Description

A foaming tendency detection device Technical Field

[0001] This utility model relates to the field of foaming tendency detection technology, and more specifically to a foaming tendency detection device. Background Technology

[0002] Lubricating oil is an industrial oil used to reduce mechanical friction, lower wear, cool, and protect mechanical parts. During equipment operation, lubricating oil comes into contact with air. For example, in a gearbox, the high-speed rotation of gears causes lubricating oil to splash, entraining a large amount of air into the oil. In hydraulic systems, if air is drawn in when the oil pump draws in oil, it will also cause air to mix into the lubricating oil, leading to foam formation. Foam reduces lubrication performance, accelerates oil oxidation, deteriorates lubricating oil properties, and produces acidic substances, gums, and deposits, shortening the service life of the lubricating oil. Therefore, foaming tendency testing can assess the likelihood and stability of foam formation during lubricating oil use, allowing for the selection of suitable lubricating oil and the implementation of appropriate measures to prevent or reduce foam formation, ensuring the safe and stable operation of equipment.

[0003] Existing foaming tendency detection devices generally use a stirrer in the lubricating oil sample to agitate the lubricating oil at a certain speed and time. During the agitation process, air is entrained into the lubricating oil, forming bubbles, thus simulating the situation where air is mixed into the lubricating oil due to mechanical agitation during equipment operation, such as the lubricating oil foaming tendency detection device with prior art publication number CN220552854U.

[0004] However, the existing technology described above still has the following problems when in use: after the lubricating oil is tested using the detection device, a small amount of lubricating oil will remain in the detection cylinder due to the viscosity of the lubricating oil. Because the diameter of the detection cylinder is small, the testing personnel need to spend a lot of time cleaning it, affecting the testing efficiency. Based on this, the present invention provides a foaming tendency detection device that is easy to clean. Summary of the Invention

[0005] To overcome the aforementioned deficiencies in the prior art, this utility model provides a foaming tendency detection device. A driving mechanism drives a stirring paddle to rotate and stir the lubricating oil in a transparent measuring cylinder, simulating the situation where air is mixed into the lubricating oil due to mechanical agitation during equipment operation. The foaming tendency of the lubricating oil is assessed by measuring the volume or height of the foam. An electric push rod drives a scraper downwards, thereby assisting the testing personnel in cleaning the lubricating oil in the transparent measuring cylinder and preventing lubricating oil residue from affecting the accuracy of subsequent tests, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a foaming tendency detection device, comprising a base, a transparent measuring cylinder fixedly mounted on the top of the base, a stirring paddle disposed inside the transparent measuring cylinder, a scraper sleeved on the top of the outer wall of the stirring paddle, a base plate rotatably mounted on the bottom of the outer wall of the stirring paddle, a driving mechanism fixedly mounted on the top of the stirring paddle, a rubber sealing ring disposed between the base plate and the transparent measuring cylinder, multiple heating plates fixedly mounted on the outer wall of the transparent measuring cylinder, a top plate fixedly mounted on the top of the base, a bracket fixedly mounted on the bottom of the base, and the driving mechanism comprising an electric push rod, the bottom end of the piston rod of the electric push rod being fixed to the top of the stirring paddle.

[0007] In a preferred embodiment, a servo motor is provided on the top of the top plate. The outer wall of the output shaft of the servo motor and the outer wall of the electric push rod are both fixedly fitted with meshing gears. By means of gear transmission, the servo motor drives the electric push rod to rotate automatically through the gears, thereby realizing the automatic rotation and stirring of the stirring paddle.

[0008] In a preferred embodiment, a mounting plate is fixedly sleeved on the outer wall of the servo motor. The mounting plate is detachably connected to the top plate, and the mounting plate is used to support the servo motor, thereby improving the stability of the servo motor.

[0009] In a preferred embodiment, a support plate is fixedly provided at the bottom of the base plate, and an installation hole is provided at the bottom of the base. Both the base plate and the support plate are located in the installation hole. The installation hole is used to limit the position of the support plate, thereby improving the stability of the support plate.

[0010] In a preferred embodiment, the inner wall of the mounting hole is provided with a plurality of fixing holes arranged in a ring array. Each fixing hole is fixed with an electric push rod II. A fixing block is fixed on the piston rod of the electric push rod II. The outer wall surface of the support plate is provided with a number of fixing slots equal to the number of fixing blocks. The fixing blocks are inserted into the fixing slots. The support plate is fixed by the cooperation of the fixing blocks and fixing slots, which can further improve the stability of the base plate.

[0011] In a preferred embodiment, the top of the scraper is fixedly connected to a liquid inlet pipe and an air inlet pipe. The bottom of both the liquid inlet pipe and the air inlet pipe are connected to the inside of the transparent graduated cylinder. Both the liquid inlet pipe and the air inlet pipe are located on one side of the mounting plate. The lubricating oil to be tested is injected into the transparent graduated cylinder through the liquid inlet pipe, and the air inlet pipe enables the air to flow inside the transparent graduated cylinder.

[0012] In a preferred embodiment, both the top of the liquid inlet pipe and the top of the air inlet pipe are threaded with sealing caps. The sealing caps are used to seal the liquid inlet pipe and the air inlet pipe to prevent debris from entering the transparent measuring cylinder and contaminating the lubricating oil.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model uses a drive mechanism to drive a stirring paddle to rotate and stir the lubricating oil in a transparent measuring cylinder, simulating the situation where air is mixed into the lubricating oil due to mechanical agitation during equipment operation. The foaming tendency of the lubricating oil is evaluated by measuring the volume or height of the foam. After the test is completed, an electric push rod is used to drive the scraper to move down, thereby assisting the tester in cleaning the lubricating oil in the transparent measuring cylinder and avoiding lubricating oil residue from affecting the accuracy of subsequent tests.

[0015] 2. By extending the electric push rod, the fixed block is moved. The fixed block is inserted into the fixed groove, which can improve the firmness between the support plate and the base, and thus further improve the stability of the base plate. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Referring to Figures 1-5 in the specification, this utility model provides a foaming tendency detection device, including a base 1. A transparent measuring cylinder 2 is fixedly mounted on the top of the base 1. A stirring paddle 3 is provided inside the transparent measuring cylinder 2. A scraper 4 is sleeved on the top of the outer wall of the stirring paddle 3. A liquid inlet pipe 17 and an air inlet pipe 18 are fixedly passed through the top of the scraper 4. The bottoms of the liquid inlet pipe 17 and the air inlet pipe 18 are connected to the inside of the transparent measuring cylinder 2. The liquid inlet pipe 17 and the air inlet pipe 18 are both located on one side of the mounting plate 64. A sealing cap 19 is threadedly connected to the top of the liquid inlet pipe 17 and the top of the air inlet pipe 18.

[0025] Multiple heating plates 8 are fixedly provided on the outer wall of the transparent measuring cylinder 2, a top plate 9 is fixedly provided on the top of the base 1, and a bracket 10 is fixedly provided on the bottom of the base 1. When the stirring paddle 3, scraper 4, bottom plate 5 and support plate 11 move down together, the bracket 10 supports the base 1, which makes it convenient for the testing personnel to clean the stirring paddle 3, scraper 4, bottom plate 5 and support plate 11.

[0026] The bottom of the outer wall of the stirring paddle 3 is rotatably provided with a base plate 5. A rubber sealing ring 7 is provided between the base plate 5 and the transparent measuring cylinder 2. A support plate 11 is fixedly provided at the bottom of the base plate 5. An installation hole 12 is opened at the bottom of the base 1. Both the base plate 5 and the support plate 11 are located in the installation hole 12.

[0027] A drive mechanism 6 is fixedly mounted on the top of the stirring paddle 3. The drive mechanism 6 includes an electric push rod 61, which is powered by its own battery and does not require an external wire, thus avoiding interference from the external wire. The bottom end of the piston rod of the electric push rod 61 is fixed to the top of the stirring paddle 3. A servo motor 62 is mounted on the top of the top plate 9. Gears 63 that mesh with each other are fixedly fitted on the outer wall of the output shaft of the servo motor 62 and the outer wall of the electric push rod 61. A mounting plate 64 is fixedly fitted on the outer wall of the servo motor 62. The mounting plate 64 is detachably connected to the top plate 9 and supports the servo motor 62, thereby improving the stability of the servo motor 62.

[0028] In actual use, the tester first pours the lubricating oil into the transparent measuring cylinder 2 through the inlet pipe 17. Then, the servo motor 62 drives the electric push rod 61 to rotate through two gears 63. The electric push rod 61 drives the stirring paddle 3 to rotate together. At the same time, the sealing cover 19 on the air inlet pipe 18 is opened. During the stirring process, air is drawn into the lubricating oil by the stirring paddle 3, forming bubbles. This simulates the situation where air is mixed into the lubricating oil due to mechanical agitation during equipment operation. After stirring, the foaming tendency of the lubricating oil is evaluated by measuring the volume or height of the foam. After the test, the electric push rod 61 is extended to drive the stirring paddle 3, scraper 4, base plate 5 and support plate 11 to move down together. The scraper 4 is used to scrape off the residual lubricating oil in the transparent measuring cylinder 2. This also facilitates the cleaning of the stirring paddle 3, scraper 4, base plate 5 and support plate 11, avoiding the impact of residual lubricating oil on the accuracy of subsequent tests.

[0029] Referring to Figures 4-5 of the specification, the inner wall of the mounting hole 12 is provided with a plurality of fixing holes 13 arranged in a ring array.

[0030] By extending the electric push rod 14, the fixed block 15 is moved. The fixed block 15 is inserted into the fixed groove 16, which can improve the firmness between the support plate 11 and the base 1, and thus further improve the stability of the base plate 5.
