Description of the Turbo-V 2300 TwisTorr
Pump Description
The pump consists of a high frequency motor driving a turbine fitted
with bladed stages. The turbine rotates in an anticlockwise direction
when viewed from the high vacuum flange end. The turbine rotor is
supported by permanently lubricated high precision ceramic ball
bearings installed on the forevacuum side of the pump.
The static blades of the stator are made of alumin-ium alloy. These
are supported and accurately positioned by spacer rings. A first
thermistor sensor is mounted near the upper bearing in order to read
the bearing temperature and to prevent the pump from overheating.
A second thermistor sensor is mounted near the water-cooling
channel in order to evaluate the cooling efficiency. The pump must be
always water cooled. For this purpose the customer must use the
dedicated channel on the pump body.
During normal operation, the motor is fed with a 60 Vac and 555 Hz
three-phase voltage. The power provided to the motor is limited by
the controller.
The pump is balanced after assembly with a residual vibration
amplitude less than 0.01 µm. The pump can operate in any position
and must be supported on the high vacuum flange. The connection of
the forevacuum on the side of the pump is a KF 40 NW flange.
