Skeleton crews, required social distancing, and more are effecting customer facilities across the MidWest. Outside help and expertise is needed more than ever.  Decatur Industrial understands our role in serving as an extension to your team.

This large integrated steel producer was experiencing water inside their 15HP DC motors which was resulting in emergency repairs due to water ingress. Our team repaired the failed motors quickly and provided Lexan covers allowing the customer maintenance personnel to visually check motors for unusual brush wear, commutator condition and water.

The customer was engaged to discuss solutions to reduce issues being seen on the motors. D.I.E. recommended that no silicone sealants be used on the motor covers to reduce brush swelling and recommended a sealant that would work best for the application. Plus:

• Add an additional bolt to each side of the Lexan covers
• Increase thickness of Lexan cover
• Use a non-silicone sealant

This simple modification resulted in decreases in motor failures and extended life expectancy of motors in service.

While we focus on protecting the health of our employees and their families, we also want to alleviate any business concerns you may have during this time. Our facility is open and continues to run multiple shifts; focusing on the social distancing of employees while working to repair and return your critical assets as quickly as possible.

In addition, we are encouraged to report that so far, none of our suppliers have reported delays in shipments or problems fulfilling orders due to COVID 19.

Decatur Industrial Saves Customer $40,000

The ability to recognize small problems before they become large ones is crucial.
Decatur Industrial Reliability Specialists are prepared to do just that for our customers.

Whether you have new employees not yet trained (the case in this situation) or employees unfamiliar with the more technical aspects of the equipment, we are here to help.  Recently, on a preventative maintenance inspection route at a large paper mill, our Reliability Specialist found one of the motors to be running extremely hot.

Upon closer inspection, he found the external blower was not operating.  He engaged the appropriate staff member and together they fixed the problem to cool off the motor before the imminent failure occurred.

If this issue had not been identified the motor shortly would have overheated and ran to failure, causing expensive production downtime. This customer saved a rewind and other work costing upwards of $40,000 in repair.

Decatur Industrial Works on Environmentally Friendly Retrofit & Upgrade

In an effort to go green, our customer’s facility is shutting down coal to steam operations. They have an MR compressor application that is driven by a steam turbine.  The process engineering team requested our assistance with motor application expertise and guidance in retrofitting to an electric motor driven solution for the existing compressor.

D.I.E collaborated with the customer’s engineering team on a motor and mounting adapter base solution to the existing compressor frame.   This solution needed to reliably function in a somewhat challenging environment.  We strategized in a team effort arriving at an adapter base and motor design that provided the required torque within the challenging thermal and dimensional limits available.  We determined that this application would require a 1500hp motor torque requirements with a very specialized adapter base.  The adapter base and motor will be built by the Siemens Above-NEMA (ANEMA) motor plant in Norwood, OH.  (story continues below picture.)

This upgrade will maximize their process efficiencies. Steam turbines are less efficient, compared to electric drive systems.  This is especially true when heat losses from steam are considered. Steam turbines also require more planned shutdowns, and due to their significant number of moving parts, are comparatively less reliable than electric motor drive systems. These advantages combine to maximize the customer’s equipment uptime and productivity.

Decatur Industrial would love to help your facility see what productivity gains you can achieve through similar upgrades.  Thanks to their efficiency, reliability, and attractive price points, electric motor variable speed drive systems are an attractive option.

Specifying 63 motors with horsepower ratings ranging from 2HP to 250HP to achieve the optimum performance and reliability at a true state-of-the-art distillery is a major undertaking for project engineers. Some of the hardest work comes in the beginning stages – researching, identifying the appropriate design, and then working with the motor prints and drawings.

As a valued solutions partner, D.I.E. was asked to support the project engineers in specifying designs including motors for custom applications. These applications required comprehensive VFD-Duty motor designs that the OEM could not provide.

Our customer required the exact drawings be included for each motor quoted in the project.
D.I.E. came up with an organizational method to make it more efficient for the engineers to review and approve the drawings – saving them time and resources and eliminating any confusion that could majorly affect the project.  

1. Simply clicking on the drawing number within the spreadsheet takes the engineers to a sheet with the exact motor drawing image.

2. Once at the drawing image sheet, double-clicking on the image will open it in ADOBE PDF. This allows our customer’s engineers to rapidly and accurately access the motor drawings for each application on the project.

Decatur Industrial Electric Takes on Double Drum Dryer Project
(Scroll to bottom for images!)

A Decatur Industrial customer was looking for a vendor to rebuild a piece of equipment for their joint venture partner. The turned to us – already one of their strategic partners with the ability to meet the demands and requirements:

1. Extensive mechanical and electrical knowledge
2. 35 ton crane capacity
3. Read and interpret OEM blueprints and electrical diagrams
4. Complete machining capabilities
5. Garage bay door up to 14’ wide and 16’ tall

This customer and their joint venture partner had a new product they wanted to create and sell; and couldn’t do so without a double drum dryer.  Our team of experts took the reins and handled the project from start to finish. This project was a perfect fit for our capabilities, especially in our machine shop. 

Utilizing the OEM manuals, we began with disassembly just like our typical process. However, unlike a typical motor, this disassembly process was much more complex as the number of components was multiplied. This project saw us disassembling and assembling: bearings, rolls, end plates, packing glands, gears, cutter arms, air cylinders, air lines, adjuster arms, sprayer arms, door clamps, and more.
Our machine shop also handled:

• Machining all rotating parts to within tolerances
• Repairing bearing journals on drums
• Manufacturing teflon brushings and bronze bushings

Weighing in at over 30,000 pounds and encompassing a footprint of 11 feet by 10 feet, this repair saved the customer $400,000 versus buying a refurbished one. The customer realized a significant cost savings.
