The six speed rotational viscometer is manufactured according to the specifications of the American Petroleum Institute (API), and can measure various rheological parameters. At the same time, a series of technical parameters such as action, static shear force, flowability index, and viscosity coefficient can be measured.
The principle of operation of the machine is powered by an electric motor, and during measurement, the drilling fluid sample is injected into the annular space between the float and the outer casing. By driving the rotor with a motor, the outer sleeve is connected to rotate at a certain speed. The rotation of the outer sleeve in the sample will apply a certain torque to the float, which is reflected on the dial through the reaction force of the torsion spring. Calculate the final viscosity value through the formula.
1. The float shaft bearing adopts a high-precision zirconia all ceramic bearing to improve product accuracy and service life,
2. The shell is made of cast aluminum alloy and car paint technology, which is lightweight, beautiful, and durable
3. Equipped with a dedicated portable injection molding packaging box and an aluminum alloy shell, it has a small self weight,
