Description

Technical Field

[0001] The utility model relates to the technical field of lubricating oil detection, in particular to a kinematic viscosity tester for lubricating oil production detection. Background Art

[0002] The consumption of petroleum lubricants accounts for more than 97% of the total consumption, so lubricants often refer to petroleum lubricants, which are mainly used to reduce the friction between the surfaces of moving parts. At the same time, they have cooling, sealing, corrosion protection, rust prevention, insulation, power transmission, and impurity cleaning functions for machinery and equipment. They are mainly based on lubricating oil fractions and residual oil fractions from crude oil distillation units. The most important properties of lubricating oil are viscosity, oxidation stability and lubricity, which are closely related to the composition of the lubricating oil fractions.

[0003] In the prior art, a Chinese patent number CN202220138595.7 is disclosed, which is a kinematic viscosity tester for lubricating oil production testing, including a testing platform, a groove is provided on the top of the testing platform, a bracket is installed on the outer wall of the testing platform, an electric telescopic rod is provided on the top wall of the bracket, the telescopic end of the electric telescopic rod is connected to a tensile gauge, and the detection end of the tensile gauge is connected to a pressure plate adapted to the groove, a control mechanism is provided on the testing platform, and a cleaning mechanism is installed on the rear side of the testing platform. The micro water pump is started through the control panel, and the clean water entering the water tank from the water inlet pipe passes through the water supply corrugated hose and is sprayed out by the nozzle, thereby being convenient for use in the next detection and ensuring the accuracy of the next detection result.

This detection method has low detection efficiency and cannot improve the detection efficiency. The degree of automation is low and there is room for improvement. In view of this, a kinematic viscosity meter for lubricating oil production detection is proposed to solve the above problems. Utility Model Content
