Technical Field

[0001] The utility model relates to the technical field of lubrication detection, in particular to aviation lubricating oil viscosity measuring equipment. Background Art

[0002] Equipment such as aircraft engines need to operate under high temperature and high pressure. The viscosity of lubricating oil directly affects its lubrication performance under high temperature conditions. The correct viscosity can ensure that the lubricating oil can effectively lubricate under various working conditions, reduce wear and friction, and extend the service life of the equipment. Therefore, it is necessary to measure the viscosity of the lubricating oil. The existing lubricating oil kinematic viscosity tester is usually used to measure the kinematic viscosity of the lubricating oil. The tester uses a glass capillary viscometer and a constant temperature box for measurement.

[0003] When measuring the kinematic viscosity of lubricating oil, it is necessary to ensure that the capillary is placed vertically in the constant temperature bathtub. This operation is difficult because once it is tilted, it is likely to cause deviations in the test results. Retesting will increase the burden on the measuring staff. In addition, when the constant temperature bathtub is heated, the bath liquid is often heated unevenly, and the heating efficiency is low, which affects the test results. Utility Model Content
