Viscometer

Abstract

The invention relates to a viscometer which comprises a testing device and a heating device, wherein the test device comprises a measuring head, a rotor, a cover and a platinum wire; the measuring head and one part of the platinum wire are contained in the cover; the rotor is hung below the measuring head by virtue of the platinum wire; the heating device comprises a hearth, a crucible and a mobile platform; a to-be-tested fused salt is arranged in the crucible; the rotor is immersed in the fused salt and is coaxial with the center of the crucible; the crucible is arranged in the hearth; the top end of the hearth is connected with the cover in a sealed mode; and the bottom end of the hearth is connected with the mobile platform in a sealed mode. According to the viscometer disclosed by the invention, the measuring head and the rotor are connected by virtue of the platinum wire, so that the size of a gap between the rotor and the crucible can be 0.5-2mm, and the viscosity test range of 1-50cP is met. Meanwhile, the operation of the measuring device is not influenced by the temperature of the heating device by virtue of the length of the platinum wire, so that the requirement of measuring the viscosity of high-temperature low-viscosity fused salts at the temperature of 100-1000 DEG C is met.

Description

Technical field [0001] The invention relates to a measuring device, and more particularly to a viscometer. Background technique [0002] In order to measure the viscosity of the fluid, people usually use the principle of the rotation method to determine the viscosity of the fluid by measuring the viscous torque of the fluid acting on the rotor or the rotation speed of the rotor. The existing viscometer mainly includes a testing device and a heating device, the testing device is connected to a rotor, and the heating device is provided with a crucible, and the fluid is carried in the crucible. When either or both of the fluid and the rotor immersed in it rotate, the rotor will be affected by the viscous torque of the fluid to change the original speed and torque, so that the viscosity of the fluid can be directly measured by the viscometer. [0003] Existing viscometers can generally be divided into two types, one is a viscometer that meets the lower limit of low viscosity detection...
