Abstract
The utility model relates to a machinery sealing, which comprises a sealing gasket (1), a static ring (2), a static ring O-shaped ring (3), a moving ring friction plate (4), a moving ring body (5), a moving ring O-shaped ring (6), a hook spring (7), a locating ring (8), and a locating ring screw (9). The axial sealing element and the radial sealing element of the static ring and the moving ring are separated; the moving ring body can be made rotate synchronously with a shaft or a wheel by the hook spring; neither the rear end face of the moving ring, nor the front end face of the locating ring produces scratch. The utility model can be widely used on the equipment for conveying oil and water with weak acid, and middle or low temperature (lower than 100 DEG centigrade).
Description
The utility model is belong to mechanical seal a kind of.
Axially and the radially seal element of usefulness of the rotating ring of mechanical seal at present, stationary ring all is indiscrete, be whole, seal element as leather cup formula, square ring formula, when rotating ring rotates, stationary ring and rotating ring unbalance stress, cause the seal element distortion, make easily and carry liquid to extrude, produce and leak from big gap location.The both ends of the spring face contacts with the front-end face of rotating ring body ear end face and positioning ring by spring force and frictional force and drives the rotating ring rotation, when wanting to rotate synchronously with axle or wheel, spring end face can make rotating ring body ear end face or positioning ring front-end face scratch the end, destroy sealing surface easily, the leak of liquid amount is strengthened.Just in the mechanical seal at present, also not identical with the utility model.
The purpose of this utility model: scratch problems such as end for solving on-stream leakage of diesel engine of diesel locomotive water pump seal and water pump vane end face, develop a kind of mechanical seal and can satisfy the problem that the diesel pump water seal is not leaked.
The purpose of this utility model is achieved in that this mechanical seal structure is by sealing gasket (1), stationary ring (2), stationary ring zero type circle (3), rotating ring friction plate (4), rotating ring body (5), rotating ring zero type circle (6), hook spring (7), positioning ring (8) and positioning ring screw (9) are formed, car has curve bath outside stationary ring (2), stationary ring zero type circle (3) is housed in the groove, between rotating ring friction plate (4) and the rotating ring body (5) in the hole car curve bath is arranged, rotating ring zero type circle (6) is housed in the groove, hook spring (7) both ends of the surface respectively have a garden cylindricality hook, one end is packed on rotating ring body (5) ear end face in the hole, and the garden cylindricality hook of the other end is packed on positioning ring (8) front-end face in the hole.
During use, sealing gasket (1) and the stationary ring (2) that installs stationary ring zero shape circle (3) are packed in body or the lid together, to assemble rotating ring body (5), hook spring (7), positioning ring (8) again is contained on axle or the axle sleeve together, stationary ring (2) is contacted with rotating ring friction plate (3), its pressure big be that reaction force by after hook spring (7) compression is adjusted within the scope of design of regulation for a short time, when spring pressure be transferred to suitable after, with positioning ring screw (9) with positioning ring (8) be fixed on the axle or axle sleeve on.When axle rotated, positioning ring on the axle (8) drove hook spring (7), rotating ring body (5) and rotates synchronously together.
The utility model compared with prior art has following advantage:
1, stationary ring, rotating ring axially and seal element radially be split, make seal element only bear single load bearing, axial seal as stationary ring (2) is born by sealing gasket (1), radially be to seal by stationary ring zero type circle (3), stationary ring (2) radial clearance can be dwindled like this, and same rotating ring body (5) radial clearance also can be dwindled, and quiet, rotating ring can be reduced by fluctuation, the seal element stress deformation is compared stressed single with leather cup formula seal element, sealability is more reliable.
2, hook spring (7) both ends of the surface buckle pin does not have hook pin good than both ends of the spring face, during assembling, hook pin on hook spring (7) both ends of the surface is respectively charged into and reaches in positioning ring (8) the front end face in the face of rotating ring body (5) rear end, guarantee rotating ring body (5) and axle or wheel rotation synchronously, can avoid spring end face and rotating ring body (5) or positioning ring (8) end face to relatively rotate and the scraping end face falls last problem.
3, seal element adopts zero RunddichtringO of NBS, is convenient to maintenance and accessory and prepares.
4, friction plate material quiet, rotating ring is to adopt high-abrasive material to make, and working life is longer.
5, this mechanical seal can be widely used in conveying weak acid, in, use on the equipment of low temperature (below 100 ℃) oil, water.
Description of drawings:
Fig. 1 is the mechanical seal schematic representation
(1) sealing gasket, (2) stationary ring, (3) stationary ring zero type circle, (4) rotating ring friction plate, (5) rotating ring body, (6) rotating ring zero type circle, (7) hook spring, (8) positioning ring, (9) positioning ring screw.
Embodiment:
Be placed on the water pump through the pump stand test by the HEX-40 mechanical seal of above-mentioned mechanical seal structure manufacturing, be contained in the east wind 4C of the Dalian locomotive works diesel engine of locomotive warm pump and the formal service testing of high temperature pump after the pass the test again and reprocess leakage.
Above HEX-40 mechanical seal is contained in again on Beijing type of Erqi Locomotive Works, Beijing and east wind 7 type locomotives and tests, and thinks that this mechanical seal uses reliably, does not reprocess and quality problems, and rational in infrastructure have a practicability.
