AI Technical Summary

Technical Problem

After use, existing lubricating oil flash point testers leave a large amount of lubricating oil stains on the inner wall of the test cylinder, affecting the cleanliness of the test cylinder and the accuracy of subsequent tests.

Method used

A flash point tester for lubricating oil was designed. The tester uses a wiping sponge to contact the inner wall of the test cylinder and a rotating cleaning mechanism consisting of an electric heating rod and a scraper. Combined with the use of an oil cleaning solution, the inner wall of the test cylinder is cleaned. At the same time, the electric heating rod is used to stir and heat the lubricating oil.

Benefits of technology

It effectively cleans the lubricating oil stains on the inner wall of the test cylinder, ensuring the cleanliness of the test cylinder and ensuring accuracy in the next use. Stirring and heating also improve the uniformity of the lubricating oil and the efficiency of the test.

Abstract

The utility model relates to the technical field of lubricating oil test equipment, and particularly discloses a lubricating oil flash point tester which comprises a test cylinder, a mounting shaft is rotatably mounted in the test cylinder, a plurality of electric heating rods are mounted on the outer wall of the mounting shaft, scrapers are mounted at the ends of the electric heating rods, and wiping sponge is mounted on one side, far away from the mounting shaft, of each scraper. The wiping sponge is in contact with the inner wall of the test cylinder. According to the utility model, the wiping sponge is in contact with the inner wall of the test cylinder, and the wiping sponge rotates to generate friction with the inner wall of the test cylinder, so that the wiping sponge can be used for cleaning residual lubricating oil on the inner wall of the test cylinder while being used for smearing oil stain cleaning liquid on the inner wall of the test cylinder; and therefore, residual lubricating oil on the inner wall of the test cylinder can be conveniently cleaned, the cleanliness of the inner wall of the test cylinder is ensured, and the test cylinder is ensured to be in a clean state when being used next time.
