1.5 System Description – Mechanical (Puller Anatomy)
1.5.1 Some Basic Information
This section presents a basic mechanical description of the P-97, with particular emphasis on
terminology. Knowing the names of the various parts greatly facilitates communication
between the investigators and the manufacturer when discussing adjustments or service
problems. In addition, various controls and adjustments on the top of the instrument are
located and described. Those adjustments, which are considered part of maintenance
procedures, are dealt with in the Maintenance Section of this manual.
1.5.2 Air Cooling System
The Model P-97 supplies a blast of air to cool the filament area after the heating segment of a
pull cycle. The components of the air-cooling system are shown below.
Figure 1-3. P-97 base plate (top view, cover removed).
Air
Compressor The air compressor (or pump) creates the air pressure used to cool the
filament and glass during the pull cycle.
Air Jet Directs the cooling air to the filament. The air jet should be positioned 2 to 3
millimeters below the filament. The screw that secures the air jet to the
filament block can be loosened allowing the jet to move up and down.
Air Valve
Solenoid Regulates the flow of cooling air to the filament and glass.
Drierite
Canister
(Reservoir
Tank) A canister filled with Drierite used to remove moisture from the air flowing
between the pump and the air solenoid. The dissected air is used to purge
the Humidity Control Chamber before and after a pull, allowing the flow of
dry air to cool the filament and glass during the pull cycle.
1.5.3 Heating Assembly
The Heating Assembly comprises the Filament, Filament Block Assembly, and the Humidity
Control Chamber. The Filament Block Assembly and the Humidity Control Chamber are
discussed below. Filaments are discussed in a separate section.
