| description | The invention discloses a reciprocating oil seal assembly for an emulsion pump. The reciprocating oil seal assembly for the emulsion pump comprises a sealing shell, a first annular groove, a second annular groove, a third annular groove, a first sealing element, a second sealing element and a third sealing element. A piston rod of the emulsion pump can penetrate through a piston hole, and a gap is formed between the circumferential surface of the piston rod and the hole wall surface of the piston hole. The first annular groove and the third annular groove are arranged at an interval in the axial direction of the piston hole, and the third annular groove is located between the first annular groove and the second annular groove in the axial direction of the piston hole. The first sealing element is arranged in the first annular groove, the second sealing element is arranged in the second annular groove, and the third sealing element is arranged in the third annular groove, so that the gap between the circumfere |
