  • Method and arrangement to watch over separated sediment, which is thrown out through nozzles of a centrifugal separator
    Patent number: 4410318
    Abstract: At a centrifugal separator (21), where separated sediment is thrown out in jets (26) from the rotor (22) of the separator through a determined number of nozzles (1, 2, 3) a sensing means (28) is arranged to be influenced by the respective jet and give off a signal (U), which is a measure of a quantity, e.g. the flow, of the medium of the jet, which signals (U) are given off to an apparatus (38), which is arranged to record the signals (U) and in its turn give off a signal (39, 39A, 39B, 39C), if said quantity of the medium in one or more jets is changed, e.g. if the flow through a nozzle ceases by the nozzle having been blocked or if the flow through a nozzle has increased by the nozzle having been eroded.
