China Kinematic Viscosity Manufacturers, Suppliers, Factory

Here at Weshine®, we invented Kinematic Viscosity Tester for make sure the transformer oil is in the perfect situlation. Kinematic Viscosity Test Instrument is designed as per ASTM D 445 to determine kinematic viscosity of liquid petroleum products including transparent and opaque liquid, by time measurement for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer. Weshine® can provide both manual and automated type of Kinematic Viscosity Tester for customer choosing.

Kinematic Viscosity play an important role in cooling performance of oil-immersed transformers, cause besides providing the transformer with a liquid dielectric insulating medium, transformer oil also serves as the transformer’s major coolant and heat transfer medium. If the transformer design is fixed, and if it is a transformer with natural oil flow (thermosyphon circulation without pump) and natural air circulation without fans (by IEC terms this is called ONAN Oil Natural Air Natural), then it is mainly the physical properties of the insulating oil that plays the most important role. This can be understood as a low viscosity oil will allow for a higher circulation speed of the oil that results in a better efficiency of the cooling system. Or in words: The lower the viscosity, the higher the circulation speed of the oil which equates in a higher quantity of heat being dissipated.

Automatic Kinematic Viscometer

Automatic Kinematic Viscometer is a special test instrument designed and manufactured according to the national standard "GB/T265-88 Determination of Kinematic Viscosity of Petroleum Products", which is suitable for measuring the kinematic viscosity of liquid petroleum products. The instrument has timing sample movement time and automatically calculates the final result of kinematic viscosity. This method is suitable for the determination of the kinematic viscosity of liquid petroleum products (referring to Newtonian liquids). The product of the constant and the flow time is the kinematic viscosity of the liquid at this temperature.
