Summary of the invention
The purpose of this utility model is to provide chlorine press rotation axis seal, sealing performance is very high.
To solve the above-mentioned problems, the technical solution adopted in the utility model is as follows:
Chlorine press rotation axis seal, including cabinet 1, rotary shaft 2, impeller 3, impeller 3 are connect with rotary shaft 2, and rotary shaft 2 is set
In in cabinet 1, which is characterized in that be equipped with seal assembly 4 between rotary shaft 2 and cabinet 1,4 two sides of seal assembly are equipped with and cabinet
The stop collar 5 of connection, the seal assembly 4 include covering carbocyclic ring 41, gasket ring 42, labyrinth seal ring 43 in rotary shaft 2, carbocyclic ring
41, it is equipped with outside gasket ring 42 and squeezes fixed ring 44, the inner ring for squeezing fixed ring 44 is equipped with sealing ring 47, squeezes fixed ring 44 and pad
Ring 42 is equipped with venthole 45, and venthole 45 is communicated with the cavity inside labyrinth seal ring 4, and venthole 45 connects elevated pressure nitrogen tracheae
46, it is cased with compressed spring 7 respectively in the rotary shaft 2 between 4 two sides of seal assembly and stop collar.
The rotary shaft 2 of optimization, 4 inside of opposing seal component is equipped with alloy wear-resisting set 6.
Compared with prior art, the utility model advantageous effects are as follows:
It squeezes fixed ring 44 and plays the role of radial positioning, carbocyclic ring 41, gasket ring 42, labyrinth seal ring 43 to seal assembly 4
Alternate installation is simultaneously compressed by compressed spring 7, and compressed spring 7 plays the role of axial limiting and compensation.Rotary shaft and carbocyclic ring 41
Contact, 41 quality smoother of carbocyclic ring reduce damping of the seal assembly to rotary shaft.In cavity inside labyrinth seal ring 4
Filled with high pressure nitrogen, seal assembly air pressure inside is greater than external chlorine gas pressure, has prevented chlorine and has entered seal assembly, has reduced chlorine
Gas extends service life of equipment to the corrosive damage of entire unit.
