How to Track Large Rotating Equipment

Rotary dryers, kilns, mills and reactors turn on tires and trunnions. Each tire is mounted to the rotating shell and revolves on two roller trunnions. If the alignment between the tire and trunnions is lost due to wear, poor repair, installation error or impact, the equipment will need to be tracked.

The State of the Semiconductor Industry and Its Growth

The semiconductor industry is a cornerstone of modern technology, enabling innovations that make the world smarter, healthier, greener, and better connected. Semiconductors, often referred to as the “brains” of electronic devices, are integral to everything from smartphones and computers to advanced medical equipment and electric vehicles, as well as less common household items like refrigerators, dishwashers, and our smart bulbs to connect devices to Alexa or Siri.

A Look at Closed Cooling Water Issues

Large industrial facilities frequently have many closed cooling water systems. Plant personnel may, at times, overlook important issues related to water treatment and corrosion minimization within these networks; that is until a failure brings down a system and perhaps a unit operation, or worse. An important part of any preventive maintenance program is conscientious monitoring and control of cooling water chemistry.

Use the Right Grease for the Job

Grease – use the right one for the job. The classification, selection, and application of greases is included in this article. Greases are designed for specific applications and if used in the wrong service they will not be effective. Compare the properties of greases and check those used in your equipment are suited to the service.

Get Mechanical Seals Working Properly

Get mechanical seals working properly. Mechanical seals are used to keep the bulk contents of rotating equipment such as pumps and compressors from escaping. They do this by sealing the shaft that protrudes from the casing. They require quality installation and operation conditions for a long life. Keywords: precision assembly, barrier fluid, stationary seal, rotary seal, alignment.

Prevent Flange Leaks with Proper Bolting Practices

Prevent flange leaks with proper bolting practices. Bolts and gaskets behave like springs and unless flange bolts and nuts are properly tensioned the flange will leak. The correct tightening torque depends on bolt diameter, material of construction, process pressure and bolt fabrication.

Protecting Cooling Water Systems – Part 2

Cooling systems are vital and integral components at thousands of industrial plants. Properly designed and operated chemical treatment systems, preventive maintenance of such, and monitoring are absolutely critical to minimize failures that otherwise may cause partial or full plant outages. In the next three parts of this series, we will examine the water-side issues of microbiological fouling, scale formation, and corrosion that require attention during both the design and operation of open-recirculating cooling systems like those discussed in Part 1 of this series.

Protecting Cooling Water Systems – Part 1

In Part 1 of this series, we will examine some of the most important components of cooling towers, and from that will build upon issues that can affect cooling system performance and operation. One of the later installments will address closed cooling water systems.

High-efficiency SynRM motors, a game changer in potentially explosive environments

Safety is critical in this industry, especially for applications in potentially explosive environments. Introducing the new IE5 SynRM Increased Safety motors represents a game changer, giving chemical manufacturers access to the most energy-efficient motor and drive technology. The new motors offer up to 40 percent lower energy losses than commonly used IE3 motors while meeting stringent safety standards.
