[0033] The following is combined Figures 1 to 7 The technical solution of this utility model will be further described in detail below.

[0034] This invention can be implemented in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete. In the accompanying drawings, the dimensions and relative dimensions of structures and regions are exaggerated for clarity.

[0035] like Figures 1 to 7 As shown, the oil metering tank provided by this utility model includes a base frame 1; an annular lifting platform 2 is horizontally arranged at the top of the base frame 1 and is fixedly connected to the base frame 1; a calibration tank 3 is arranged on the lifting platform 2 and is spirally connected to the lifting platform 2; an oil calibration inlet 4 is arranged at the top of the calibration tank 3 and is fixedly connected to the calibration tank 3; an annular inlet cover 5 is arranged above the oil calibration inlet 4 and is connected to the oil calibration inlet 4 through a rotating shaft; an annular vibration device 6 is arranged directly below the calibration tank 3 and is connected to the lifting platform 2; a cylindrical negative pressure device 7 is arranged on the inlet cover 5 and is spirally connected to the inlet cover 5; a controller 8 is arranged on the outer wall of the calibration tank 3 and is electrically connected to the vibration device 6 and the negative pressure device 7, and is used to control the start and stop of the vibration device 6 and the negative pressure device 7.

[0036] In use, the vibrating device 6 is aligned with the center of the lifting platform 2. The bottom of the calibration barrel 3 passes through the vibrating device 6 and is spirally connected to the lifting platform 2. This spiral connection effectively fixes the vibrating device 6 between the lifting platform 2 and the calibration barrel 3, ensuring the calibration barrel 3 remains stable and secure during vibration. The negative pressure device 7 is spirally connected to the inlet cover 5 for better sealing and a more secure connection. After installation, the base frame 1 is placed horizontally, and then the fuel nozzle is manually used to add fuel through the fuel testing inlet 4. When testing the volume, stop adding oil, open the controller 8 located on the outer wall of the testing tank 3, and start the vibration device 6 and negative pressure device 7. The vibration device 6 starts vibrating and transmits the vibration to the oil, causing the foam suspended in the oil to break up and float to the surface. After the negative pressure device 7 is activated, it provides a negative pressure environment for the oil metering tank 3, causing the foam to rise and break up more quickly, effectively removing foam. After defoaming, operate the controller 8 to turn off the vibration device 6 and negative pressure device 7. The calibration personnel read and record the oil data, reducing the calibration error caused by foam suspended in the oil and improving the accuracy of the calibration results. This solves the problem that when using a traditional testing tank 3, the extracted oil collides with the inner wall and generates many small bubbles that float in the oil, affecting the calibration results.

[0037] The oil metering tank also includes a level gauge 9, which is vertically installed between the oil testing inlet 4 and the testing tank 3, and is connected to both. The level gauge 9 is a glass level gauge. Through the level gauge 9, the testing personnel can clearly see the foam elimination status inside the oil metering tank, facilitating measurement readings. The oil metering tank also includes a sealing gasket 10, which is installed on the top surface of the oil testing inlet 4 and is fixedly connected to the oil testing inlet 4. The sealing gasket 10 is made of nitrile rubber. This provides a better seal between the oil testing inlet 4 and the inlet cover 5. Nitrile rubber is oil-resistant and provides better sealing. The vibration device 6 is an LRA motor vibration device 6. The LRA motor vibration device 6 is a linear resonant actuator, which has a fast vibration response speed and better vibration effect. The negative pressure device 7 is a small negative pressure pump, which can better provide a negative pressure environment for the oil metering tank and accelerate foam breakage.

[0038] This utility model provides an oil metering container that overcomes the problem that when using traditional oil metering containers for testing, the extracted oil, upon being added to the testing container 3, will collide with the inner wall, generating numerous tiny bubbles that remain suspended in the oil and affect the testing results. The solution involves installing a vibration device 6 on the bottom outer wall of the testing container 3 to accelerate the breaking up of the suspended foam and allow it to float to the surface of the oil. A negative pressure device 7 is installed on the inlet cover 5 to further accelerate the breaking up of the foam that floats to the surface. This effectively removes foam, reduces its impact on the metering results, and ensures high accuracy in the testing.
