    Technical Solution for Abnormally Reduced Rotational Speed in D-Type Horizontal Multistage Centrifugal Pumps

    Technical Solution for Abnormally Reduced Rotational Speed in D-Type Horizontal Multistage Centrifugal Pumps

    The D-type horizontal multistage centrifugal pump, as a core fluid-handling equipment in industries such as petrochemicals, water conservancy, and power generation, has operational stability that directly affects production continuity and system energy efficiency. The rated speed (1450 rpm/2900 rpm) is the fundamental basis for ensuring that key parameters such as head and flow rate meet design specifications; once the speed falls below the design threshold, not only does pumping efficiency decline markedly and energy consumption rise, but cascading failures such as cavitation and accelerated component wear may also occur, potentially leading to production-line shutdowns and safety risks. In current industrial settings, troubleshooting speed anomalies often lacks standardized logic due to the complex interplay among multiple systems, resulting in biased diagnostics and delayed maintenance. To address this, this paper draws on national and industry standards—including GB/T 12350-2008, API 610, and ANSI/ASME B73.1—to develop a four-dimensional fault-diagnosis framework spanning electrical, power, fluid, and mechanical domains. This framework is complemented by tiered solutions for emergency response, planned maintenance, and preventive upkeep, along with clearly defined, end-to-end safe-operation procedures. The result is a problem-solving guide that combines scientific rigor with practical applicability, helping engineering personnel rapidly pinpoint fault origins, reduce maintenance costs, and ensure long-term, stable equipment operation.
