Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of petroleum chemical industry, especially a petroleum product kinematic viscosity tester. BACKGROUND

[0002] Petroleum is a naturally occurring liquid composed primarily of hydrocarbons, and is usually black or dark brown. It is formed in the Earth's crust by the decomposition and transformation of organic matter, such as ancient marine organisms. The petroleum product kinematic viscosity tester is an instrument used to measure the kinematic viscosity of petroleum and its derivative products. Kinematic viscosity refers to the internal friction of a fluid when it flows at a certain temperature and pressure, usually expressed in square millimeters per second. Kinematic viscosity is an important parameter for evaluating the flow characteristics and processing performance of petroleum products.

[0003] After searching, it is found that the patent authorized announcement No. CN220729953U discloses a petroleum product kinematic viscosity tester, which comprises a rack, a detection table arranged at the front of the rack, an automatic measuring device arranged above the detection table, and a hydraulic cylinder fixed to the upper inner wall of the detection table. The utility model relates to the technical field of viscosity testers. The petroleum product kinematic viscosity tester drives the rotating shaft to rotate clockwise through the driving motor, the driving gear and the driven gear, thereby pulling the two tension bars to move, so that the two sliding blocks slide towards each other in the bar-shaped groove, and the two folding pressing blocks move towards each other. The automatic measuring device can be installed and fixed through the cooperation of the rubber protection pad. The structure is simple, the automatic measuring device can be clamped quickly, and only one power motor is needed, so the use cost is low. The flushing assembly can be used for flushing the detection table to ensure the cleanliness of the detection table. The device can clean the detection table, but there is no mechanism to treat the liquid after cleaning, which can cause water to accumulate on the detection table and affect the next detection work.

[0026] The connection method can be any existing method, such as bonding, welding, or bolting, depending on the actual needs.

[0027] Please see Figures 1 to 5 As shown, a kinematic viscosity meter for petroleum products includes a workbench 1. An electric telescopic rod 2 is mounted on the top of the workbench 1. The telescopic end of the electric telescopic rod 2 is connected to a petroleum kinematic viscosity meter 3, which is a specialized instrument for measuring the kinematic viscosity of petroleum and its products. Details are omitted here. The workbench 1 contains a motion assembly for treating the liquid generated during rinsing. The motion assembly includes a water tank 15 fixedly installed at the bottom of the workbench 1. The water tank 15 contains a detergent for cleaning petroleum products. A mounting plate 19 is fixedly installed inside the water tank 15. The water tank 19 has symmetrical grooves 20 on both sides, and a limiting plate 21 is symmetrically arranged between the two grooves 20. A filter plate 18 for filtering the washed water is slidably connected in the limiting plate 21. A second door 17 for removing the filter plate 18 is provided on the outside of the water tank 15. One end of a spring 22 is symmetrically connected to both sides of the filter plate 18, and the other end of the spring 22 is connected to a limiting ball 23. A limiting groove adapted to the shape of the limiting ball 23 is opened in the limiting plate 21. The filter plate 18 can be fixed in the limiting plate 21 by the limiting ball 23 and the limiting groove. The filter plate 18 can be replaced by opening the second door 17 and pulling out the filter plate 18.

[0028] The workbench 1 has a placement groove 4. The bottom of the placement groove 4 has symmetrically arranged flow channels 8 for the water to flow down after rinsing. A placement platform 11 is welded and fixed between the two flow channels 8. A first clamping plate 12 is fixedly installed on the top of the placement platform 11. A screw 6 is threaded to one side of the workbench 1. The screw 6 passes through the workbench 1 and is connected to a second clamping plate 14 at its end. A motion track 13 is symmetrically fixedly installed on the top of the placement platform 11. The second clamping plate 14 is slidably connected to the motion track 13. By rotating the screw 6, the second clamping plate 14 slides on the motion track 13, thereby cooperating with the first clamping plate 12 to fix the loading tool containing petroleum products.

[0029] Water outlet pipes 9 are symmetrically arranged on both sides of the placement tank 4. One end of each water outlet pipe 9 is connected to a nozzle 10, and the other end extends into the water inlet tank 15. A pressure valve 16 is installed on the outside of each water outlet pipe 9. The pressure valve 16 is existing equipment and will not be described in detail here. The water outlet pipe 9 is located in the groove 20.

[0030] The electric telescopic rod 2, the petroleum kinematic viscosity meter 3, and the pressure valve 16 are all existing technologies. Their working principles, dimensions, and models are irrelevant to the problem solved by this application, so they will not be described in detail. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the field. Furthermore, this utility model is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail.

[0031] Working principle: The loading tool containing petroleum products is placed between the first clamping plate 12 and the second clamping plate 14. The screw 6 is rotated to fix it. Then, the electric telescopic rod 2 on the worktable 1 adjusts the petroleum kinematic viscosity meter 3 to a suitable height by telescopic movement and then the measurement work is carried out.

[0032] After completion, the pressure valve 16 draws water from the water tank 15 into the water outlet pipe 9 and then sprays it out through the nozzle 10 to clean the loading tool. The rinsed water flows into the flow channel 8 through the placement platform 11 and is then filtered through the filter plate 18. The filtered water then enters the water tank 15 to prepare for the next operation.
