The Situation
Gearboxes being used within a large water treatment works were now obsolete, which meant that replacement components were no longer available when issues arose. During their years of operation, the bearings, seals and gears on these units had been repaired many times, and so a complete overhaul was required.
The Solution
After a site visit and close consultation with the customer, the HAYLEY DEXIS team developed a solution that was fit for purpose. They offered a modern replacement with an inverter to provide improved reliability. The new units specified by HAYLEY DEXIS incorporated the same dimensions as the existing units, enabling a quick and painless changeover for the customer. HAYLEY DEXIS engineers replaced all bearings, seals, shafts, and bearing blocks. They dressed and polished all gears and replaced all chains and sprockets. Additionally, the main drive gearbox was replaced with a more energy-efficient unit.
"THE RELIABILITY OF THE GEARBOXES AND THE AVAILABILITY OF SPARES HAVE BEEN IMPROVED."
The Result
The new, more efficient motors have reduced energy consumption, costs, and the operation’s carbon footprint for the customer. The new units are also capable of transmitting more power and torque to handle heavier loads, reducing the risk of overloading and potential failure. The reliability of the gearboxes and the availability of spare parts have been significantly improved by using a modern unit with better mechanical service factors.
