Opis:: Angular momentum pumps are very often applied onboard ships. These pumps are used in cooling circuits of medium and high power engines, power plant boilers and in bilge, ballast and fire installations. Very extensive use of angular momentum pumps on board is connected with their numerous advantages. During operation the wear of marine hull, the rotor and shaft seals take place. The research attempts to increase the service life of shafts. The article presents the research results referring to the analysis of the influence of finish treatment (lathing, grinding and burnishing) on the corrosion properties of steel applied to marine pump shafts. The research was performed on a roller of 40 mm in diameter made of X5CrNi18-10 (AISI 304 L) stainless steel. The lathing process was carried out by means of a WNMG WF 080408 Sandvik Coromant cutting tool with replaceable inserts. The grinding process was performed by grinding attachment for lathes. The 1 - 80x10x32 - 99C 80-N V grinding wheel was used for the process. The process of burnishing was done by SRMD burnisher by Yamato. In addition, the influence of the burnisher passes number on the corrosion properties was determined. The paper will present the results of electrochemical impedance spectroscopy research. To conduct the survey the Atlas 0531 EU and IA potentiostat was used. Determination of the corrosion process parameters was performed computer programs: AtlasLab 2.0 and EIS Spectrum Analyzer.

Opis:: Angular momentum pumps are frequently applied on board ships. As the pumps are working in hard conditions they are made from materials resistant to cavitation wear and electrochemical corrosion. The most popular damage of pump shaft is neck wear in place where seals are mounted. Burnishing, as modern finish plastic tooling method, makes it possible to get high technological quality of elements. The proposed process of burnishing shaft pins is designed to increase the service life of marine seawater pump shaft installations, which should enhance the economic effect. Thanks to its numerous advantages burnishing was proposed to angular momentum pumps shafts tooling instead of finish machining (finish turning, grinding, lapping). The goal was to estimate optimal burnishing parameters which enable receiving biggest strengthening and lowest roughness factor of angular momentum pumps shafts. The tool used was one-roll burnishing tool SRMD type produced by Yamato. The aim of this study was to determine the internat stresses occurring in the subsurface layer after machining carried out, and after burnishing the surface of marine pump shaft pins made of X5CrNH810 stainless steel.

Opis:: Angular momentum pumps are applied very often on ships. Because the pumps are working in hard conditions they are made from cavitation wear proof and electrochemical corrosion proof materials. The most popular damage of pump shaft is neck wear in place where seals are mounted. Burnishing as modern finish plastic tooling method makes possible getting high technological quality of elements. Because of many burnishing advantages it was proposed to shafts angular momentum pumps working instead of finish machining (finish turning, grinding, lapping). The goal was to estimate optimal burnishing parameters, which enable to receive biggest strengthening, and lowest roughness factor of angular momentum pumps shafts. The shaft necks are made from stainless steel X5CrNi1810. The tool, one - roller burnishing tool SRMD type produced by Yamato. Its axis is parallel to working shaft axis. During working technological parameters like force, velocity and feed were changed.
Na statkach bardzo często wykorzystuje się pompy krętne. Ze względu na trudne warunki ich pracy do budowy tego rodzaju pomp stosuje się materiały odporne na zużycie kawitacyjne oraz korozję elektrochemiczną wywołaną przez wodę morską. W przypadku wałów pomp najczęstszą niesprawnością jest zużycie czopów (korozyjne, cierne i zmęczenie stykowe) w miejscu montażu uszczelnień (dławic). Obróbka nagniataniem jako nowoczesna metoda wykańczająca obróbki plastycznej umożliwia uzyskanie elementów maszyn o odpowiedniej jakości technologicznej. W związku z licznymi korzyściami stosowania obróbki nagniataniem proponuje się jej zastosowanie w zamian za wykańczającą obróbkę skrawaniem (toczenie wykańczające, szlifowanie, polerowanie) do wałów okrętowych pomp krętnych. Celem pracy było wyznaczenie optymalnych parametrów nagniatania dla uzyskania największego stopienia względnego umocnienia warstwy wierzchniej i zmniejszenia chropowatości powierzchni czopów wałów okrętowych pomp krętnych wykonanych ze stali nierdzewnej X5CrNi1810. Proces nagniatania przeprowadzono nagniatakiem jednorolkowym SRMD firmy Yamato, który charakteryzuje się równoległością osi części roboczej do osi obrabianego czopu. Podczas nagniatania zastosowano zróżnicowane parametry procesu technologicznego takie jak: siła nagniatania, prędkość nagniatania oraz posuw.
