TT100 In-Line Viscometer Installation, Operation, Maintenance and Service Instructions
P/N M/97-520 1-11
Drive Endcap
The Drive Endcap supports the rotor, mechanical seal, drive shaft, bearings
and bearing housing, motor, and all related mechanical components.
Motor Cable
The Motor Cable supplies electrical power to the motor from the motor
control enclosure, or directly from a power source.
Gearbox
The Gearbox reduces rotational speed and allows the drive shaft to rotate
slower than the motor. The rotational speed of the drive shaft is determined
by Brookfield Engineering Laboratories, Inc. based upon customer
viscosity range requirements.
Drive Motor
The Drive Motor is an electric motor which provides a constant rotational
speed to the gear box, drive coupling, and viscometer drive shaft. The
drive motor is usually a single-speed synchronous motor but is also
available in a controlled variable speed induction motor for custom
applications.
Drive Coupling
The Drive Coupling connects the viscometer drive shaft to the
gear box. The drive coupling contains a rubber cushion (or bronze cushion
for high temperature applications) to isolate the viscometer from motor
vibration.
Bleed Screw
The Bleed Screw is used to vent air from the viscometer which may be
trapped within the measuring chamber.
Measuring Chamber
The Measuring Chamber is the area in which process fluid viscosity is
measured. Process fluid may flow through it in either direction.
Measuring Annulus
The Measuring Annulus is the space between the stator and rotor. Process
fluid is continuously sheared within the measuring annulus which creates
viscous drag on the stator.
