3.10.2 Maximum temperature of internals

For some material combinations the general temperature performances must be limited. The maximum allowable working temperature of internals depends on the combination of materials used and their thermal expansions and the interference fit to hold the bearing bush fixed.

•Some bush bearings have an extra locking screw. In this case the maximum allowable tempera- ture is based on the most probable interference fit.

•In case the bearing bush has no locking screw because material and construction do not allow concentrated stress the maximum allowable temperature is based on the minimum inter- ference fit.

The maximum allowable temperature of the rotor shaft bearing assembly is 280°C.

3.10.3 Operation under hydrodynamic lubrication conditions

Hydrodynamic lubrication could be important criteria for bush material selection.

If the bush bearings are running under the condition of hydrodynamic lubrication there is no more material contact between bush and pin or shaft and the lifetime cycle is increased significantly.

If there is no condition for hydrodynamic lubrication, the bush bearings make material contact with pin or shaft and the wear of these parts is to be considered.

The condition of hydrodynamic lubrication is fulfilled with the following equation:

Viscosity * shaft speed / diff.pressure ≥ K.hyd with: viscosity [mPa.s]

shaft speed [rpm] diff.pressure [bar]

K.hyd = design constant for each pump size.

3.10.4 Maximum torque of pump shaft and rotor material combination

The maximum torque is limited by the maxium transmittable torque of the magnetic coupling. This means the magnetic coupling will slip through before the rotor shaft or pump shaft reach their mechanical limitations.
