Effect of blade coating on a centrifugal pump operation under sediment-laden water flow
Yong Wang, Zilong Zhang, Jie Chen, Houlin Liu, Xiang Zhang, Marko Hočevar
Izvirni znanstveni članek
Oznake: blade coating;vibration;pressure fluctuation;sediment-laden flow;centrifugal pump;
Applying a high strength coating on a blade's surface could significantly prolong the service life of a centrifugal pump under sediment-laden water flow because of its protection. To explore the effect of blade coating, the characteristics of energy, vibration and pressure fluctuation of a centrifug ...

Effect of coating thickness on a solid-liquid two-phase flow centrifugal pump under water medium
Kaikai Luo, Yong Wang, Houlin Liu, Matevž Dular, Jie Chen, Zilong Zhang
Izvirni znanstveni članek
Oznake: coating thickness;solid-liquid two-phase flow pumps;numerical simulation;pressure fluctuation;radial force;
Spraying a coating on the surface of wet parts of a solid-liquid two-phase flow centrifugal pump could effectively increase its service life. To research the effect of coating thickness on the performance of the pump, a solid-liquid two-phase flow pump with a speed of ns = 81.5 was chosen, and polyu ...

Optimization of a self-excited pulsed air-water jet nozzle based on the response surface methodology
Yong Wang, Xiaolin Wang, Zilong Zhang, Yu Li, Houlin Liu, Xiang Zhang, Marko Hočevar
Izvirni znanstveni članek
Oznake: multiphase flow;impact force;cleaning performance;optimization;pulsed jet;
A self-excited pulsed air-water jet (SEPAWJ) offers many advantages over other jets and has a large number of practical and industrial applications. In order to take better advantage of the SEPAWJ, response surface methodology (RSM) models were established with the experimental impact force characte ...

Effect of vibration and noise measuring points distribution on the sensitivity of pump cavitation diagnosis
Runze Zhou, Hui Chen, Liang Dong, Houlin Liu, Zeyu Chen, Yuhang Zhang, Zhiming Cheng
Izvirni znanstveni članek
Oznake: cavitation;centrifugal pumps;vibration;noise;measuring points;spectral analysis;
Cavitation is an essential factor in the deterioration of the hydraulic performance of centrifugal pumps. The study of cavitation fault diagnosis can help avoid or reduce the damage it causes. The vibration and noise analysis method can predict the incipient cavitation more accurately. In order to i ...
