Starting can have a significant effect on the life of the winding insulation of an AC motor.

Frequency Hopping Spread Spectrum (FHSS) radio was invented during World War II by the military for communicating information and strategic plans to allied forces in a way that would counter enemy efforts to "jam" or intercept traditional radio communication frequencies.

Holistic pump system designs optimize system efficiency and life cycle performance.

The service department of a variable frequency drives manufacturer frequently sees the following scenario: A frustrated user calls with what he perceives to be a defective piece of equipment. As the technician begins probing for information, the user's frustration boils over, often with an exclamation along the lines of "what a piece of junk!" As the service technician asks the pertinent questions, the exasperated user relays the details of a drive that is continually tripping on a fault until the user is at the end of his rope, not knowing what to do.

One of the most neglected tools in the vibration analysis toolbox is phase. This neglect is partially due to the extra time and effort often necessary to collect the information. Many analysts are also not properly trained in phase measurement and analysis.

Introduced in August 2008, the Retroflo RPC_2000 Pump Control System was designed to control pump stations as a whole, rather than just the individual components within them. Through continuous dynamic monitoring of the characteristics through a range of wet well levels and pump speeds, the system uses the full range of pumping data available to optimize performance. It can be retrofitted to existing stations or installed in new stations.

Use of disposable components in product downstream processing and final fill operations is increasing as technology improves for performing these steps in a single-use mode. There is a high demand for systems that support single-use purification, formulation and filling operations.

Increased efficiency, higher air handling and fast, automatic priming are provided with new technology.

Last month we reviewed the pump selection criteria for a closed loop circulation system (Vp-Vf). This month we will take a look at a similar application that adds some elevation to the equation.

Questions are answered about monitoring power consumption and noise level parameters for pumps.

Balancing is essential for minimizing vibration, increasing bearing life and minimizing downtime and repair costs. Follow the guidelines from these standards to balance centrifugal pumps properly.

While scheduled downtime is different from unscheduled, both can take away from a company.

Picture a manufacturing enterprise with plants in multiple locations around the world. Using a single automation platform that handles discrete, process and motion control with common programming, human machine interface (HMI) and standards-based networks, a night shift operator gathers and logs data on product quality from his production line.

Most VFD systems use some form of closed-loop feedback to avoid surging, excessive noise, and in extreme cases, vibration. A reliable encoder signal is one method that minimizes speed variance and helps eliminate these unwanted effects. Here's how it works.

The 4-20mA current loop is used to transmit analog data representing various process variables like level, pressure, temperature or flow. Although conceptually simple, a 4-20mA current loop can be tricky to troubleshoot. Current flows in a single direction through each device in the loop.

The past may be prologue to the future, but the time between the two seems increasingly short. In the past, labor, capital and raw materials were considered the underpinnings of wealth creation. Today, real-time process knowledge and innovative management strategies have become far more important for creating value, as evident in the headlines above. Accordingly, the time for systemic change is now. . . the opportunity to reinvent industrial manufacturing and the products and services that surround it have never been greater since the beginning of the industrial revolution.

An automated monitor provides a live, continuous picture of exactly what is happening inside a turbine for protection, prediction, performance monitoring, and integration of the data with process control.

VFDs replace mechanical devices and PLCs for lead-lag pump control.

How a monitoring alarm system with control and shutdown capabilities prevented costly pump damage and environmental hazards and made the job of the pump operator safer and easier.
