  • Filtration Of Liquid (AREA)

Abstract

Filters are cleaned by back-washing, using a pump (2) delivering oil to the filter inlet (4a), oil being returned from the filter discharge (4b) to the storage tank (1). During back-washing, the flow from the filter inlet (4a) is routed to a valve (6) which opens at a high pressure and closes at a lower pressure, it being closed at the start of the back-wash process. While the valve is closed, the pump (2) delivers oil to the pressure maintaining vessel (5). Opening the valve significantly reduces the pressure at the filter inlet, causing a high pressure, high velocity flow impulse through the filter. Inlet and discharge connections are connected via change-over valve to the pump and storage tank, so that during back-washing the pump is connected to the filter discharge, and the filter inlet is connected via the valve to the contaminated oil storage tank (7), and the pressure maintaining vessel is connected into the pipe between the filter discharge and the valve.
