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. Lubricating oil dynamic viscosity detection methodThe viscosity of lubricating oil refers to its fluidity and viscosity, which is crucial to the performance and lubrication effect of mechanical equipment. There are several common methods for testing the dynamic viscosity of lubricating oil, some

Ⅰ. What is the standard of water content in lubricating oil?Answer: Ordinary lubricating oil: about 0.2%, high temperature lubricating oil: about 0.1%, automotive lubricating oil: about 0.05%, industrial gear oil: about 0.05%, hydraulic oil: about 0.1%.The water content standard of lubricating oil

Ⅰ. What are the aspects of lubricant quality testing?Lubricant quality testing involves many aspects, mainly including the following aspects:1. Viscosity: The viscosity of lubricating oil refers to its fluidity and viscosity, which is usually tested at different temperatures to ensure that it can p

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

What is the flash point? The flash point refers to the lowest temperature at which a liquid begins to release enough vapor under certain conditions to produce a combustible gas mixture and ignite when it comes into contact with a heat source in the air. For lubricating oil, the flash point refers to

Ⅰ. What chemical method does the flash point test of lubricating oil belong to?Answer: The flash point test of lubricating oil is usually a physical test method.The flash point is used to determine the temperature at which lubricating oil or other liquids begin to flash under specific conditions. T

I. What are the causes of low lubricating oil pressure in marine gearboxes?Answer: The causes include insufficient oil flow, problems with the lubricating oil pump, excessively high oil viscosity, oil leakage, filter blockage, oil contamination, internal system failures, low liquid level, hydraulic

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
