Abstract
The invention relates to the filed of seal, in particular to an opposed type U-shaped surface magnetic mechanical seal, which consists of a stator ring (1) and a rotor ring (2). The opposed type U-shaped surface magnetic mechanical seal is characterized in that the stator ring (1) is provided with a stator ring positioning hole (7), a static seal (8), a stator ring surface (9) and a stator ring mounting hole (11); a stator ring magnetic bead (12) is arranged in the stator ring mounting hole (11); the rotor ring (2) is provided with a rotor ring mounting hole (3), a reinforced seal (5) and a U-shaped surface(10); a rotor ring magnetic bead (4) is arranged in the rotor ring mounting hole (3) on the rotor ring (2); the rotor ring magnetic bead (4) and the stator ring magnetic bead (12) of the stator ring (1) are oppositely attracted with each other, so that the stator ring surface (9) of the stator ring (1) and the U-shaped surface (10) of the rotor ring (2) are rotated in fixed positions to realize double end face inclusion seal; and the inner circle of the reinforced seal (5) is provided with a positioning O-shaped ring (6) which is automatically sealed with a crankshaft in a fixed position through the inner circle of the reinforced seal (5). The opposed type U-shaped surface magnetic mechanical seal has the advantages of simple structure, safe use, low cost and convenient maintenance, and can be widely applied in the fields such as pump, kettle, reducer, gear box, ventilator, fan and so on.
Description
Technical field:
The present invention relates to field of sealing technology, be specifically related to opposed type U profile magnetic mechanical seal.
Background technique:
Sealing is the core component of pump class, and it is directly connected to the working life of pump class, adopts patterns such as packing seal, reinforced seal, spring mechanical sealing for many years always; Directly wear and tear pump shaft, wasteful, life-span of packing seal and reinforced seal is short; though mechanical seal has overcome above-mentioned defective; take up room greatly but still have, can't be used for vertical pump, in start, cause leakage easily when shutting down, cost an arm and a leg, defective such as inconvenient maintenance.
Summary of the invention:
For overcoming above-mentioned technological deficiency, the invention discloses that a kind of volume is little, the life-span is long, price is low, leak free opposed type U profile magnetic mechanical seal.
To achieve the above object of the invention, the present invention adopts following technical proposal:
Described opposed type U profile magnetic mechanical seal is made up of stationary ring (1), rotating ring (2); It is characterized by: stationary ring positioning hole (7), sealing gasket (8), stationary ring face (9), stationary ring mounting hole (11) are set, dress stationary ring magnetic bead (12) in the stationary ring mounting hole (11) on stationary ring (1); Rotating ring mounting hole (3), reinforced seal (5), U profile (10) are set on rotating ring (2); Dress rotating ring magnetic bead (4) in the rotating ring mounting hole (3) on its rotating ring (2), the opposed adhesive of stationary ring magnetic bead (12) of rotating ring magnetic bead (4) and stationary ring (1), make U profile (10) position rotating of stationary ring face (9) Yu the rotating ring (2) of stationary ring (1), realize the Double End inclusion seal; Its reinforced seal (5) inner ring is equipped with location O type circle (6), and location O type circle (6) is by reinforced seal (5) inner ring and arbor automatic positioning seal.
By adopting technique scheme, thoroughly solved spring type mechanical sealing at start, the leakage problem that causes when shutting down, and make that it is simple in structure, volume-diminished, cost reduce, installation and maintenance are convenient especially, and have increased the working life of pump greatly.
The drawing explanation:
Fig. 1 is the opposed type U profile of a present invention magnetic mechanical seal structural representation:
Among the figure one. stationary ring two. rotating ring three. the rotating ring mounting hole
Four. rotating ring magnetic bead five. reinforced seal six. location O type circle
Seven. stationary ring positioning hole eight. sealing gasket nine. the stationary ring face
Ten .U profiles 11. stationary ring mounting hole 12. the stationary ring magnetic bead
The specific embodiment mode:
Be that example is illustrated in conjunction with this figure with the pump magnetic mechanical seal below: as shown in fig. 1, the opposed adhesive of rotating ring magnetic bead (4) of the stationary ring magnetic bead (12) of stationary ring (1) and rotating ring (2), by U profile (10) rotation positioning, make stationary ring face (9) and U profile (10) form the Double End inclusion seal; Its stationary ring (1) is fixed on the electric motor end cap by stationary ring positioning hole (7) and sealing gasket (8) by retaining screw, forms the integral sealing of stationary ring and end cap; Its location O type circle (6) is fixed on osteomere sealing (5) on the pump shaft, and by the automatic location of osteomere sealing (5), form the sealing of reinforced seal and pump shaft body, the present invention is when installing and changing this Sealing, only need take off location O type circle (6) rotating ring (2) integral body is put into, load onto location O type circle (6) then and get final product.
The present invention is simple in structure, cheap, installation and maintenance are convenient especially, can be widely used in fields such as all kinds of pumps, still, speed reducer, ventilator, blower.
