1. , a kind of fluid viscosity measuring method of capillary pipeline is characterized in that:

  • use the fluid viscosity measurement mechanism of an application of sample capillary pipeline to carry out data acquisition, utilization is resolved processor data is handled, the viscosity data of output detected fluid;

    A, in the tested liquid sample cup, inject tested liquid, in tested liquid sample cup, put into test solution, described fluid viscosity measurement mechanism is in 20 ℃



    40 ℃

    the environment, make the fluid temperature in all sample cups reach uniformity;

    B, the described fluid viscosity measurement mechanism of startup, sample needle is extend in the tested liquid in the tested liquid sample cup, use sample needle to draw tested liquid according to predefined constant rate parameter, collect the pressure parameter P1 of described tested liquid by the pressure transducer on the application of sample capillary pipeline, and this pressure parameter is sent to resolves processor;

    C, control sample-adding pump carry out the stock layout operation, with the tested liquid emptying of drawing;

    D, control sample-adding pump are inhaled the sample operation once more, sample needle is extend in the test solution in the tested liquid sample cup, use sample needle to draw test solution according to the flow parameter identical with drawing tested liquid, collect the pressure parameter P of test solution by described pressure transducer, and this pressure parameter is sent to resolves processor;

    E, use and to resolve processor, draw the test solution viscosity data according to calculating formula V=Vgd * (P-P0)/(P1-P0) calculate.
