1.The concept of cone penetration Grease cone penetration is the depth of grease pressed into a conical container under certain conditions. It is usually used to evaluate the hardness and viscosity of grease. The measurement of grease cone penetration can help engineers choose the appropriate type of grease to ensure the normal operation of machinery…

The problem of grease drying and hardening caused by oil separation, if this process occurs during the operation of machine components, such as bearings and gears, will have adverse consequences for their normal operation. As the grease drys and hardens, the friction intensifies, causing the bearing temperature to rise, and the rising temperature in turn…

To make the vehicle work normally, the lubricity of the vehicle chassis is also very important. Poor lubrication will also cause damage to the parts, there is the possibility of failure. It also has a great influence on the technical condition of the vehicle.If the situation is serious, it will also pose a hidden danger…

There are three main functions of the valve sealing grease: What is valve sealing grease ? Valve sealing grease : mainly for the valve to provide sealing, such products are mostly used for plug、 ball and gate valve, due to its rheological properties,so that the grease can penetrate and fill the fine space generated on…

Valve grease is a kind of rubber and plastic lubricant.Even in occasions with great changes in temperature and humidity,we can use it for long-term lubrication. It will not carbonize or evaporate at high temperature, and will not melt or harden when exposed to high temperature. Insoluble in water, methanol, ethanol, ethylene glycol and resistant to…

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.What is the base oils Almost all the lubricants in use are formulated from base oil. The formulation of lubricants begins with base oil, and a small amount of additives are added to the base oil to form lubricants. Lubricating grease is also based on base oil, adding thickeners and a small amount of additives…

1.Determine the brand of lithium grease : When choosing lithium grease，we should determine the brand of lithium grease.The grade of grease is divided according to consistency ( NLGI consistency grade ), and lithium grease is also divided into different consistency. The larger the consistency grade is, the harder the lithium grease is, the smaller the…
