Description

And, lubricating oil is a technology-intensive product, which is a complex mixture of hydrocarbons, and its true performance is the comprehensive effect of complex physical or chemical changes. The basic performance of lubricating oil includes general physical and chemical properties, special physical and chemical properties and simulation bench test.

[0003] At present, when producing and processing lubricating oil, some chemical workers will blend lubricating oil in the studio to detect its performance. At present, the blending of lubricating oil is mostly stirred and blended by mechanical stirrers or magnetic stirrers. The mechanical stirrer is easy to contaminate too much lubricating oil because of the stirring blade and other elements, resulting in high consumption of experimental oil and difficult to clean. Although the magnetic stirrer has less lubricating oil contamination when blending lubricating oil, the magnetic stirrer still needs to be taken out from the beaker by using tweezers or clamps. On the one hand, the tweezers or clamps are easy to contaminate when they are deeply inserted into the blended lubricating oil. On the other hand, the tweezers or clamps are also easy to contaminate a large amount of lubricating oil, which causes lubricating oil consumption. In addition, the lubricating oil on the tweezers or clamps is easy to "draw silk" and contaminate the test bench when the magnetic stirrer is taken out. At the same time, the magnetic stirrer is fixed, which limits the stirring range when using some large diameter beakers for experiments, and causes the hidden danger of poor stirring effect.

[0004] Therefore, it is necessary to provide a new magnetic stirrer with adjustable magnetic rotation radius to solve the above technical problems. UTILITY MODEL CONTENTS
