Devising a method for ensuring the reliability of fire centrifugal pumps while reducing their weight and dimension characteristics by optimizing their structural elements

Hydraulic Optimization and Experimental Measurement of Low Specific Speed Centrifugal Fire Pump

“…With the development of fire-fighting systems, centrifugal pumps are increasingly being used in fire-fighting. To obtain the optimum mass dimensional parameters for centrifugal fire pumps, Vasiljeva et al (2020) developed an optimized mathematical model that enables centrifugal pumps for fire-fighting to be designed in such a way that the weight of the pump is minimized while ensuring high reliability. To attain centrifugal fire pumps with excellent performance, splitter blades (Shi et al 2009;Yuan and Yuan 2017;Rosa Emerick 2020;Namazizadeh et al 2020;Chabannes et al 2021;Adu et al 2021) were used to change the internal flow characteristics of low-specific-speed centrifugal fire pumps, and Yang et al (2017) used an increased flow rate design method.…”
