Grease is a kind of lubricating material between liquid and solid. In a certain sense, it has the advantages of both. At room temperature and static state, the grease is a plastic body that can adhere to the friction surface and does not flow like a solid. Under the action of heat and mechanical action, the lubricating grease becomes thinner and can lubricate the friction surface like liquid under the condition of increasing temperature and motion. When the thermal and mechanical effects gradually become smaller and even disappear, the grease gradually becomes thicker and even restores to a certain viscosity, However, it is likely not to restore the original viscosity. Because of this particularity, grease plays an increasingly important role in industry, agriculture, transportation, defense industry and other departments.

The temperature is high in summer, and improper oil selection can easily cause low oil pressure, which can damage the engine in severe cases. Therefore, in summer, vehicles must pay attention to the correct selection and use of lubricating oil. How to choose lubricating oil in summer Suggeations: So in summer, special attention should be…
( 1 ) The amount of grease should be appropriate Too much grease will increase the friction torque, temperature and fat consumption. If the amount of fatliquoring is too small, the reliable lubrication cannot be obtained and dry friction occurs. Generally speaking, the appropriate amount of grease is 1 / 3 ~ 1 / 2…
