Energy Characteristics of the Oil Vortex Chamber Supercharger

Very often, deposits with a great depth of occurrence are used irrationally due to pumping equipment’s absence or low efficiency. As the efficiency of classic pumps decreases, it becomes expedient to search for and use new pumping technologies based on jet technology. Research of oil vortex chamber superchargers can lead to advanced designs with high efficiency. The purpose of the paper is to determine the integral characteristics of oil pumping by vortex chamber pump and to determine the effect on the characteristics of dissolved gas and various overpressures in the suction channel. The study consisted of three stages: experimental adequacy confirmation of the proposed fluid flow mathematical models in the vortex chamber pump, simulation of pump characteristics when it pumps oil with dissolved gas, and obtaining pump characteristics. It was found that the oil vortex chamber pump efficiency exceeds the efficiency of the serial industrial jet pump of the direct-flow type by 2.5 times, and the pump’s overall size is reduced by more than 3 times. As the suction pressure increases, there is a linear decrease in the relative useful pressure at the outlet of the pump in the absence of static pressure at the outlet.
