Energy-saving VFDs can induce electrical bearing damage in pump motors

Grounding ring part of solution for mitigating damage that can lead to premature failure
Through trial-and-error and much hard work, a Kansas motor repair shop says it has developed a virtually foolproof process for protecting vertical hollow-shaft motors from the electrical bearing damage caused by stray shaft currents.

Multi-shaft mixers in the food industry

Food manufacturers are seeing the benefits of ‘one-pot’ processing
A large portion of food-industry mixing operations are still accomplished by relatively simple single-shaft mixers such as propellers, pitched-blade turbines, impellers and anchor stirrers. Increasingly, however, food manufacturers are seeing the benefits of “one-pot processing,” especially when it comes to high-solids viscous applications that conventional mixers can’t handle.

Plastic connectors: Many factors weigh in when choosing the right ones

Metal connectors continue to be supplanted in many industrial and laboratory applications
Diverse challenges confront industrial and laboratory original equipment manufacturers (OEMs) in developing versatile, user-friendly, lightweight and cost-effective equipment and instrument solutions. One important, but not always fully appreciated, task is selecting tubing connectors for transfer and management of fluids and gases, particularly for mission-critical applications.

Where is that vibration coming from?

Production plant analyzes resonance anomaly; looks at condition monitoring program as a profit center
Sometimes in industry, mechanical “circumstances” change. When it happens, a machine train identical to other machine trains can suddenly become atypical. This was exactly the case for Process Water Supply Pump A, whose behavior was very similar to that of its sister pump trains, until something changed. In this article we discuss a problem that was abruptly encountered, the methods used to investigate it and the solution devised.

Clean pharmaceutical equipment based on TACT circle principles

Equipment design and cleaning procedures play big role in thorough sterilization and cleaning
Sterilization or sanitization procedures are typically meant to kill bacteria in a system. In addition, equipment is cleaned to remove residues from previous product batches and is subsequently flushed to remove cleaning liquids. But to ensure safe and efficient sterilization and cleaning, appropriate procedures aren’t enough. The right equipment improves cost efficiency, as well as patient safety.

Machinery bearing quality impacts energy costs

Indonesian textile plant tests lead to reduced energy consumption and lower operating costs
Not long ago, along with the rest of Indonesian industry, PT. Leuwijaya Utama Textile Co. (Leuwitex) was confronted with a government-enforced increase in electricity costs, in its case approximately 18%. The Bandung plant includes 300 textile weaving machines and 176 twisting machines, consuming 2,120 megawatt-hour (MWh) per month. This threat to bottom-line profitability had to be reduced.

Recent advances in pump technologies aid paint & coatings producers

Enhancements include ability to improve pump performance ratio, reducing compressed air consumption
While the first “paints” came from natural substances like charcoal, blood and berry juice, paints and coatings today are made of a wide variety of highly stylized components using high-tech manufacturing processes. In fact, most major enhancements in paint and coatings manufacturing have taken place in the last 25 years.

Castings company automates filling of etch baths with proprietary acid blends

Piping system makes double containment installation fast and easy
Chromalloy Castings, Tampa, Fla., recently replaced manual elements of a chemical-transfer etching process used to pre-clean parts with a semi-automatic transfer system. Using an overhead double-containment piping system for chemical conveyance, safety is improved by limiting the possibility of chemical exposure. Employees
