一、Overview

The electric six-speed rotary viscometer has been changed from traditional mechanical transmission to single-chip microcomputer control and digital button speed regulation, and the data is more stable in long-term use. According to the multi-point measurement value, the rheological curve is drawn to determine the flow pattern of the liquid in the flow process. An appropriate calculation formula is selected to measure the non-Newtonian fluid more accurately. It can be used for the research and analysis of rheological parameters of the drilling fluid in the field. At the same time, a series of technical parameters such as dynamic, static shear force, flow index and consistency coefficient can be determined. It is conducive to the need for safe, fast and scientific drilling. This product adopts high-quality stepper motor and synchronous belt. Button speed regulation has the characteristics of convenient operation, beautiful and generous, low failure rate and convenient maintenance.
