Description

Technical Field

[0001] The utility model belongs to the technical field of lubricating oil sampling, and particularly relates to a lubricating oil quantitative extraction device. Background Art

[0002] Lubricating oil is a technology-intensive product and a complex mixture of hydrocarbons. Its actual performance is the combined effect of complex physical or chemical changes. Lubricating oil is stored in storage tanks and an extraction device is required to extract the oil.

[0003] For example, a Chinese patent with publication number CN217424844U discloses a lubricating oil sampling device, including a tank body, a drive box, a collection pipe and a negative pressure device. A feed pipe is provided inside the tank body, and the feed pipe passes through the tank body and is connected to the drive box. The drive box is located outside the tank body, and the interior of the drive box is fixedly connected to the collection pipe. The bottom of the feed pipe is connected to the negative pressure device through a discharge pipe.

[0004] Although the above-mentioned sampling device is convenient for taking lubricating oil samples, the existing sampling device still has some shortcomings that need to be improved. Lubricating oil usually has a certain viscosity. The lubricating oil is left stationary in the storage tank. If there is no external interference, it will gradually stabilize and form a relatively static state. Lubricating oil with higher viscosity has poor fluidity, so a larger external force is required to make it flow. The extraction process will be very difficult, and it is also difficult to extract the stationary lubricating oil by pulling the drive block to drive the piston plate, and the oil extraction efficiency is slow.
