Performance of automotive concrete pumps

The features of determining the performance of a concrete pump at various stages of liquid pumping are considered. When calculating the performance characteristics, the approximating functions for piston pumps previously proposed by the authors are used. The parameters of operation of concrete pumps in the nominal mode are determined by the performance diagrams, as well as for stationary concrete pumps. The dynamics of changes in hydraulic characteristics during the operation of a pump installed in a concrete pump is considered. A diagram of the performance of a reciprocating concrete pump in the high-performance and low-pressure mode is obtained. The results of calculating the performance of a piston concrete pump with a change in the frequency of movement of the piston are presented.
