Flushing apparatus for a drilling mud testing system

Patent ·
OSTI ID:5983199
A system for testing the parameters of drilling mud has a flush pump for periodically flushing drilling mud from the components of the system. The flush pump includes a piston driven by a source of pressurized air selectively applied to one side to pressurize flush water and to the other side to retract the piston and to draw another volume of flush water from the source. A solenoid valve between the flush pump and viscosity measuring tubes in the system connects the volume of pressurized flush water in the pump to a tap of the measuring tubes by displacement of the piston.
