EXPERIMENTAL DETERMINATION OF THE INFLUENCE OF PRESSURE VOLUME ON THE SLIP OF THE RECIPROCATING DOSAGE PUMPS

Starting from the assumption that the accuracy of discharge of a reciprocating dosage pump, for a certain fluid, depends on the kinematic and hydrodynamic properties of the pump, the slip has been experimentally determined by varying the pressure intensity in the pump-pipeline. A device for experimental testing of the reciprocating dosage pump operation with a system for measuring and processing the signals has been developed. A total of 40 measurements were performed with various intensities of operating pressure and different pump piston stroke lengths. The discharge volume, the piston stroke length and pressures at relevant points of the pump-pipeline system have been measured. The results of experimental slip determination have been presented in the form of diagrams and tables and they confirm the authors’ assumptions regarding the influence of pressure intensity on the slip of the reciprocating dosage pumps.
