Vertical differential grout pump experimental studies methods validation

Abstract

The article is devoted to creation and substantiation of experimental research method of vertical differential grout pumpwith flowing piston mark РН 2-4, developed by researchers at Poltava National Technical Yuri Kondratyuk University.Experiments type has been substantiated, variation intervals of the studied parameters values have been determined, thepreparation of the experimental sample of the grout pump for research has been described, an experimental installation for researchhas been designed, the measuring means have been selected, the conditions for performing the experiments have beendetermined. This technique enables to find the rational values for the following parameters of the solution pump when workingwith plaster solutions of different displacement: working body frequency movement, diameter, mass and height of liftingover the valve, the hole diameter in the valve sockets.
