Description

Technical Field

[0001] The utility model relates to the technical field of blowers, in particular to an elastic compensation device for dynamic and static seals of a blower rotor. Background Art

[0002] The elastic compensation device is usually an element designed in the blower rotor sealing structure. It uses the elastic force of elastic elements, such as springs, to compensate for the end face wear of the sealing pair to ensure a good fit of the sealing pair. This device is particularly critical in dynamic and static sealing structures because it can effectively deal with the wear that may occur in the sealing pair during movement, thereby ensuring the stability of the sealing performance. During the operation of the blower, the end face of the sealing pair will gradually wear due to friction. The elastic compensation device uses the elastic force of the elastic element to promote the axial movement of the dynamic ring, thereby compensating for this wear and ensuring that the sealing pair always maintains a good fit.

[0003] However, the existing technology has the following problems when it is actually used:

[0004] In the prior art, it is inconvenient for workers to assemble and disassemble the elastic compensation device, resulting in the problem that the internal parts of the internal elastic compensation device may be worn when the blower is in rotation for a long time when the blower is working for a long time.

The inner side wall of the sleeve 4 is clamped with a clamping shaft 5 for positioning, and the outer surface of the clamping shaft 5 is clamped with a spring seat 6 for positioning. A clamping tube 13 for positioning is fixedly connected to one side of the connecting block 2, and a limiting hole 14 for positioning is opened on the other side of the connecting block 2. A bolt 15 for fixing is inserted into the side of the positioning plate 3, and a nut 16 for fixing is threadedly connected to one end of the bolt 15. A spring 17 for buffering is fixedly connected to the side of the spring seat 6, and one end of the spring 17 is fixedly connected to a dynamic ring 18. A first sealing ring 19 is fixedly installed on the inner side wall of the dynamic ring 18, and a static ring 20 is detachably connected to the side of the dynamic ring 18. The outer surface of the static ring 20 is clamped with a second sealing ring 21.
