1. Top Assembly.
The top assembly of the
apparatus consists of the chamber lid,
Standard Needle Valve, Calibration Needle
Valve, Hydraulic Fluid Cylinder and Grease
Cylinder Chamber. Refer to section 4.2 for
detailed descriptions on this section of the
apparatus.
2. Refrigerated
Test
Chamber.
Provides
environment for apparent viscosity test to be
performed at low temperatures down to -54°C.
3. Receiver Chamber.
For collecting grease
sample after being forced through cylinder.
Thermocouple
port
located
here
for
connection to RTD probe to measure grease
sample temperature inside cylinder. Chamber
has sufficient work space for interchanging
grease capillaries during testing.
4. Control Box.
For control of the refrigeration
and hydraulic system of the apparatus. Refer
to section 4.3 for detailed descriptions.
5. Gear Box and Motor Assembly.
This section
of the apparatus contains the gear pump,
gears, drive motor required to power the
hydraulic system. Refer to section 4.4 for
detailed descriptions on this section of the
apparatus.

6. Pressure Gauge:
Displays pressure required
for hydraulic system to dispense grease or
other sample through capillary. Gauges are
easily
interchangeable
for
pressure
measurements of various magnitudes.
7. Hydraulic
Oil
Reservoir:
For
filling,
replenishing
or
changing
hydraulic
oil.
Reservoir has clear viewing window that
allows the user to observe the flow of oil
during testing. The top of the reservoir
chamber can be removed easily to fill or
remove hydraulic oil.
8. Left-Hand Needle Valve Knob:
Part of dual
valve
hydraulic
system
designed
for
continuous flow of hydraulic fluid. Turning left-
hand knob counter-clockwise opens valve and
allows for fluid to flow through the open loop
system. Closing Left-Hand Valve by turning
knob clockwise closes the system loop and
forces the fluid to pressurize grease cylinder.
NOTE:
The two valve system (Left and Right-
hand Knobs) must be used in opposition.
When one valve is open, the other must be
closed, and vice-versa.
WARNING:
Never close both valves at
the same time as this will result in pressure
