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....

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.

Description

technical field [0001] The invention relates to the technical field of pump seals, in particular to a split pump seal with a sealed oil passage. Background technique [0002] Water pumps used in many fields. Among them, submersible pumps and semi-submersible pumps are widely used. If the pump has a submersible function, it needs to have good sealing characteristics. The sealing characteristics of the water pump play an extremely important role in good working performance. In traditional submersible pumps, Waterproof seals need to be installed, but the current waterproof seals on the market are simple in structure, and the seals and connectors are mainly bolted and fixed by external assembly mechanisms, resulting in a large external volume, inconvenient loading and unloading, and limited airtightness. Moreover, the external assembly mechanism has been exposed for a long time, and the safety and firmness are limited. Contents of the invention [0003] The technical problem...
