Description
Technical field:
The utility model relates to a kind of seal arrangement, specifically is a kind of integrated mechanical sealing that is contained in the chemical flow-process pump.
Background technique:
So-called integrated mechanical sealing is exactly that all scattered component collection in the conventional mechanical sealing are fitted together, and makes it become an aggregate, can self-contained whole tearing open when needing.Three positioning plates that the tradition integrated mechanical sealing generally includes fastening ring, axle sleeve, moving ring assembly, static components and is used for moving ring assembly and static components collection are fitted together, after the user packed into this integrated mechanical sealing between pump shaft and the pump case, three positioning plates of dismantling can make the chemical-process pump work.Though above-mentioned integrated mechanical sealing is widely adopted, but still there are following two defectives in it in actual application: 1, fastening ring and three positioning plates generally all are exposed axle sleeve one ends that is contained in, for satisfying the installation requirement of fastening ring and three positioning plates, it is long that the axial dimension of axle sleeve is generally all made, and this can increase the volume of existing integrated mechanical sealing undoubtedly, in addition, long axle sleeve also relatively takes material; 2, existing integrated mechanical sealing needs to remove three positioning plates after packing between pump shaft and the pump case, and it is all long usually to remove time of three positioning plates, and this makes troubles for user's on-the-spot fitting operation.
The model utility content:
The technical problems to be solved in the utility model is, provides a kind of axial dimension short, and volume is less, and on-the-spot fitting operation is the chemical flow-process pump integrated mechanical sealing easily.
Technical solution of the present utility model is, provide a kind of chemical flow-process pump integrated mechanical sealing with following structure: comprise moving ring assembly and static components, static components comprises sealing gland and stationary ring, stationary ring is contained in sealing gland inner chamber one end, have the water inlet irrigation channel and the water outlet irrigation channel that communicate with the sealing gland inner chamber on the sealing gland, moving ring assembly comprises rotating ring, rotating seat, spring and spring seat, rotating ring is contained on the rotating seat and with stationary ring to be close to, wherein, have the annular groove that snaps in for Cock screw on the sealing gland inner chamber left part perisporium, rotating ring, rotating seat, spring and spring seat all are arranged in the sealing gland inner chamber, the spring seat right part is arranged in the rotating seat inner chamber, be evenly equipped with a plurality of projectioies for transmitting torque on the spring seat right-hand member periphery wall, have a plurality of axial grooves for the projection insertion on the rotating seat inner chamber perisporium, spring withstands between spring seat right-hand member and the rotating seat, be connected with a plurality ofly be used to the Cock screw that is pressed on the pump shaft on the spring seat left end perisporium, the water outlet irrigation channel communicates with annular groove.
Chemical flow-process pump integrated mechanical sealing described in the utility model wherein, is provided with seal ring and is used for preventing the split washer that seal ring is deviate to the right between rotating seat and the spring seat.
After adopting above structure, compared with prior art, the utility model chemical flow-process pump has following two advantages with integrated mechanical sealing:
1, during the collection dress, with rotating ring, rotating seat, spring, spring seat, Cock screw and stationary ring are put into the inner chamber of sealing gland, lodging the water outlet irrigation channel can directly use spanner that Cock screw is operated, pine moves back Cock screw, after its head snaps in the annular groove, moving ring assembly and static components are just assembled and are fitted together, form integrated mechanical sealing, this obviously adopts three positioning plates and fastening ring to cause the axle sleeve axial dimension long different with the prior art integrated mechanical sealing, the utility model chemical flow-process pump saves three positioning plates with integrated mechanical sealing, fastening ring and long axle sleeve, and adopt Cock screw to be stuck in the mode of annular groove with rotating ring, rotating seat, spring, spring seat, Cock screw and stationary ring deflation are hidden in the inner chamber of sealing gland, this concealed structure has shortened the axial dimension of the utility model chemical flow-process pump with integrated mechanical sealing greatly, respective volume also reduces thereupon, has saved material;
2, the utility model chemical flow-process pump with integrated mechanical sealing after packing between pump shaft and the pump case, the user need not to remove three positioning plates again as existing integrated mechanical sealing, only need lodge the water outlet irrigation channel again and use spanner that Cock screw is tightened on the pump shaft clockwise and get final product, like this, chemical flow-process pump just can have been started working, by this structure, saved the time that the user removes three positioning plates, convenient greatly on-the-spot fitting operation.
Description of drawings:
To be the utility model chemical flow-process pump look sectional structure chart with the master of integrated mechanical sealing to Fig. 1;
Fig. 2 is that the location inserted sheet is inserted in the master of the utility model chemical flow-process pump with between sealing gland in the integrated mechanical sealing and the spring seat time and looks sectional structure chart.
Embodiment:
Below in conjunction with the drawings and specific embodiments the utility model chemical flow-process pump is described in further detail with integrated mechanical sealing:
As shown in Figure 1, in this embodiment, the utility model chemical flow-process pump comprises moving ring assembly and static components with integrated mechanical sealing, static components comprises sealing gland 4 and stationary ring 12, stationary ring 12 is contained in sealing gland 4 inner chamber right-hand members by bearing pin 14, have the water inlet irrigation channel 15 and the water outlet irrigation channel 3 that communicate with sealing gland 4 inner chambers on the sealing gland 4, have the annular groove 8 that snaps in for Cock screw 6 on the sealing gland 4 inner chamber left part perisporiums, sealing gland 4 left ends are bonded with pad 5 by glue, moving ring assembly comprises rotating ring 11, rotating seat 9, spring 10 and spring seat 7, rotating ring 11, rotating seat 9, spring 10 and spring seat 7 all are arranged in sealing gland 4 inner chambers, rotating ring 11 is contained in rotating seat 9 right-hand members and is close to stationary ring 12, spring seat 7 right parts are arranged in rotating seat 9 inner chambers, be provided with seal ring 1 between rotating seat 9 and the spring seat 7 and be used for preventing the split washer 18 that seal ring 1 is deviate to the right, be evenly equipped with a plurality of projectioies 17 for transmitting torque on the spring seat 7 right-hand member periphery walls, have a plurality of axial grooves 16 for projection 17 insertions on the rotating seat 9 inner chamber perisporiums, spring 10 withstands between spring seat 7 right-hand members and the rotating seat 9, be connected with three Cock screws 6 that are used for being pressed on the pump shaft 13 on the spring seat 7 left end perisporiums, three Cock screws 6 evenly distribute along circumference, water outlet irrigation channel 3 communicates with annular groove 8, the utility model chemical flow-process pump before not using, all is equipped with dustproof plug 2 on water outlet irrigation channel 3 and the water inlet irrigation channel 15 with integrated mechanical sealing.
