Six-speed rotational viscometer FANN-35

Six-speed rotational viscometer Model: FANN-35 instrument Information: Fann viscometer directly read has 60 years of manufacturing history, F26-Fann35 viscometer drilling fluid viscosity is considered standard industry test tools. Information is as follows: Recommended for assessment Binghamplastics (Bingham plastic) material. The instrument is factory equipped R1RotorSleeve (rotor hub), B1Bob (hammer), F1TorsionSpring (torsion spring) and a stainless steel sample cup, according AP1Recommended Practice, 13B test. With other rotor - a hammer and a torque spring may extend or improve the torque measuring range torque measurement sensitivity. Shear stress can be directly read from the calibrated scale. Yield point and plastic viscosity of the fluid can be determined, the method is simple. When the instrument combination with R1-B1 and standard F1 torque spring, from the observed data for as long as two subtraction can be. Portable instrument case can be step-down transformer and other accessories. F26-Fann35 viscometer is used in research and production of general-purpose equipment, even when using a power source where the frequency adjustment may also be used. 6-speed, using test speed 600,300,200,100,6 and 3rpm (r / min), through synchronous motor drive precision gearing. Without stopping the rotation you can select any speed. Shear stress is continuously displayed on the calibrated scale. Therefore, the time - dependent viscosity characteristics can be observed as a function of time. 35A-type with 60Hz motor, F26-Fann35SA type with 50Hz motor. A total of 12 kinds of speed scalable range of shear rates. 600,300,200,180,100,90,60,30,6,3,1.8 and 0.9rpm speed synchronous motor drive SR12 via a gearbox, then through 35 type viscometer precision gearbox. He added a 10: 3 by a two-position deceleration transmission shaft to choose. SR12 gearbox can be used as the F26-Fann35 type of modification assembly.
