Pump Fixing
WARNING! If a rotor failure occurs, the connection of the pump to the system could be
subjected to a significant torque. If the connection is not sufficient to
withstand that torque, the pump could detach from the system or the motor
housing could detach from the pump envelope. In this case metal fragments
could be projected from the pump or system, which could cause serious
injury or death and/or damage to surrounding equipment.
Fix the TV 551/701 Navigator in a stable position, mounting the inlet
flange of the turbopump to the system counter-flange, with a
connection capable of withstanding a torque of 8600 Nm around its
axis. For example the ISO-K flange can be fixed using high strength
steel clamps (like Agilent model IC63250DCMZ).
The following table shows, for each flange, the necessary number of
IC63250DCMZ clamps and the relevant fixing torque.
Tab. 1
FLANGE N. FIXING TORQUE
ISO 160 10 35 Nm
ISO 200 12 35 Nm
The following table shows, for each ISO-F flange, the necessary
number of screws and the relevant fixing torque.
Tab. 2
FLANGE N. FIXING TORQUE
ISO 160 F 8 25 Nm
ISO 200 F 12 25 Nm
The class of the steel screws for "F" flange must be >= 8.8
The turbopump with ConFlat inlet flange must be fixed to the
vacuum chamber by means of the appropriate Agilent hardware. See
the appendix "Technical Information" for a detailed description.
