Lubrication control system

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.

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.
