“…However, the reliability of pumps are difficult to define and predict. Although there are several researches about predicting pump failures [1], [2], the pump reliability curve proposed by Barringer [3]- [5], which uses the Mean Time Between Failure (MTBF) as the measurement of pump reliability, are widely used due to its simplicity. Usually a pump is designed for a certain flow rate, which is called Best Efficiency Point (BEP) flow rate.…”

Parallel pump systems are widely used in industries. However, pumps are often operating under off-design conditions due to many reasons, which reduces the efficiency and reliability of the pumps. This paper aims at reducing the power consumption of parallel pump systems and improving the reliability of pumps by improving the operation points of pumps. To achieve this goal, a combination of selecting the proper number of pumps to put into operation and their speed is needed. Also, a control valve is adopted to further improve the operation points. The optimization model is built for a parallel pump system. Particle swarm optimization algorithm is used to solve the problem. Experimental verification shows that the proposed method improves the reliability and can also reduce power consumption for some cases compared to conventional PID speed regulation method. But for cases with large flow, extra power might be needed because the control valve introduces extra flow resistance in order to improve the operation point. The proposed method can be easily extended to applications based on their requirements on reliability.

PurposeThis paper aims to examine the reliability of a cooling seawater pumping station which pumps seawater to refineries and petrochemical plants in Kuwait mainly for cooling purposes. Owing to the harsh operating climate and the lack of other alternative sources of water, high reliability of the pumping system is crucially important.Design/methodology/approachThe reliability of a system can be considered from different views. The one taken in this study is to measure the reliability of the cooling seawater arriving to the consumer at the required pressure and flow rate while observing the operational constraints on the system. A reliability model has been developed and applied to the actual data from the pumping station.FindingsThe preliminary results indicate that the model could be a useful tool to assess the current condition of the system and to find ways of improving system reliability and availability.Originality/valueThe paper provides information of value to all concerned with relibility management.
