Abstract: Long-distance water supply systems are important measures to improve the water resources distribution, and the water hammer protection devices such as air vessels are usually added in the project to ensure the safety and ...

Abstract: The maximum upsurge (MU) and the maximum air chamber pressure (MACP) are critical parameters for the design of air cushion surge chamber (ACSC) in hydropower stations. In this paper, the existence of the MU and the MACP ...

Abstract: This study investigated the water hammer pressure due to the sudden closure of the partially open valve experimentally and analytically. Because the partially open valve could produce local nonuniform flow, a supplementary ...

Abstract: The oil cavity shapes, which represent the spatial structures for storing lubricant in static and dynamic thrust bearings, and offset distances, defined as the horizontal distances between the load center and the bearing ...

Abstract: During the processing of heavy machine tools, due to the effect of eccentric load, the oil film thickness changes, which directly affects the lubrication performance of the bearing. Therefore, this study takes the tiltable ...

Abstract: This paper theoretically analyzed the design and operating parameters of a pipe-shaped air-cushion surge chamber (PS-ACSC). A mathematical model for a small load disturbance (SLD) in a hydropower plant containing the PS-ACSC ...
