Abstract
A pressurizing rotary rheometer used in viscosity measurement of high-concentration viscous homogeneous fluid can aims at the rheological measurement of high-concentration viscous slurry containing big particles under pressurizing state. The instrument comprises servo-motor driving system, viscosity measuring system, hydraulic drive system and so on. In the viscosity measuring system, the hydraulic cylinder part, viscosity measuring part, torque sensor and AC servo-motor are coaxially installed on a vertical type bracket orderly.
Description
Affiliated technical field
The present invention relates to a kind of instrument of measuring rheological characteristics under high viscosity " thickness homogeneous fluid " condition of high voltage that can be used in.
Background technology
At present, known rotational viscosimeter and flow graph are mostly ignored the influence of pressure to viscosity, can only carry out the viscosimetric analysis under the normal pressure.The minority pressurizing rotary rheometer is because reasons in structure also can only be carried out petroleum drilling fluid and all kinds of oil body mensuration under the pressurized conditions, for being applicable to that fully the pressure measuring device that adds of measuring higher " thickness homogeneous fluid " viscosity of concentration does not also have.
Summary of the invention
Can not realize measuring under the pressurized conditions deficiency of higher " thickness homogeneous fluid " rheological characteristics of concentration in order to overcome existing rotational viscosimeter, the invention provides a kind of pressurizing rotary rheometer, this pressurizing rotary rheometer can not only be measured the rheological characteristics of " thickness homogeneous fluid " under the normal pressure, and can measure the variation tendency of fluid rheological characteristics under the different pressures easily.
The technical solution adopted for the present invention to solve the technical problems is: the inside and outside cylinder of its viscosity measurement system is coaxially installed in the pressure resistant vessel, and the tested sample that directly acts in the container by piston produces high pressure.Before the measurement, be full of tested sample in pressure resistant vessel, provide power by fluid power system, the piston that promotes on the hydraulic pressure cylinder assembly moves reciprocatingly in pressure resistant vessel, directly to tested sample pressurization or unloading, produces and keeps a steady testing pressure environment.In the pressure resistant vessel bottom pressure transducer is housed and measures this force value.In the measuring process, driving the rotor that is packaged in the pressure resistant vessel by AC servo motor rotates under constant rotating speed, tested sample is sheared, and measures the suffered viscosity moment in relevant shear speed lower rotor part surface by the torque sensor that is installed on the motor output shaft.Under the identical situation of conditions such as rotational speed, this torque will change with the viscosity of fluid, and the big more torque of viscosity is big more, therefore measures the viscosity that torque just can be known fluid.
The invention has the beneficial effects as follows, can test " thickness homogeneous fluid " rheological characteristics under pressurized state.
