Abstract

The invention relates to the field of viscometers, and discloses a ubbelohde viscometer. The ubbelohde viscometer comprises a liquid draining pipe (3) and a measurement pipe (2), wherein a lower liquid storage ball (6) is connected with the lower part of the liquid draining pipe (3); the lower part of the lower liquid storage ball (6) is communicated with a liquid inlet and outlet pipe (7) which is directly inserted into a sample bottle; the bottom of the measurement pipe (2) is communicated with the bottom of the lower liquid storage ball (6); one side of the measurement pipe (2) is connectedwith a blow-down pipe (1); the measurement pipe (2) is sequentially connected with an upper liquid storage ball (12), a timing ball (11), a capillary pipe (10) and a suspending liquid column ball (8)from top to bottom; and the suspending liquid column ball (8) is communicated with the liquid inlet and outlet pipe (7) and the lower liquid storage ball (6). The viscometer has the advantages of accurate measurement and simple liquid reclaiming and the like, is easy for automatic control, and is convenient to wash.

Description

technical field [0001] The invention relates to the field of viscometers, in particular to an Ubbelohde viscometer. Background technique [0002] Ubbelohde viscometer (see attached figure 2 : traditional Ubbelohde viscometer) is mainly used to measure the kinematic viscosity of the liquid. It is a gravity-type capillary viscometer. Compared with other U-shaped gravity viscometers, it has an additional vent tube and a suspended liquid column ball, which forms a suspended liquid column during measurement, so it is not affected by the amount of liquid added and the liquid level in the liquid storage ball. The test accuracy Higher than other gravity viscometers (manual measurement can reach 0.1%) and widely used. However, the three nozzles of the traditional Ubbelohde viscometer are all upward, and the sample needs to be added from the upper part, and the liquid is discharged from the upper part. When the waste liquid is discharged, it will pollute the entire area of ​​the th...
