 3281, which are respectively arranged at the upper and lower ends of the positioning brackets 328. One set of piezoelectric wafers 3282 is provided on the side of each set of induction blocks 3281 away from the positioning holes 325. Each set of induction blocks 3281 is connected to the piezoelectric wafer 3282 through an induction spring. The straight line formed by the two sets of induction blocks 3281 is in the same plane as and parallel to the center line of the positioning hole 325.

[0035] When the positioning bracket 328 in the present invention comes into contact with the outer wall of the viscosity tube 8, the induction block 3281 will come into contact with the viscosity tube 8 first. At this time, the induction spring will deform due to compression, and at the same time, the piezoelectric sheet 3282 will generate a set of electrical signals. Finally, since the straight line formed by the two groups of induction blocks 3281 on the positioning bracket 328 and the center line of the positioning hole 325 are in the same plane and parallel, therefore, when the center line of the viscosity tube 8 is aligned with the center line of the positioning hole 325, the two piezoelectric sheets 3282 will generate the same electrical signals. On the contrary, when the center line of the viscosity tube 8 is not aligned with the center line of the positioning hole 325, the electrical signals generated by the two piezoelectric sheets 3282 will be different. Through the above technical solution, the present invention can timely judge whether the position of the viscosity tube 8 is normal without relying on professional equipment such as plumb bobs and spirit levels, thereby reducing the complexity of the operation and facilitating non-professional inspectors to detect lubricating oil.

[0036] As Figure 2 、 Figures 7 - 8 shown, a cleaning component is further provided in the installation box 4, and the viscosity tube 8 is cleaned and dried through the cooperation of the cleaning component and the pretreatment component.

[0037] As Figure 2 、 Figures 7 - 8 shown, the pretreatment component includes a blower 41, a first valve 42, a second valve 44, a first hose 46 and a second hose 47. Sealing caps are provided at one ends of the first hose 46 and the second hose 47 extending out of the installation box 4. The first hose 46 is communicated with the second valve 44, and the second hose 47 is communicated with the first valve 42 and the second valve 44 through a connector 471. The blower 41 is communicated with the first valve 42. Before detecting the lubricating oil in the viscosity tube 8 in the present invention, the staff can fix the sealing caps provided at one ends of the first hose 46 and the second hose 47 extending out of the installation box 4 at both ends of the viscosity tube 8, and the remaining ports on the viscosity tube 8 can be blocked manually. Then, the staff can turn on the blower 41 to evacuate the viscosity tube 8 through the blower 41 to remove the bubbles in the lubricating oil to be detected.

[0038] As Figure 2 、 Figures 7 - 8 shown, the cleaning component includes a liquid pump 43, an exhaust pipe 45 and a drain pipe 48. The first valve 42 is a three-way valve, and the second valve 44 is a four-way valve. One end of the first valve 42 is communicated with the blower 41, and the other two ends of the first valve 42 are respectively communicated with the connector 471 and the drain pipe 48. One end of the second valve 44 is communicated with the liquid pump 43, and the other three ends of the second valve 44 are respectively communicated with the exhaust pipe 45, the first hose 46 and the connector 471.

[0039] As Figure 8As shown in the figure, the temperature adjustment mechanism 9 includes a heat conduction cylinder 91, a heating unit 92, and a heat exchange cylinder 95. The heat exchange cylinder 95 is arranged inside the heat conduction cylinder 91, and the heating unit 92 is arranged between the heat conduction cylinder 91 and the heat exchange cylinder 95. The pure water in the water bath tank 7 is heated by the heating unit 92. One end of the heat exchange cylinder 95 is connected to the fan 41 through a second conduit 94, and the other end of the heat exchange cylinder 95 is connected to the external environment through a first air duct 93.

[0040] After the detection of the lubricating oil in the present invention is completed, the staff can connect the liquid inlet end of the liquid pump 43 to an external cleaning system, connect the drain pipe 48 to an external waste liquid recovery system, then fix the sealing caps on the first hose 46 and the second hose 47 at both ends of the viscosity tube 8, manually block the remaining ports on the viscosity tube 8, and finally adjust the connection states of the first valve 42 and the second valve 44 so that the first hose 46 is connected to the liquid pump 43 and the second hose 47 is connected to the drain pipe 48. At this time, the liquid pump 43 will transport the cleaning liquid in the external cleaning system along the second valve 44, the first hose 46, the viscosity tube 8, the second hose 47, and the drain pipe 48, and the viscosity tube 8 is cleaned by the cleaning liquid transported by the liquid pump 43; after the viscosity tube 8 is cleaned, the staff can turn off the liquid pump 43, and then change the connection states of the first valve 42 and the second valve 44 so that the second hose 47 is connected to the fan 41 and the first hose 46 is connected to the exhaust pipe 45. At this time, the hot air in the heat exchange cylinder 95 can flow along the first valve 42, the second hose 47, the viscosity tube 8, the first hose 46, and the exhaust pipe 45 through the fan 41, thereby achieving the purpose of drying the viscosity tube 8.

[0041] As Figure 8 As shown in the figure, a baffle is arranged inside the heat exchange cylinder 95. The baffle can extend the flow path of the external environment air in the heat exchange cylinder 95, so as to ensure that the temperature of the external environment air meets the standard when flowing out of the heat exchange cylinder 95. A heat conduction medium is filled between the heat conduction cylinder 91 and the heat exchange cylinder 95. Through the heat conduction medium, the heat generated by the heating unit 92 can be conveniently transferred to the water bath tank 7 or the heat exchange cylinder 95.

[0042] Working principle of the present invention: Before working, remove the fixing mechanism 3 from the upper end cover 5 and remove the viscosity tube 8 from the fixing mechanism 3. Then pour pure water into the water bath tank 7, and make the water temperature in the water bath tank 7 reach the required temperature through the temperature adjustment mechanism 9 and the stirring mechanism. When the lubricating oil to be tested is added to the viscosity tube 8, insert both ends of the viscosity tube 8 into two groups of positioning holes 325, and fix the viscosity tube 8 in the fixing mechanism 3 through two groups of positioning components. Detect whether the center line of the viscosity tube 8 is aligned with the center line of the positioning hole 325 through the calibration unit. If the position of the viscosity tube 8 is qualified, the staff can put the viscosity tube 8 into the water bath tank 7 and fix the fixing mechanism 3 on the upper end cover 5 through bolts. Then connect the pretreatment component to the viscosity tube 8, and remove the bubbles in the lubricating oil to be tested through the pretreatment component. Then the staff can intermittently turn on the second electromagnet 33 as needed to accelerate the lubricating oil in the viscosity tube 8 to reach the same temperature as the water temperature in the water bath tank 7. When the temperature of the lubricating oil reaches equilibrium with the water temperature in the water bath tank 7, fix the second fixing seat 32 firmly in the first fixing seat 31 through the second electromagnet 33. When detecting the lubricating oil in the viscosity tube 8, the staff needs to separate the pretreatment component from the viscosity tube 8, and then suck the lubricating oil in the viscosity tube 8 into the upper marking position through a suction ball. By recording the time for the lubricating oil to flow through two scale lines on the viscosity tube 8, calculate the viscosity of the lubricating oil, and indirectly judge whether the lubricity of the lubricating oil is qualified. After the lubricating oil detection is completed, clean and dry the viscosity tube 8 through the cooperation of the cleaning component and the pretreatment component.
