Abstract
The utility model relates to a magnetic machinery sealing, which comprises a sealing element (1), a static ring (2), a moving ring friction plate (3), a moving ring body (4), a sealing element (5), a spring (6), a locating ring (7), and a locating ring screw (8), wherein, the inner of the static ring (2) is inlaid with a magnetic ring (or a steel ring) (9); a steel ring (or a magnetic ring) (10) is inlaid between the moving ring friction plate (3) and the moving ring body; when the inlaid static ring (2) makes contact with the moving ring, the inlaid static ring (2) and the moving ring suck each other. The utility model can be widely used on the machinery with vibration and impact, and on the machinery which requires no leakage of mechanical sealing.
Description
The utility model is belong to mechanical seal a kind of.
The mechanical seal of usefulness at present on the equipment that is used in vibration or impacts, is easy to make the distortion of mechanical seal damaged surfaces or seal element, annex, and the liquid of conveying is extruded in big place from the gap, produces and leaks.Also not identical with regard to present mechanical seal with the utility model.
The purpose of this utility model: the mechanical seal that vibration, impact device is arranged, do not allow the equipment of leak of liquid to use for solution.
The purpose of this utility model is achieved in that its structure is identical with the existing machinery sealing, all be by seal element (1), stationary ring (2), rotating ring friction plate (3), rotating ring body (4), seal element (5), spring (6), positioning ring (7) and positioning ring screw (8) are formed, in stationary ring (2), stud with magnetic ring (or steel loop) (9), stud with steel loop (or magnetic ring) (10) between rotating ring friction plate (3) and the rotating ring body (4), the stationary ring (2) that studs with magnetic ring (or steel loop) (9), be referred to as magnetic force stationary ring (2) later on, studding with steel loop (or magnetic ring) (10) in the rotating ring body (4), be referred to as magnetic force rotating ring body (4) after studding with rotating ring friction plate (3) outward, when contacting with magnetic force rotating ring body (4), should inhale mutually magnetic force stationary ring (2), all can be bumped into magnetic ring (9) and (10) in stationary ring (2) and the rotating ring body (4), two loop contacts should be inhaled mutually, stationary ring (2) is made with all available magnetic material of rotating ring friction plate (3), when contacting with rotating ring friction plate (3), inhales mutually stationary ring (2), magnetic force stationary ring (2) is inhaled the sealing surface good seal performance mutually with magnetic force rotating ring body (4) contact like this, under the situation of shock and vibration, also be difficult for separately, not fragile sealing surface, can guarantee to carry liquid not leak, the big I of magnetic ring or steel loop is determined according to the requirement of use occasion and the size of sealing magnetic ring magnetic force, the available integral material that magnetic ring is little is made, the integrated ring of available block shape magnet stacks that magnetic ring is big.The material of magnetic ring can be iron Al-Ni-Co series alloy, and siderochrome cobalt mercury magnetic alloy, the permanent magnetic alloy of iron cobalt vanadium, the permanent magnetic alloy of aluminium nickel cobalt, Nd-Fe-Bo permanent magnet material also have RE permanent magnetic alloy.The material of steel loop can be carbon steel, alloyed steel (except the body steel of the third constellations difficult to understand), high speed steel, cemented carbide.If rotating ring friction plate (3) is with carbon steel, alloyed steel (except the body steel of the third constellations difficult to understand), high speed steel in addition, when cemented carbide is made, can not inlay steel loop (9), (10) in the rotating ring body (4).
The utility model compared with prior art has following advantage:
1, owing to stud with magnetic ring (9), (10) in stationary ring (2) and the rotating ring body (4), two loop contacts are inhaled mutually, the sealing surface that contacts, and no gap, sealability is more reliable, can be used on the equipment of vibration, impact and requires on the equipment of good seal performance.
2, magnetic ring (9) can be bumped in the stationary ring and rotating ring of various mechanical seals with (10).
Description of drawings:
Fig. 1 is the schematic representation of magnetic mechanical seal
(1) seal element, (2) stationary ring, (3) rotating ring friction plate, (4) rotating ring body, (5) seal element, (6) spring, (7) positioning ring, (8) positioning ring screw, (9) magnetic ring (or steel loop), (10) steel loop (magnetic ring).
