A large pulp mill was shut down due to failure of the forced draft fan on its recovery boiler. Excessive vibration of the inboard bearing had broken the cooling water line inside the oil-filled bearing housing and flushed out the oil. The bearing journal had overheated, cracked and melted the Babbitt causing heavy scouring damage to the shaft surface.
Performance monitoring is not new. The concept of regular reporting has been around for as long as manufacturing operations have been in place. However, the pursuit of real-time performance management (RPM) requires managers to actively consider which metrics effectively track key processes and enable process improvements.
The array will reduce electric usage at its North America headquarters facility by an estimated 2%-3% annually.
Seeing the advantages machine vision provides in automation environments isn’t difficult. Inspecting products on the line saves the costs and consequences of recalled items, and properly labeling items before shipping ensures customers receive the correct product – a critical concern in the food, beverage and pharmaceutical industries.
A proactive approach to a skills deficiency is imperative for a company hoping to remain competitive. Let's face it, many industrial companies will be competing for the same group of skilled workers in the future. Here are five steps to help you survive a pending skill shortage in your company.
3D modeling offers a deeper vision of plant operations
Several options exist to mitigate harmonic problems in plants. Unfortunately, there is no one solution that fits all applications. Finding and choosing the correct option for your needs is the key. Otherwise, failure to reduce these unwanted electrical currents can result in problems ranging from overheating neutral conductors and transformers to inefficient operation of electronic equipment.
Adjustable speed drives can be used in most applications where motors power mechanical equipment. Drives provide precise electrical motor control, enabling motor speeds to be ramped up and down or maintained at a required speed. The obvious benefit is the motor and drive use only the require amount of energy, rather than having a motor run at a fixed speed.
A PLC for process control can appear to be less expensive, but… Bill Lydon, contributing editor at Automation.com has talked with a number of control engineers that are trying to sort out this issue to make decisions.
