Description

technical field [0001] The invention relates to the technical field of filter cleaning, in particular to a fully automatic backwashing self-cleaning filter for filtering lubricating oil and fuel oil. Background technique [0002] The liquid filter commonly used in the market is generally a manual duplex filter. The filter has two chambers. When the filter element of one chamber is put into operation, the filter element of the other chamber is used for standby. The filter filters the medium through the filter element, and the large impurity particles stay on the inlet side of the filter element, while the clean medium comes from the other side of the filter element. The working state of the two chambers can be manually switched through the conversion valve on the filter, the spare chamber is put into work, the working chamber is cut off, and the filter element of this chamber is manually maintained and replaced. [0003] This kind of filter has a simple structure and can mee...
