A test device and test method for strong oxidation of lubricating oil

Abstract

The invention provides a strong lubricant oil oxidation test device and a test method, and belongs to the technical field of engineering machines. The strong lubricant oil oxidation test device comprises a first oxidation bin 1 and a heater 2 used for heating the first oxidation bin 1, wherein the first oxidation bin 1 is arranged in the heater 2, the first oxidation bin 1 comprises a sealing chamber 11 containing lubricating oil and a sampling tube 12, the sampling tube 12 is arranged on the sealing chamber 11, one end of the sampling tube 12 is arranged in the sealing chamber 11, and the other end of the sampling tube is positioned outside the sealing chamber 11. The test method comprises the steps of heating the first oxidation bin 1 by the heater 2, and taking the sampling tube 12 out to be measured. The strong lubricant oil oxidation test device is provided with the oxidation bin capable of adjusting test conditions, so that a plurality of lubricant oil samples can be simultaneously tested, the test time can be added or reduced, and multiple properties of lubricant oil can be tested.

Description

technical field [0001] The invention belongs to the technical field of engineering lubricating oil, and relates to an oxidation test device and a test method, in particular to a lubricating oil strong oxidation test device and a test method. Background technique [0002] Oxidation of lubricating oil is one of the most important reasons for oil deterioration. During the oxidation process, compounds such as peroxides, alcohols, aldehydes, acids, esters, and hydroxy acids are produced. The acidic substances in them will corrode the metal, and the metal ions produced by corrosion are catalysts for oil oxidation, accelerating the oxidation of oil. . These compounds can also be further condensed to form oil-insoluble substances, forming paint films, carbon deposits and sludge, resulting in blockage of oil passages. In addition, various organic acid products will also cause corrosion of metals (piston rings and cylinder liners, bearings, etc.), thereby increasing wear and tear. ...

AI Technical Summary

Problems solved by technology

[0006]Before the present invention, the inventor found that the prior art had at least the following problems: the test results of the rotating oxygen bomb and other test methods were the induced oxidation time of lubricating oil, which did not represent the actual Oxidation time, and the test results have large errors and poor repeatability;

[0008]Most of the other methods have the problem that the amount of oxidized oil sample is small and it is difficult to test various items, or there are problems such as the inability to test multiple oil samples at the same time
