Abstract:The article deals with the issues of ensuring the safe dosing of small volumes of chemical reagents with positive displacement pumps. The results of simulation of hydrodynamic processes in valve assemblies are presented. Studies have shown the low efficiency of the reagent supply process using ball and poppet valves. The use of hydraulic diaphragm and vortex diodes is proposed. Based on amathematical modeling, the design features of hydrodiodes and the parameters of their effective operation are substantiated,… Show more
