Abstract

The invention discloses an integral floating sealing structure, which relates to the technical field of fluid machinery, and comprises a rotating part and a static part; the rotating part comprises ashaft sleeve, a moving ring and a driving ring, the shaft sleeve sleeves the equipment rotating shaft, and the driving ring and the moving ring sleeve the shaft sleeve; the static part comprises an end cover and a static ring in butt joint with the moving ring, and the static ring and the end cover are arranged on the shaft sleeve in a sleeving mode. The outer edge of the end cover is connected with the equipment cavity. Split floating seals are combined into an integral structure, so that the assembly precision of the seal is ensured; the seal does not need to be adjusted in the mounting process, the mounting difficulty is reduced, and the floating seal is convenient to mount and use. The integral floating sealing structure can be applied to fluid machinery and other related equipment widely in many fields, is particularly suitable for harsh operation conditions that media contain impurities, and is high in practicability.

Description

technical field [0001] The invention relates to the technical field of fluid machinery, in particular to an integral floating seal structure. Background technique [0002] Currently. The existing floating seals usually adopt a split structure, which is not only inconvenient to install and use, but also prone to installation quality problems. Contents of the invention [0003] The purpose of the present invention is to provide an integral floating seal structure, which can achieve the package sealing effect by preinstalling the floating seal in the integral assembly. [0004] To achieve the above object, the present invention provides the following scheme: [0005] The invention provides an integral floating seal structure, which includes a rotating part and a stationary part; The rings are both sleeved on the outer circumference of the shaft sleeve; the stationary part includes an end cover and a static ring docked with the moving ring, and the static ring and the end c...
