4.6 Configuration and function
Fig. 6: Amacan with axial propeller
The pump is designed with an axial fluid inlet and an axial outlet. The hydraulic
system sits on the extended motor shaft. The shaft runs in common bearings.
The fluid enters the pump axially via a suction nozzle (bellmouth) (1) and is
accelerated in a rotating flow by the rotating impeller (2). The required energy is
transmitted from the electric motor (4) to the impeller (2) via the shaft (5). In the
diffuser casing (3) the kinetic energy of the fluid is converted into pressure energy.
The rotational movement diverts the fluid flow into an axial flow. The shaft passage
through the casing is sealed towards the fluid with a shaft seal (10). The shaft (5) runs
in two rolling element bearings (6 and 8), which are supported by the bearing
housing (9) and the bearing bracket (7).
The pump is sealed by two bi-directional mechanical seals in tandem arrangement.
A lubricant chamber in-between the seals ensures cooling and lubrication of the
mechanical seals.
The pump sets are equipped with various sensors.
Standard
▪
Temperature monitoring of the motor
▪
Temperature monitoring at the lower bearing
▪
Leakage monitoring of the mechanical seal system
▪
Leakage sensors in the motor/connection space
Optional
▪
Temperature monitoring at the upper bearing
