Abstract

The invention relates to a viscometer, comprising: a testing device, which includes a measuring head, a rotor, a cover body and a platinum wire, the measuring head and part of the platinum wire are housed in the cover, and the rotor is suspended below the measuring head through the platinum wire; The heating device includes a furnace, a crucible and a mobile platform. The molten salt to be tested is carried in the crucible, the rotor is immersed in the molten salt and coaxially arranged with the center of the crucible, the crucible is set in the furnace, and the top of the furnace is sealed with the cover. , the bottom end of the furnace is sealed and connected with the mobile platform. The viscometer of the present invention connects the measuring head and the rotor through a platinum wire, so that the size of the gap between the rotor and the crucible can be only 0.5-2mm, thereby meeting the viscosity test range of 1-50cP. At the same time, the invention uses the length of the platinum wire so that the temperature of the heating device will not affect the operation of the measuring device, thereby meeting the requirement of measuring the viscosity of high-temperature and low-viscosity molten salt between 100-1000°C.

Description

technical field [0001] The invention relates to a measuring device, 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 moment of the fluid acting on the rotor or the rotational 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 a crucible is arranged in the heating device, and a fluid is carried in the crucible. When one or both of the fluid and the rotor immersed in it rotates, 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 categories, one is viscometers designed to meet the detection lower limit require...
