Instruments for the control of static and dynamic coefficient of friction pair 'METAL filter cake'

摘要

The invention relates to devices for determining the values ​​of the frictional forces of the filter cake of drilling fluids and may find application in the oil industry as well as in laboratory research in the disciplines "of drilling and cement slurries" and "Complications and accident in drilling" in universities CIS Profile. The task to be solved by the proposed utility model, is to increase the accuracy of measurement by the known patterns of resistance values ​​of the recording powers that arise between the metal load and the filter cake during movement and rest directly on a computer. The technical effect is to provide control of static and dynamic coefficient of friction at a constant contact area at system "metal filter cake." The objective is achieved in that the device for controlling the static and dynamic friction coefficient couples "metal-filter cake" containing base table mounted thereon an electric motor, the level of the traction measuring unit connected, on the one hand, by means of thread a pulley electric motor, on the other - by a spring with a load, a base for placement of load, according to the proposed utility model for the base load and load placement have a flat working surface, while in traction metering unit efforts mounted strain gauge sensor for detecting mechanical forces change.
