The current method of oil transportation is generally to converge the lubricating oil from the oil return points of the equipment into the oil return main pipe of the equipment oil tank, and then install a filter between the oil return main pipe and the tank inlet to achieve the purpose of recovering harmful impurities in the lubricating oil. However, this method has disadvantages such as small filter area, filter failure or damage that is not easy to detect, large amount of PTFE gasket and filter, and slow oil return speed. Once the filter is damaged or the operation is wrong, the dirty oil and the filter are easy to enter the fuel tank directly, causing the previous effort to be lost.
