Description
Technical field
The utility model relates to sealing element technical field, a kind of specifically mechanically-sealing apparatus.
Background technique
Mechanically-sealing apparatus is by least a pair of end face perpendicular to rotation axis in Fluid pressure and compensation mechanism elastic force
Under the action of and the cooperation of auxiliary seal under keep fitting, and the device for preventing fluid leakage constituted with respect to sliding.
Traditional mechanically-sealing apparatus is mainly by: end face seal pair (stationary seal ring and rotary packing ring), elastic element (such as bullet
Spring), auxiliary seal (such as O-ring), driving member (such as trundle and transmission screw), rotation preventing device (such as stop pin) and fastener (such as
Spring base, throw-out collar, gland, holding screw and axle sleeve) etc. composition.
In use, most of mechanical seals belong to contact seal.Its mechanism be by rotary packing ring with it is quiet close
The contact face of seal ring fits closely under the action of sealing-fluid pressure and elastic element pressing force, and reaches with respect to sliding
Sealing.Phenomena such as friction, sliding are with abrasion occurs when work, on mechanical seal end surface simultaneously, friction is its essential characteristic.Machine
The operating condition of tool seal face friction is generally divided into: fluid friction, mixed film friction and boundary friction three classes, but absolutely cannot be for a long time
Dry friction.
When seal face is in high speed rotation, shaft can rub with stationary seat, stationary seal ring and rotary packing ring, rub
Wipe generate wearer can be present in the space between shaft and stationary seat, stationary seal ring and rotary packing ring, cause shaft with it is close
The abrasion of sealing assembly, and wearer can be deposited in stationary seal ring and rotary packing ring binding face as shaft rotates after rubbing for a long time
It is formed by gap, it is difficult to clear up.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of mechanically-sealing apparatus, and it is broken to can effectively prevent abrasion
Bits remain in the space between sealing device and shaft, avoid the abrasion of sealing device and shaft.
Technical solution adopted in the utility model is: it includes a retainer, is equipped with rotating seat and stationary ring in retainer
Seat, retainer are fitted closely by elastic component and stationary seat, are respectively equipped with rotary packing ring and static seal on rotating seat and stationary seat
Ring, rotary packing ring are bonded with stationary seal ring and can be equipped with sealing ring, dynamic sealing between rotating seat and rotary packing ring in relative rotation
Ring outer diameter is equipped with fan, and stationary seal ring inner wall is equipped with the first annular groove, and rotary packing ring inner wall is equipped with the second annular groove, the first ring
Slot and the second annular groove are close to stationary seal ring and rotary packing ring binding face, and stationary seat inner wall is equipped with third annular groove, third annular groove
Close to stationary seat and stationary seal ring binding face.
Preferably, elastic component is spring.
Preferably, the first annular groove, the second annular groove and third annular groove cross section are semicircle or arc-shaped.
The mechanically-sealing apparatus of the utility model, advantage are as follows: stationary seal ring inner wall is equipped with the first annular groove, dynamic sealing
Ring inner wall is equipped with the second annular groove, and the first annular groove and the second annular groove are close to stationary seal ring and rotary packing ring binding face, so that quiet
Sealing ring and rotary packing ring binding face both sides are designed with annular groove, when clast moves to binding face as rotary packing ring rotates, absolutely
It is most of to first pass through two annular grooves, to utmostly reduce talus accumulation at the binding face of stationary seal ring and rotary packing ring
In gap, clast can be only deposited in the first annular groove and the second annular groove, the last clast that need to only clear up in annular groove；Work as clast
When moving to the binding face between retainer and stationary seal ring as shaft rotates, stationary seat inner wall is equipped with third annular groove, the
Close to stationary seat and stationary seal ring binding face, most of clast can be deposited in third annular groove three annular grooves, to utmostly subtract
The talus accumulation between talus accumulation and stationary seal ring and stationary seat between few stationary seal ring and rotary packing ring.
