Abstract:
A method for cleaning industrial lubricants used in industrial processes, the method comprising providing a centrifugal separator apparatus connected as a bypass or in-line filter in a lubricating or washing fluid tank, the apparatus including more than one centrifugal separator, each separator having a casing and a rotor rotatably mounted in the casing, an inlet and an outlet, with the inlets of the separators connected to an inlet manifold and the outlets of the separators connected to an outlet manifold, a centrifugal pump provided between the tank, and the inlet manifold, and a source of compressed air provided connected to the casings of the separators, some of the fluid from the tank being pumped by the centrifugal pump into the separators to cause the rotors to rotate and impinge the fluid on the casings at a rotational force in a range of between about 1000 g and about 2000 g and clean the fluid, the cleaned fluid being returned to the tank, a control panel monitoring the operation of the separators and controlling the pump and source of compressed air to maintain the rotational force of the separators within the range of about 1000 g to about 2000 g.
