Erosive wear model of slurry pump impeller / Veselin Batalovic in Transactions of the ASME . Journal of tribology, Vol. 132 N° 2 (Avril 2010) 

Public ISBD [article]  in Transactions of the ASME . Journal of tribology > Vol. 132 N° 2 (Avril 2010) . - 05 p. Titre : Erosive wear model of slurry pump impeller Type de document : texte imprimé Auteurs : Veselin Batalovic, Auteur Année de publication : 2011 Article en page(s) : 05 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Impellers  Monte  Carlo  methods  Pumps  Slurries  Wear  resistance Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : Erosion wear is a serious problem that constantly accompanies the operation of the system for hydraulic transportation of solid materials. The consequences are the loss of material (steel), loss of work element's working capacity, great operational expenses, etc. The choice of new materials for working elements, improvements in construction, and optimization of the slurry flow are all various ways of softening the consequences of erosion wear that reflects on the working life of the hydraulic transportation pump's elements. Data, which would be used for acquiring the above mentioned goals, are mainly acquired through testing in laboratory or semi industrial conditions. It has been proved that numerous influential and time effected values, complex and long term research, etc., make this job an expensive one, and the results are often solely applicable to specific operating conditions. To resolve this problem, the author suggests a combined approach: shorthand experimental researches and mathematical modeling of erosion wear. The suggested model, used for defining the mass loss of the working element affected by solid particles in the slurry, offers the possibility of introducing a greater number of influential values, some of which have a coincidental character. Through the realization of this model, wear intensity data is acquired, which are practically noncoincidental values with a great degree of reliability, and which greatly coincide with the results acquired through measurements conducted on the test facility.

Slurry pump impeller wear / Veselin Batalovic in Transactions of the ASME . Journal of tribology, Vol. 132 N° 3 (Juillet 2010) 

Public ISBD [article]  in Transactions of the ASME . Journal of tribology > Vol. 132 N° 3 (Juillet 2010) . - 05 p. Titre : Slurry pump impeller wear : testing Type de document : texte imprimé Auteurs : Veselin Batalovic, Auteur Année de publication : 2011 Article en page(s) : 05 p. Note générale : Tribology Langues : Anglais (eng) Mots-clés : Impellers  Wear  Wear  testing Index. décimale : 621.5 Energie pneumatique. Machinerie et outils. Réfrigération Résumé : Erosion wear is a process that accompanies the facility for hydraulic transportation of solids. Since the pump is one of the vital parts of this facility, the working life of the pump is conditioned by the amount of wear. The working life can be realized only if the parameters chosen, for the pump elements, slurry, and transport conditions, will provide economic transport with minimal wear. Testing is the most reliable method for acquiring valid data. The two issues that need to be solved while planning the testing process are the choice of valid similarity criteria (test-industrial facility) and data selection. After the theoretical analyses, technically acceptable similarity criteria are obtained. A group of data needs to be defined through the experiment.
