Abstract

The invention discloses a high-pressure rotational viscosity meter. The high-pressure rotational viscosity meter comprises a shell composed of an upper cylinder and a lower cylinder, a cylindrical rotor is arranged in the shell, a rotating disc is connected to the upper end of the cylindrical rotor, magnetic steel and a hall rotational speed sensor are arranged on the rotating disc, and a magnetic force conduction device is arranged at the lower end of the cylindrical rotor. The high-pressure rotational viscosity meter is suitable for measuring the viscosity of a lubricating agent in the normal-temperature and normal-pressure states, is also capable of changing experiment pressure so that the viscosity of the lubricating agent in the normal pressure state can be measured, the universal performance of the high-pressure rotational viscosity meter is improved, measurement of viscosity of all kinds of fluid in the different-high-pressure and different-shearing-rate states can be achieved through a measurement device, the research and development cost is effectively reduced.

Description

technical field [0001] The invention belongs to the technical field of fluid viscosity measuring equipment, in particular to a high-pressure rotary viscometer. Background technique [0002] Viscosity is a physical characteristic of fluid substances, which reflects the internal friction between molecules when the fluid is subjected to external forces. In industrial production and scientific research, viscosity is the most important quality index of lubricating oil. Choosing lubricating oil with proper viscosity can give full play to the role of lubricating oil and ensure that mechanical equipment is in a stable and reliable working state. At present, there are many types of viscometers, among which rotary viscometers are widely used and have high precision. Rotary viscometers are widely used in the production and scientific research activities of oil, paint, coating, plastic, food, medicine, adhesive and other industries. At present, most of the commonly used rotational visc...
