ABSTRACT:
Apparatus is described for use in an industrial plant that contain machines (14) having oil reservoirs (12), which facilitates cleaning of the oil. The apparatus includes a stand (20) and equipment mounted on the stand, including input and output hoses (36,38) whose ends can be dropped into a machine oil reservoir. The equipment on the stand also includes a centrifuge (24), pump (26), valve (34), and porous filter device (40). In a first mode of operation, the pump draws oil from the reservoir to flow through the input hose into the centrifuge, and then to the output hose to flow back to the reservoir. The valve can be switched to a second mode wherein fluid from the input hose is directed through the pump to the porous filter device, for final cleaning of the oil before returning it to the reservoir. The stand has wheels to enable it to roll to another machine and clean its oil.
