Agilent Technologies Mini Task AG81 Turbo Pumping System, KF40, G8703A / 9699180
Mini Task AG81 / G8703A Overview:
The Agilent Mini-TASK AG81 pumping system consists of a pump with an integrated controller and a forepump.
Turbo Pump Description:
The turbopump consists of a high frequency motor driving a turbine fitted with 10 bladed stages and 3 Macrotorr stages. The turbine rotates in an anticlockwise direction when viewed from the high vacuum flange end.
The 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 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.
The Macrotorr stators are in the form of selfpositioning machined discs with pumping channels and an opening restricted by the corresponding rotor discs. These are fabricated in aluminium alloy.
During normal operation, the motor functions with a power feed at 54 Vac three-phase at 1330 Hz. To reduce losses during start-up to a minimum, the frequency increases according to a ramp with a higher initial voltage/frequency ratio.
A thermistor sensor is mounted near the upper bearing to prevent the pump from overheating.
The pump is balanced after assembly with a residual vibration amplitude less than 0.01 µm.
Controller Description:
The integrated controller is a solid-state frequency converter which is driven by a single chip microcomputer and is composed of a PCB which includes a power supply with a 3-phase AC output, analog and input/output section, microprocessor and digital section. The controller recognizes the mains presence and converts the single phase AC mains supply into a 3-phase, medium frequency output which is required to power the pump.
The controller can be operated by a remote host computer via the serial connection.
Diaphragm Forepump Description:
The pump consists of an electric DC motor driving an eccentric which moves an elastic diaphragm.
The pump has four heads.
The compression chamber is hermetically separated from the drive mechanism by means of the diaphragm.
The pump transfers, evacuates and compresses completely oil-free.
The motor is supplied with a voltage of 24 Vdc.
