Automatic Optimization of Vertical Long-shaft Fire Pump Overload Based on Particle Swarm Optimization Algorithm

Abstract

As a typical large-flow high-head pump, the vertical long-axis fire pumps have the advantages of rapid startup, superior structure, and strong applicability in multiple occasions. In order to shorten the non-overload optimization cycle, CFturbo, ICEM and CFX are integrated by writing batch processing commands to achieve automatic multi-load and no-load optimization of vertical long-axis fire pumps based on Isight’s multi-disciplinary optimization platform. With the objective of achieving the non-overload characteristics of vertical long-axis fire pumps, the optimal Latin hypercube design is used to spatially sample the design variables of the impeller. After sampling, the particle swarm optimization (PSO) algorithm is used to optimize the design. The results show that, vertical long-axis fire pumps achieve non-overload characteristics within 1.5Q 0 after optimization, while the head and efficiency at the rated operating point are almost unchanged.

Experimental research on pressure pulsation and cavitation characteristics of centrifugal fire pump

“…Yang et al 11 applied a low specific speed centrifugal pump to a fire truck and fixed the blade outlet angle to guarantee no overload performance while adding an induced wheel to improve the cavitation performance. Zhang et al 12 established an automatic optimization method for the overload problem of the vertical long-shaft fire pump based on particle swarm optimization. Cai et al 13,14 developed a three-stage centrifugal forest fire pump with a wide high-efficiency zone, and Paluch et al 15 proposed a single-stage centrifugal pump impeller design method for fire trucks.…”

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

“…To improve the efficiency of centrifugal pumps, Kocaaslan et al (2016) optimized geometric parameters, such as the impeller inlet and outlet diameters, blade inlet and outlet angles, blade wrap angle, blade thickness, blade inlet, and outlet width. Zhang et al (2021) used particle swarm optimization algorithms to optimize the design of a vertical longshaft fire pump to achieve an overload-free design. Paluch and Noga (2020) proposed a single-stage centrifugal pump impeller design for fire engines.…”

Effects of Turbulence Models on Flow Characteristics of a Vertical Fire Pump

“…Therefore, they are frequently employed for projects such as offshore platforms, urban drainage and storm water management, feedwater supply, and a variety of other applications. This increased desire for vertical long-axis fire pumps also results in higher expectations for their performance (Hu et al 2012;Yu 2014;Zhang et al 2021).…”

“…It must be noted that the vertical fire pump under investigation was previously optimized by Zhang et al (2021) to stabilize the power performance curve. The optimized model geometry was re-meshed and the setup was simulated independently with four different turbulence models, while maintaining all the other parameters constant.…”
