Description
Technical field
The utility model relates to a kind of seal arrangement, relates in particular to a kind of mechanical seal device.
Background technique
Along with the development of society, a large amount of mechanical rotating devices are used, and these equipment unavoidably are provided with seal arrangement.Seal arrangement can effectively reduce the leakage of medium between power input shaft and housing, thereby reduces mechanical energy consumption, improves the unit input and output, and the working life of prolonged mechanical.
General seal arrangement (as shown in Figure 1) comprises power input shaft 1, housing 2, axle sleeve 3, spring seat 4, throw-out collar 5, compensated ring adaptor 6, rotating ring 7, stationary ring 8, Cock screw 9, spring 10, transmission screw 11, driving pin 12 and seal ring 13, power input shaft 1 passes shell 2 bodies, be arranged in the housing 2, power input shaft 1 overcoat has axle sleeve 3, the axle sleeve 3 outer spring seats 4 that are provided with successively, throw-out collar 5, compensated ring adaptor 6, rotating ring 7 and stationary ring 8, stationary ring 8 is near the end of housing 1, spring seat 4 is fixed on the axle sleeve 3 by Cock screw 9,5 of spring seat 4 and throw-out collars are provided with spring 10 and transmission screw 11, throw-out collar 5 is connected by driving pin 12 with compensated ring adaptor 6,2 of stationary ring 8 and housings are provided with seal ring 13, and 2 on compensated ring adaptor 6 and axle sleeve are provided with seal ring.When power input shaft rotated, rotating ring can rotate thereupon, and stationary ring is transfixion then, and in the effect of spring, both fit together, and form relative radial rotating, can form oil film during rotation, play the effect of sealing.
But, can contain solid impurity in the medium in housing, when seal arrangement ran up, these solid impurities can inevitably enter seal face, destroyed the continuity of oil film; Simultaneously, solid impurity also can produce inhibitory action to spring, has affected the floatability of compensated ring adaptor, has reduced sealing effect, causes seal failure.
The model utility content
The utility model purpose is to provide a kind of can prevent because containing the seal arrangement of the seal failure that solid impurity causes in the medium in the housing in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of seal arrangement, comprise power input shaft, housing, axle sleeve, spring seat, throw-out collar, compensated ring adaptor, rotating ring, stationary ring, Cock screw, spring, the transmission screw, driving pin and seal ring, described power input shaft passes housing, be arranged in the housing, described power input shaft overcoat has axle sleeve, described axle sleeve is provided with spring seat outward successively, throw-out collar, compensated ring adaptor, rotating ring and stationary ring, described stationary ring is near the end of housing, described spring seat is fixed on the axle sleeve by Cock screw, be provided with spring and transmission screw between described spring seat and throw-out collar, described throw-out collar is connected by driving pin with compensated ring adaptor, be provided with seal ring between described stationary ring and housing, described compensated ring adaptor and shaft room are provided with seal ring, and described spring overcoat has the isolation flexible pipe; Be provided with insulating liquid in the described housing.
Because the utilization of technique scheme, the utility model compared with prior art has following advantages:
Seal arrangement of the present utility model because spring overcoat has the isolation flexible pipe, has played the effect of spacer spring, has avoided solid impurity and spring contact, so that solid impurity can not produce inhibitory action to spring, the floatability of compensated ring adaptor can not be affected; Owing to be provided with insulating liquid in the housing, solid impurity can incorporate in the insulating liquid, can not destroy the continuity of oil film, can prevent because containing the seal failure that solid impurity causes in the medium in the housing again.
Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1 is the structural representation of the seal arrangement of prior art;
Accompanying drawing 2 is the structural representation of seal arrangement of the present utility model;
Wherein: 1, power input shaft; 2, housing; 3, axle sleeve; 4, spring seat; 5, throw-out collar; 6, compensated ring adaptor; 7, rotating ring; 8, stationary ring; 9, Cock screw; 10, spring; 11, transmission screw; 12, driving pin; 13, seal ring; 14, isolation flexible pipe; 15, insulating liquid.
Embodiment
The utility model is described in further detail below in conjunction with drawings and the specific embodiments.
Described in the utility model a kind of seal arrangement as shown in Figure 2, comprise power input shaft 1, housing 2, axle sleeve 3, spring seat 4, throw-out collar 5, compensated ring adaptor 6, rotating ring 7, stationary ring 8, Cock screw 9, spring 10, transmission screw 11, driving pin 12 and seal ring 13, power input shaft 1 passes shell 2 bodies, be arranged in the housing 2, power input shaft 1 overcoat has axle sleeve 3, the axle sleeve 3 outer spring seats 4 that are provided with successively, throw-out collar 5, compensated ring adaptor 6, rotating ring 7 and stationary ring 8, stationary ring 8 is near the end of housing 1, spring seat 4 is fixed on the axle sleeve 3 by Cock screw 9,5 of spring seat 4 and throw-out collars are provided with spring 10 and transmission screw 11, throw-out collar 5 is connected by driving pin 12 with compensated ring adaptor 6,2 of stationary ring 8 and housings are provided with seal ring 13,2 on compensated ring adaptor 6 and axle sleeve are provided with seal ring, and described spring 10 overcoats have isolation flexible pipe 14; Be provided with insulating liquid 15 in the described housing 2.
Seal arrangement of the present utility model, because spring 10 overcoats have isolation flexible pipe 14, have played the effect of spacer spring 14, have avoided solid impurity to contact with spring 14, so that solid impurity can not produce inhibitory action to spring 14, the floatability of compensated ring adaptor 6 can not be affected; Owing to be provided with insulating liquid 15 in the housing 2, solid impurity can incorporate in the insulating liquid 15, can not destroy the continuity of oil film again, can prevent because containing the seal failure that solid impurity causes in the medium in the housing 2.
