Abstract

The invention relates to the technical field of pump seals, in particular to a split-type pump seal with a sealed oil passage, which includes a central main seal ring, a left seal joint located on the left side of the main seal ring, and a left seal connector located on the right side of the main seal ring. The right-hand seal connector on the side. A split-type pump seal with a sealed oil passage of the present invention is provided with an integral structure side seal ring with an internal annular oil cavity and an extrusion sealing hole at the opening position on both sides, and has an extrusion head inside the sealing connection head. The oblique extrusion screw is used to squeeze and close the extrusion sealing hole, thereby fixing the corresponding position of the sealing joint and the sealing oil chamber, so that the sealing performance of the entire seal is greatly improved, and the fixing mechanism is arranged inside to reduce the external space Occupy, greatly improving the firmness and stability of the seal.

Example Embodiment

[0013] The present invention will now be described in further detail with reference to the drawings. These drawings are all simplified schematic diagrams, which merely illustrate the basic structure of the present invention in a schematic manner, so they only show the structures related to the present invention.
[0014] figure 1 with figure 2 A split pump seal with a sealed oil passage is shown, including a central main seal ring 1, a left seal connector 2 on the left side of the main seal ring 1, and a right seal connector on the right side of the main seal ring 1. The sealing connector 3, the left side and the right side of the main sealing ring 1 are located at the opening positions on both sides of the inner through hole. Both sides have an integrated structure to improve the sealing performance of the assembly position. The lateral sealing ring 4 is close to the main sealing ring 1. The outer side surface is a slope that gradually decreases from the inside to the outside. The inner arc surface of the main seal ring 1 has three internal limit blocks 5, the left sealing connector 2 right side wall and the right sealing connector 3 left side wall The upper part is provided with an internal limit groove 6 which is matched with the internal limit block 5. The left sealed connector 2 and the right sealed connector 3 are sleeved in the corresponding position on the internal limit block 5 and inside through the internal limit groove 6 The limit block 5 is clamped together. The outer side wall of the left sealing connector 2 and the right sealing connector 3 are provided with an internally threaded expansion hole 8 with a built-in extrusion screw 7. The outer top of the extrusion screw 7 is the inner diameter of the outer mesh The larger and larger cone-shaped extrusion head 9, the inner side of the side sealing ring 4 is provided with an annular oil cavity 10 for filling the sealing oil, and the side sealing ring 4 is provided with the position corresponding to the extrusion screw 7 and the extrusion The head 9 is fitted with an extrusion sealing hole 11.
[0015] Further, the left sealing connector 2 and the right sealing connector 3 have the same size. Further, the inner side edge of the lateral sealing ring 4 is provided with a sealing groove with a built-in rubber sealing ring 12, and further, the lateral sealing ring 4 The minimum inner diameter is the same as the maximum outer diameter of the left sealing connector 2. The split pump seal with a sealed oil passage of the present invention is provided with an annular oil cavity 10 and an extrusion seal at the opening positions on both sides. The side sealing ring 4 of the integral structure of the hole 11 squeezes and closes the squeeze sealing hole 11 through the inclined extrusion screw 7 with the squeeze head 9 inside the sealing connector, thereby fixing the corresponding position of the sealing connector and the sealing oil The cavity 10 greatly improves the sealing performance of the entire seal, and the fixing mechanism is arranged inside, which reduces the external space occupation, and greatly improves the firmness and stability of the seal.
[0016] Taking the above-mentioned ideal embodiment according to the present invention as enlightenment, through the above-mentioned description content, relevant workers can make various changes and modifications without departing from the scope of the technical idea of ​​the present invention. The technical scope of the present invention is not limited to the content of the description, and its technical scope must be determined according to the scope of the claims.
