Varian TV-70LP Turbo Pump
The Varian/Agilent TV 70 LP turbo pump. The pumping speed up to 68 l/s N2. Varian TV 70 LP(9699365) has the compression ratio 5 x 108. The weight of Agilent TV 70 LP is 1.7 kg. Rotational speed is about 75000 rpm.
The Varian V70LP pump consists of a high frequency motor driving a turbine fitted with 10 bladed stages and 4 Macrotorr stages. The turbine rotates in an anticlockwise direction when viewed from the high vacuum flange end.
The TV70LP / 969-9365 turbine is made of high-strength, light aluminium alloy, and is machined from a single block of aluminium. The turbine blades have five different angles, from 44° to 12°, while the Macrotorr stages are in the form of discs.
The V-70LP 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 fabricated in stainless steel. These are supported and accurately positioned by spacer rings.
During normal operation, the V-70lp motor functions with a power feed at 54 Vac three-phase at 1250 Hz. To reduce losses during start-up to a minimum, the frequency increases according to a ramp with a higher initial voltage/frequency ratio.
