PRIMJENA PUMPI U BRODSKIM SUSTAVIMA

U uvodu ovoga rada dane su osnovne uvodne rečenice, koje ukazuju na osnovnu tematiku ovoga rada i daju osnovne informacije o pumpama i njezinom razvoju kroz povijest. Prvo poglavlje daje podjelu pumpi, opis pojedinih tipova pumpi koje se primjenjuju u brodskim sustavima te su objašnjene vrste pogona pumpi Drugo poglavlje prikazuje te opisuje opće karakteristike pumpe i cjevovoda, izračun gubitaka, učina i stupnjeve djelovanja te je objašnjena NPSH, tj. neto pozitivna visina posisavanja. Treće poglavlje donosi i objašnjava pojedine postupke odabira pumpe, zajednički rad više pumpi u serijskom i paralelnom spoju te svojstva tekućina. U zadnjem dijelu su objašnjeni problemi koji prate pumpe u brodskim sustavima te njihova kontrola i zaštita.In the introduction to this work are given a basic introductory sentences, which indicate the basic theme of this work and give basic information about pumps and its development throughout history. The first chapter gives the distribution of the pumps, the description of the individual types of pumps used in the ship´s systems and there are explained the types of drives of the pumps. The second chapter shows and describes the General characteristics of pumps and piping, the calculation of losses, power and output of action and there is explained the NPSH, net positive suction head. The third chapter brings and explains the procedures for selection of individual pumps, more pumps working together in the serial and parallel and the properties of the liquid. The last part explains the problems that accompany the pump into the ship’s systems and their controls and protection
