3. Installation
3.1. Preparations For Installation
Do not carry out any unauthorised conversions
or alterations to the turbopump.
The operator must ensure that the TC 600 is inte-
grated into an emergency safety circuit. The
supply voltage of the TC 600 must be interrupted
when releasing the emergency safety condition.
For special requirements please contact Pfeiffer
Vacuum.
– The maximum permissible rotor temperature of the pump is
80 °C. If the vacuum chamber or parts in the vacuum
chamber are heated must be fitted if necessary, suitable
shielding in the vacuum chamber before the turbopump
(constructional suggestions available on request).
– The temperature of the high vacuum flange may not exeed
120 °C.
– Only remove the blank flange from the high and fore-vacu-
um side immediately before connection.
– On Turbopumps TMH 071 P/TMU 071 P the lubricant reser-
voir is already fitted and filled.
– Where magnetic fields of > 3 mT are involved suitable
shielding must be provided (available on request).
– If the pump is baked out, the heating sleeve and the body
of the pump must be insulated to prevent burns from
accidental contact.
– In the event of a sudden standstill of the rotor, torques of
up to 330 Nm can arise and these must be taken up by the
turbopump and frame. Pumps must be anchored as
follows:
– ISO flange with 4 bracket screws, or
– CF flange with the complete set of M8 screws, or
– Underside of the pump with 4 screws M5,
screws quality 8.8.
– Either air or water cooling is necessary for operating the
pump. Where operations with convection cooling are
involved, a cooling unit must be used (please see
"Accessories")
WARNING
3.2. Installing The Pump,
Connecting The High Vacuum Side
The utmost cleanliness must be observed
when fitting all high vacuum parts. Unclean
components prolong the pumping time.
Using the splinter shield
The use of a splinter shield in the high vacuum flange
protects the turbopump against foreign bodies coming from
the vacuum chamber but does reduce the volume flow rate of
the pump by approximately 15%.
For fitting splinter shields please refer to “Fitting the splinter
shield”.
The high vacuum side can be flanged onto the the vacuum
chamber directly or via a Pfeiffer Vacuum bellows or a vibra-
tion compensator (see ”Accessories”).
Connecting via a bellows
If the high vacuum side is to be flanged via a bellows, the tur-
bopump must be secured for example via the holes on the
underside of the turbopump must be secured for example via
the holes on the underside of the pump. The fastening must
be able to withstand the torque referred to in Section 3.1.
Connecting via a Pfeiffer Vacuum vibration compensator
Where a Pfeiffer Vacuum vibration compensator is in use, a
freely
suspended turbopump can be flanged onto the vacuum
chamber. Additional fastening is unnecessary.
The maximum permissible temperature at the
vibration compensator is 100 °C.
