Vent Device Mod. 969-9831; Vibration Isolator Installation; Single Damper; Double Damper - Agilent Technologies Varian TV 1001SEM Bedienungshandbuch

Vent Device mod. 969-9831

The vent device has adjustable delay time (up to
36 min.). This value can be used only with rack
controller.
To install the vent device unscrew and remove the
threaded plug (see figure below).
Screw the flange mod. 969-9108 on the pump, tak-
ing care of the o-ring right position.
Assemble the seal ring and lock the vent device in
position using the KF klamp.

VIBRATION ISOLATOR INSTALLATION

Single Damper

Two vibration isolators for ISO 200K and ISO 200F
inlet flange version pumps are available as acces-
sories.
The two model part numbers are the following:
−
model 969-9346 for ISO 200K flange;
−
model 969-9374 for ISO 200F flange.
They typically reduce the vibration transmitted
from the TV 1001 SEM to the system by a factor G
that depends on vibration frequency. In the follow-
ing table you can find the values of G for the most
relevant peaks in the pump vibration spectrum.
PEAKS
Cages
Unbalance
Where "axial" is the same axis as spin axis of the
rotor, and radial is perpendicular to it.
For more information please refer to the relevant
instruction manual.

Double Damper

If you need an higher damping factor (lower vibra-
tion transmitted from pump to system) you can as-
semble the pump with a series of two single
dampers (for more information please refer to the
relevant instruction manual).
In the following table you can find the typical val-
ues of the damping factor (G) for the double
damper.
