一、多系数粘度計測定运动粘度用的品开維奇粘度計,每支只有一个系数,要想广泛的測定各种大小粘度試油,化驗室就需要配备各种不同內徑的粘度計,以供选用。为了一物多用,简化設备和减少測定粘度計系数的煩瑣工作,我們設計了一种多系数粘度計,一支可代替品开維奇一組(六支)粘度計使用。多系数粘度計与品开維奇粘度計基本相似,只是将粘度計的A端由两个球改为三个球,而且球的体积不同,从上到下遂个增大,每个球的頸部窄处都有一条
First, the multi-coefficient viscometer used to determine the kinematic viscosity Goods open Vichy Viscometer, each only one coefficient, in order to determine a wide range of viscosity test oil, the laboratory needs to be equipped with a variety of different diameter viscometer, For selection. For a multi-purpose, simplified equipment and cumbersome determination of the viscometer coefficient, we designed a multi-coefficient viscometer, a substitute for the open-Vechi group (six) viscometer use. The multi-coefficient viscometer is basically similar to Viktori Viscometer, except that the A-end of the viscometer is changed from two balls to three balls, and the volume of the ball is different, increasing from top to bottom. Each ball There is a narrow neck
