Pravilna izbira črpalke, nižji stroški za energijo
Gantar, Marjan, 1951-
Prispevek obravnava tri karakteristične primere črpališč iz Istarskih in Goriških vodovodov, v katerih so bile črpalke zamenjane oziroma rekonstruirane s ciljem zmanjšati stroške za energijo. Osnovne ...pomanjkljivosti teh črpališč so bile: delovanje pri nizkem izkoristku, pojav kavitacije, predimenzioniranost črpalke s stališča pretoka. Podanih je nekaj predlogov, kako se tem pomanjkljivostim lahko izognemo že v fazi projektiranja črpališč in izbire opreme.
