Modeling of the Supplying Process of Building Mixture by Using of Peristaltic Concrete Pump

Abstract

Presently constructors use peristaltic concrete pumps for wet shotcreting processes or for transferring the building mixes to the place of their deposit. Fitting the flexible-hose concrete pump with a hydraulic drive allows both making the range of its operating modes much broader and enhancing its reliability. Numerically simulated models of the building mixes feeding processes were developed to design a hydraulic drive to fit the general-service flexible-hose concrete pump and to calculate its basic parameters. Simulation of the building mixes feeding processes gave the characteristic curves of the concrete pump operating parameters, determined the time of ramping the concrete pump up to the steady running mode, and estimated the impact of the transferred mix density and viscosity to the maximal system pressure, supplied power and torque values.

Increasing the reliability of engineering buildings and strengths of use of new small-based equipment for concrete works

“…If there is a gradual loading of the hose in the working part of the pump casing with the rotating rotor rolls [13,14], the service life of the new machine exceeds the life of the hours of modern hose-type concrete pumps by 25%.…”
