Abstract

The invention relates to the field of viscometers and discloses a diluted Ubbelohde viscometer. The viscometer comprises a liquid suction / discharge pipe (3) and a measuring tube (2). One side of the measuring tube (2) is connected to an escape pipe (1). The lower end of the measuring tube (2) is connected to a liquid feeding / discharge pipe (7). A mixing ball (6) is connected to the lower part of the liquid suction / discharge pipe (3). The liquid feeding / discharge pipe (7) is inserted into the bottom of the mixing ball (6). The lower end of the mixing ball (6) is connected to a raw liquid inletpipe (61). The opening of the liquid suction / discharge pipe (3) is connected to a liquid suction device (30) and a liquid pushing device (31). The measuring tube (2), the escape pipe (1), the liquid suction / discharge pipe (3) and the raw liquid inlet pipe (61) are connected to switches for controlling pipe opening sealing. The diluted Ubbelohde viscometer realizes convenient sample feeding, has uniform stirring effects, produces accurate measurement results, is cleaned through simple processes and has a high recovery rate of the sample solution and the cleaning solution.

Description

technical field [0001] The invention relates to the field of viscometers, in particular to a diluted Ubbelohde viscometer. Background technique [0002] The Ubbelohde viscometer is mainly used to measure the kinematic viscosity of the liquid. It is a gravity-type capillary viscometer. Compared with the viscometer, the liquid storage ball of the sample is designed at the bottom, and the bottom is designed to be flat, and the automatic sampling tube is added to realize the fully automatic sampling, stirring, measurement, cleaning, etc. of the diluted viscometer. Monopoly. Traditional diluters are not fully automated at present in China. Traditional sample addition, stirring and measurement are all done manually, and the measured data has large errors, takes a long time, and consumes a lot of chemical solvents for cleaning, polluting the environment. Contents of the invention [0003] The present invention aims at the shortcomings of the prior art, such as inconvenient clea...
