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 ...

Forced vibration of time-varying elevator traction system
Jie Sun, Peng Xu, MingLi Chen, Jianghong Xue
Izvirni znanstveni članek
Oznake: elevator traction system;vibration;time-varying;dynamics;numerical analysis;
This paper proposes a theoretical model for the forced vibration of time-varying elevator traction systems caused by eccentric excitation of the traction machine. Based on the Hamilton principle and a variational principle with variable boundaries, the equations of motion and the complex boundary co ...
