Client: A Water Pumping Station
Industry: Water Utility and Infrastructure Management.
Issue: Client experienced pump imbalance issue caused by debris denting the impeller, resulting in elevated vibrations
Background
Maintaining the operational integrity of high-capacity water pumps is critical for ensuring uninterrupted water supply and avoiding costly downtime. Our client – a water pumping station, relied on a 3.3 kV deep well submersible pump, a pivotal component for large-volume water supply. Given the importance of this equipment, proactive maintenance was essential. Our Motor Current Signature Analysis (MCSA) system installed at their site enables continuous condition monitoring and advanced fault detection.
The technology within the MCSA system was developed by a former NASA scientist and our partner Artesis Technology Systems, which utilizes patented algorithms for real-time monitoring and early fault detection, making it unique in the market. By integrating this technology, the station aimed to reduce unplanned outages and extend equipment lifespan.
Diagnosis and Insights
During routine monitoring, our MCSA system identified a pump imbalance issue, prompting a detailed further analysis. Cross-referenced SCADA readings confirmed elevated vibration levels of 4.54 mm/s rms on the Z-axis of the pump casing (suction side). This pointed to potential mechanical faults.
Further investigation by the MCSA software highlighted issues related to the rotor condition and component looseness. Upon closer inspection, their maintenance team discovered external debris denting the pump impeller, causing unbalanced rotation and excessive vibration. These findings underscored the value of real-time data and automated fault detection for proactive maintenance thanks to the MCSA technology.
Solution and Recommendation
Our client maintenance team addressed the identified issue by repairing the dented impeller and clearing the debris. This timely intervention resolved the imbalance, restored the pump’s operational balance, and averted significant downtime for the water pumping station.
The MCSA system fosters a culture of proactive maintenance for our client on-site team, allowing their facility to minimize operational risks and optimize their resources effectively.
