◇ Depending upon the type of the auxiliary pump used, atmospher ic air may
reverse flow into the STP pump when t he auxiliar y pump stops. Attach a vacuum valve to the middle of the piping betw een t he STP pump outlet port flange and the auxiliary pump, and close the va cuum valve when the auxiliary pump stops.
In order to let the STP pump bring its performance into full play, f ollow t he precautions below:
1) Be careful not to scratch the flange of the STP pump.
Before installing the STP pump, check whether or not there are scratches on the surface.
2) Use steel or aluminum tubes with a low gas loss to connect the vacuum
equipment to the STP pump.
3) Take measures for minimizing leakage. It is also necessary to degrease the
tubes as regularly as possible to keep the gas loss as low as possible.
4) It is recommended to use an auxiliary pump of 240 L/min or more. However,
the pressure at the inlet and outlet ports varies with the flow rate of gas, capacity of the vacuum equipment, length and material of the piping. Select an auxiliary pump in accordance with the capacity and starting method (simultaneous starting, starting after ge nerating roug hing v acuum ) suit able f or the vacuum equipment you use.
5) Connect the STP pump and the auxiliary pump using stainless steel or
aluminum alloy tubing, flexible tubing, vacuum rubber or Tef lon tubing , et c. The following measures can be used to avoid the transmission of the vibration of the auxiliary pump to the STP pump and the vacuum equipment .
· DO NOT place the auxiliary pump on the same floor as the vacuum equipment.
· Locate the auxiliary pump on a vibration-proof table.
· Attain 1/3 or less of the rotational speed of the auxiliary pump, when
adjusting the inherent frequency of the auxiliary pump installed on a vibration-proof table.
· Attach a weight to the piping from the aux iliary pum p, or secure the piping to a rigid, heavy object free of vibration.
· Use a tube of high flexibility.
6) Depending upon the type of the auxiliary pump used, oil vapor m a y contaminate the inside of the STP pump. Some oil viscosity could cause a malfunction when there is a strong reverse flow of oil. Take the following measures to ensure the correct flow of oil:
· Attach a vacuum valve to the middle of the piping between the STP pump
outlet port flange and the auxiliary pump.
· Attach an absorption trap adjacent to the vacuum valve.

STP-H600/H1000 Series Instruction Manual
11 Operation Principle of the STP Pump
The STP-H600/H1000 is a series of magnetically-levitated turbomolecular pumps, featuring the following:
l Oil free l Low vibration l High reliability
The STP pump is configured so that rotor blade (1) and stator blade (2) are aligned alternately in the axial direction. Gas molecules are pumped from the inlet port to the outlet port by the high speed rotation of the rotor. By uniting the rotor blades and the sleeve lower, the STP pump has a large capacity allowing it to be used in a wide variety of applications. Rotor blade (1) is supported by the magnetic bearing without mechanical contact. Therefore, the STP pump requires no lubrication oil unlike conventional turbomolecular pumps using ball bearings. The magnetic bearing consists of 5 pairs of active magnetic bearings. The rotor is supported in the radial direction by 4 pairs of radial direction active magnetic bearings that consist of radial sensor (3) and radial electromagnet (4). A pair of axial direction active magnetic bearings consists of axial sensor (5) and axial electromagnet (6 ) to support the rotor in the axial direction. Because the rotor is supported without mechanical contact, it can rotate at low vibration. There is less heat generated from magnetic bearings because there is no friction. Therefore the STP pump requires no cooling. However, the STP pump requires water cooling during baking and gas suction. Taking into consideration a breakage of magnetic bearings, touch down bearings (7) and (8) coated with solid lubrication have been installed. They do not contact with the rotor during the rated operation. A radial direction sensor, a rotation sensor and a temperature sensor always monitor the magnetic bearing as well as the rotor. If an abnormality/error occurs, the rotor will stop.
