Lubrication control system
First Claim
1. A lubrication control system for intermittent dosing of lubricant to one or more lubrication stations in a centrifugal separator, said lubrication control system comprising:
- a lubricant supply arrangement for supplying lubricant to at least one of the one or more lubrication stations;
at least one pump supplying intermittent pulsed volumes of lubricant from the lubricant supply arrangement to at least one lubricant pulse monitoring device, said at least one lubricant pulse monitoring device comprising;
an elastic chamber to receive said pulsed volumes of lubricant from the at least one pump;
an outlet export valve at an outlet from the elastic chamber, said outlet export valve closing when a pulsed volume is delivered to the elastic chamber and opening to deliver the lubricant to the one or more lubrication stations; and
a pressure transmitter measuring the pressure in said elastic chamber at least when a pulsed volume is received in the elastic chamber; and
a control computer, said control computer;
regulating the at least one pump controlling the pulses;
closing the outlet export valve when a pulsed volume is delivered to the elastic chamber;
measuring a pressure in the chamber, the measured pressure in the chamber corresponding to an amount of lubricant in the chamber; and
if the measured pressure in the chamber corresponds to a required volume of lubricant, opening the outlet export valve for deliverance of lubricant to the one or more lubrication stations.

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

16. A method for intermittent dosing of lubricant to one or more lubrication stations in a centrifugal separator, comprising the steps of:
-
pumping intermittent pulsed volumes of lubricant to an elastic chamber; measuring the pressure in the elastic chamber when the elastic chamber has received a pulsed volume, the measured pressure in the elastic chamber corresponding to an amount of lubricant in the chamber; determining if the measured pressure corresponds to a required volume of lubricant; opening an outlet export valve at an outlet of said elastic chamber and emptying the elastic chamber when the measured pressure corresponds to the required volume of lubricant; and closing said outlet export valve to receive a next pulsed volume of lubricant to the elastic chamber. - View Dependent Claims (17, 18)

19. A lubrication control system for intermittent dosing of lubricant to one or more lubrication stations, comprising:
-
a lubricant reservoir supplying lubricant to one or more lubrication stations; a pump supplying intermittent pulsed volumes of lubricant from the reservoir; a lubricant pulse monitoring device, the lubricant pulse monitoring device comprising; a housing having an inlet in fluid communication with the pump and an outlet; a passage extending between the inlet and outlet; a variable volume chamber receiving said pulsed volumes of lubricant from the pump, the variable volume chamber in fluid communication with the passage; and a pressure transmitter measuring the pressure in the variable volume chamber; an outlet export valve at the outlet of the lubricant pulse monitoring device, the outlet export valve opening to deliver the lubricant to the one or more lubrication stations; and a control computer, said control computer opening the outlet export valve for deliverance of lubricant to the one or more lubrication stations when pressure in the variable volume chamber corresponds to a required volume of lubricant. - View Dependent Claims (20)
