Straight-tooth rotary pump with vortex hydrodiode

The paper presents a new technical solution for upgrading a straight-tooth rotary pump by replacing the traditional valve-type liquid distribution with a hydrodiode distribution. A vortex hydrodiode is proposed as an alternative distribution element. A comprehensive analysis of the influence of geometric parameters on the diode performance of a hydrodiode has been carried out. It is established that when optimizing the parameters of the hydrodiode, the diameter of the nozzle tube openings and their number are of priority importance. Based on numerical modeling, the optimal design option for a vortex hydrodiode with a maximum diode D = 1.618 has been identified. The results obtained can be used to design this type of hydrodiodes.
