Years of research in the field of fluid dynamics have been utilized in developing the Plenty Side Entry Propeller
|
The Design parameters are unique to side entry mixing:
Minimum Diameter - to permit ease of installation through standard manholes so that fully assembled mixers can be fitted from the outside of tanks - personnel do not require to enter tanks to fit the propeller. Smaller diameter also permit floating roofs to come lower in the tank producing lower ullage loss.
No Cavitation - by necessity a side entry propeller is located close to the tank wall. Some high pumping propellers have a tendency to cavitate due to restricted flow paths behind the propeller blades. This can lead to premature tank wear, wasted energy and resultant low flows.
High Concentrated Thrust - to reach across large diameter storage tanks a concentrated mixing' beam is required. Just as a parabolic reflector will emit light beams a long way, a side entry propeller must project the thrust a long distance.
High Fluid Flow - process performance is normally a function of propeller flows. Minimal mixing time is achieved with a high performance propeller.
Minimum Power Draw - the design objective is to achieve all the above with the minimum use of energy.
Study the Plenty Propeller - there is no other propeller available today which is more suited to side entry tank mixing.
The Plenty propeller is a true helical pitch propeller with forward rake. The forward rake is unique to Plenty Mixers and is most significant in meeting the above design parameters.
This design provides for optimum cavitation free suction conditions whilst promoting maximum fluid pumping and entrainment for any installed power.
Each propeller is accurately cast as a one piece component, thus eliminating the pitch setting variances and welding problems often present with fabricated designs.
Rigid inspection of pitch uniformity, static, dynamic and hydraulic balancing ensures vibration free operation. No propeller or side entry mixer leaves the Plenty factory without first undergoing quality control approval in the test tanks.
