In order to clarify the non-constant flow characteristics of impeller and bulb body submersible tubular electric pump device, entire rate conduit device is numerically calculated using numerical simulation method, focusing on analysis field guide vane time–frequency variation law pressure pulsation, results physical model testing confirm validity simulation. The findings demonstrate that a most...

Pulsed energization of electrostatic precipitator (ESP) may represent one of the most promising solutions to comply with strict environmental regulation in case of high resistivity dust. Performs a parametric cost comparison between conventional and pulsed ESP with reference to four main industrial areas: electric power generation, cement manufacturing, iron and steel production, glass industry...

Abstract This study introduces a comprehensive and cost-effective approach to diagnose treat the asphaltenes precipitation problems in different downhole conditions. The proposed has been successfully applied two oil wells (Well-I, Well-II) located Western Desert of Egypt. produce moderate high gravity with low content using Electrical Submersible Pumps (ESP). In such operating conditions, soli...

BACKGROUND: The study object is a high-speed drainage submersible electric pump, aimed to water polluted sea and fresh bailing out of drowned rooms shipbuilding industry facilities.
 AIMS: To obtain dependencies pump cavitation properties on relative diameter an impeller inlet at the high flow rate modes, determine kind head-capacity energy for various geometrical ratios in operational ran...

Abstract In view of the problem that actual performance axial-flow pump is less than theoretical design value, Taking with a designed flow rate 350L/s as research object. The relationship between impeller head and outlet installation angle was studied. influence different blade angles on external characteristics analyzed. Through analysis corresponding to angles, shaft oil verified, basis for s...
