Embodiment Construction

[0011] Below the present invention will be further described in conjunction with the embodiment in the accompanying drawing:

[0012] Such as figure 1 As shown, the present invention mainly includes an intermediate connecting pipe 2, and the intermediate connecting pipe 2 is integrally connected with the sealing body 7 through bolts. A sealing ring 3 is provided between the intermediate connecting pipe 2 and the sealing body 7 , and the intermediate connecting pipe 2 and the sealing body 7 are sealed by the sealing ring 3 .

[0013] A rotating shaft 1 is arranged inside the intermediate connecting pipe 2 and the sealing body 7, and a deep groove ball bearing 4 and a double-end mechanical seal 6 are sequentially arranged on the rotating shaft 1 from top to bottom. The double-end machine seal 6 prevents the deep groove ball bearing 4 from contacting with liquid, effectively guarantees the service life of the bearing, and improves the service life and reliability of the water pu...

Abstract

The invention relates to a sealing structure, in particular to a submerged pump sealing structure, and belongs to the technical field of sealing. The submerged pump sealing structure comprises a middle connecting pipe, and the middle connecting pipe is integrally connected with a sealing body through a bolt. A rotary shaft is arranged in the middle connecting pipe and the sealing body, and a deep groove ball bearing and a double-end-face mechanical seal are arranged on the rotary shaft from top to bottom in sequence. The submerged pump sealing structure is simple, compact and reasonable in structure, the double-end-face mechanical seal is added, the bearing is prevented from being in contact with liquid, the service life of the bearing is effectively guaranteed, the service life of the submerged pump is prolonged, and the reliability of the submerged pump is improved.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure of a submerged pump, belonging to the technical field of sealing. Background technique [0002] At present, the submerged pump is placed in the liquid to work, and the lower bearing assembly of the submerged pump is also immersed in the liquid. Because the liquid contains particulate impurities and has a certain viscosity, the lower bushing and the lower bearing wear quickly in the liquid environment, and strangulation occurs, which reduces the service life of the submerged pump. Contents of the invention [0003] The purpose of the present invention is to overcome the above disadvantages, so as to provide a submerged pump sealing structure, which can avoid the contact between the bearing and the liquid, and improve the service life and reliability of the water pump. [0004] According to the technical solution provided by the present invention, the sealing structure ...
