This paper offers a test method for rheological behavior of mortars with different mobility and different composition, which are used for execution of construction work. This method is based on investigation of the interaction between the valve ball and the mortar under study and allows quick defining of experimental variables for any composition of building mortars. Certain rheological behavior will permit to calculate the design parameters of machines for specific conditions of work performance – mixing (pre-operation), pressure generation, pumping to the work site, workpiece surfacing.
The supposition of productivity gain of finishing work using plastering machines has been considered in the article. The work of constituent parts of plastering machines has been studied. The working parameters of the plastering machine has also been calculated. There has been evolved the planning of a three-factor experiment of the second order with the aim of determining the working power, consumed by the mortar pump.
The paper is dedicated to the creation of a differential mortar pump with electromagnetic action for pumping finishingmaterial, which is not sensitive to electric energy gaps, and which is at the same time convenient, easy to use, reliable andeconomical in operation. The paper presents the mathematical model of the working process dynamics of a differentialmortar pump with electromagnetic action, which will allow to study common patterns of pumping processes in the pump inthe whole, to solve general problems on their calculation and design, to set and solve problems of reliability control,connected with high-frequency pressure oscillations, the problems of structural optimization and optimal design of all itselements. The control system of a pumping unit with vector controlled asynchronous electric drive is proposed on the basis ofthe concept of inverse dynamics problems in combination with the minimization of local functionality of instantaneousenergy magnitudes, which ensures high-quality pressure regulation under the conditions of parametric perturbations activityand has acceptable energy indices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
