The purpose of oil determination is to ensure the quality, performance and applicability of oil to meet the needs of industry, automobiles, aviation and other fields. Determination helps to ensure smooth operation of equipment, extend mechanical life, improve efficiency, and prevent environmental po

I. Aviation lubricant oil contamination detection methodThe contamination of aviation lubricants can be detected and evaluated by a variety of methods, some of which are common methods:1. Particle counting methodUse a particle counter to detect the number and size of solid particles in the lubricant

The heat resistance temperature of high-temperature lubricating oil varies depending on its type and brand, usually between 200°C and 300°C. This oil is often used in high-temperature industrial environments, such as steel manufacturing, metal processing, automobile manufacturing and oil refining.

Ⅰ. What is the purpose of oil flash point determination?Answer: Determine the flammability and safety of oil products.Analysis: Flash point refers to the lowest temperature at which the vapor released by a liquid under a specific pressure can instantly ignite when it comes into contact with an igni

I. The difference between kinematic viscosity and dynamic viscosityKinematic viscosity (kinematic viscosity) and dynamic viscosity (dynamic viscosity) are two descriptions of liquid viscosity or flow properties of different physical properties, the difference is as follows:1, the differe

Equipment lubrication is figuratively likened to the "life blood" of the mechanical world, which is not an exaggeration. In various fields such as industrial production, transportation, construction engineering, lubrication is an indispensable link to ensure the normal operation of mechanical equipment. Whether it is a huge factory production line or small mechanical equipment, proper lubrication is needed to reduce friction, cool components, seal critical parts, and prevent corrosion. However, to truly understand the importance of lubrication requires an in-depth understanding of its profound impact on equipment performance and life.

Compressor lubrication refers to reducing friction and wear by adding appropriate lubricants during the operation of the compressor to ensure the smooth operation and long-term reliability of the mechanical components. It is mainly to reduce energy consumption, improve work efficiency, extend equipm

The lower half of the split sleeve bearing has obvious wear and performance failure phenomenon, which leads to the abnormal running state of the cold water pump. The color of the oil sample found in the split sleeve bearing shows an anomaly, appearing green or gray, which is significantly different
