Process Control

Understanding and maximizing process stability Fluid handling plants operate at a specified process setpoint (usually flowrate, pressure, or temperature). The pumping system must guarantee that the actual operating point matches the desired setpoint. To do so, the pump speed must be accurately adapted to react to disturbances in the system, or to changes in setpoint. […]

Fan Stability

// BLOCKER FOR COVER PICTURE Understand how to maximize stability Motor with outer rotor design are intrinsically prone to mechanical instability. Fans and compressors can stall (an aerodynamic instability phenomenon). Levitronix BFS are therefore susceptible to both. To maximize performance and uptime, it is important to understand sources and consequences of instability. In this lesson […]

Noise

//BLOCKER FOR TITLE PICTURE Understanding how noise is generated, measured, and transmitted Levitronix fans generate noise due to the interaction with the air flow, and the magnetic fields in the motor. This noise can become a work hazard if it is too loud, therefore it is important to understand the origin and transmission of noise, […]

Pumping in Series and Parallel

Understanding how complex pumping systems perform, and why they are needed Certain industrial processes require challenging combinations of flow rate and pressure, which cannot be achieved using a single pump. In these cases, it might be necessary to use multiple pumps arranged either in series or in parallel. Redundancy in the system is another common […]

Energy Flows and Efficiency

Understanding how energy is converted and transmitted Levitronix pumps absorb electrical power from the grid and, after a few conversions, deliver deliver part of it as hydraulic power. A pumping system is composed of different elements which transmit and convert power, generating losses as well. Understanding the sources of losses and the resulting conversion efficiency […]

Priming

Understanding and avoiding priming issues Priming is a necessary step to operate centrifugal pumps. Failing to perform proper priming will result in dry running and poor pump performance. Priming problems can be prevented by properly designing the hydraulic setup. When the guidelines cannot be strictly followed, it is still possible to operate the system by […]
