Justification of parametric and dimensional series of magnetic peristaltic pump units

Efficient transportation of highly concentrated mixtures by soil pumps is difficult due to the existing non-linear relationship between efficiency and solids concentration. This necessitates the use of new design and technological solutions — magnetic pumping units. In them, the role of the drive is performed by the working chamber-channel. It is made of a magnetically active elastomer and implements the principle of peristaltic transportation of the hydraulic mixture under the influence of a magnetic activator. Taking into account the specifics of the operations performed for backfilling the goaf, it is necessary to conduct studies of the energy parameters of the equipment. The selection of equipment should be carried out not only from the condition of ensuring the efficiency of the technological process of backfilling the mined-out space, while observing the principle of equipment compactness. The fulfillment of the last condition implies the use of equipment of the smallest permissible, in terms of performance, power. A technique for developing a parametric and standard size range of the equipment being created is presented. The performance of the pumping unit and power consumption are taken as the main parameters of the equipment. The range of values of the preferred nominal power of the section of the magnetic activator of the pump unit obtained as a result of the calculations is recommended for use in the development of design documentation for the creation of mobile stowing complexes.
