Description

Technical Field

[0001] The utility model belongs to the technical field of petroleum kinematic viscosity test, and particularly relates to a petroleum kinematic viscosity test device. Background Technique

[0002] The kinematic viscosity of petroleum is an important index to measure the fluidity of petroleum products. The kinematic viscosity of petroleum products is widely used to measure liquid petroleum products such as jet fuel oil, diesel oil, lubricating oil, etc. In practical applications, viscosity is of great significance for the quality identification and determination of the use of petroleum products. If the viscosity is large, the oil film thickness is large and the lubrication performance is good, but if the viscosity is too large, the frictional resistance will increase and resources will be wasted. On the contrary, if the viscosity is too small, an insufficient oil film cannot be formed, increasing friction and damaging the machinery.

[0003] In the actual production process, the existing petroleum viscosity test device is large in volume and cannot be carried. It often conducts tests at a designated location. Moreover, when the existing viscosity detection device is in use, the mucus may be uneven, and the mucus in the container is not easy to flow out after the experiment, resulting in troublesome cleaning. Content of the Utility Model

[0004] The purpose of the utility model is to provide a petroleum kinematic viscosity test device in order to solve the problem that the existing petroleum kinematic viscosity test device is relatively bulky and not easy to carry.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme: a petroleum kinematic viscosity test device, including a housing, a test barrel, a motor, a stirring core and a test mechanism. The interior of the housing is a hollow structure, and a power bin and a control bin are arranged at the bottom of the housing. The test barrel is installed in the housing, and the test barrel is a hollow double-layer structure. An air ring is installed in the double-layer structure of the test barrel. The motor is installed in the power bin, the stirring core is installed in the test barrel, the motor drives the stirring core, the test mechanism is installed in the control bin, and the test mechanism is connected to the air ring.

[0011] Both the outer shell and the bottom of the test barrel are provided with sewage outlets, and plug heads are provided at the sewage outlets, and threads are provided on both the sewage outlets and the plug heads.

[0012] As a further description of the above technical solution:

[0013] A sealing ring is provided at the end face connection of the sewage outlet and the plug head.

[0014] As a further description of the above technical solution:

[0015] The test mechanism includes a control board and a micro-pressure sensor. The control board is installed in the control chamber, and the micro-pressure sensor is installed on the control board.

[0016] As a further description of the above technical solution:

[0017] The air ring is provided with a ventilation hole, and the ventilation hole is connected to the micro-pressure sensor through a trachea.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are as follows:

[0019] 1. In the present utility model, the stirring core is rotated by the motor, and the rotation of the stirring core drives the movement of the petroleum in the test barrel. The movement of the petroleum generates pressure on the inner wall of the test barrel, causing the pressure of the air ring in the test barrel to change. The test mechanism statistically analyzes, compares, and analyzes the change data of the pressure in the air ring to determine the kinematic viscosity of the petroleum, realizing the miniaturization of the petroleum kinematic viscosity test device.

[0020] 2. In the present utility model, through the multiple mesh holes provided on the inner wall of the test barrel, the pressure received by the inner wall of the test barrel acts on the air ring through the mesh holes. The air pressure in the air ring changes due to the acting force, and the air pressure in the air ring is transmitted to the micro-pressure sensor through the ventilation hole at the bottom of the air ring and the trachea connected to the ventilation hole.

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 shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-4 , the present invention provides a technical solution: an apparatus for testing the kinematic viscosity of petroleum, including an outer shell 1, a test barrel 2, a motor 3, a stirring core 4 and a testing mechanism 5. The interior of the outer shell 1 is a hollow structure, and a power bin 6 and a control bin 7 are provided at the bottom of the outer shell 1. The test barrel 2 is installed in the outer shell 1, and the test barrel 2 is a hollow double-layer structure. An air ring 8 is installed in the double-layer structure of the test barrel 2. The motor 3 is installed in the power bin 6, the stirring core 4 is installed in the test barrel 2, the motor 3 drives the stirring core 4, the testing mechanism 5 is installed in the control bin 7, and the testing mechanism 5 is connected to the air ring 8. By driving the stirring core 4 to rotate by the motor 3, the rotation of the stirring core 4 drives the petroleum in the test barrel 2 to move. The movement of the petroleum generates pressure on the inner wall of the test barrel 2, causing the pressure of the air ring 8 in the test barrel 2 to change. The testing mechanism 5 statistically analyzes, compares and analyzes the change data of the pressure in the air ring 8 to determine the kinematic viscosity of the petroleum, realizing the miniaturization of the apparatus for testing the kinematic viscosity of petroleum;

[0029] A plurality of mesh holes 9 arranged in an array are formed on the inner wall of the test barrel 2, which is conducive to the petroleum in the test barrel 2 contacting the air ring 8 through the mesh holes 9;

[0030] The motor 3 is a magnetic induction motor, which is convenient for the disassembly, assembly and cleaning of the stirring core 4;

[0031] Drain ports 10 are provided at the bottoms of both the outer shell 1 and the test barrel 2. A plug 11 is provided at the drain port 10, and threads 17 are provided on both the drain port 10 and the plug 11, which is convenient for the plug 11 to be installed on the drain port 10 by screwing;

[0032] A sealing ring 12 is provided at the end face connection of the drain port 10 and the plug 11 to ensure the sealing between the drain port 10 and the plug 11;

[0033] The test mechanism 5 includes a control board 13 and a micro-pressure sensor 14. The control board 13 is installed in the control bin 7, and the micro-pressure sensor 14 is installed on the control board 13. The micro-pressure sensor 14 collects data on the pressure exerted on the gas ring 8 when the petroleum moves in the test barrel 2. The control board 13 statistically analyzes, compares, and analyzes the collected data.

[0034] The gas ring 8 is provided with a vent hole 15. The vent hole 15 is connected to the micro-pressure sensor 14 through a trachea 16. The vent hole 15 transmits the pressure exerted on the gas ring 8 due to the stirring of the petroleum in the test barrel 2 to the micro-pressure sensor 14 through the trachea 16.

[0035] Working principle: First, pour the petroleum whose kinematic viscosity needs to be tested into the test barrel 2. Second, the motor 3 located in the power bin 6 drives the stirring core 4 located in the test barrel 2 to rotate. The stirring core 4 rotates to stir the petroleum in the test barrel 2. The moving petroleum squeezes the inner wall of the test barrel 2. A plurality of mesh holes 9 are provided on the inner wall of the test barrel 2. The pressure exerted on the inner wall of the test barrel 2 acts on the gas ring 8 through the mesh holes 9. The air pressure in the gas ring 8 changes due to the acting force. The pressure in the gas ring 8 is transmitted to the micro-pressure sensor 14 through the vent hole 15 at the bottom of the gas ring 8 and the trachea 16 connected to the vent hole 15. The micro-pressure sensor 14 collects the data, and the control board 13 statistically analyzes, compares, and analyzes the data collected by the micro-pressure sensor 14 to determine the kinematic viscosity of the petroleum, realizing the miniaturization of the petroleum kinematic viscosity test device. Second, sewage outlets 10 are provided at the bottom of both the outer shell 1 and the test barrel 2. By rotating and removing the plug 11 screwed onto the sewage outlet 10, the petroleum whose viscosity has been tested can be discharged from the test barrel 2. Finally, since the motor 3 drives the stirring core 4 in a magnetic induction manner, the stirring core 4 can also be taken out of the test barrel 2 for cleaning. While realizing the miniaturization of the petroleum kinematic viscosity test device, it is also convenient for cleaning the test barrel 2 after the test.
