Description

Technical Field

[0001] The utility model relates to the technical field of pour point testers, in particular to a constant temperature petroleum product pour point tester. Background Art

[0002] Constant temperature petroleum products are obtained by processing and refining raw petroleum. They are derivatives of petroleum. Constant temperature petroleum products refer to petroleum products that can maintain fixed properties at a certain temperature, such as fuel oil, lubricating oil, etc. These products need to maintain stability at a specific temperature.

[0003] These products require pour point testing, which measures the temperature at which they begin to flow at a preset temperature. This test is designed to determine the product's range of use. If the product's pour point is lower than the ambient temperature, it may not flow properly, causing problems in machinery or equipment. During testing, petroleum products are often contained in containers. After use, manual cleaning is tedious and inconvenient, as most petroleum products are sticky. Therefore, we propose a constant-temperature petroleum product pour point tester to address this issue. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figure 1-Figure 5 As shown, the present invention proposes a constant temperature petroleum product pour point tester, comprising a body 1, a water tank 4, a barrel 5, a cleaning pipe 6, an adjustment frame 9 and a bottom frame 20. A fixed frame 12 is provided above the water tank 4, an adjustment frame 9 is provided inside the fixed frame 12, a rotating shaft 13 rotatably mounted inside the fixed frame 12 is provided at both the front and rear ends of the adjustment frame 9, a motor 8 having an output end connected to the rotating shaft 13 is provided at the front end of the fixed frame 12, a protective shell 24 is provided above the adjustment frame 9, a heating core 3 is provided inside the protective shell 24, a top cover 22 is sleeved on the outer wall of the protective shell 24, and a barrel 5 is provided at the lower end of the top cover 22;

[0022] The front and rear ends of the fixing frame 12 are both provided with support rods 7 that are symmetrically distributed and connected to the water tank 4;

[0023] The body 1 is located on one side of the water tank 4, and a control panel 2 is provided on the inner wall of the upper end of the body 1;

[0024] The regulating frame 9 is provided with symmetrically distributed hydraulic rods 10, and the output end of the hydraulic rods 10 is provided with a clamping plate 11;

[0025] Based on the implementation steps of Example 1: the petroleum product is stored in the barrel 5, and the barrel 5 is threadedly connected to the outer wall of the top cover 22 through the threaded sleeve 23 and fixed to the top cover 22. It is worth noting that the heating core 3 is electrically connected to the body 1 through an electrical connection, and the collective provides power control for the heating core 3. A thermocouple is provided inside the protective shell 24 for temperature detection. The thermocouple heats the inside of the protective shell 24, and the heat source is conducted through the protective shell 24 into the petroleum product inside the barrel 5, and the petroleum product is detected at a set temperature;

[0026] At the same time, after the petroleum product is filled, the hydraulic pressure drives the clamping plate 11 to clamp the barrel 5, and the barrel 5 is clamped and fixed. The barrel 5 is firmly fixed in the adjustment frame 9. When the motor 8 drives the rotating shaft 13 to rotate, the adjustment frame 9 is driven to rotate inside the fixed frame 12, and then the barrel 5 is driven to rotate. After the petroleum product inside the barrel 5 reaches the set temperature, it is observed whether it flows after tilting, so as to understand the pour point measurement of the petroleum product. After the constant temperature product remains stable at a specific temperature, by gradually tilting the barrel 5, when the petroleum product begins to deform or move, this moment is recorded and the pour point temperature is displayed on the control panel 2. The control panel 2 will display the temperature at which the liquid begins to flow, that is, the pour point of the product. This value can be used as an important parameter of the product performance specification. In this way, the pour point meter can accurately measure the pour point temperature of the constant temperature petroleum product, help users understand the behavioral characteristics of the product under different temperature conditions, thereby ensuring the quality and application safety of the product.

[0032] In this embodiment, after the petroleum product inside the barrel 5 is detected, the hydraulic rod 2 16 drives the lifting plate 17, and after the electromagnetic suction cup 14 is energized, it contacts the metal plate 26 to achieve magnetic adsorption of the metal plate 26. At this time, the motor 3 15 is in operation, and the electromagnetic suction cup 14 is driven to rotate through the output shaft. The electromagnetic suction cup 14 applies a rotational force to the metal plate 26, driving the barrel 5 to rotate. At the same time, the hydraulic rod 2 16 drives the motor 3 15 to steadily descend, and the threaded sleeve 23 of the threaded connection between the barrel 5 and the top cover 22 is rotated out from the outer wall of the top cover 22. Then the motor 4 18 drives the bottom The frame 20 rotates and drives the barrel 5 to rotate corresponding to the cleaning tube 6. The hydraulic rod three 30 drives the motor two 29 to move, driving the cleaning tube 6 to be inserted into the barrel 5. The operation of the motor two 29 drives the cleaning tube 6 to rotate. The nozzle one 27 and the nozzle two 28 on the outer wall of the cleaning tube 6 rotate at the same time to flush the side inner wall and the lower inner wall of the barrel 5.
