| Summary: | Peristaltic pump units are used in medicine, for pumping blood and its components, and in mechanical engineering for working with aggressive media. The only element in this pump that comes into contact with the working medium is the hose. Such hose characteristics as chemical resistance and wear resistance directly affect the operating life of the entire pump. The purpose of this work is to increase the service life of the peristaltic pump unit by developing a hose with improved wear resistance (WRH). During the study, the following problems were solved: the process of obtaining 3 different polymer materials for the manufacture of WRHs was selected, the technology for manufacturing WRHs was selected, and the mechanical properties of the resulting structure were studied. As a result, it was determined that all selected materials and design were workable, however, a sample made of ethylene-propylene rubber (EPDM) and polypropylene (PP) with a mass percentage of 75/25 (75% EPDM and 25 % PP) material, has the greatest wear resistance in comparison with other samples, which makes it optimal for making a hose. |
