The Power of Rectifier Maintenance: A Case Study

We’ve published several articles on the basics of rectifier maintenance and the Preventative Maintenance (PM) packages that we offer. Today, let’s look at one of Dynapower’s recent visits to a manufacturing facility in Texas to see one of our PM programs in action.

Recently, Dynapower’s Repairs Supervisor Remington Schieffer traveled down to Texas with two other team members, Industrial Sales Rep Philip Points and the Regional Texas Service Technician Justin Kohler, to deliver information designed to improve a key client’s process and rectifier uptime.

Dynapower Launches New Preventative Maintenance Plans

A couple weeks ago, we published a piece on the different types of maintenance approaches for your rectifiers and industrial power systems. These included three types of maintenance: reactive maintenance, preventive maintenance and predictive maintenance.   

In this piece, we highlighted the disadvantages of adopting a purely reactive maintenance approach and shed some light on the benefits of adopting a preventive maintenance and ultimately, a predictive maintenance approach.

To recap, preventive maintenance is primarily based on anticipating failures and updates based on manufacturer recommendations while predictive maintenance is all about using data analysis to dial in your machines to achieve the maximum lifetime value out of them and give you the greatest process and product possible.

The 3 Types of Maintenance Approaches for Industrial Rectifiers

When it comes to preventative maintenance for industrial rectifiers, there are three levels that we most often see. By understanding these three levels of preventative maintenance and determining what category you fall into, you can begin thinking about how you can adopt new a higher-tiered strategy to save money and become more active rather than reactive. 

Level I: Reactive Maintenance 

The reactive form of preventive maintenance is akin to going in for an oil change every 3000 miles. You do it because that’s what you’re told to do. You don’t perform any checks or maintenance on your vehicle other than changing whatever the manufacturer tells you to change. 

The reactive maintenance approach basically involves taking action only when a problem has arisen. “When your equipment is down and there’s flames and smoke and downtime, you call us to fix it,” says Dynapower’s Repairs Supervisor Remington Schieffer.

Engineering Upgrades: A Breakdown of Our Touchpad and Touchscreen Controllers

At Dynapower, we refer to engineering upgrades as a term used to describe putting a non-original part in a machine as opposed to a repair—which refers to a like part for a like part exchange. An easy way to understand this is if you blow out your tire and replace it with the exact same tire it’s a repair whereas purchasing a higher end tire would be an upgrade.

Our main goal when considering engineering upgrades is determining how we can bring your piece of equipment that you know and love and are comfortable troubleshooting to the next level. When it comes to meeting today’s demand and production requirements, engineering upgrades to existing rectifiers are a great solution for a lot of customers.

SCR vs. SMPS Rectifiers: A Maintenance Perspective

Recently, we covered the three main considerations to weigh when buying a rectifier. Now, let’s dive a little deeper and shed some light a common debate in the world of rectifiers. We’re speaking of course about SCR vs SMPS rectifiers. As you will see, the ultimate differences and similarities may surprise you.

First, let’s run through the characteristics of these two classes of rectifiers. A silicon-controlled rectifier (SCR) is a semiconductor power supply that meters electricity by opening electrical “valves,” working together as a team, to rectify electricity. The longer the “valve” is open, the higher the voltage leaving the rectifier will be.

SCR rectifiers are variable voltage DC power supplies that are low frequency, high ripple systems. These systems are rugged and have a history of durability in the market – a number of our customers have systems running after 40 or 50 years. They regulate and react steadily, carry a lot of power in big copper windings, and are fairly easy to troubleshoot with large, easy-to-identify components.

Rectifier Repair, Engineering Upgrade & Refurbishment

Rectifiers can last decades before needing replacement. But not all parts used to build this essential piece of equipment have the same life expectancies. Some circuit boards or semiconductors degrade as part of their natural life cycle, and will need to be replaced several times in the rectifier system’s lifetime. Leaving parts at their end of life installed in the rectifier can lead to:

  • Loss of efficiency
  • Loss of communication capabilities
  • Loss of operator control
  • System failure
  • Injury or even death

When any of these conditions arise, companies need to assess the source of the issue and decide the best course of action. Customers have a variety of options to maintain their equipment. Some are by choice, and others by necessity.

Top 3 Considerations When Buying a New Rectifier

Rectifiers are power systems that convert alternating current (AC) to direct current (DC) power. The applications in which rectifiers are used are seemingly endless—with everything from metal finishing in the automotive and aerospace industries to mining, military defense and waste water treatment.

When it comes to purchasing a new rectifier or determining if it would be more cost effective to upgrade or refurbish, there are three main areas to consider: Process, environment and people.

 

Often, customers get lost in questions such as: Air vs. water-cooling? Switchmode or SCR type? Manual controls or PLC?

Like anything else in life, the more you put into researching and understanding the type of rectifier you need and more importantly why you need it—the more successful your operations will be.

Helping to Power the Copper Mining Industry

This week, Dynapower’s president, Adam Knudsen, visited ASARCO in Tucson, Arizona to discuss future projects.  A subsidiary of Groupo Mexico, one of the major copper producers in the world, ASARCO’s copper refinery process is powered by Dyanpower’s high power rectifier.

Dynapower is the world’s largest independent manufacturer of chopper and thyristor rectifiers for mining and electrowinning applications. Most electrowinning units consist of a tank, pump, and rectifier, making Dyanpower a key piece of the process. Copper ores are placed in the tank and electrolytic solution is pumped in. Dynapower’s rectifier shocks the tank with electrical current, and the ores come together to form large plates ready for market. Read more
