Oznake: WE-type slip hangers;suspension load;slip hanger bite depth;finite element simulation;casing;
There is great difficulty in controlling the setting load of the large-size slip casing hanger in the Northwest Oilfield in China, and a reasonable setting load is of great significance. This paper studied the relationship between slip hanger bite depth and suspension load in the % 273 mm WE-type sl ...

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 ...

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 ...

An efficient and unbiased stereological method was applied to estimate the white matter volume, the total volume, total length and mean diameter of the myelinated fibers in the white matter and the total volume of the myelin sheaths in the white matter of rat brain. The white matter volume was obtai ...

The mild reaction of the preorganized silsesquioxane precursor with Mn(II) acetate under ambient conditions results in a mixed-valent {MnII 6MnIII4} nanocage (SD/Mn10) which is protected by both acyclic trimer [Si3] and cyclic tetramer [Si4]. Serendipitous capture of atmospheric CO2 as a μ5-carbonat ...
