Q1: What is a viscometer?
A1: A viscometer is an instrument used to measure the viscosity of fluids (liquids and gases). Viscosity is a physical quantity that indicates the internal friction within the fluid when the fluid is flowing. It is the ability of the fluid to resist deformation. It is an important indicator used to identify some finished or semi-finished products. Viscosity varies from fluid to fluid and varies with temperature. There are mainly three types of capillary viscometers, rotational viscometers and falling ball viscometers.
Q2: What is the definition of viscosity?
A2: When a liquid is flowing, the property of internal friction between its molecules is called the viscosity of the liquid. The viscosity of the liquid is expressed by viscosity, which is a resistance factor used to characterize the properties of the liquid. The viscosity of insulating oil is the same as the viscosity of general liquid, that is, the internal friction of the liquid, that is, when the insulating oil moves relative to laminar flow under the action of external force. The properties of insulating oil molecules that generate internal frictional resistance. The greater the internal friction of the insulating oil, the greater the viscosity, the more difficult the flow, and the poorer heat dissipation performance.
Q3: What is a viscometer used for?
A3: Viscosity is an important physical parameter used to measure the ability of liquids to resist flow. Using a viscometer to measure the viscosity of a liquid is an important means of industrial process control, improving product quality, and saving and developing energy. It is closely related to the fields of petroleum, chemical, electric power, metallurgy and national defense. Status plays an important role.
Tips: The importance of viscometers
In practical engineering and industrial production, it is often necessary to detect the viscosity of the fluid online to ensure the best process operating environment and product quality, thereby improving production efficiency. Through the online measurement of the liquid viscosity in the process, the data of the liquid rheological behavior can be obtained, which has important guiding value for predicting the process control of the product process, the transportability and the operability of the product during use. The characteristics of liquids are often related to other characteristics of the product such as color, density, stability, solid content and molecular weight changes, and the most convenient and sensitive method to detect these characteristics is to detect the viscosity of the liquid online. On-line viscosity testing within the range of process technical requirements can minimize product scrap rate and production line downtime.
