This utility model relates to the field of sealing technology, specifically to a wear-resistant packing for a pumping unit. It includes a rubber substrate, with an anti-corrosion layer and a wear-resistant layer sequentially arranged from the inside out on the outer side of the rubber substrate. An upper rubber layer is bonded and sealed to the upper end of the wear-resistant layer, and an upper adhesive layer is coated on the upper end of the upper rubber layer. A lower rubber layer is bonded and sealed to the lower end of the wear-resistant layer, and a lower adhesive layer is coated on the lower end of the lower rubber layer. An insert rod is fixed inside the lower end of the rubber substrate, with its lower end penetrating the anti-corrosion layer and the wear-resistant layer and extending into the lower rubber layer. Multiple support frames are arranged inside the rubber substrate, and the support frames are fixedly connected to an elastic steel strip. The wear-resistant layer, anti-corrosion layer, and rubber substrate of this utility model form a gradient protection system. Combined with the flexible wrapping of the bonding interface by the upper and lower rubber layers, it achieves dual isolation from chemical corrosion and mechanical wear, ensuring long-term sealing integrity.

This invention belongs to the field of protective coating technology and discloses an environmentally friendly ceramic-graphene composite insulating protective coating and its preparation method. The coating comprises an aqueous epoxy resin, an inorganic ceramic precursor film-forming component, a core-shell-interface modified insulating graphene functional filler, an aqueous curing agent, and additives. The functional filler includes a graphene core, an Al2O3 insulating shell continuously coated on its surface, and an epoxy reactive organosilicon interface layer grafted onto the outer surface of the Al2O3 insulating shell. By first preparing the functional filler and then compounding it with the aqueous epoxy resin and the inorganic ceramic precursor film-forming component to form a film, the resulting coating possesses excellent insulation, protection, and adhesion stability, making it suitable for insulating and protecting metal substrate surfaces.

This invention provides an intelligent art hanging device for art design, comprising: a parallel plate, a partition screen, a support column, a slide rail, and a hanging structure. The partition screen on the upper edge of the parallel plate is spaced to the support column. The support column determines the position of the hanging structure via the slide rail, and the hanging structure is positioned above the parallel plate via the slide rail of the support column. This invention improves the hanging structure by using two sets of adjusting components that pass through the slide rail of the support column and are fixed to the locking slots at both ends of the balance bar. This allows for direct manual adjustment of the height of the hanging body, improving the convenience of height adjustment for the artwork. Furthermore, the lower force-bearing structure of the welded plate of the hanging body allows the artwork to be directly embedded in the hanging structure, replacing the original bolt locking process. This avoids deformation of the artwork caused by continuous pressure on the hanging position, thus effectively improving the practical performance of the hanging device.
