Mechanical sealed concept
Called mechanical seal (mechanical
seal) is means least 1 pairs perpendicular rotating axis end
face in fluid pressure and compensation institutions elastic (or
magnetic) role under and auxiliary sealed tie to maintain paste
merger relative sliding consisting prevent fluid leak devices.
Elastic loading mechanism and the secondary seal is a metallic
bellows mechanical seal which we call metal bellows seal.
In light seal there use rubber Bellows make auxiliary sealed, rubber
bellows elastic limited generally need supplemented spring to meet
load elastic.
Mechanical sealed composition
Mainly following four categories parts.
·Main components: Activity ring and static ring.
·Auxiliary seals: seals (there O shaped, X shaped, U type, wedge,
rectangular flexible graphite, PTFE coated rubber O ring etc.).
·Elastic compensation institutions: spring, push ring.
·Transmission pieces: shells Kei Block and key or various screw.
Mechanical seal is quite soft packing seal
Advantages:
·cope Canton mechanical seal can used Cold, heat, vacuum,
high pressure, different speed and various corrosive medium and
containing abrasive medium etc. sealing.
·Friction power consumption small mechanical seal friction
power only soft packing seal 10% ~ 50%;
·Sealed reliable long cycle operations, sealing state very stable
leakage small, press rough statistics, its leakage general only soft
filler sealed 1 / 100;
·Long life in oil, water class medium general reach 1 ~ 2 years or
more, in chemical medium usually can more than six months;
* Shaft or bushings are basically free from wear;
· Maintenance cycle long end face worn automatically compensation
general, without recurrent maintenance;
· Vibration good on rotating axis vibration, partial pendulum and
axis on sealed cavity skew insensitive;
* About the current number of factories "zero leakage" needs,
packing not meet this requirement; not adapt to a wide range of
arbitrary bigger, but in factories, often replacing or maintenance
will plant great loss.
The following shortcomings:
· Disposable high investment.
·Structure was complex manufacturing processing demanding;
·Occurs contingency accident, handling more difficult;
·Installation and replacement troublesome and requested workers
certain installation technical level;
