Abstract

The invention relates to a kinematic viscosity measuring device, which comprises a double-bulb capillary viscometer, a sealed constant-temperature box, a fixing jacket, a positioning platform, an automatic timing system and a suction cleaning system, wherein the sealed constant-temperature box is rotationally assembled on the positioning platform, and the double-bulb capillary viscometer is fixedin the sealed constant-temperature box by means of the fixing jacket; openings in the upper ends of a main pipe and a branch pipe of the double-bulb capillary viscometer are communicated with the suction cleaning system by means of pipelines respectively, liquid level sensors are arranged on the upper and lower sides of an upper bulb and a lower bulb of the double-bulb capillary viscometer respectively, and the liquid level sensors are in data transmission connection with the automatic timing system respectively. Therefore, the problem that a kinematic viscosity measuring device in the prior art cannot realize automatic measurement in a wide viscosity range. The invention further provides a using method of the kinematic viscosity measuring device, and the using method is used for preciselymeasuring the viscosity-temperature properties of non-transparent liquids or liquids of various colors.

Description

technical field [0001] The invention relates to a device for measuring kinematic viscosity and a using method thereof. Background technique [0002] Viscosity measurement is an important means of controlling production process, ensuring production safety, evaluating product quality, medical testing and scientific research in the fields of petroleum, chemical industry, medicine, food, textile and national defense. Capillary viscometer is one of the important methods of kinematic viscosity measurement. It is recognized as the method with the highest accuracy in viscosity measurement and is indispensable in petroleum, chemical, pharmaceutical and other industries. [0003] The capillary viscometer is based on the principle of relative measurement, which is to measure the time required for a certain volume of liquid to flow through a capillary under the action of gravity. Common capillary viscometers are divided into positive flow Ping, Ubbelohde, and Finn capillary viscometers...
