A kind of mechanical seal of the gland axle sleeve with silicon carbide wear-resistant coating, comprising: one end with the axle sleeve of shoulder, gland,
Stationary ring and rotating ring, the axle sleeve are socketed on axis, and the axle sleeve is fixed with drive ring, the rotating ring and axle sleeve far from shoulder one end
Shoulder position connection, the stationary ring and rotating ring end contradict, and are socketed with gland on the outside of the axle sleeve, at one end of the stationary ring
On the inside of gland, it is equipped with throw-out collar and counterbalance spring between one end and gland of the stationary ring, is equipped between the gland and axle sleeve
The one end of gland far from stationary ring is arranged in outside framework oil seal, the outside framework oil seal, and the side of the outside framework oil seal is equipped with by locating piece
The cover board being fixed, the gland are equipped with corrosion cap close to the end face of stationary ring.
As improved, contact of the axle sleeve with the contact jaw of axis, axle sleeve with the contact jaw of rotating ring and gland with stationary ring
End is equipped with O-ring.
As improved, the material of the stationary ring, rotating ring and corrosion cap is pressureless sintering silicon carbide.
As improved, the drive ring is by passing through being fixed on axis of axle sleeve.
As improved, the contact position of the outside framework oil seal and axle sleeve is coated with coat of silicon carbide.
The utility model has the following beneficial effects:
The utility model is equipped with O-ring in the contact jaw of each component, and using multi-stage sealed form, stationary ring is in bullet
Fit-state is kept with the rotating ring moment under the action of spring and Fluid pressure, to reach the state of sealing, sealing effect is good, is locating
The silicon carbide of one layer of wear-and corrosion-resistant is added in the gland surfaces of media end, considerably increases the service life of mechanical seal, it can also
To replace expensive stainless steel material, use cost is saved, and readily replaceable.
