Abstract

Lubrication control system (1) for intermittent dosing of lubricant to one or more lubrication stations in a centrifugal separator comprising a lubricant supply arrangement (2) for supplying lubricant to at least one lubrication station. At least one pump (3) is supplying intermittent pulsed volumes of lubricant from the lubricant supply arrangement (2) to at least one lubricant pulse monitoring device (6) comprising an elastic chamber (9) to receive said pulsed volumes of lubricant from the pump (3), an outlet export valve (11) at an outlet (10) from the elastic chamber (9) closing when a pulsed volume is delivered to the elastic chamber (9) and opening to deliver the lubricant to the lubrication station, and a pressure transmitter (14) measuring the pressure in said elastic chamber (9) at least when a pulsed volume is received in the elastic chamber (9). A control computer (5) regulating the pump (3) controlling the pulses, closing the outlet export valve (11) when a pulsed volume is delivered to the elastic chamber (9), controlling the measured pressure in the elastic chamber (9) and opening the outlet export valve for deliverance of lubricant to the lubrication station. Also a corresponding method comprises pumping intermittent pulsed volumes of lubricant to an elastic chamber (9), measuring the pressure in the elastic chamber (9) when the elastic chamber (9) has received a pulsed volume, controlling if the pressure corresponds to a required volume of lubricant, opening an outlet export valve (11) at an outlet (10) of said elastic chamber (9) and emptying the elastic chamber (9) and closing said outlet export valve (11) to receive next pulsed volume of lubricant to the elastic chamber (9).
