Korobko B. Research of working process of the mortar pump with the combine driving law of stream flow plunger

The Object of research: The vertical differential mortar pump with the combine driving law of the stream flow plunger, intended for the finishing work caring out. The purpose of research: Improving of the efficiency of the mortar pumps working process on the basis by the interaction conditions research their end-effectors with pumpable material, and also by elaboration the combine driving law of the pump stream flow plunger. Methods of research: Are grounded on a system of the classical mechanics laws, and mechanics of a fluid and gas. The means of the comparative and many factors analysis, methods of logical generalization, physical and mathematical modelling were used for handling the results of research. Equipment: Gears of pressure measurement; the tensometrical equipment; a gear for record of fast flow processes parameters; computer equipment. Theoretical and practical results: The scientific-justifies account method's of the factor the working chamber filling by building solution at a sucking andthe volumetric efficiencies of mortar pump are elaborated. New definition methods of the parameters an elastic and rheological property's of building solution are elaborated. The quantitative indexes of this property's are obtained. The differential mortar pump with a cam drive stream flow plunger, which has to improved technological parameter is created. The account methods of its design index's is elaborated. Novelty: New regularities of interaction by mortar pump end-effectors with a pumpable material, which take into account elastic and rheological property's of building solutions are established. An elastic and rheological property's of the pumpable material, which complicate conditions of the mortar pump operation are theoretically justified. The parameters of the most favorable mode of mortar pump operations with reduction the pulsation of feeding, dynamic loads, lowering of levels by volumetric losses and hydraulic resistance are defined. Level of application: The results are introduced into elaboration of mortar pump, which successfully has passed tests by the construction firm "Ukrgasprombud" and recommended for the further issue. Field of applications: Scientific establishments, industrial and building enterprises, educational institutions connected with elaboration, manufacture and maintenance of machines for transportation the building solutions till a pipelines and their mechanical drawing on the job surfaces.
