Description
Technical field
The utility model is related to a kind of sealing structure, and the packaging type double mechanical for referring in particular to be applied in fluid pump is close
The improvement of seal structure.
Background technology
Mechanically-sealing apparatus are widely used in the equipment such as blower fan, pump, reactor, and when needing, the fluid of sealing is poisonous, easy
When combustion, explosive or medium self-lubricity difference and tighter seal request, it is necessary to adopt double mechanical seal.On applicable industry
Double mechanical seal used its structure mostly is inside and outside layer ring type and arranges, in the structure shown here by outer layer rotating ring and outer layer stationary ring group
Into primary seal, secondary sealing is constituted by internal layer rotating ring and internal layer stationary ring, it is this to seal the machine for carrying out ectonexine ring type setting to major and minor
Tool sealing means, though desired sealing effectiveness can be reached, in actual applications because secondary sealing is arranged in primary seal, then lead
The diameter of rotating ring and stationary ring is just relatively large in sealing, and correspondingly the diameter of seal face also increases therewith, i.e. seal face face
In increase, this just brings the increase of two aspect problems, one side seal face area to directly result in the friction produced during work to product
Calorific value increases, and seal face temperature will be raised, and the lubricating oil film between seal face will be destroyed, between seal face
Abrasion will aggravate, it is big that the end face seal structure of this major diameter there will naturally be friction calorific value, the short defect of service life；Separately
On the one hand it is the sealing property of guarantee mechanical seal, must be strict to the end face run-out degree tolerance of rotating ring and stationary ring during production and processing
Control, and also gradually increase as rotating ring and stationary ring diameter increase the difficulty to its end face run-out degree allowance control, it is clear that exist
The difficult defect of processing and manufacturing.
