[0018] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0019] The high-efficiency piston oil pump can filter impurities in the oil through the filter disc in the filter tube during the oil or other liquid delivery process through the filter mechanism, thereby improving the use effect of the oil and the service life of the equipment, and can realize automatic connection and fixation between the filter tube and the oil outlet pipe, thereby improving the efficiency of installation and disassembly. When the filter disc is used for a long time, the filter disc can be replaced to improve the filtering effect. First, the rear side of the filter tube is aligned with the front side of the oil outlet pipe and corresponds to the position of the first threaded rod. The first servo motor drives the rotating rod to rotate, so that the rotating rod drives the first spur gear to rotate. When the first spur gear rotates, it drives the internal gear to rotate through the second spur gear. When the internal gear rotates, it drives the support frame to rotate in the limit groove. The inner gear can be supported and limited by the support frame through the inner gear. When the inner gear rotates, it will drive the third spur gear meshing on the inner side to rotate, so that the third spur gear drives the first threaded rod to move forward and backward in the oil outlet pipe, and the front side of the first threaded rod is threadedly connected to the rear side of the filter tube, so that the filter tube and the oil outlet pipe are fixedly connected, and the filter tube can be installed with high efficiency. Then the filter plate is slid into the filter tube. When the filter plate slides into the filter tube, the limit block will be squeezed, so that the limit block drives the pull rod to move up and down in the L-shaped frame through the circular block, and the first spring is deformed. When the filter plate is placed, the first spring is reset, driving the circular block and the limit block to move downward, so that the limit block limits the filter plate to ensure the stability of the filter plate.

[0020] The high-efficiency piston oil pump can clean the impurities attached to the rear side of the filter disc when the filter disc performs filtering work for a long time through the cleaning mechanism. This can not only improve the filtering quality, but also increase the oil circulation speed in the filter tube. When the filter disc performs filtering work, the second servo motor drives the second threaded rod to rotate, so that the second threaded rod drives the mounting seat to rise and fall. When the mounting seat is lifted and lowered, the cleaning brush and the rear side of the filter disc are driven to contact each other, so as to clean the impurities attached to the filter disc and improve the filtering efficiency. When the mounting seat is lifted and lowered, it will slide around the sliding rod, and the sliding rod can limit the mounting seat to make the movement more stable. When the cleaning brush needs to be replaced, it only needs to remove the fixing bolt, slide the new cleaning brush into the front side of the mounting seat, and then fix the cleaning brush to the mounting seat through the fixing bolt.

[0021] The high-efficiency piston oil pump can collect the impurities cleaned on the filter disc through the collection mechanism, and in the process of collecting, a part of the oil will follow the impurities into the collection box, at this time, the impurities can be further filtered through the filter plate, and the filtered oil can be reused, saving resources and improving the quality of filtering. First, the collection box is slid into the bottom of the filter tube. When the collection box slides in, the two sides of the collection box will squeeze the card block, so that the card block drives the fixed rod to move left and right in the movable groove, and the second spring is deformed. When the collection box slides into a certain position, the squeezing of the card block will be released, and the second spring will reset, so that the fixed rod drives the card block to slide into the card slot, and the collection box is initially limited. Then, the fixing pin is threadedly connected to the connecting block, and the top of the fixing pin is threadedly connected to the bottom of the filter tube, so that the collection box can be further fixed. When collecting, it only needs to slide the baffle out a certain distance, and the cleaned impurities will fall on the top of the filter plate, and further filtering will be performed. The filtered oil will be stored in the collection box for reuse. BRIEF DESCRIPTION OF THE DRAWINGS
