| Maintenance

• The machine is mainly composed of filtering bed, oil pump and Coarse filter components
• Filtering bed is operated continuously, by pressure, the dirty oil is sucked into filtering groups which filter to the side. The groups are made up of a set of alternately sorted filter plates, filter frames, and facility which has a Manual Screw Press Device and press plate. There is a lug on the side of filter plate and filter frame to support the layer board of the machine framework, and There are filtering media, such as industrial filtering paper or filtering cloth, installed between the filter plate and filter frame that will be fixed to form a single filtering chamber between stationary Thrust plate and movable pressing plate under the pressure of the pressing device. Industrial filtering paper or filtering cloth plays the role of filtration.
• There are two liquid holes equipped on the accordant places of filter plate and frame. After pressed, these holes form two integrated Channels. The waste oil is accessed from the trigonal side of the lug, filtered in the filtering chamber, pumped out from the fan-shaped side of lug, and finally clean oil is obtained.
• While filtering, the waste oils are distributed to all the filter frames through the input channel, then enter into filter plates’ liquid holes after passing through industrial papers. Finally, clean oil is integrated into the output channels and pumped outside.
• Meanwhile, the waste residues stay on the industrial paper surface, some water content is also absorbed by the papers. When the waste residues and water content are increased to a certain amount, the filtering resistance is also increased, when it’s up to 0.2 ~ 0.35 MPa, the filtration process should be stopped and filtering paper has to be replaced or cleaned.
• The Gear Oil Pump and its motor are joined by a flexible rubber gasket. A relief valve is installed at the bottom of oil pump to avoid mechanical troubles because of overhigh pressure. Before delivery in factory, we will set the max pressure value to 150％PN. Customer can adjust this value according to the actual situation, but the value can not be over the max value.
• The gear oil pump and motor are installed under the filtering bed. Oil pump transfers the oil to the filtration system through a discharge pipe and thrust plate. The oil pump is lubricated by the transferred oils.
• Coarse filter is installed before the suction port, it’s used to remove the big-size particles and avoid the oil pump’s breakdown from the big-size particles’ entry.
• Coarse filter should be cleaned periodically: remove the screws & bolts, remove the cover, then take out the filter strainer to clean directly.
• If there is some oil remaining in the chamber, open the oil return valve, and suck them away to avoid the oil overflowing outside of the machine.
