Amaphampu e-DL kanye ne-DLR awela esigabeni samaphampu e-centrifugal amile mpo eyodwa asetshenziselwa ukuthutha amanzi acwebile angenazo izinhlayiya eziqinile noma olunye uketshezi olunezici ezifanayo zomzimba namakhemikhali njengamanzi acwebile.Isebenza kakhulu ekuhlinzekweni kwamanzi ezindaweni eziphakeme kanye nokuhlinzeka ngamanzi kanye nokukhipha amanzi ezimbonini nasezimayini.Ububanzi bokugeleza koketshezi oluthuthwayo ngu-4.9~300m³/h, ibanga lokuphakamisa ikhanda elingu-22~239m, ububanzi bamandla ahlobene 1.5~200kW, kanye nobubanzi bebanga elingu-40~200mm.
Amaphampu ochungechunge lwe-DL kanye ne-DLR ayasebenza ekuhlinzekeni kwamanzi ezimbonini nasemadolobheni kanye nokukhipha amanzi, ukucindezela kanye nokunikezwa kwamanzi okulawula ukuphakama nokushisa umlilo, ukuhlinzekwa kwamanzi amabanga amade, ukucindezela kokujikeleza kwamanzi abandayo nashisayo ukushisa, igumbi lokugezela kanye ne-boiler, ukuhlinzekwa kwamanzi. yesistimu yesiqandisi se-air-conditioning, okokufakwa kwemishini nokunye.Izinga lokushisa eliphakathi nendawo lokusebenza lohlobo lwe-DL akumele lidlule ku-80C kuyilapho lelo le-DLR lingeqi ku-120℃.
