Be equipped with the collection and load the workbin between the pump body and axle, the collection loads the workbin suit and on the axle sleeve, collects the annulus formation packing chamber who loads between workbin and the axle sleeve, the filler is located among the packing chamber, gland fixed mounting is with packing seal on the collection loads the workbin, the collection loads the workbin, and to pass through bolt and the pump body fixed, at the epaxial location annular that is equipped with, set screw radially passes and inserts the holding ring inslot behind the axle sleeve. The utility model discloses the whole quick replacement of the part of can realizing packing shortens the down time of pump, reduces the maintenance work volume.
Description
Technical field
The utility model relates to sealing configuration, is specifically related to a kind of cartridge packing seal structure, belongs to technical field of sealing technology.
Background technique
Packing seal uses in a large number on rotary machine, and filler is in the long-play process of machinery, and wearing and tearing are inevitable, and just needs to change once wearing and tearing.Fig. 1 is a kind of situation of prior art packing seal structure, and mainly comprise axle 1, axle sleeve 3, the pump housing 4, filler 6, Gland 7 and locking nut 9, assembling sleeve 3 on axle 1, is provided with O RunddichtringO 8 between axle sleeve 3 and axle 1.Axle sleeve 3 two ends are fixed on axle 1 by the shaft shoulder 2 and locking nut 9, and axle 1 drives axle sleeve 3 to rotate by flat key 5.Filler 6 is assemblied in the filler chamber of the pump housing 4, compresses filler 6 and realize sealing by the Gland 7 be fixed on the pump housing.In the course of the work, axle sleeve 3 and then axle 1 rotates pump together, and filler 6 is static, and this must cause the wear damage of filler and axle sleeve.When filler damage leakage increasing needs to change, present way is that filler is taken out the filler more renewed.Existing structure changes filler can only take out replacing piece by piece, and the at substantial time, engineering time is long, and pump is shut down for a long time, delays the operation of pump.If when axle sleeve 3 wearing and tearing need be changed, then inevitable overall disintegration pump could be changed.Along with social progress, cost of labor is more and more high, expending of engineering time, not only show that shutdown loss is large, and maintenance labour cost is also high.Reveal minimum in the pump operation of environmental protection requirement simultaneously, this just needs to solve the quick-replaceable problem of pump seal.
Model utility content
For prior art above shortcomings, the purpose of this utility model be to provide a kind ofly to change fast, cartridge packing seal structure that sealing wear is little.
For solving the problems of the technologies described above, the utility model have employed following technological scheme:
Cartridge packing seal structure, comprises axle, axle sleeve, the pump housing, filler and Gland; Axle sleeve to be sleeved on axle and to be connected by key and realizes synchronous axial system, it is characterized in that: between the pump housing and axle, be provided with collection filling hopper, collection filling hopper is sleeved on axle sleeve, and the annulus between collection filling hopper and axle sleeve forms filler chamber, and described filler is located in filler chamber; Gland is fixedly mounted on collection filling hopper with by packing seal; Collection filling hopper is fixed by bolt and the pump housing; Axle is provided with positioning ring groove, and positioning screwn inserts in positioning ring groove radially across after axle sleeve.
For enhanced leaktightness, between described collection filling hopper and the pump housing, be provided with seal ring; Also seal ring is provided with between axle sleeve and axle.
Compared with prior art, the utility model has following beneficial effect:
1. this structure realizes the overall quick-replaceable of packing elements, shortens the dead time of pump, reduces maintenance load.
2. this structure has been assembled at entire plant, makes full use of the professional advantage of device fabrication enterprise, and filler is pressed to suitable degree, has both ensured gland sealed reliability, ensures that again the wearing and tearing sealed drop to bottom line.
3. the location of this designs simplification to axle sleeve, prior art needs the thread section is connected with for locking nut the axle processing shaft shoulder, and this structure is only processed annular groove and namely located by positioning screwn, and compacter.
Accompanying drawing explanation

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model design philosophy is reached rapid-maintenance pump by integral replacing packing seal and ensures the reliable object of sealing.Specific implementation structure is see Fig. 2, and upper as can be seen from figure, the utility model cartridge packing seal structure, comprises axle 1, axle sleeve 2, the pump housing 3, filler 7 and Gland 8; Axle sleeve 2 to be sleeved on axle 1 and to be connected by flat key 4 and realizes synchronous axial system.Between the pump housing 3 and axle 1, be provided with collection filling hopper 6, collection filling hopper 6 is sleeved on axle sleeve 2, and the annulus between collection filling hopper 6 and axle sleeve 2 forms filler chamber, and described filler 7 is located in filler chamber.Gland 8 is fixedly mounted on collection filling hopper 6 by clamping bolt 12 to be sealed by filler 7; Collection filling hopper 6 is fixed by connecting bolt 9 and the pump housing 3.Axle 1 is provided with positioning ring groove 11, and positioning screwn 10 inserts in positioning ring groove 11 radially across after axle sleeve 2.
For enhanced leaktightness, between described collection filling hopper 6 and the pump housing 3, be provided with O RunddichtringO 5; Also O RunddichtringO 5 is provided with between axle sleeve 2 and axle 1.
The central idea of technical solutions of the utility model is that clamping bolt 12 set of gland sealed axle sleeve 2, filler 7, collection filling hopper 6, Gland 8 and compression filler is assembled into a whole assembly, this whole assembly is assembled on running shaft 1, located on axle by positioning screwn 10, drive axle sleeve 2 to rotate by flat key 4, thus realize sealing.Once filler or axle sleeve wearing and tearing, only need to unclamp connecting bolt 9, namely this whole assembly replaceable, therefore keeps in repair rapidly and efficiently.
Compared with prior art, the utility model has following beneficial effect:
1. this structure realizes the overall quick-replaceable of packing elements, shortens the dead time of pump, reduces maintenance load.
2. this structure has been assembled at entire plant, makes full use of the professional advantage of device fabrication enterprise, and filler is pressed to suitable degree, has both ensured gland sealed reliability, ensures that again the wearing and tearing sealed drop to bottom line.
3. the location of this designs simplification to axle sleeve, prior art needs the thread section is connected with for locking nut the axle processing shaft shoulder, and this structure is only processed annular groove and namely located by positioning screwn, and compacter.
What finally illustrate is, above-described embodiment is only unrestricted for illustration of the technical solution of the utility model, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
