Annotation:
The article provides general information about dosing units and pumps, about their areas of application. The results of fluid flow modeling in the valve assembly are described. It is revealed that pumps with hydraulic diodes can be used to eliminate pulsations. The results of fluid flow numerical simulation by the finite elements method in the ANSYS software package for various designs of hydraulic diodes are presented. Since it was theoretically impossible to determine all parameters and characteristics of the pump operation mode, a laboratory unit was developed to study the process of dosing reagents and oil markers, the use of which made it possible to conduct field studies. The article contains a diagram and a photograph of the developed unit, its description and operational principle. This unit allows determining the minimum stable flow of the dosing pump for a specific design of valve assemblies at the given operating parameters.
