Abstract

The invention provides a constant-temperature device for measuring liquid viscosity. The constant-temperature device for testing liquid viscosity can effectively control a temperature of a sample needing to be tested in liquid viscosity measurement, and guarantee the accuracy of measured data. The constant-temperature device for testing liquid viscosity comprises a sample measuring cup and a constant-temperature water bath. The constant-temperature water bath comprises a bath tank and a circulating pump which is connected to the bath tank through a pipe and is utilized for driving a liquid in the bath tank to flow circularly. The bath tank of the constant-temperature water bath is provided with a water inlet and a water outlet. The sample measuring cup comprises an inner cylinder and an outer cylinder, wherein the outer cylinder is coaxially sleeved on the inner cylinder. The inner cylinder is utilized for loading a liquid sample. The outer cylinder is provided with a water outlet pipe and a water inlet pipe. The water inlet pipe is connected to the water outlet of the constant-temperature water bath. The water outlet pipe is connected to the water inlet of the constant-temperature water bath. An interlayer space between the inner cylinder and the outer cylinder forms a constant temperature layer. The constant temperature layer is communicated with the bath tank of the constant-temperature water bath by the water outlet pipe and the water inlet pipe.

Description

technical field [0001] The invention relates to the technical field of liquid viscosity testing, in particular to a constant temperature device for testing liquid viscosity. Background technique [0002] When the liquid is flowing, the property of internal friction between its molecules is called the viscosity of the liquid. The viscosity is expressed by viscosity, which is used to characterize the resistance factor related to the properties of the liquid. Viscosity is divided into dynamic viscosity, kinematic viscosity and conditional viscosity. Viscosity is a property of a fluid. Different fluids have different viscosity values. The viscosity of the same fluid is significantly related to temperature. The viscosity of a liquid will decrease as the temperature increases. [0003] The viscosity data of various liquids are mainly measured by experiments. The commonly used viscometers currently used to test the viscosity of liquids are Brookfield viscometers or rotary viscome...
