Capability Spotlight: Adopt a Higher Standard

Posted on

Improving performance and life isn’t always about making big changes to design and operation. Small improvements to the standards and processes that are used during refurbishment and assembly can result in outsized benefits.

Hydro specifies machining and fit-up tolerances that often exceed the required industry standards and are best-in-class for the pump industry. Taking the extra time to meet more stringent tolerances ensures better concentricity and parallelism of critical components, reducing the risk of contact between the rotating and stationary elements during operation. Reducing component contact will result in reduced vibration and reduce the rate of wear for close clearance components. Maintaining design clearances greatly contributes to longer mean-time-between-repairs by providing greater stiffness and damping to the rotating assembly and reducing internal recirculation, which in turn affects performance and efficiency. To learn more about the importance of maintaining design clearances, read our Hydro Learning Hub white paper on the subject.

Another improvement that is standard at Hydro for repairs of multistage barrel (BB5) pumps is a dimensional analysis to identify relative centerlines of all impellers to their respective diffusers. This process and the resulting actions to ensure centerline compatibility at each stage are essential in prolonging equipment life and counteracting latent failure mechanisms.

By adhering to stricter tolerances, requiring robust process documentation, and never cutting corners, Hydro’s rebuild process results in greater reliability and increased mean-time-between-repairs. This level of quality ensures a safer work environment for our end user customers, reduces waste by decreasing the frequency of maintenance cycles, and lowers overall cost of ownership.

Capability Spotlight: High Capacity Pumps

From lifting massive weights, to reverse engineering components with expansive surface areas, to troubleshooting vibration in machines susceptible to resonance problems, large vertical pumps have unique challenges. Fortunately, Hydro has cultivated specialized capabilities to meet these challenges.

The first challenge is gathering dimensional data and providing reliable, quality parts supply. Large pumps are expensive to ship off-site and often run without a spare. Being able to capture precision measurements of critical parts on-site reduces both cost and risk. Hydro’s reverse engineering team is experienced in how to efficiently and accurately reverse engineer large components.

The field portion of the reverse engineering process for a large part can usually be accomplished in less than a day. After the measurements are taken, the pump can be returned to service while the model is completed and the part is manufactured.

Taking the initial component data is only the first step in Hydro’s reverse engineering process. Using their experience in the failure modes and upgrades of large pump designs, the reverse engineering team will recommend component upgrades or improved metallurgy to extend the life of the part. Where appropriate, they will also identify methods of refurbishment that can return a large part to reliable service in place of supplying a new component.

Another challenge when working on large pumps is that they require a shop with the appropriate tooling and lifting capacity. It also requires a team dedicated to providing a higher standard of repair. Because vertical pumps are made of several stacked components, maintaining tight tolerances and best-in-class fit-ups is critical for reliable operation. Hydro’s standards are more stringent than those required by any industry body. This translates to longer life, better performance, and safer operation.

Maintenance documentation varies widely in quality, often being incomplete, vague, or outdated. Procedures may lack detail, rely on obsolete methods, or feature unclear diagrams. Sometimes these procedures are taken from OEM manuals, which are too generic and require design knowledge to understand which steps are applicable.

For many years, maintenance crews have been relying on the experience of their workforce to perform the work correctly despite poor instructions. However, mass retirement from an aging workforce, higher employee turnover rates, and leaner staffs have taken away this safety net of experience and leave our facilities at risk. One of the greatest risks to the safe and profitable operation of our plants is preventable errors that result in online equipment failure.

A maintenance procedure that is optimized for the world we live in now has different requirements than the procedures developed in the past.  Firstly, it needs to adequately capture the institutional knowledge of skilled professionals who are familiar with the equipment. Secondly, it needs to clearly illustrate each step in the procedure in a way that is easy to follow. Thirdly, it needs to accurately reproduce the design of the installed equipment instead of being overly generic. Lastly, it needs to be delivered in a format that reflects how the new generation of workers consume information- digital and interactive.

The last requirement may seem like more of a ‘want’ than a ‘need,’ but it is just as critical as the other three. Most workers who have graduated in the past 10-15 years are what are commonly referred to as ‘digital natives’ and have been immersed in a learning environment that depends heavily on digital assets.  Providing information in a way that is intuitive for them to use and matches the way they are used to interacting with information will help them retain that information and complete work more efficiently. This not only supports reducing risk for maintenance errors, it streamlines the work completed to save on labor hours needed for each job.

Hydro has addressed this need by developing IMPEL, an interactive, digital maintenance platform that replicates pump design and installation to clearly illustrate each step of the maintenance procedure. IMPEL uses an interactive 3D model of the equipment that is animated to illustrate each step of the maintenance procedure. Part of the development process includes an extensive overview of the procedure by Hydro’s experienced field service technicians to ensure that it includes best practices and to add notes and warnings into critical steps where mistakes may be made.

Hydro University was developed with a mission of ensuring that pump users around the world have access to the knowledge required to optimize industrial operations and reduce pump lifecycle costs. By imparting technical skills, pump knowledge, and troubleshooting methodologies, we help our customers to achieve this.

Hydro has spent 50 years accumulating knowledge of pump operation, maintenance, troubleshooting, and upgrades. Our aftermarket perspective uniquely empowers us to look at our pumps the way an end user would- with an eye for improving reliability and performance of existing assets instead of a focus on initial design. Our training is similarly focused on imparting skills critical to end users’ every day job functions instead of theoretical design that would rarely, if ever, be used by pump system owners.
