Capability Spotlight: Rethink Your Parts Strategy

The Critical Parts Landscape is Changing.

With the advent of innovative pattern making and additive manufacturing, end users have more options than ever before when it comes to parts supply. When faced with these exciting changes, it is important to develop a parts strategy that takes advantage of new technology while still reducing risk of component failure or unsuitability.

At Hydro Parts Solutions, we combine innovation with hard-earned experience in pump engineering, reverse engineering, materials, and casting.  Knowing that reverse engineering is far more complex than laser scanning and replication, they rely heavily on this experience and the knowledge of Hydro’s engineering network to verify critical dimensions, account for wear of the scanned component, upgrade tolerances, and provide a part that is better than the original.

By cultivating strong relationships with local foundries, Hydro Parts Solutions can provide expedited lead times while maintaining control of product quality throughout the manufacturing process. They adhere to strict process control procedures, including providing standardized parts numbers and generating drawings for every part.

Every job completed by Hydro Parts Solutions is passed through multiple levels of engineering and inspection checks, from model development through pattern creation to final machining and equivalency analysis.   This gives you confidence that the parts supplied will provide safe and reliable service.

As pump experts, Hydro has the experience to reverse engineer and supply complex hydraulic components and the resources to diagnose design problems and suggest targeted upgrades. Hydro routinely upgrades vintage equipment with proven design component design upgrades that counteract known failure modes. Our global engineering team works closely with our parts division to perform hydraulic modifications that increase efficiency or help end users meet changed system requirements.

The end result? Shorter lead times and longer component life.

State of the Art Parts- Rerated Impeller

Hydro Parts Solutions recently manufactured three impellers for a rerate project being developed through Hydro’s Rocky Mountain service center in Denver, CO. Hydro Global Engineering determined the new hydraulic design for the rerated pump, which required modifications to the casing and new impellers.

 

The end user chose to have the new impellers manufactured out of CA6NM using investment casting, which provides a smoother surface finish to slightly increase the impeller efficiency. Hydro Parts Solutions drove the project from casting package design through final machining, with the impellers being cast and finish-machined within 6 weeks.

The new pump design was successfully tested at Hydro’s performance test lab, validating the new hydraulics. The custom performance will help the midstream end user achieve their desired system flow with maximum reliability and minimum energy usage.

Engineering is at the Heart of Hydro Inc.’s Aftermarket Services

Hydro Inc. has a strong engineering capability and an expansive global reach in the pump industry, especially in aftermarket services. Pump Engineer had the pleasure of speaking with George Harris, Chief Executive Officer and Founder of Hydro Inc., where he discussed the company’s recent research initiatives, reliability support for customers, customized designs and the significance of upgrades and health audits.

“We were very fortunate that early in the company’s development we had the good fortune to work closely with Dr. Elemer Makay, a foremost consultant to the power generation industry and a specialist in troubleshooting multi-stage, high energy pumps”, states Harris. “Engineering combined with meticulous observation and analysis in the field were key to his troubleshooting process. As a result of his training over a twenty year period, engineering became the focus and strength of Hydro Inc.’s aftermarket services”.

According to Hydraulic Institute statistics, 85% of the critical pumps in industries, such as power, refineries and pipelines, are custom designed for the specific application intended. In order to properly rebuild, upgrade or troubleshoot these installations requires a solid aftermarket engineering capability and experience. Not only must the engineer understand pump fundamentals, but also the application and system in which the pump is being used, as well as the changes that may have occurred in plant operating conditions since the pump was originally installed.

Advanced Engineering Boosts Reliability in Boiler Feed Pump

This approach incorporated reverse engineering, design verification and casting simulation to address equipment failure.

Pump technology requires the extensive use of castings to form the complex shapes needed to guide process fluids through the machine. The shape of these passages is crucial to the machine’s performance.

Pump designers spend extensive time designing and optimizing the shapes of these passages to optimize the machine’s efficiency. Unfortunately, casting processes cannot always represent the pump engineer’s true design intent, and the manufacturing processes have a direct impact on the machine’s reliability and design integrity. Designers take these processes into account when proposing their designs, but sometimes the deficiencies of the casting process become apparent after a major equipment failure.

One example involved determining the root cause behind the first-stage failure of a Worthington 12-WCND-166 six-stage boiler feed pump. The pump exhibited high vibration and performance degradation, and it was taken out of service. The inspection determined that a crack had resulted from a welded core plug. Continue reading
