Post-Season Checklist Helps Growers Tackle Needed Maintenance and Repairs

BEFORE SHUTTING down your irrigation system for the winter, experts suggest conducting a quick inspection – performing routine maintenance and making a plan for any necessary repairs.

“A thorough inspection can help identify potential problems that could result in costly delays or breakdowns next year,” said Evan Carlson, field engineer at Lindsay Corporation.

Valve Packing Friction: the Hidden Factor for Better Plant Performance

Pipeline rupture

IN MANY processes, valves are used as a way to control flow—but they also must seal leakage from the stuffing box and operate freely to keep the plant running properly.

Packing success and valve operability need accurate gland loading to perform correctly. Packing friction is a byproduct of tightening packing that needs to be compressed. If left unattended, issues can arise.

System Approach & Modeling Lead to a Reduced Impeller Diameter

Figure 1: Process system with one pump operating

EVERY ELEMENT found in a piping system falls into one of three categories: pump, process and control. The secret to understanding any piping system is to have detailed knowledge of the various pieces of equipment and how they work together.

For example, if a pump is not sized properly to meet the system’s process requirements, all the equipment within the system will be affected.

WHILE PERFORMING unnecessary oil changes is a waste of time and resources, never changing the oil is far worse.

Process pumps are often neglected when it comes to precision lubrication. Many maintenance and reliability professionals focus efforts on larger, more expensive machines, but these smaller components can be critical to process reliability, and the cost of repairs can add up.

Work Starts on $15 million Queensland Wastewater Treatment Plant

WORK HAS BEGUN on a new $15 million wastewater treatment plant in Cherbourg, Queensland, which includes new pump station infrastructure and irrigation system for one of Queensland’s largest indigenous communities.

Stage one of the wastewater infrastructure project began with earthworks for a series of ponds on a site away from the township entrance and homes.

How Efficient Is Your Pump System?

IN A HYPOTHETICAL world, if the Department of Energy (DOE) showed up at your plant to conduct an energy audit of the pump systems, what grade would you receive?

Do you get an A … or an F? Plant owners and managers are faced with balancing scores of urgent priorities every day—stock holders on one side demanding the plant run continuously to keep the profits high, and engineering (reliability) and maintenance on the opposite side screaming, “we need to shut down to fix the plant.”
